Due to the physicality of the game, players are at a higher risk of injury. In the 2010 Winter Olympics, men’s ice hockey had the highest injury rate compared to any other sport. In this review, we present a comprehensive analysis of evaluation and management strategies of common hand, wrist, and elbow injuries in ice hockey players. Future reseach focusing on the incidence and outcomes of these hand, wrist and elbow injuries in ice hockey players is warranted.Keywords: ice hockey, dorsal ulnotriquetral ligament, olecranon bursitis, Os styloideum, gamekeeper’s thumb

Given the operatively challenging nature of these procedures, there lies a potentially increased risk of postoperative complications and healthcare expenditures. Our investigation sought to identify patient and surgical risk factors associated with prolonged hospital stays following isolated PCL reconstruction and determine the incidence of 30-day complications after PCL reconstruction using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.Method: Patients undergoing isolated PCL reconstructions between 2005 and 2016 were identified in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database using Current Procedural Terminology codes. Baseline patient and operative characteristics were evaluated as possible risk factors for overnight hospital admissions following PCL reconstruction and analyzed using multivariate analyses.Results: A total of 249 patients were identified. Multivariate analyses demonstrated that increased operative duration >120 mins (OR 5.04, CI 2.44–10.40; p 120 mins carried an increased risk of overnight hospital stay after isolated PCL reconstructions. As there are presently minimal significant clinical differences between current PCL reconstruction techniques, improved surgeon familiarity and comfort with a single technique is recommended to decrease operative time and avoid prolonged hospital stays and healthcare expenditures.Level of evidence: III, retrospective comparative study.Keywords: operative time, overnight hospital stays, healthcare expenditures, American College of Surgeons National Surgical Quality Improvement Program, NSQIP

Background: In 2020, the American Society of Shoulder and Elbow Therapists (ASSET) published an evidence-based consensus statement outlining postoperative rehabilitation guidelines following anatomic total shoulder arthroplasty (TSA)., Purpose: The purpose of this study was to (1) quantify the variability in online anatomic TSA rehabilitation protocols, and (2) assess their congruence with the ASSET consensus guidelines., Methods: This study was a cross-sectional investigation of publicly available, online rehabilitation protocols for anatomic TSA. A web-based search was conducted in April 2022 of publicly available rehabilitation protocols for TSA. Each collected protocol was independently reviewed by two authors to identify recommendations regarding immobilization, initiation, and progression of passive (PROM) and active range of motion (AROM), as well as the initiation and progression of strengthening and post-operative exercises and activities. The time to initiation of various components of rehabilitation was recorded as the time at which the activity or motion threshold was permitted by the protocol. Comparisons between ASSET start dates and mean start dates from included protocols were performed., Results: Of the 191 academic institutions included, 46 (24.08%) had publicly available protocols online, and a total of 91 unique protocols were included in the final analysis. There were large variations seen among included protocols for the duration and type of immobilization post-operatively, as well as for the initiation of early stretching, PROM, AROM, resistance exercises, and return to sport. Of the 37 recommendations reported by both the ASSET and included protocols, 31 (83.78%) were found to be significantly different between groups (p\<0.05)., Conclusion: Considerable variability was found among online post-operative protocols for TSA with substantial deviation from the ASSET guidelines. These findings highlight the lack of standardization in rehabilitation protocols following anatomic TSA., Level of Evidence: 3b., Competing Interests: There are no financial biases or conflicts of interest for any author related to this study. The study was exempt from International Review Board approval as no identifiable patient information was used., (© The Author(s).)

