Background: Challenges in temporomandibular joint (TMJ) arthroscopy training include the cost of operating room time, surgical risks, and the accessibility of cadavers and high-fidelity simulators. A low-fidelity simulator (LFS) was developed for initial TMJ arthroscopy training., Purpose: The aim of this study was to evaluate improvement in TMJ arthroscopic skills after training with an LFS using the Arthroscopic Surgical Skill Evaluation Tool (ASSET) global rating scale., Study Design, Setting, Sample: A prospective randomized controlled study was conducted. Subjects included Oral and Maxillofacial Surgery residents in postgraduate year 1-5 at Thomas Jefferson University. Chief residents actively performing TMJ arthroscopy were excluded., Predictor Variable: The predictor variable was participation in LFS training. Subjects were randomly assigned to the LFS training or no LFS training group., Main Outcome Variables: The primary outcome variable was simulated surgical skill measured by total ASSET score (maximum score of 35). The secondary outcome variables were simulated surgical skill measured by each ASSET domain score and time to completion., Covariates: The covariates included sex, age, handedness, postgraduate year, endoscopic experience, open TMJ surgery experience, and experience with musical instruments and sports., Analyses: Data analyses included paired T-tests to determine changes in outcome variables after TMJ arthroscopy training between experimental groups, and ANOVA and χ 2 tests to identify associations between covariates. Inter-rater reliability of the blinded examiners was evaluated using Cronbach's alpha correlation. A P-value < .05 was considered significant., Results: The sample was composed of 10 residents: 5 (100%) males in the no LFS group, 3 (60%) males, and 2 (40%) females in the LFS group (P = .4). There was no significant difference between the groups in pre-TMJ arthroscopy training ASSET scores (P = .3). After training, the total ASSET score improved by 3.40 ± 6.87 in the no LFS group and by 6.27 ± 2.68 in the LFS group (P = .03)., Conclusions and Relevance: Study results showed that low-fidelity simulation can improve fundamental arthroscopic skills. Future research should be conducted on a larger scale to further validate this model and show the transfer of skill improvements to cadaver and live patient settings., (Copyright © 2024 American Association of Oral and Maxillofacial Surgeons.

Purpose: Skilful arthroscopy requires an aboveaverage level of manual dexterity. It is evident that particular motor skills can be learned and trained before arthroscopic training. The aim of this prospective cohort study was to investigate the impact of movement-related cognitive training on the learning curve during arthroscopic basic training., Methods: Fifty right-handed participants without arthroscopic experience were matched to an intervention group (n = 25) and a control group (n = 25). Prior to basic arthroscopic skill training with a simulator, the intervention group underwent 12 weeks of movement-related cognitive training. Cognitive and motor skills were assessed in both groups by using standardised tests (CogniFit test, angle reproduction test, two-arm coordination test) as a pretest and, for the intervention group, again before arthroscopic training as a posttest. For arthroscopic simulator training, three tasks ('Telescoping', 'Periscoping', 'Triangulation') from the Fundamentals of Arthroscopic Surgery Training module were selected and practiced 10 times with the camera in the right and left hands. The learning progress was quantified by exercise time, camera path length and hook path length., Results: No significant differences in sex distribution, age distribution or the results of the pretests between the intervention group (n = 21) and the control group (n = 25) were found (n.s.). The intervention group improved significantly from the pretest to the posttest in the CogniFit (p = 0.003) and two-arm coordination test in terms of time (p < 0.001) and errors (p = 0.002) but not in the angle reproduction test. No significant differences were found between the groups for the three arthroscopic tasks., Conclusion: The hypothesis that movement-related cognitive training shortens the learning curve for acquiring arthroscopic basic skills cannot be confirmed. Other factors influencing the learning curve such as talent, teaching method and motivation have a greater impact on the acquisition of complex motor skills., Level of Evidence: Level II., (© 2024 The Author(s).

Purpose: This work presents FASTRL, a benchmark set of instrument manipulation tasks adapted to the domain of reinforcement learning and used in simulated surgical training. This benchmark enables and supports the design and training of human-centric reinforcement learning agents which assist and evaluate human trainees in surgical practice., Methods: Simulation tasks from the Fundamentals of Arthroscopic Surgery Training (FAST) program are adapted to the reinforcement learning setting for the purpose of training virtual agents that are capable of providing assistance and scoring to the surgical trainees. A skill performance assessment protocol is presented based on the trained virtual agents., Results: The proposed benchmark suite presents an API for training reinforcement learning agents in the context of arthroscopic skill training. The evaluation scheme based on both heuristic and learned reward functions robustly recovers the ground truth ranking on a diverse test set of human trajectories., Conclusion: The presented benchmark enables the exploration of a novel reinforcement learning-based approach to skill performance assessment and in-procedure assistance for simulated surgical training scenarios. The evaluation protocol based on the learned reward model demonstrates potential for evaluating the performance of surgical trainees in simulation., (© 2024. The Author(s).)

Objectives: Negative emotions affect not only the physical health of residents but also the performance of surgical skills. Mindfulness training has been shown to be effective in improving mood. However, few studies have explored its effect on surgical skill performance. We aimed to investigate the effect of mindfulness training on knee arthroscopy skill performance., Design: We recruited 30 participants for knee arthroscopy skills training (Tasks 1-7) on a simulator, after which a pretest (Tasks 8 and 9) was conducted to test their skill performance and psychological states (including mindfulness state, anxiety, stress, and depression). Then, they were randomly assigned into 2 groups: the intervention group underwent 2 weeks of mindfulness training while the control group received no intervention. All participants were asked to retrain their skills 1 week after completing the initial arthroscopy skill training. After the 2-week mindfulness training intervention, a post-test was performed to detect the difference in skill performance and psychological states between 2 groups. We used the fNIRS device to record prefrontal cortex activation during the post-test., Setting: The study was carried out at the Zhujiang Hospital of Southern Medical University., Participants: 30 novice orthopedic residents., Results: A total of 30 residents completed all the study programs. We did not observe differences in arthroscopy skill performance at pretest. Compared with the control group, the intervention group showed significant improvement in total score of Task 8 (p = 0.034) and 9 (p = 0.002), as well as significant relief in anxiety (p = 0.037) and stress (p = 0.027) symptoms but no improvement in depression (p = 0.828). No statistical difference in 2 groups was observed on the activation of the left prefrontal cortex (p = 0.68)., Conclusions: Two weeks of mindfulness training can improve arthroscopy skill performance while alleviating anxiety and reducing stress in novice residents. Mindfulness training may be an effective adjunct to surgical skill training., Trial Registration: Chinese Clinical Trial Registry, Number: ChiCTR2200058144., (Copyright © 2024 Association of Program Directors in Surgery.

Introduction: In 2019, the French College of Orthopaedic and Traumatology (CFCOT) made the AOTrauma course entitled "Basic Principles of Fracture Treatment" mandatory for all orthopaedic residents during the first year of their educational program i.e. during the SOCLE phase (common base phase). The objective of the evaluation was to determine which factors influenced the results of the practical work, according to the characteristics of the students and their experiences in laparoscopy or in arthroscopy in the operating theatre or on the simulator for arthroscopy., Material and Methods: In 2019 a total of 121 residents were included, corresponding to the full promotion. They filled out a preliminary questionnaire giving information on their general characteristics. Eight different workshops were evaluated. The grading of skills was as follows: "A" for "acquired", "B" for "in progress" and "C" for "not acquired". The data was collected on a computerized spreadsheet. The statistical analysis used the Welch test, the Chi2 test and the Fisher test., Results: The average "A" percentage across all workshops was 87.8%. Factors predictive of a good result were experience in laparoscopy as the main operator (p = 0.014) and male sex (p = 0.014). We observed that the residents who had not performed arthroscopy in clinical practice had done more training on simulators than the others (p = 0.044). Residents who had performed at least one arthroscopy as a main operator were predominantly female (p < 0.001)., Discussion: The interest of this study lies in the novelty of the analysis of the results of a whole promotion of residents in the SOCLE phase in osteosynthesis simulation., Conclusion: This novel evaluation deserves to be repeated by refining the evaluation tools before and during the course. It allowed us to know the weak points of the students during the simulated learning.

Background: Arthroscopy proficiency is key to being a competent orthopaedic surgeon and acquiring arthroscopic skills takes years of exposure and diligent practice. However, today's graduating consultants have had considerably less time in operating theatre than their senior colleagues at the same point of their careers., Objectives: To evaluate whether: (1) Students could improve their arthroscopic technique using a low fidelity arthroscopic training tool (2) students enjoyed the use of the simulator (3) If certain demographics correlate to performance on the simulator., Methods: Medical students who have no previous training in arthroscopy were included. A combined left- and right-handed timed run with a low-fidelity arthroscopic triangulation simulator was recorded before and after 40-minutes of practice., Results: 84 participants took part with an average improvement of was 66.8%. Students felt that their arthroscopic skills increased on average by 36.4%. 73 of the 84 participants gave the maximum score of 5 when asked if they enjoyed the session and 74 participants gave the maximum score of 5 as to whether they would be interested in participating in further sessions. Factors such as biological sex, video game play and sports were found to be statistically significant to performance., Conclusions: This study showed a statistically significant improvement in students' arthroscopic performance with a low-fidelity arthroscopic simulator. Students found the experience useful with the vast majority indicating interest in completing further training sessions to help improve practical surgical skills. Video gamers, sports players and males were found to have a correlation with performance on the simulator., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Simulation-based training is required by many medical specialties. Barriers, however, have prevented widespread implementation of simulators for arthroscopic training. The advantages of arthroscopic simulator-based training of residents include decreased errors, decreased cost of training, and improved patient care. Before an educational program can focus on the type of simulator, it is essential to have a validated curriculum and framework for how to use those simulators. One of the most validated systems is called proficiency-based progression training. Proficiency-based progression is essentially a paradigm in which basic skills must be mastered and demonstrated via objective evaluation, before moving on to more advanced skills. There are a variety of different validation methods and tools that have been described, with the Arthroscopic Surgical Skill Evaluation Tool being the most widely used tool. It is essential that any simulator has evidence and validation that it will ultimately improve surgical skills in the operating room. In the future, emerging technologies such as virtual reality, augmented reality, and three-dimensional printing will likely play a major role in the creation of newer simulators and may improve access to residents throughout the world.