Purpose: To systematically review the literature regarding the biomechanical properties of different repair techniques and fixation methods for vertically oriented meniscal tears., Methods: Human cadaveric studies evaluating the biomechanical properties of different repair techniques for vertically oriented meniscal tears were identified using the PubMed, EMBASE, and Cumulative Index to Nursing & Allied Health databases. Primary outcomes included load to failure, displacement, stiffness, peak contact pressure, and contact area of repaired menisci. Repair techniques from included studies were reclassified into a total of 19 distinct all-inside (AI), inside-out (IO), or outside-in (OI) techniques., Results: Sixteen studies were included (420 total menisci). Contact pressure and area were restored to intact-state values across all 5 compressive load studies at low knee flexion angles but not at greater knee flexion angles (i.e., >60°). There were no significant differences in contact pressure or area between AI, IO, and OI techniques across all studies. Some studies demonstrated statistically significant advantages in tensile properties with IO techniques when compared with AI techniques, whereas others found AI techniques to be superior. No studies directly compared tensile properties of OI techniques with those of AI or IO techniques. Vertical mattress suture configurations resulted in significantly greater load to failure and decreased displacement compared with horizontal mattress configurations in 67% of studies comparing the 2 techniques. There was no difference in the rate of tissue failure in AI (66.97%), IO (60.38%), or OI (66.67%, χ 2  = 0.83, P = .66) techniques., Conclusions: Contact mechanics are reliably restored after repair of vertical meniscal tears at low flexion angles but inconsistently restored at greater flexion angles, regardless of technique. Vertical mattress configurations outperformed horizontal mattress configurations under tensile load. There are conflicting data regarding the comparison of tensile properties between AI and IO techniques. Ultimately, neither AI, IO, nor OI repair demonstrated superior biomechanical properties in the present literature., Clinical Relevance: Several repair techniques demonstrate favorable biomechanical properties for vertical meniscal tears under tensile and compressive loads. Neither AI, IO, nor OI repair techniques demonstrate superior biomechanical properties at this time., Competing Interests: Disclosures The authors report the following potential conflicts of interest or sources of funding: J.C. reports other from the American Orthopaedic Society for Sports Medicine, AANA, and International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine; personal fees from Arthrex, Conmed Linvatec, Ossur, and Smith & Nephew, outside the submitted work.

Background: Significant psychological impact and prevalence of posttraumatic stress disorder (PTSD) have been well documented in patients sustaining anterior cruciate ligament injury., Purpose: To examine PTSD symptomatology in baseball players after sustaining elbow ulnar collateral ligament (UCL) injury., Study Design: Cross-sectional study; Level of evidence, 3., Methods: Male baseball players of various competition levels (high school through Minor League Baseball [MiLB]) who underwent surgery for a UCL injury between April 2019 and June 2022 participated in the study. Before surgery, patients completed the Impact of Event Scale-Revised (IES-R) to assess PTSD symptomatology. Subgroup analysis was conducted according to level of play and player position., Results: A total of 104 male baseball players with a mean age of 19.4 years (range, 15-29 years) were included in the study; 32 players (30.8%) were in high school, 65 (62.5%) were in college, and 7 (6.7%) were in MiLB. There were 64 (61.5%) pitchers, 18 (17.3%) position players, and 22 (21.2%) 2-way players (both pitching and playing on the field). A total of 30 (28.8%) patients scored high enough on the IES-R to support PTSD as a probable diagnosis, and another 22 patients (21.2%) scored high enough to support PTSD as a clinical concern. Nineteen patients (18.3%) had potentially severe PTSD. Only 4 players (3.8%) were completely asymptomatic. Subgroup analysis revealed college players as significantly more symptomatic than high school players ( P = .02), and 2-way players were found to be significantly less susceptible to developing symptoms of PTSD compared with pitchers ( P = .04)., Conclusion: Nearly 30% of baseball players who sustained a UCL injury qualified for a probable diagnosis of PTSD based on the IES-R. Pitchers and college athletes were at increased risk for PTSD after UCL injury compared with 2-way players and high school athletes, respectively., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: M.J.J.A. has received grant support from DJO, education payments from Smith + Nephew, and hospitality payments from Medical Device Business Services.

Background: Social media has the potential to play a substantial role in the decision-making of patients when choosing a physician for care., Purpose: The purpose of this study was to determine whether an association exists between physician social media activity and patient satisfaction ratings on physician review websites (PRWs) as well as number of reviews. It was hypothesized that there would be a significant association between physician social media utilization and patient satisfaction ratings., Study Design: Cross-sectional study., Methods: The American Orthopaedic Society for Sports Medicine database was queried for the complete membership list. The online media profile and level of activity of the members were evaluated, and an online media presence score was calculated. The surgeons with the approximately top 10% of online media presence scores were compiled to assess the relationship between social media usage (Twitter, Instagram, YouTube, and Facebook) and patient satisfaction ratings on the Google Reviews, Healthgrades, and Vitals PRWs. Bivariate analysis was performed to compare demographic variables and level of online presence., Results: A total of 325 surgeons were included in the analysis. The most common platform used was Facebook (88.3%). There was no significant relationship between active social media use and overall ratings on any of the PRWs. Active Twitter use was associated with a greater number of ratings on all review websites, a greater number of comments on Google Reviews and Healthgrades, and shorter patient-reported clinic wait times on Healthgrades. Active Instagram use was associated with a greater number of comments on Vitals. No relationships were observed for YouTube or Facebook., Conclusion: For the included sports medicine surgeons who were most active on social media, no significant relationships were found between social media use and overall ratings on PRWs. Of all the platforms assessed, active use of Twitter was the only significant predictor of more reviews on PRWs. Thus, when deciding which form of social media engagement to prioritize in building one's practice, Twitter may serve as a relatively low-demand, high-reward option., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: H.W.S. has received education payments from Medwest Associates and Smith & Nephew.

Purpose: To report the mid-term outcomes of patients who underwent revision meniscal allograft transplantation (RMAT) and compare survivorship free from reoperation and failure with a matched cohort of patients who underwent primary meniscal allograft transplantation (PMAT)., Methods: A retrospective review of prospectively collected data identified patients who underwent RMAT and PMAT between 1999 and 2017. A cohort of PMAT patients matched at a ratio of 2:1 with respect to age, body mass index, sex, and concomitant procedures served as the control group. Patient-reported outcome measures (PROMs) at baseline and at a minimum of 5 years postoperatively were collected. PROMs and the achievement of clinically significant outcomes were analyzed within groups. Graft survivorship free from meniscal reoperation and failure (arthroplasty or subsequent RMAT) was compared between cohorts using log-rank testing., Results: During the study period, 22 RMATs were performed in 22 patients. Of these RMAT patients, 16 met the inclusion criteria (73% follow-up rate). The mean age of RMAT patients was 29.7 ± 9.3 years, and the mean follow-up period was 9.9 ± 4.2 years (range, 5.4-16.8 years). There were no differences between the RMAT cohort and the 32 matched PMAT patients with respect to age (P = .292), body mass index (P = .623), sex (P = .537), concomitant procedures (P ≥ .286), or baseline PROMs (P ≥ .066). The patient acceptable symptomatic state was achieved by the RMAT cohort for the subjective International Knee Documentation Committee score (70%), Lysholm score (38%), and Knee Injury and Osteoarthritis Outcome Score subscales (Pain [73%], Symptoms [64%], Sport [45%], Activities of Daily Living [55%], and Quality of Life [36%]). In the RMAT cohort, 5 patients (31%) underwent subsequent reoperation at a mean of 4.7 ± 2.1 years (range, 1.7-6.7 years) and 5 patients met the criteria for failure at a mean of 4.9 ± 2.9 years (range, 1.2-8.4 years). There were no significant differences in survivorship free from reoperation (P = .735) or failure (P = .170) between the RMAT and PMAT cohorts., Conclusions: At mid-term follow-up, most patients who underwent RMAT achieved the patient acceptable symptomatic state for the subjective International Knee Documentation Committee score and the Knee Injury and Osteoarthritis Outcome Score subscales of Pain, Symptoms, and Activities of Daily Living. Additionally, there were no differences in survival free from meniscal reoperation or failure between the PMAT and RMAT cohorts., Level of Evidence: Level III, retrospective comparative cohort., (Copyright © 2023 Arthroscopy Association of North America.