Purpose: To systematically review the current literature on the effectiveness of hip arthroscopy simulation training and to determine the consistency of reporting and validation of simulation used in hip arthroscopy., Methods: Three databases (PubMed, EMBase, and CINAHL) were screened using PRISMA guidelines in January 2022 for published literature on virtual simulation in hip arthroscopy. Studies reporting on the use of hip arthroscopy simulation training in orthopedic surgical trainees were included and assessed for quality and risk of bias using MINORS criteria. The number of participants, participant education level, experience, simulator type, validation type, method of assessment, and simulation outcomes were extracted from included studies., Results: Of the 286 articles screened, 11 met inclusion criteria for review evaluating 323 orthopedic trainees with a mean of 29.36 participants per study published between 2012 and 2021, most commonly in the United Kingdom (55%). The four most reported surgical skills evaluated were visualization and probing tasks (82%), mean time to perform the task (73%), number of cartilage and soft tissue collisions (73%), and number of hand movements (73%). The most described measurement instruments included a simulation built-in scoring system (55%), Arthroscopic Surgical Skill Evaluation Tool (ASSET) Global Rating Scale (GRS) (27%), and motion analysis system (18%). Construct validity was the most reported overall type of validity (82%), followed by face validity (36%), transfer validity (18%) and content validity (18%). Construct validity was also the most reported validity for the simulator and measurement instrument (55% and 89%, respectively)., Conclusions: There is significant variation in reported learning outcomes and measurement instruments for evaluating the effectiveness of hip arthroscopic-based education. This study highlights that simulation training may be an effective tool for evaluation of hip arthroscopy skills., Level of Evidence: Level III, systematic review of level I to III studies., (Copyright © 2023 Arthroscopy Association of North America.

Introduction: Arthroscopic training includes successive stages of observation, reproduction and then repetition. Learning through simulation in 2D virtual reality makes it possible to repeat these different stages to enhance the learner's experience in complete safety and a shorter timeframe. Some procedures require inversion of the optical and instrumental approaches in the axial plane, disrupting the existing psychomotor and technical skills. The objective of this study was to compare the degree of difficulty and the distribution of results for the same exercise carried out alternately in classical holding and inverted holding of the instruments in a cohort of novice learners., Materials and Methods: Twenty-two medical students, novices in arthroscopic surgery, participated in the study. Each performed an exercise consisting of grasping ten targets with arthroscopic forceps and placing them in a basket on the VirtaMed ArthroS™ simulator. The exercise was performed with the scope and grasping instrument pointed away from the operator, "catch the stars front" (CTSF), then directed towards the operator, "catch the stars back" (CTSB). The simulator recorded several parameters making up an overall composite score ("overall performance score", OPS) out of 120 points. Voluntary abandonment of the exercise was also collected., Results: All students completed the CTSF exercise but 6 dropped out of the CTSB exercise (27%, p=0.01). In the CTSF exercise, the average OPS was higher with 45.9 points versus 22.8 points in the CTSB exercise (p<0.001). By detailing the components of the OPS score, the parameters of interest on the Fundamentals of Arthroscopic Training (FAST) module of the simulator included: the distance traveled by the scope and the grasping forceps was significantly greater in the CTSB group (p<0.001), the duration of the exercise was significantly greater in the CTSB group (p<0.001), the time spent with the instruments in the videoscopic field was significantly lower in the CTSB group (p=0.001) and finally the absence of a significant difference in the camera alignment compared to the horizontal plane between the two groups., Conclusion: The exercise with the instruments directed towards the operator is more difficult with a greater distribution for all the secondary criteria except for the camera alignment, which suggests that it could be more discriminating. The dropout rate is also higher. It would therefore be interesting to introduce CTSB type training in initial training programs in arthroscopy., Level of Evidence: III, comparative prospective study., (Copyright © 2023 Elsevier Masson SAS.

Purpose: To compare the effect of three differently spaced retraining schedules (1-day, 2-day, and 1-week intervals) on the acquisition of basic arthroscopic skills and skill retention after 3 months., Methods: Thirty orthopaedic residents without arthroscopic experience were enrolled in a double-blind, randomised, parallel-controlled trial. Spaced retaining schedules were divided into massed training and retraining phases. Participants were required to obtain perfect scores in all tasks on the simulator in the massed training phase, followed by a pretest to evaluate the training effect. During the retraining phase, participants were randomly assigned to Groups A (1-day interval), B (2-day interval) or C (1-week interval). A posttest was used to evaluate the effect of different retraining patterns. Follow-up evaluations were conducted at 1 week, 1 month and 3 months after the completion of spaced retraining schedules to measure skill retention. One-way ANOVA and paired-sample t tests were used for statistical analysis., Results: Significant between-group differences in diagnostic arthroscopy (137.0 ± 24.8 vs. 140.1 ± 21.3 vs. 175.3 ± 27.4 s, P (A-C)  = 0.005, P (B-C)  = 0.010) and loose body removal (193.1 ± 33.9 vs. 182.0 ± 32.1 vs. 228.7 ± 42.9 s, P (B-C)  = 0.025) completion times were observed. No significant differences were found in other posttest metrics. An assessment of skill retention after the 3-month follow-up (Evaluation 3) showed significant differences in diagnostic arthroscopy completion time (202.5 ± 53.3 vs. 172.0 ± 27.2 vs. 225.5 ± 42.1 s, P (B-C)  = 0.026). No significant differences were found in other Evaluation 3 metrics., Conclusion: The 2-day retraining schedule was the most effective for the acquisition and retention of basic arthroscopic skills and could be integrated into arthroscopic skills curricula. After a 3-month follow-up, residents who followed this schedule showed better skill retention than those who followed the 1-week interval schedule., Level of Evidence: Level I., (© 2023.

Purpose: Virtual arthroscopic training has become increasingly popular. However, there is a lack of efficiency-based tracking of the trainee, which may be critical for determining the specifics of training programs and adapting them for the needs of each trainee. This study aims to evaluate and compare the measures obtained with a non-invasive neurophysiological method with The Diagnostic Arthroscopy Skill Score (DASS), a commonly used assessment tool for evaluating arthroscopic skills., Methods: The study collected simulator performance scores, consisting of "Triangulation Right Hand", "Triangulation Left Hand", "Catch the Stars" and "Three Rings" and DASS scores from 22 participants (11 novices, 11 experts). These scores were obtained while participants underwent a structured program of exercises for the fundamentals of arthroscopic surgery training (FAST) and knee module using a simulator-based arthroscopy device. During the evaluation, data on oxy-hemoglobin and deoxy-hemoglobin levels in the prefrontal cortex were collected using the Functional Near-Infrared Spectroscopy (fNIRS) imaging system. Performance scores, DASS scores, and fNIRS data were subsequently analyzed to determine any correlation between performance and cortex activity., Results: The simulator performance scores and the DASS Part2 scores were significantly higher in the expert group compared to the novice group (200.1 ± 28.5 vs 172.5 ± 48.9, p = 0.04 and 9.4 ± 5.6 vs. 5.4 ± 5.6 p = 0.02). In the expert group, fNIRS data showed a significantly lower prefrontal cortex activation during fundamental tasks in the FAST module, indicating significantly more efficient mental resource use., Conclusion: The analysis of cognitive workload changes during simulation-based arthroscopy training revealed a significant correlation between the trainees' DASS scores and fNIRS data. This correlation suggests the potential use of fNIRS data and DASS scores as additional metrics to create adaptive training protocols for each participant. By incorporating these metrics, the training process can be optimized, leading to more efficient arthroscopic training and better preparedness for clinical operations., Level of Evidence: III., (© 2023.

Purpose: It is reasonable to question whether the case volume is a suitable proxy for the manual competence of an arthroscopic surgeon. The aim of this study was to evaluate the correlation between the number of arthroscopies previously performed and the arthroscopic skills acquired using a standardized simulator test., Methods: A total of 97 resident and early orthopaedic surgeons who participated in arthroscopic simulator training courses were divided into five groups based on their self-reported number of arthroscopic surgeries: (1) none, (2) < 10, (3) 10 to 19, (4) 20 to 39 and (5) 40 to 100. Arthroscopic manual skills were evaluated with a simulator by means of the diagnostic arthroscopy skill score (DASS) before and after training. Seventy-five points out of 100 must be achieved to pass the test., Results: In the pretest, only three trainees in group 5 passed the arthroscopic skill test, and all other participants failed. Group 5 (57 ± 17 points; n = 17) scored significantly higher than the other groups (group 1: 30 ± 14, n = 20; group 2: 35 ± 14, n = 24; group 3: 35 ± 18, n = 23; and group 4: 33 ± 17, n = 13). After a two-day simulator training, trainees showed a significant increase in performance. In group 5, participants scored 81 ± 17 points, which was significantly higher than the other groups (group 1: 75 ± 16; group 2: 75 ± 14; group 3: 69 ± 15; and group 4: 73 ± 13). While self-reported arthroscopic procedures were n.s. associated with higher log odds of passing the test (p = 0.423), the points scored in the pretest were found to be a good predictor of whether a trainee would pass the test (p < 0.05). A positive correlation was observed between the points scored in the pretest and the posttest (p < 0.05, r = 0.59, r 2  = 0.34)., Conclusions: The number of previously performed arthroscopies is not a reliable indicator of the skills level of orthopaedic residents. A reasonable alternative in the future would be to verify arthroscopic proficiency on the simulator by means of a score as a pass-fail examination., Level of Evidence: III., (© 2023.