Background: Posterior cruciate ligament (PCL) reconstruction techniques have historically focused on single-bundle (SB) reconstruction of the larger anterolateral bundle without addressing the codominant posteromedial bundle. The SB technique has been associated with residual laxity and instability, leading to the development of double-bundle (DB) reconstruction techniques., Purpose: To perform a meta-analysis of comparative clinical and biomechanical studies to differentiate the pooled outcomes of SB and DB PCL reconstruction cohorts., Study Design: Meta-analysis and systematic review: Level of evidence, 3., Methods: Six databases were queried in February 2022 for literature directly comparing clinical and biomechanical outcomes for patients or cadaveric specimens undergoing DB PCL reconstruction against SB PCL reconstruction. Biomechanical outcomes included posterior tibial translational laxity, external rotational laxity, and varus laxity at 30° and 90° of knee flexion. Clinical outcomes included the side-to-side difference in posterior tibial translation during postoperative stress radiographs, risk of a major complication, and the following postoperative patient-reported outcome measures: Lysholm, Tegner, and International Knee Documentation Committee (IKDC) subjective and objective scores. A random-effects model was used to compare pooled clinical and biomechanical outcomes between the cohorts., Results: Fifteen biomechanical studies and 13 clinical studies were included in this meta-analysis. The DB group demonstrated significantly less posterior tibial translation at 30° and 90° of knee flexion ( P < .00001). Additionally, the DB group demonstrated significantly less external rotation laxity at 90° of knee flexion ( P = .0002) but not at 30° of knee flexion ( P = .33). There was no difference in varus laxity between the groups at 30° ( P = .56) or 90° ( P = .24) of knee flexion. There was significantly less translation on stress radiographs in the DB group ( P = .02). Clinically, there was no significant difference between the groups for the Lysholm score ( P = .95), Tegner score ( P = .14), or risk of a major complication ( P = .93). DB PCL reconstruction led to significantly higher odds of achieving "normal" or "near normal" objective IKDC outcomes for the included prospective studies ( P = .04) and higher subjective IKDC scores ( P = .01)., Conclusion: DB PCL reconstruction leads to superior biomechanical outcomes and clinical outcomes relative to SB PCL reconstruction. Re-creating native anatomy during PCL reconstruction maximizes biomechanical stability and clinical outcomes., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: H.W.S. has received support for education from Smith & Nephew and Medwest Associates.

Background: Patients are faced with several treatment decisions after an ulnar collateral ligament (UCL) injury: nonoperative versus operative treatment, repair versus reconstruction, and immediate versus delayed surgery., Purpose/hypothesis: The aim of this study was to investigate the factors important to patients when deciding which treatment to pursue after a UCL injury. We hypothesized that (1) length of time away from sports and seasonal timing would be important to patients and (2) treatment decision-making would be heavily influenced by how many and which seasons of their baseball career would be missed., Study Design: Cross-sectional study., Methods: High school and collegiate baseball players with UCL tears treated at an academic institution were surveyed retrospectively on their sports participation at the time of injury and their UCL injury treatment decisions. Respondents rated the influence of various factors on a 5-point Likert scale, and they selected the top 3 factors and the single most important factor influencing their treatment decisions. Multiple logistic regression analysis was used to assess the relationship between player characteristics and factors important to their treatment decision., Results: A total of 83 athletes completed the survey; 40 were in high school and 43 were in college at the time of injury; 7 were treated nonoperatively and 76 underwent surgery (66 immediately and 10 in a delayed fashion), 10 with UCL repair and 66 with UCL reconstruction. The ability to play competitive baseball in the long term was very important or extremely important to 90% of players, while the ability to play in the short term was very important or extremely important to 17%. Length of recovery and seasonal timing were also important factors for 53% and 54% of players, respectively, and almost all (90%) highly valued advice from a surgeon. Possible failure of nonoperative treatment leading to increased time away and the possible loss of 2 consecutive baseball seasons heavily influenced decision-making in 41% of respondents., Conclusion: Survey respondents were driven by the desire to play baseball in the long term. Treatment decisions were influenced by the length of recovery and by the seasonal timing of their injury, both of which affect how many and which seasons of baseball a player may miss. Patients found advice from their surgeon to be extremely important to decision-making., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: H.W.S. has received education payments from Medwest and Smith & Nephew.