Purpose: Surgical training is crucial for orthopedics residents during their educational careers. Residents who follow classic training courses are less skilled than those trained with simulators. Virtual simulators are reported to be global learning tools for knee arthroscopy. The primary purpose of our study is to evaluate the current state of use of arthroscopic knee simulators and their actual effectiveness in transfer the skills learned in training to the operating theatre. The secondary purpose is to evaluate if the virtual simulators are better than the others in improve arthroscopic skills., Methods: Studies involving knee arthroscopy training with virtual reality simulators were included: a search of the literature from 2009 to September 2019 was performed on MEDLINE(PubMed) using PRISMA guidelines. Exclusion criteria were systematic review articles, aims and topics not related to the purpose of the study, single case and technical reports, biomechanical analysis, articles not in the English language, and editorial commentaries., Results: The literature review selected, nine studies and they included results on 93 residents, three expert surgeons and 189 medical students. All studies report improved arthroscopic skills after training with a simulator. Only four studies evaluated the transfer of arthroscopic skills of knee simulators to the operating theatre., Conclusions: Benchtop and Virtual Reality simulators are excellent tools for accelerating and improving arthroscopic training and skills acquisition. The second ones, high-cost, and fidelity simulators, seem to be the best of the two. A greater diffusion of Virtual Reality in universities is to be considered to improve residents' training and patients' clinical outcomes., (© 2021.

Purpose: To investigate whether novices could improve performance on a shoulder arthroscopic simulator (high-fidelity) through short-term training on a Fundamentals of Arthroscopic Surgery Training (FAST) simulator (low-fidelity)., Methods: Twenty-eight novices with no experience in arthroscopy were recruited to perform a pre-test on a shoulder arthroscopic simulator. Then they were randomized into two groups: the experimental group practiced five modules on the FAST simulator three times, and the control group did nothing. The experimental group performed a post-test immediately after FAST simulator practice. Control group rested for 70 minutes after experiencing pre-test before performing post-test. All parameters were recorded by the simulator., Results: The experimental group outperformed the control group in terms of total score, procedure time, camera path length, and grasper path length. However, there was no statistical difference in scratching of humerus cartilage or glenoid cartilage. Significant differences were found in the improvement of both groups in total score, procedure time, and camera path length., Conclusions: Arthroscopic skills gained after short-term training on FAST simulator could be transferred to the shoulder arthroscopic simulator. This research provides important evidence of the benefits of FAST simulator in shoulder arthroscopy training program.

Objective: The study aimed to examine the learning curve and short-term retention of arthroscopic skills acquired on a simulator., Design: Cohort study., Setting: Clinical Skills Training Center of Zhujiang Hospital of Southern Medical University PARTICIPANT AND METHODS: Orthopaedic residents (n = 14) without previous arthroscopy experience were included. After basic information was collected and an initial arthroscopy knowledge level test was administered, the subjects received standardised training on the simulator (day 1); then, they completed tasks on the simulator, including guided diagnostics (4 times), triangulation (5 times) and loose body removal (7 times). A learning curve for each skill was generated based on the total scores. The score of the last repetition of each task was the training level., Results: A total of 14 orthopedic residents were enrolled. All participants completed the training and testing. There was a learning curve over the course of training for all 3 arthroscopic skills (p < 0.001). On day 8 after the training, the mean score for guided diagnostics decreased from 49.9 to 48.9 (p = 0.001), and the retention rate was 97.8%. For triangulation, the mean total score decreased from 58.9 to 53.6 (p < 0.001), and the retention rate was 90.8%. For loose body removal, the mean total score decreased from 87.1 to 80.7 (p < 0.001), and the retention rate was 92.7%., Conclusions: Orthopaedic residents' arthroscopic skills learned through simulator training declined significantly in 1 week after the training, especially more difficult skills., (Copyright © 2022 Association of Program Directors in Surgery.

Introduction: With surgical opportunities becoming increasingly restricted for orthopaedic trainees, simulation training is a valuable alternative at providing sufficient practice. This pilot study aims to assess the potential effectiveness of low-fidelity simulation in teaching medical students basic arthroscopic skills and the feasibility of its incorporation into formal student training programmes., Methods: Twenty-two medical students completed pre- and post-training tests on the Probing (Task 1) and Maze (Task 2) exercises from the Sawbones 'Fundamentals of Arthroscopy Surgery Training' (FAST) programme. Training consisted of practising horizon control, deliberate linear motion and probing within 25min over a period of days. Completion time and error frequency were measured. The difference in performance was assessed using a paired two-tailed t -test. Qualitative data were collected., Results: Test completion time decreased significantly by a mean of 83s (±46s, 95% confidence intervals [CI] 37 to 129) for Task 1 ( p =0.001) and 105s (±55s, 95% CI 50 to 160) for Task 2 ( p =0.0007). Frequency of direct visualisation errors decreased significantly by a mean of 1.0 errors (±1.0 errors, 95% CI 0.1 to 2.0) for Task 1 ( p = 0.04) and 0.8 errors (±0.8 errors, 95% CI 0.1 to 1.6) for Task 2 ( p = 0.04). At post-training, 82% of participants were willing to incorporate FAST into formal training., Conclusions: Low-fidelity simulators such as FAST can potentially teach basic arthroscopic skills to medical students and are feasible for incorporation into formal training. They also give students a cost-effective and safe basic surgical training experience.

Background: Multiple assessment tools are used in arthroscopic training and play an important role in feedback. However, it is not fully recognized as to the standard way to apply these tools. Our study aimed to investigate the use of assessment tools in arthroscopic training and determine whether there is an optimal way to apply various assessment tools in arthroscopic training., Methods: A search was performed using PubMed, Embase and Cochrane Library electronic databases for articles published in English from January 2000 to July 2021. Eligible for inclusion were primary research articles related to using assessment tools for the evaluation of arthroscopic skills and training environments. Studies that focussed only on therapeutic cases, did not report outcome measures of technical skills, or did not mention arthroscopic skills training were excluded., Results: A total of 28 studies were included for review. Multiple assessment tools were used in arthroscopic training. The most common objective metric was completion time, reported in 21 studies. Technical parameters based on simulator or external equipment, such as instrument path length, hand movement, visual parameters and injury, were also widely used. Subjective assessment tools included checklists and global rating scales (GRS). Among these, the most commonly used GRS was the Arthroscopic Surgical Skill Evaluation Tool (ASSET). Most of the studies combined objective metrics and subjective assessment scales in the evaluation of arthroscopic skill training., Conclusions: Overall, both subjective and objective assessment tools can be used as feedback for basic arthroscopic skill training, but there are still differences in the frequency of application in different contexts. Despite this, combined use of subjective and objective assessment tools can be applied to more situations and skills and can be the optimal way for assessment., Level of Evidence: Level III, systematic review of level I to III studies. Key messagesBoth subjective and objective assessment tools can be used as feedback for basic arthroscopic skill training.Combined use of subjective and objective assessment tools can be applied to more situations and skills and can be the optimal way for assessment.

Introduction: Wrist arthroscopy has become an essential method in the management of patients suffering from wrist pathologies. This technique must be mastered by residents wishing to specialize in upper limb surgery. However, no study has evaluated residents' access to wrist arthroscopy., Hypothesis: Residents have difficulty accessing wrist arthroscopy surgery during their training., Materials and Methods: We sent out an online questionnaire to all orthopedic and plastic surgery referents in France. Data were collected over a 6-month period from December 2020 to May 2021. A descriptive statistical analysis was performed., Results: Regarding the 98 responses obtained, we observed that 77.54% of residents have seen between 0 and 10 wrist arthroscopies and 35.71% have never seen a wrist arthroscopy. In addition, only 23.80% of residents have had access to training on cadavers, and 57.14% of residents were trained in private facilities., Discussion: Access to the operating room remains difficult for residents in upper limb surgery. Our results suggest that wrist arthroscopy training could be improved. New training methods could be adapted for wrist arthroscopy and to overcome the lack of access to wrist arthroscopy for residents., Level of Incidence: IV., (Copyright © 2022 Elsevier Masson SAS.