Background: Textbook knowledge and clinical dogma are often insufficient for effective evidence-based decision making when treating musculoskeletal injuries in American football players, given the variability in presentation and outcomes across different sports and different levels of competition. Key evidence can be drawn directly from high-quality published articles to make the appropriate decisions and recommendations for each athlete's unique situation., Purpose: To identify and analyze the 50 most cited articles related to football-related musculoskeletal injury to provide an efficient tool in the arsenal of trainees, researchers, and evidence-based practitioners alike., Study Design: Cross-sectional study., Methods: The ISI Web of Science and SCOPUS databases were queried for articles pertaining to musculoskeletal injury in American football. For each of the top 50 most cited articles, bibliometric elements were evaluated: citation count and density, decade of publication, journal, country, multiple publications by the same first author or senior author, article content (topic, injury area), and level of evidence (LOE)., Results: The mean ± SD number of citations was 102.76 ± 37.11; the most cited article, with 227 citations, was "Syndesmotic Ankle Sprains" published in 1991 by Boytim et al. Several authors served as a first or senior author on >1 publication, including J.S. Torg (n = 6), J.P. Bradley (n = 4), and J.W. Powell (n = 4). The American Journal of Sports Medicine published the majority of the 50 most cited articles (n = 31). A total of 29 articles discussed lower extremity injuries, while only 4 discussed upper extremity injuries. The majority of the articles (n = 28) had an LOE of 4, with only 1 article having an LOE of 1. The articles with an LOE of 3 had the highest mean citation number (133.67 ± 55.23; F = 4.02; P = .05)., Conclusion: The results of this study highlight the need for more prospective research surrounding the management of football-related injury. The low overall number of articles on upper extremity injury (n = 4) also highlights an area for further research., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: H.W.S. has received education payments from Medwest and Smith & Nephew.

Purpose: To develop a magnetic resonance imaging (MRI)-based classification system integrating tear characteristics including tear thickness (partial vs full) and tear retraction (less than or greater than 2 cm) for gluteus medius and/or minimus tears and to determine the inter-rater reliability of this MRI-based classification for gluteus medius and/or minimus tears., Methods: Patients who underwent primary endoscopic or open repair of gluteus medius and/or minimus tears between 2012 and 2022 were identified to be included in the review of 1.5-T MRI scans. One hundred MRI scans were randomized for review by 2 orthopaedic surgeons and evaluated for tear thickness (partial vs full), extent of retraction, and degree of fatty infiltration according to an applied Goutallier-Fuchs (G-F) classification. Tears were also graded according to the 3-grade MRI-based classification system as follows: grade 1, partial-thickness tears; grade 2, full-thickness tears with less than 2 cm of retraction; grade 3, full thickness with 2 cm or more retraction. Inter-rater reliability was calculated by absolute and relative agreement using Cohen's kappa (κ). Significance was defined by P value <.05., Results: In total, 221 patients were identified, and after application of exclusion criteria and randomization, 100 scans were evaluated. The 3-grade classification system demonstrated high absolute agreement (88%) comparable to the absolute agreement of the G-F classification (67%). The 3-grade classification system demonstrated substantial inter-rater reliability (κ = 0.753), whereas the G-F classification demonstrated moderate inter-rater reliability (κ = 0.489)., Conclusions: The proposed 3-grade MRI-based classification system for gluteus medius and/or minimus tears demonstrated substantial inter-rater reliability, comparable with that of the applied G-F classification., Clinical Relevance: It is important to understand how gluteus medius and/or minimus tear characteristics impact postoperative outcomes. The 3-grade MRI-based classification incorporates tear thickness and amount of retraction that can complement previous classification systems to give the provider and patient more information when considering treatment options., (© 2023 The Authors.)