Background: The purpose of this study was to utilize the American Board of Orthopaedic Surgery (ABOS) Part-II Case List database to (1) define the practice patterns of sports medicine-trained ABOS Part- II Oral Examination Candidates and (2) describe the frequency and practice patterns of individuals who are dual fellowship-trained sports medicine candidates., Methods: The ABOS Part-II Case List database was utilized to define all cases submitted by 3,298 applicants indicating completion of a sports medicine fellowship between January 1, 2003, and January 1, 2020. Cases were classified by subspecialty category and case type. The frequency and practice patterns of candidates pursuing additional fellowship training (i.e., "dual fellowship-trained") were recorded. Descriptive statistical methods were used to describe the annual and overall procedure volume and candidate case mix. Trends in the relative frequency of cases performed and fellowship training patterns were determined using linear regression analysis., Results: On average, sports medicine-trained candidates submitted 100.6 cases for review during the 6-month case collection period: 59.0 (58.6%) sports medicine/arthroscopy cases, 29.3 (29.1%) trauma/general cases, 4.5 (4.5%) adult reconstruction cases, and 7.8 (7.8%) "other" cases per candidate. Although candidates performed fewer total (r 2 = 0.84, p < 0.001) and sports medicine/arthroscopy (r 2 = 0.85, p < 0.001) cases over the study period, the proportion of sports medicine/arthroscopy cases did not change over the study period (p = 0.18). Dual fellowship training was indicated by 333 individuals (10.1%). The number of dual fellowship-trained candidates pursuing additional fellowship training in pediatrics and adult reconstruction increased over the study period, and the number of dual fellowship-trained candidates pursuing additional fellowship training in trauma decreased over the study period., Conclusions: Early-career sports medicine candidates are likely to perform >40% of cases outside of the sports medicine subspecialty. Sports medicine trainees are increasingly likely to pursue a second fellowship in pediatrics or adult reconstruction., Level of Evidence: Therapeutic Level III .

Background: Women surgeons receive lower compensation, hold fewer academic positions, and hold fewer leadership positions than men, particularly in orthopedic surgery. Gender bias at the trainee level has been demonstrated in various surgical subspecialties, but there is a lack of information on gender bias within the orthopedic training environment. This study investigated whether implicit gender bias is present in the subjective evaluation of orthopedic trainee arthroscopic skills., Methods: After institutional review board approval, a web-based survey was sent to American Shoulder and Elbow Surgeons (ASES) members via the society's email listserve. Study participants were informed that the study was being done to develop a systematic evaluation method for trainees. The survey randomized participants to view and evaluate a prefellowship and a postfellowship video of "Rachel" (she/her) or "Charles" (he/him) performing a 15-point diagnostic shoulder arthroscopy. The videos for Rachel and Charles were identical except for the pronouns used in the video. Participants evaluated the trainee's skill level using questions from the Arthroscopic Surgical Skill Evaluation Tool (ASSET). Blinded and deidentified additional comments regarding the trainee's skill were classified as positive, negative, or neutral. Statistical analyses were used to compare scores and comments between Rachel and Charles., Results: Of 1115 active ASES members, 181 ASES members started the survey and 106 watched both videos and were included in the analysis. Of the 106 participants completing the survey, 96 (91%) were men and 10 (9%) were women with a median (interquartile range) age of 44 (38-51). A teaching role was reported by 84 of 106 participants (79%). There was no significant difference between prefellowship scores (P = .87) or between postfellowship scores (P = .84) for the woman and man fellow. The numbers of comments classified as positive, negative, or neutral were not significantly different between the man and woman fellow (P = .19). Participants in teaching roles gave significantly lower scores to both fellows at both time points (P = .04), and participants who had fellow trainees were more likely to give negative comments to both fellows (P = .02)., Discussion: Trainee gender did not influence the ratings and comments participants gave for trainee arthroscopic skills, suggesting that gender bias may not play a major role in the evaluation of arthroscopic skill during orthopedic training., (Copyright © 2022 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: The aim of this study was to identify if experience in arthroscopy confers ambidexterity to the operator and the role of baseline characteristics in arthroscopic simulator performance., Methods: A prospective comparative study was carried out across four regional Orthopaedic training centres. Participants were divided into novice, intermediate or experienced groups based on arthroscopic experience. Baseline demographics including age, sex, handedness, and gaming history were also collected. Following familiarisation with the procedure, participants were asked to complete a simulated task requiring bimanual control consisting of visualisation with camera control and manipulation of highlighted objects using a grasping instrument. One attempt using camera control and grasping accuracy per hand was performed by each participant, with scores for each hand collected for analysis. Performance scores for camera alignment, camera path length, grasper path length and grasping efficiency were collected. Time taken to completion was also noted for each attempt., Results: Fifty-six participants were recruited to the study. A significant difference in grasping efficiency between groups in the dominant hand was demonstrated (p = 0.013). Novices demonstrated laterality with superior performance in grasping efficiency in the dominant hand (p = 0.001). No significant difference was noted between dominant and non-dominant hand performance in the experienced group., Conclusion: Arthroscopic simulation-based training is a valuable learning tool for orthopaedic training. This study demonstrated that experienced orthopaedic surgeons have a greater degree of ambidexterity than intermediate or novice groups, hypothesised by authors to be conferred through conventional orthopaedic training. Dedicated bimanual control tasks to reduce laterality in trainees should be incorporated in simulated surgical curricula., Level of Evidence: III., (© 2022. The Author(s).)

Purpose: Simulator arthroscopy training has gained popularity in recent years. However, it remains unclear what level of competency surgeons may achieve in what time frame using virtual training. It was hypothesized that 10 h of training would be sufficient to reach the target level defined by experts based on the Diagnostic Arthroscopic Skill Score (DASS)., Methods: The training concept was developed by ten instructors affiliated with the German-speaking Society of Arthroscopy and Joint Surgery (AGA). The programme teaches the basics of performing arthroscopy; the main focus is on learning and practicing manual skills using a simulator. The training was based on a structured programme of exercises designed to help users reach defined learning goals. Initially, camera posture, horizon adjustment and control of the direction of view were taught in a virtual room. Based on these skills, further training was performed with a knee model. The learning progress was assessed by quantifying the exercise time, camera path length and instrument path length for selected tasks. At the end of the course, the learners' performance in diagnostic arthroscopy was evaluated using DASS. Participants were classified as novice or competent based on the number of arthroscopies performed prior to the assessment., Results: Except for one surgeon, 131 orthopaedic residents and surgeons (29 women, 102 men) who participated in the seven courses agreed to anonymous data analysis. Fifty-eight of them were competents with more than ten independently performed arthroscopies, and 73 were novices, with fewer than ten independently performed arthroscopies. There were significant reductions in exercise time, camera path length and instrument path length for all participants after the training, indicating a rapid increase in performance. No difference in camera handling between the dominant and non-dominant sides was found in either group. The competents performed better than the novices in various tasks and achieved significantly better DASS values on the final performance test., Conclusions: Our data have demonstrated that arthroscopic skills can be taught effectively on a simulator, but a 10-h course is not sufficient to reach the target level set by experienced arthroscopists. However, learning progress can be monitored more objectively during simulator training than in the operating room, and simulation may partially replace the current practice of arthroscopic training., Level of Evidence: III., (© 2021.

Background: Virtual reality (VR) simulation is particularly suitable for learning arthroscopy skills. Despite significant research, one drawback often outlined is the difficulty in distinguishing performance levels (Construct Validity) in experienced surgeons. Therefore, it seems adequate to search new methods of performance measurements using probe trajectories instead of commonly used metrics., Hypothesis: It was hypothesized that a larger experience in surgical shoulder arthroscopy would be correlated with better performance on a VR shoulder arthroscopy simulator and that experienced operators would share similar probe trajectories., Materials & Methods: After answering to standardized questionnaires, 104 trajectories from 52 surgeons divided into 2 cohorts (26 intermediates and 26 experts) were recorded on a shoulder arthroscopy simulator. The procedure analysed was the "loose body removal" in a right shoulder joint. 10 metrics were computed on the trajectories including procedure duration, overall path length, economy of motion and smoothness. Additionally, Dynamic Time Warping (DTW) was computed on the trajectories for unsupervised hierarchical clustering of the surgeons., Results: Experts were significantly faster (Median 70.9s Interquartile range [56.4-86.3] vs. 116.1s [82.8-154.2], p<0.01), more fluid (4.6.10 5 mm.s -3 [3.1.10 5 -7.2.10 5 ] vs. 1.5.10 6 mm.s -3 [2.6.10 6 -3.5.10 6 ], p=0.05), and economical in their motion (19.3mm 2 [9.1-25.9] vs. 33.8mm 2 [14.8-50.5], p<0.01), but there was no significant difference in performance for path length (671.4mm [503.8-846.1] vs 694.6mm [467.0-1090.1], p=0.62). The DTW clustering differentiates two expertise related groups of trajectories with performance similarities, respectively including 48 expert trajectories for the first group and 52 intermediates and 4 expert trajectories for the second group (Sensitivity of 92%, Specificity of 100%). Hierarchical clustering with DTW significantly identified expert operators from intermediate operators and found trajectory similarities among 24/26 experts., Conclusion: This study demonstrated the Construct Validity of the VR shoulder arthroscopy simulator within groups of experienced surgeons. With new types of metrics simply based on the simulator's raw trajectories, it was possible to significantly distinguish levels of expertise. We demonstrated that clustering analysis with Dynamic Time Warping was able to reliably discriminate between expert operators and intermediate operators., Clinical Relevance: The results have implications for the future of arthroscopic surgical training or post-graduate accreditation programs using virtual reality simulation., Level of Evidence: III; prospective comparative study., (Copyright © 2021 Elsevier Masson SAS.