Background: Social media has the potential to act as an avenue for patient recruitment, patient and surgeon education, and expansion of the physician-patient relationship., Purpose: To evaluate the existing social media presence among members of the American Orthopaedic Society for Sports Medicine (AOSSM) to describe trends in different subgroups within the membership., Study Design: Cross-sectional study., Methods: The AOSSM database was queried for a complete membership list. Members were excluded from analysis if they were not orthopaedic sports medicine surgeons practicing in the United States. Demographic characteristics, online media profiles, and levels of online presence were evaluated, and an online media presence score was calculated. Bivariate analysis was performed to compare demographic variables and levels of online presence., Results: A total of 2870 surgeons were included in the analysis. LinkedIn was the most used platform (56%), while YouTube was the least used (10%). Surgeons in academic practice had a significantly greater overall social media presence than their private practice counterparts. Female surgeons had a more significant active online presence on Twitter, Instagram, and Facebook than male surgeons. Surgeons practicing in the Northeast had a greater social media presence than those in any other United States region, and surgeons in the earlier stages of practice (0-14 years) were more likely to utilize social media than their more senior colleagues (≥15 years of practice). On multivariate analysis, surgeons in the earlier stages of practice were more likely to have active Twitter, Instagram, and Facebook accounts, and female surgeons were more likely to have an active Facebook account. Additionally, multivariate analysis revealed that a greater number of ResearchGate publications were associated with male sex and having an academic practice. Comparatively, active Twitter and Instagram use was associated with having an academic practice., Conclusion: The most used platform in this surgeon population was LinkedIn. Orthopaedic surgeons in academic practice, female surgeons, those early in their career, and those practicing in the Northeast highlighted a subset of the sports medicine community who were more likely to have an active online presence compared to the rest of the AOSSM., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: H.W.S. has received education payments from Medwest and Smith & Nephew.

Background: There is minimal work defining the economic impact of resident participation in shoulder arthroplasty. Thus, this study quantified the opportunity cost of resident participation in total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) by determining differences in operative time, relative value units (RVUs)/hour, and RVUs/case., Methods: A retrospective analysis of shoulder arthroplasty procedures were identified from the ACS-NSQIP database from 2006 to 2014 using CPT codes. Demographic, comorbidity, preoperative laboratory data and surgical procedure were used to develop matched cohorts. Mean differences in operative time, RVUs/case and RVUs/hour between attending-only (AO) cases and cases with resident involvement (RI) were examined. Cost analysis was performed to identify differences in RVUs generated per hour in dollars/case., Results: A total of 1786 AO and 1102 RI cases were identified. With the exception of PGY-3 and PGY-4 cases, RI cases had lower mean operative times compared to AO cases. The cost of RI was highest for PGY-3 ($199.87 per case) and PGY-4 ($9 .2 9) residents with all other postgraduate years providing a cost reduction., Discussion: Involvement of residents was associated with shorter operative times leading to a savings of $29.64 per case. Involvement of intermediate-level (PGY-3) residents were associated with increased costs that ultimately decreased as residents became more senior., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Xxxxxxx.- BMS reports publishing royalties, financial or material support from Nova Science Publishers. - CMJ reports paid consult, paid presenter or speaker, research support from Acumed, LLC; Paid consult, paid presenter/speaker for Biomet; Paid consultant for Depuy, A Johnson & Johnson Company; other financial or material support from Gotham Surgical; Paid consultant for Integra Lifesciences; financial or material support from Journal of the American Academy of Orthopaedic Surgeons; paid consultant from Smith& Nephew, Other financial or material support from Stryker, Paid consultant, paid presenter or speaker from Zimmer- WNL reports unpaid consulting agreements with Zimmer- The remaining authors (HWS, AJD, JRZ, ECB, DPT) reports no relevant conflicts of interests, (© The Author(s) 2022.)