Introduction: Procedural training of orthopedic surgery residents includes learning arthroscopic knot-tying. The models used comprise arthroscopy training modules of increasing complexity, although there is no procedural training guide for the acquisition of arthroscopic knot-tying skills. Few studies have focused on how residents learn arthroscopic knot-tying. The aim of our study was to determine the type of arthroscopic knot that is the easiest to perform and learn and that can be done the most successfully by orthopedic surgery residents., Materials and Methods: Each participant had to learn five knots in a random order: Tennessee slider, Duncan loop, Revo knot (Surgeon's knot), Nicky knot, and the SMC (Samsung Medical Center) knot. The FAST Arthroscopy Workstation™ (Sawbones, Vashon Island, WA) was used for this study. Each participant could use a FAST Knot Tester™ (Sawbones®, Vashon Island, WA) to evaluate by themselves the biomechanical properties of the knots to optimize learning. Each participant had to rank how easy it was to learn this knot on a visual scale from 0 to 10. They also had to rank the reliability of the knots done on a visual scale from 0 to 10. Then, an independent rater assessed whether the knots were completed successfully; a knot was considered successful if it stretched by less than 3 mm when 60 N of load was applied., Results: Ten participants were included in the study; 250 knots were done and evaluated. When ranked from simplest to most complicated, the easiest knot to learn was the Surgeon's knot, followed by the Duncan loop, Tennessee slider, Nicky knot and SMC knot (p<0.0001). The overall success rate for the knots was 80%. There was a statistical trend for the Nicky being done better than the other arthroscopic knots (88% success rate)., Conclusion: For orthopedics surgery residents, the surgeon's knot (Revo knot) was the easiest to learn, while the Nicky knot had the highest success rate., Level of Evidence: II; prospective, randomized study with low power., (Copyright © 2021 Elsevier Masson SAS.

Introduction: There are few studies that compare the cadaver dissections with the medical simulators in means of talent improvement. Therefore, the aim of this study is to find out if using cadaver dissections is still the golden standard for surgical training or using the medical simulators in surgery could replace cadaver dissections., Materials and Methods: The study is conducted during the European Orthopaedics & Traumatology Education Platform accredited Shoulder Club International Cadaver Course including a number of 34 orthopedics trainees. The participants were randomly divided into two groups to be trained with the simulator (Group 1) and on cadavers (Group 2), followed by a test performed on shoulder arthroscopy simulator (Virtamed ArthroS, Switzerland). There was no conflict of interest before, during, or after the study. Informed consent was obtained from all individual participants included in the study., Results: Group 2 had statistically significant higher simulation overview procedure time values than Group 1 (p < 0.05), the meaning of which is participants trained with the simulator completed the given tasks in a shorter period of time. Group 2 had statistically significant higher scratching of humerus cartilage values than Group 1 (p < 0.05), which means that participants trained with simulation have less scratching done on the humerus cartilage than the participants trained on a cadaver., Conclusion: To the best of our knowledge, this study is the first one to compare virtual reality (VR) simulators with cadavers for surgical education in an objective manner, while using qualitative and quantitative data. According to this study, it is possible to state that VR simulators are just as effective as cadavers in means of training subjects. As medical education will face a total change all around the world after the COVID-19 pandemic, this study has the potential to be an important guide during and after this period., Competing Interests: There was no conflict of interest before, during, or after the study., (This work is licensed under a Creative Commons Attribution 4.0 International License.)

Background: Arthroscopic simulation has rapidly evolved recently with the introduction of higher-fidelity simulation models, such as virtual reality simulators, which provide trainees an environment to practice skills without causing undue harm to patients. Simulation training also offers a uniform approach to learn surgical skills with immediate feedback. The aim of this article is to review the recent research investigating the use of arthroscopy simulators in training and the teaching of surgical skills., Methods: A systematic review of the Embase, MEDLINE, and Cochrane Library databases for English-language articles published before December 2019 was conducted. The search terms included arthroscopy or arthroscopic in combination with simulation or simulator., Results: We identified a total of 44 relevant studies involving benchtop or virtually simulated ankle, knee, shoulder, and hip arthroscopy environments. The majority of these studies demonstrated construct and transfer validity; considerably fewer studies demonstrated content and face validity., Conclusions: Our review indicates that there is a considerable evidence base regarding the use of arthroscopy simulators for training purposes. Further work should focus on the development of a more uniform simulator training course that can be compared with current intraoperative training in large-scale trials with long-term follow-up at tertiary centers., Competing Interests: Disclosure: The authors indicated that no external funding was received for any aspect of this work.

Background: Competency-based education (CBE) seeks to determine resident proficiency in the knowledge, skills, and behaviors required for independent patient care. Multiple assessment instruments evaluate technical skills or direct patient care in the clinic setting, but there are few reports incorporating both within an orthopedic specialty rotation. This study reports a residency program's comprehensive CBE initiative using formative assessments in the clinic and operating room during a sports medicine rotation., Materials and Methods: The sports medicine rotation used validated formative assessments to evaluate resident performance during clinic encounters and program-defined surgical entrustable professional activities (EPAs). Junior resident (postgraduate year [PGY] 1-2) EPAs included basic knee/shoulder arthroscopic procedures. Senior resident (PYG 5) EPAs comprised anterior cruciate ligament reconstruction, biceps tenodesis, shoulder stabilization, and rotator cuff repair. Assessment scores were compared between individuals and PGY groups., Results: Sixty-six clinical skills (CS) and 106 surgical skills assessments were conducted for 22 residents in one academic year. Surgical skills assessments demonstrated significant differences between each PGY group (P < 0.01). All PGY2 and PGY5 residents achieved independence on the evaluated EPAs. PGY5s earned higher scores in CS assessments than the other classes (P < 0.01). PGY2 residents scored higher than PGY1s in 7 of 9 CS domains. CS independence was achieved by 21 of 22 residents by the end of the rotation., Conclusions: The CBE program effectively quantified expected differences in resident performance by PGY for clinic and surgical assessments on a sports medicine rotation. Assessments built an environment where feedback was more structured and standardized, creating a culture to improve resident education., (Published by Elsevier Inc.)

Purpose: To examine the effect of arthroscopic simulator training on technical performance in a human model., Methods: A systematic review was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Literature searches of PubMed, Embase, and Cochrane Library were conducted using combinations of the terms virtual, digital, computer, reality, simulation, arthroscopy, training, learning, and education. Studies were considered for inclusion if they tested the effect of arthroscopic simulator training in a randomized controlled fashion, performed testing in a cadaver or live patient, and used explicit outcome measures of technical skill. Data from studies were extracted and study characteristics and outcomes were reviewed. The primary outcome measure was the number of studies in which the simulation trained group had significantly improved performance results relative to the control group in ≥50% of all measured outcomes. Risk of bias was assessed with Cochrane's Collaboration Tool., Results: Twelve studies, including 340 total study participants, were included for review. Eight studies showed improved performance of the simulation trained group relative to the control group in ≥50% of assessed outcomes. Six of ten studies reporting completion time, three of six studies reporting task checklist completion, 3 of 7 studies reporting global rating scales, and 1 of 4 studies reporting Arthroscopic Surgical Skill Evaluation Tool scores showed improved performance of the simulation group relative to the control group for the respective outcome measures., Conclusions: The literature is limited due to heterogeneity, both in type and merit, of the outcome measures that have been used to assess the transfer validity of arthroscopic simulator training to clinical performance. Despite the limitations of the literature, this review demonstrates that arthroscopic simulator training has potential to improve clinical performance., Level of Evidence: II, systematic review of Level II studies., (Copyright © 2020 Arthroscopy Association of North America.

Background: Elbow arthroscopy has increased in frequency as its indications have widened. Despite this growth, a learning curve has not yet been defined., Hypothesis: We hypothesized that there would be significant differences in perspective between trainees and established surgeons for the number of cases needed to reach each skill level and what they felt are the most valuable training tools., Methods: Orthopedic attending physicians and trainees were asked to complete a questionnaire assessing participant demographics, case volumes required to reach defined skill levels (novice, safe, competent, proficient, and expert), and the efficacy of various learning methodologies for elbow arthroscopy. The value of educational methods was assessed using a 5-point Likert scale (1 = not at all valuable; 5 = extremely valuable)., Results: The study population consisted of 323 total participants, of whom 224 (69.3%) were attending surgeons and 99 (30.7%) were trainees (resident or fellow physicians). According to the attending physicians, the mean numbers of cases needed to reach each skill level were 19 to be safe, 42 to be competent, 93 to be proficient, and 230 to be expert. These case numbers were not significantly different from the perspectives of trainees. Across the respondents, there were no significant differences in the number of cases needed to reach each level of skill based on the respondents' level of training, years of experience, type of fellowship, or self-reported skill level.Although both groups highly valued live surgery (4.7 of 5) and cadaveric practice (4.6 of 5) for acquiring skill, attendings placed higher value on reading (4.0 vs. 3.3, P < .001), videos/live demos (4.2 vs. 3.6, P < .001), and formal courses (4.5 vs. 4.1, P < .001) than trainees. Both groups place relatively low value on surgical simulators (2.8-3.6)., Conclusions: There was considerable agreement among attending surgeons and trainees in terms of the number of cases needed to attain various skill levels of elbow arthroscopy, which was consistent regardless of fellowship background, self-reported skill level, career length, and elbow arthroscopy case volume. However, there was some disagreement between attending surgeons and trainees over the most valuable methods for acquiring surgical skill with trainees placing less value on textbooks, surgical videos, and formal courses compared with attending surgeons. An understanding of the elbow arthroscopy learning curve will help trainees and their training programs establish case volume targets before safe, independent practice. Future studies should aim to clinically validate this learning curve., (Copyright © 2020 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc. All rights reserved.)

Purpose: To investigate whether acquiring basic knee arthroscopic skills via a spaced retraining schedule could prevent skills deterioration and achieve further skills improvement., Methods: In the learning phase, 16 residents with no previous hands-on experience in practicing arthroscopic skills were asked to perform basic arthroscopic tasks on a simulator until they attained perfect scores in each task. Immediately after completing the learning phase, a pretest was performed to assess their performance. Next, they were randomly assigned into 2 groups. The spaced retraining group, which undertook a spaced repetitive training phase with a fixed-time interval, returned on days 2, 4 and 6 to repeat the same tasks for 20 minutes per day, whereas the control group did nothing. On day 7, all participants performed a posttest. A 2 × 2 mixed analysis of variance model was used for statistical analysis., Results: Significant differences between the 2 groups were found in task completion time (P = .003) and camera path length (P = .043) but not cartilage injury (P = .186). Residents in the spaced retraining group decreased their task completion time (163.2 ± 23.9 seconds) whereas the task time in the control group increased (351.3 ± 25.5 seconds). The same pattern was found with the camera path length., Conclusions: Implementing a spaced retraining schedule in 1 week resulted in a reduced task completion time and camera path length but no significant reduction in cartilage injury. It appears that introducing a spaced retraining schedule to retain arthroscopic skills acquired through massed learning may be advantageous., Clinical Relevance: In consideration of the training time available to residents and the trend toward massed learning, this spaced retraining schedule may offer a cost-effective and convenient way for residents to maintain and improve their basic arthroscopic skills with no significant increase in time invested., (Copyright © 2020 Arthroscopy Association of North America.

Purpose: The European Society for Sports traumatology, Knee surgery and Arthroscopy (ESSKA) identified the need to develop a core curriculum for clinical specialists that work within the interest areas of ESSKA. A research-based approach was used to define a set of core competencies which could be used to map all of their educational activities, resources and development priorities. This paper describes the aims, development, results and implications of this competency-based core curriculum for orthopaedic conditions relevant to ESSKA members., Methods: A Core Curriculum Working Group, with leaders and other experts representing the main specialist areas within ESSKA, reviewed existing curricula and the literature in their own specialist areas. Applying expert group methodology, they iteratively developed a draft list of 285 core competencies for Orthopedic specialists within 6 specialist areas of Knee, Shoulder, Foot/Ankle, Hip, Elbow/Forearm and Sports/Exercise. All ESSKA members were then asked to comment and rate the importance of these competencies, and the Working Group used these findings to critically review and refine the curriculum., Results: The expert groups defined 56 competencies related to 10 Knee pathologies; 67 related to 15 Shoulder pathologies; 45 related to 9 Foot/Ankle pathologies; 41 related to 6 Hip pathologies; and 34 related to 12 Elbow/Forearm pathologies and 42 related to 8 Sports/Exercise pathologies. Survey respondent mean ratings were at least 'Important' for all competencies, and the Working Group used these results to separate the competencies into three levels of importance., Conclusion: A competency-based core curriculum for Orthopedic specialists was achieved through a systematic and scholarly approach, involving both expert opinion and engagement of the wider ESSKA membership, identifying 285 treatment competencies in 6 specialist areas. It is now being used to guide educational and strategic development for ESSKA and should also be of interest to the wider orthopedic and sports medicine communities.

Purpose: To investigate whether resident involvement in knee arthroscopy procedures affects postoperative complications or operative times., Methods: The American College of Surgeons National Surgical Quality Improvement Program registry was queried to identify patients who underwent common knee arthroscopy procedures between 2006 through 2012. Patients with a history of knee arthroplasty, septic arthritis or osteomyelitis of the knee, concomitant open or mini-open procedures, or without information on resident involvement were excluded. A 1:1 propensity score match was performed based on age, sex, obesity, smoking history, and American Society of Anesthesiologist classification to match cases with resident involved to nonresident cases. Fisher exact tests, Pearson's χ 2 tests, and Wilcoxon rank sum tests were used to compare patient demographics, comorbidities, and 30-day complications. Wilcoxon rank sum tests were used to compare operative time and length of hospital stay between the 2 groups, with statistical significance defined as P < .05., Results: After matching, 2954 cases (50% resident involvement) were included in the study with no significant differences in demographics or comorbidities between the 2 cohorts. The overall rate of 30-day complications was 1.1% in the nonresident and resident involved group (P = 1.000). There was no significant difference in postoperative surgical (nonresident vs resident involved: 0.48% vs 0.83%, P = .2498) or medical (nonresident vs resident involved: 0.62% vs 0.83%, P = .5111) complications. However, knee arthroscopy cases that residents were involved with had significantly longer operative times (69.8 vs 66.8 minutes, P = .0002), and length of hospital stay (0.85 vs 0.21 days, P = .0332) when compared with cases performed without a resident., Conclusions: Resident involvement in knee arthroscopy procedures is not a significant risk for medical or surgical 30-day postoperative complications. Resident participation in knee arthroscopy was associated with statistically significant but likely clinically insignificant increased operative time as well as length of hospital stay., Level of Evidence: Level III: Retrospective Cohort Study., (Copyright © 2020 Arthroscopy Association of North America.

Purpose: The purpose of this study is to provide an overview of the published literature on the existing educational methods used to teach surgical skills, with a specific focus on hip surgery, to orthopaedic residents., Methods: A total of 31 articles were selected from a PubMed literature search on the topic of teaching surgical skills to orthopaedic residents, and 9 articles on hip surgery are included in this review., Results: Although several methods are included in the published literature to teach orthopaedic residents, only arthroscopy of the knee and shoulder joint is well described. Hip arthroscopy has a steeper learning curve and thus the use of simulation training as a complementary teaching method is even more important., Conclusions: Currently, open surgery skills for joint arthroplasty are largely acquired by apprenticeship learning. Simulation training in the form of virtual reality could contribute to better performance of residents, decreasing operation time and improving patient safety.

Introduction: Analysis of the Fundamentals of Arthroscopy Surgery Training (FAST) workstation regarding increased proficiency and retention of basic arthroscopy skills in novice subjects., Methods: First-year medical students from a single allopathic medical school performed weekly standardized FAST workstation modules for a consecutive 6 weeks. Primary outcomes evaluated were time to task completion and error rate on specific modules. Scores were analyzed using a one-way repeated measures analysis of variance design for overall trends in time and errors over the 6-week study. Psychomotor retention was analyzed after a 12-week and 24-week interlude., Results: Across the initial 6-week study, the average time to complete all modules at the workstation decreased significantly (P < 0.001) with a mean reduction in the total workstation time of 21.9 minutes (s = 8.12 minutes). Weekly comparisons showed the most significant improvement from week 1 to week 2 for the total workstation time (P < 0.001). Results after a 12-week and 24-week interval of inactivity demonstrated no significant difference in the mean workstation time or errors when compared with the original 6-week study., Discussion: The FAST workstation significantly improved the task performance of novice participants over a 6-week period with no significant deterioration in task performance after 12 and 24 weeks of inactivity.

Background: Arthroscopic surgical simulation, including the use of cadaveric tissue, is valuable for training orthopedic surgery residents. However, it is unclear how often fresh-frozen cadaveric tissue can be reused to provide a reproducible model for developing arthroscopic skills., Objective: We determined the usefulness of ultrasound in evaluating tissue degradation in fresh-frozen shoulder and knee joints used for surgical simulation., Methods: Between February 7 and April 11, 2017, orthopedic residents participated in 6 wet lab sessions during 1 rotation. Knee and shoulder specimens were subjected to ultrasound using a SonoSite Edge machine and a linear probe after each freeze-and-thaw cycle. Degradation of each structure was determined based on standards created for living tissue and comparisons to previous images of the same tissue before initial use., Results: Ultrasonographic assessment of the 2 knee and 2 shoulder specimens revealed lost integrity in subcutaneous fat and muscle with evidence of increased hypoechoicity and loss of normal fiber orientation and density in all specimens examined. Tendons, ligaments, cartilage, iliotibial band, and bone did not lose integrity during freezing and thawing. Ultrasonographic assessment revealed no loss of joint structure integrity. However, the intra-articular work assigned for the simulation curriculum had been carried out to a degree that by the third use, little opportunity remained for further arthroscopic practice on that specimen., Conclusions: In this study, ultrasound findings showed that fresh-frozen shoulder and knee specimens maintained structural integrity useful for simulation training after 3 cycles of freezing., Competing Interests: Conflict of interest: The authors declare they have no competing interests., (Accreditation Council for Graduate Medical Education 2020.)

Introduction: Decreases in trainees' working hours, coupled with evidence of worse outcomes when hip arthroscopies are performed by inexperienced surgeons, mandate an additional means of training. Though virtual reality simulation has been adopted by other surgical specialities, its slow uptake in arthroscopic training is due to a lack of evidence as to its benefits. These benefits can be demonstrated through learning curves associated with simulator training-with practice reflecting increases in validated performance metrics., Methods: Twenty-five medical students with no previous experience of hip arthroscopy completed seven weekly simulated arthroscopies of a healthy virtual hip joint using a 70° arthroscope in the supine position. Twelve targets were visualised within the central compartment, six via the anterior portal, three via the anterolateral portal and three via the posterolateral portal. Task duration, number of collisions (bone and soft-tissue), and distance travelled by arthroscope were measured by the simulator for every session of each student., Results: Learning curves were demonstrated by the students, with improvements in time taken, number of collisions (bone and soft-tissue), collision length and efficiency of movement (all p < 0.01). Improvements in time taken, efficiency of movement and number of collisions with soft-tissue were first seen in session 3 and improvements in all other parameters were seen in session 4. No differences were found after session 5 for time taken and length of soft-tissue collision. No differences in number of collisions (bone and soft-tissue), length of collisions with bone, and efficiency of movement were found after session 6., Conclusions: The results of this study demonstrate learning curves for a hip arthroscopy simulator, with significant improvements seen after three sessions. All performance metrics were found to improved, demonstrating sufficient visuo-haptic consistency within the virtual environment, enabling individuals to develop basic arthroscopic skills.

Purpose: To quantify the effect of the learning curve in performing hip arthroscopy for femoroacetabular impingement (FAI) and labral tears on total operating room time, including times for setup, surgery, and wake up, during a single surgeon's initial hip arthroscopy procedures., Methods: A single surgeon's case list was retrospectively reviewed to identify all primary hip arthroscopy surgeries between November 1, 2018, and February 28, 2018, for the treatment of FAI and labral tears. Surgical times were recorded, including total room time; surgical time; setup time; and wake-up time. Linear regression was used to evaluate the relationship of these times relative to case number in the series. In addition, the series was divided into 3 sequential groups to further compare these times., Results: In total, 225 patients were included in the study. The mean total room time for all cases was 155.4 minutes, 95% confidence interval ([CI] 150.9-160.0); mean surgical time was 115.6 minutes (95% CI 111.5-119.8), and mean setup time was 32.6 minutes (95% CI 31.8-33.4). Decreasing surgical time was associated with advancing number in the case series (P < .001, R 2  = 0.36). Decreasing total room time was accordingly associated with advancing number in the case series (P < .001, R 2  = 0.34). There were no significant differences in setup time and wake-up time as the case series advanced. When groups of 75 sequential cases were compared, significant decreases in surgical and total room time were noted between the first and second groups (P < .001) but not between the second and third groups (P = .52). Increasing complexity of surgeries was noted as the series advanced, including capsular closure and subspine decompression., Conclusions: This study supports the existence of a substantial learning curve for hip arthroscopy in the treatment of FAI and labral tears. Our findings suggest decreasing surgical time as the surgeon advances through the learning curve, with the initial 75 procedures requiring longer time to perform than subsequent cases., Clinical Relevance: Hip arthroscopy is a technically demanding procedure. Understanding the long duration of the hip arthroscopy learning curve is helpful for surgeons considering the addition of hip arthroscopy to their practice., (Copyright © 2019 Arthroscopy Association of North America.

Purpose: To evaluate whether sufficient validity and reliability evidence exists to support the use of global rating scales (GRS) as evaluation tools in both formative assessment and competency assessment of arthroscopic procedures., Methods: A search of PubMed, Embase, and Scopus was conducted for articles published between 1990 and 2018. Studies reporting measures of validity and reliability of GRS relating to arthroscopic skills were included. Procedural checklists and other assessment tools were excluded., Results: A total of 39 articles met the inclusion criteria. In total, 7 de novo GRS specific for arthroscopic education and 3 pre-existing GRS repurposed 4 times for arthroscopic education were identified in the literature. The 11 GRS were used to assess 1175 surgeons 3890 times. Three GRS tools explicitly defined an arbitrary minimum competency threshold, 6 of 11 tools demonstrated construct validity-the ability to significantly discriminate between groups of differing experience-and 5 of 11 tools assessed inter-rater reliability, but only the Arthroscopic Surgical Skills Evaluation Tool demonstrated excellent inter-rater reliability. The Arthroscopic Surgical Skills Evaluation Tool was validated by 16 articles for a total of 537 surgeons for hip, knee, shoulder, and ankle arthroscopy in both simulated and clinical environments but was found to be invalid in wrist arthroscopy. The Basic Arthroscopic Knee Skill Scoring System was validated by 15 articles for a total of 497 surgeons for knee, hip, and shoulder in both clinical and simulated environments. The remaining 9 GRS were validated by 2 or fewer studies., Conclusions: Overall, GRS have contributed to training, feedback, and formative assessment practices. The GRS reviewed demonstrate both construct and concurrent validity as well as reliability in multiple arthroscopic procedures in multiple joints. Currently, there is sufficient evidence to use GRS as a feedback tool. However, there is insufficient evidence for its use in high-stakes examinations or as a minimum competency assessment., Level of Evidence: Level III, systematic review of level I to III studies., (Copyright © 2019 Arthroscopy Association of North America.

Background: The open Latarjet procedure is a standard surgical treatment option for anterior shoulder instability in patients with a high risk of failure following soft tissue stabilization. The arthroscopic technique has potential advantages of minimal invasiveness, reduced postoperative stiffness, and faster rehabilitation but is regarded as technically challenging with concern over surgical risk during the learning curve. The aim of this study was to undertake a multisurgeon, large-volume learning curve analysis of the arthroscopic Latarjet procedure using continuous learning curve analysis., Methods: Individual patient data from 12 surgeons across 5 countries were retrospectively reviewed. A total of 573 patients undergoing the arthroscopic Latarjet procedure were included. Outcome measures of learning were collected, including operative time, computed tomography (CT) bone-block positioning, complications, and patient-reported outcome measures (PROMs). A segmented linear regression modeling technique was used for learning curve analysis., Results: High-volume surgeons converged to an operative time steady state after 30-50 cases. Surgeons completing fewer procedures demonstrated a constant reduction in operative time without reaching a plateau. Low-volume surgeons completing fewer than 14 operations did not demonstrate a reduction in operative time. Accuracy of bone-block positioning on postoperative CT demonstrated constant improvement without reaching a plateau after 53 cases. There was no change in PROMs or complications with increased operative volume., Conclusion: Specialist shoulder surgeons require 30-50 arthroscopic Latarjet procedures to attain steady-state operative efficiency, during which there is improvement in bone-block positioning. Only surgeons expecting to undertake the arthroscopic Latarjet in high volume should consider adopting this procedure., (Copyright © 2019 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: The purpose of this study was to compare the clinical practices between expert and non-expert arthroscopy hip surgeons., Methods: Registered orthopedic surgeons completed anonymous surveys during a hip arthroscopy meeting. The survey included 60 questions on physician's level of expertise, surgical anesthesia, procedures performed, hospital stay, pain control, rehabilitation and socioeconomic parameters, and the results are presented. Comparisons were made between hip arthroscopy experts (> 500 cases performed) and non-experts (≤ 500 cases performed) on aspects of patient care., Results: Forty-eight (74%) surgeons responded. Forty-four questionnaires were filled out completely. There were no significant differences in recommendations between 15 (34%) hip arthroscopy experts and 29 (66%) non-experts on hip capsular management and cartilage repair techniques, use of antithrombotic prophylaxis and opioid analgesics, time of rehabilitation initiation and patient compliance factors, use of hip brace and CPM, and patient evaluation to return to sports following surgery. Surgical expertise was significantly associated with the performance of hip labral reconstruction (p = 0.016), subspine decompression (p = 0.039) and recommendation of a longer period of restricted weight bearing following the performance of microfractures (p = 0.011). There were no significant differences in clinical practice between surgeons who performed hip arthroscopy exclusively versus those who did not., Conclusions: Hip arthroscopy is a relatively new field, and clinical practice may vary among physicians based on the surgical expertise. In this study, hip arthroscopy experts agree with non-experts on most aspects of patient care. Surgical expertise was associated with performance of advanced techniques and recommendation of longer period of restricted weight bearing following performance of microfractures. This study highlights different care patterns that need to be investigated to determine which treatment results in improved patient care., Level of Evidence: V.

This cadaveric study assessed factors that could lead to nonunions in subtalar joint arthrodesis. The purpose of this study was to assist surgeons in achieving sufficient joint preparation in hopes to achieve more frequent arthrodesis of the subtalar joint. We evaluated the influence of experience in regard to cartilage preparation of the joint. We also assessed which quadrants of the subtalar joint were more likely to have unprepared cartilage. The subtalar joints in 17 cadaveric limbs were prepared by 17 participants with differing levels of experience. After the cartilage was denuded, the percentage of unprepared cartilage in each subtalar joint was calculated. The medial quadrants were more likely to have unprepared surfaces. There was also a learning curve present with subtalar joint preparation, as seen by the significantly larger percentage of unprepared cartilage in cadavers prepared by first year residents., (Copyright © 2019 the American College of Foot and Ankle Surgeons.

Purpose: The aim of this work is to evaluate the effectiveness of training with the low-fidelity ArthroBox ® regarding performance of different basic arthroscopy tasks using a validated high-fidelity virtual reality simulator of the knee., Methods: Nineteen volunteers (14 females and 5 males) without any previous experience in arthroscopy were randomly assigned either to the ArthroBox ® training group (n =10) or the non-training group (n =9). The training group underwent a supervised ArthroBox ® training consisting of a daily 60-min session for three consecutive days. Both groups completed the basic and the final assessment using a validated virtual reality-based passive haptic knee arthroscopy simulator (ArthroS, VirtaMed™). The following three factors were measured in different exercises (explained in "Materials and methods"): amount of time to finish the task, length of camera and scope path within the joint. Furthermore, the volunteers' demographics (age, sex, dexterity, video game experience, sport activities and profession) was assessed but showed no differences between the groups., Results: There were no significant differences between the training and non-training group regarding the above-mentioned demographic factors. However, the training group showed significant improvement from baseline to follow-up in most activities (e.g. task performance time in seconds, intra-articular camera and grasp distance in centimetres; see Table 1) in comparison to the non-training group., Conclusions: The results from this study demonstrate that training for three consecutive days using a portable and versatile low-fidelity simulator significantly improves arthroscopy performance when using a validated high-fidelity virtual knee simulator. Arthroscopic triangulation training outside the operating theatre with a portable, low-cost simulator has proven to be a valuable educational tool to improve the arthroscopic skills of trainee surgeons., Level of Evidence: Diagnostic study, Level II.

Introduction: Surgeons are required to have a sound knowledge regarding all operating theatre equipment they wish to use. This is important to ensure patient safety and theatre efficiency. Arthroscopy forms a significant part of all orthopaedic subspecialty practice. Proficiency in performing arthroscopic procedures is assessed during registrar training. The aim of this survey was to determine the competence of orthopaedic trainee registrars in setting up the arthroscopy stack system and managing intraoperative problems., Materials and Methods: Electronic survey forms were sent to all orthopaedic training programme directors in the UK to be forwarded to trainees in their deanery. The electronic survey contained 13 questions aimed at determining trainee experience and competence level with working with the arthroscopy stack system., Results: A total of 138 responses were received from 14 deaneries in the UK. Almost all registrars had experienced intraoperative delays because of equipment malfunction that required addressing by more competent staff. However, 82% of respondents had not received any formal training for operating the arthroscopy stack system. Some 82% of registrars of ST7 grade or above, who had performed over 50 arthroscopic procedures and achieved a level 4 PBA competence, were unable to set up the stack system and successfully address these delays., Conclusions: Inadequate training is delivered to orthopaedic registrars from both the training programme and arthroscopy-themed courses with regards to set-up and operation of the arthroscopy tower system. This training should be part of the curriculum to ensure patient safety and efficient theatre practice.

Background: There is increasing emphasis on assessing resident competency, but little has been published on how to best evaluate trainee competency for ankle arthroscopy. The purpose of this study was to validate an objective model for assessing basic ankle arthroscopy knowledge and operative skills on a cadaveric ankle., Methods: The Diagnostic Ankle Arthroscopy Skills Scoring System was adapted from previously validated assessment tools for knee arthroscopy. The scoring system included (1) an oral questionnaire (0-23 points), (2) an operative task-specific checklist (0-19 points), and (3) a global operative skills rating (12-60 points). Thirty-three trainees consisting of orthopedic residents and medical students performed a diagnostic ankle arthroscopy on a cadaveric ankle and were assessed by a single observer, while a subset were tested by 2 evaluators to determine interobserver reliability., Results: There was strong correlation between educational level and scores on the global operative skills rating scale ( r = 0.967, P < .0001), task-specific checklist ( r = 0.815, P < .815), and oral questionnaire ( r = 0.896, P < .0001). The global operative skills scores significantly improved with training level, and the largest difference was between medical students and senior residents. The most notable year-to-year increases in skill were between postgraduate year (PGY) 1 and 2 ( P < .01) and between PGY2 and PGY3 ( P < .05). Oral questionnaire and task-specific checklists were significantly lower for medical students than PGY1 residents ( P < .001). There was also significant improvement in the oral questionnaire between senior and junior residents ( P < .05). There was a moderate correlation between number of self-reported ankle arthroscopy cases and scores on the global operative skills score ( r = 0.7019, P < .0001). Interobserver reliability was high for the global operative skills scores (interclass correlation coefficient = 0.89)., Conclusion: The study revealed a valid measure to objectively assess trainees' ankle arthroscopy clinical knowledge and operative skills in a bioskills laboratory., Clinical Relevance: This tool should enable residency programs to evaluate competency and track individual trainee progress over time.

Purpose: To assess the effectiveness of cadaveric ankle arthroscopy courses in reducing iatrogenic injuries., Methods: A total of 60 novice surgeons enrolled in a basic cadaveric ankle arthroscopy course were divided into two groups. Group A (n = 32) was lectured on portal placement and use of the arthroscope, whereas group B (n = 28) was in addition lectured on specific portal-related complications. Following the performance of anterior ankle arthroscopy and hindfoot endoscopy, the specimens were dissected and carefully assessed for detection of any iatrogenic injuries., Results: The rate of injury to the superficial peroneal nerve (SPN) was reduced from 25 to 3.6%, in group A compared with B (p = 0.033). Injuries to the peroneus tertius or extensor digitorum longus, the flexor hallucis longus and the tibial nerve or the Achilles tendon were also reduced in group B. Overall, the number of uninjured specimens was 50% (n = 30) and higher in group B (57%) than group A (44%). Lesions to the plantaris tendon, the sural nerve or the posterior tibial artery were more common in group B, however, without reaching statistical significance. Overall, 25 (13.9%) anatomic structures were injured in anterior arthroscopy compared to 18 (5%) in hindfoot endoscopy, out of a potential total of 180 and 360, respectively (p = 0.001)., Conclusion: Dedicated lectures on portal-related complications have proven useful in reducing the risk of injury to the SPN, the commonest iatrogenic injury encountered in ankle arthroscopy. Hindfoot endoscopy is significantly safer than anterior ankle arthroscopy in terms of injury to anatomical structures.

Background: Arthroscopy simulators offer safe and reproducible training to orthopaedic residents, thereby obviating the need for cadaver specimens. In addition, they collect data that can serve to investigate learning curves and evaluate training programmes with the goal of improving the quality of arthroscopy teaching. In this study, a cohort of surgeons was evaluated before and after a European theoretical and practical training programme that used a knee arthroscopy simulator. The primary objective was to assess whether the overall performance score was improved by the training programme. The secondary objectives were to determine which tasks and skills were improved by the programme, to compare a novice group to an experienced group, and to identify targets for improvement., Hypothesis: A theoretical and practical training course improves the scores achieved on an arthroscopy simulator task., Methods: A prospective comparative study was performed in 34 surgeons during the advanced arthroscopy training course organised by the European Paediatric Orthopaedic Society (EPOS) in January 2018. All participants performed a diagnostic task on the VirtaMed ArthroS™ simulator before and after the programme. The participants were divided into two groups based on number of knee arthroscopies performed each year, i.e.,>20 (experienced group) vs.≤20 (inexperienced group). The following parameters were compared between the two groups: overall score, operative time, percentage of iatrogenic injuries, camera and hook path lengths, and success in identifying anatomical structures., Results: The overall score on the diagnostic task was 199 before and 203 after the training programme (p=0.02). The operative time decreased significantly, from 185 to 115.9seconds (p<0.01). Camera path length decreased from 85.2 to 49.2cm and hook path length from 65.5 to 15.0cm (p<0.05). The mean proportion of arthroscopies with iatrogenic tibial cartilage injuries diminished from 2.7%±1.7% (range, 0-6.7) to 1.8%±1.8% (range, 0-7) (p=0.03); no change occurred in femoral injuries. When each group was assessed separately, the only significant change found in the experienced group was a decrease in operative time, whereas in the inexperienced group all parameters improved significantly. However, visualisation of anatomical structures was unchanged., Conclusion: Participation in the training programme improved overall performance, and the gains were greatest in the inexperienced group. During the post-training evaluation, some of the major anatomical structures were classified by the simulator as incompletely visualised, raising concern about a risk of underdiagnosis during arthroscopic explorations., Level of Evidence: III, prospective comparative study., (Copyright © 2019 Elsevier Masson SAS.

Background: Arthroscopic surgery is a steadily expanding component of orthopaedic practice that changes continuously as new techniques and indications develop. The many arthroscopy training activities offered to residents include fellowships, practice on cadaver specimens and simulators, and teaching in the operating room. Current practices for arthroscopy training of orthopaedic residents in France have not yet been evaluated. The objectives of this study were to describe current arthroscopy training practices and to assess the perceptions and expectations of residents and junior physicians in France, in order to contribute to the development of a new training strategy for residents., Hypothesis: Residents and junior physicians perceive gaps in their arthroscopy training., Methods: Between November 2018 and February 2019, the Junior French Arthroscopy Society (Société Francophone d'Arthroscopie Junior, SFAJ) conducted a descriptive epidemiological survey of 918 residents, clinical fellows, and junior physicians in orthopaedic surgery departments in France. The data were collected via an online questionnaire sent by e-mail. The questionnaire had items on demographics; perceptions of, and expectations about, arthroscopy skills training during the residency; and experience in performing arthroscopic procedures., Results: Of the 918 residents, 106 responded to the questionnaire. Most respondents were near the end of their training: 26 (24.8%) were 4th-year residents, 23 (21.6%) were 5th-year residents, 15 (14.3%) were clinical fellows, and 13 (12.4%) were junior physicians. Among respondents, 42 (40%) had performed fewer than 5 simple arthroscopy procedures as the main operator and 73 (69.5%) felt they were not, or would not be, capable of performing arthroscopic procedures without supervision by the end of their residency., Conclusion: The survey findings highlighted the challenges encountered by French orthopaedics residents in acquiring satisfactory arthroscopy skills during their residency. They also suggested avenues for improvement such as simulator training or the development of training on cadaver specimens., Level of Evidence: IV, descriptive survey., (Copyright © 2019 Elsevier Masson SAS.