Purpose: To evaluate the mid-term rate of revision arthroscopic rotator cuff repair as well as ipsilateral shoulder reoperations after index rotator cuff repair performed with or without acromioplasty in the United States., Methods: The Medicare Standard Analytic File, which encompasses the entire Medicare billing and payment data, was queried between 2005 and 2014. Patients undergoing arthroscopic rotator cuff repair were identified and stratified based on whether ipsilateral acromioplasty was concurrently performed using Current Procedural Terminology codes. Groups were matched by age, sex, year of index procedure, and Elixhauser index at a 2:1 ratio. Primary end point was defined as undergoing a repeat ipsilateral shoulder surgery related to the rotator cuff at 5 years of follow-up. Kaplan-Meier survival curves were constructed, and the 2 groups were compared using the log-rank test., Results: After matching, 54,209 shoulders in the rotator cuff repair with acromioplasty group and 26,448 shoulders in the rotator cuff repair without acromioplasty group were identified. Shoulders undergoing concurrent acromioplasty at index rotator cuff repair had a significantly increased rate of repeat ipsilateral cuff repair at 5 years postoperatively (8.5% vs 6.8%, P < .001). Similarly, there was an increased rate of reoperation of all types to the ipsilateral shoulder in cases where concurrent acromioplasty was performed (9.6% vs 9.1%, P < .001)., Conclusions: Using a large, national database, concurrent acromioplasty at the time of rotator cuff tear was found to be associated with both an increase rate of overall subsequent procedures and revision rotator cuff repair., Level of Evidence: III, retrospective comparative study., (© 2022 The Authors.)

Medial collateral ligament (MCL) injuries are typically managed non-operatively, with high rates of clinical success. However, patients who present with medial knee laxity with valgus stress testing of a fully extended knee, anteromedial rotatory instability, associated tibial plateau fracture, or multiligament injury or those who continue to be symptomatic after non-operative treatment may benefit from surgical intervention. Patients with a history of total knee arthroplasty who suffer MCL and posterior oblique ligament (POL) injuries represent a challenging patient population and often require surgical attention. In this Technical Note, we describe the preoperative assessment, decision making, and surgical technique for anatomic reconstruction of the superficial MCL and POL with an Achilles allograft in young, active patients with medial-sided knee injuries after total knee arthroplasty., (© 2022 The Authors.)

Objective: The objective of this study was to identify and describe the existing literature on criteria used for return to play (RTP) following surgical management of osteochondral defects of the knee., Design: A systematic review was performed to evaluate the surgical management of osteochondral defects of the knee in skeletally mature patients with a minimum of 2-year follow-up using Level I to IV studies in PubMed EMBASE from January 1998 to January 2016., Results: Twelve studies with at least one explicitly stated criterion for RTP were identified from a review of 253 published articles. The majority of included studies were Levels II and IV (33%, respectively). Autologous chondrocyte implantation (ACI) was exclusively evaluated in 33.3% of papers and 16.7% evaluated osteochondral allograft transplantation (OCA). Eight different RTP criteria were used alone or in combination across the reviewed studies and time was the most often utilized criterion (83.3%). Minimum time to RTP ranged from 3 to 18 months., Conclusions: This systematic review identifies current criteria used in the available literature to dictate RTP. Time from surgery was the most commonly employed criterion across the reviewed studies. Given the complex biological processes inherent to the healing of cartilaginous defects, further research is needed to design more comprehensive guidelines for RTP that are patient-centered and utilize multiple functional and psychological domains relevant to the process of returning to sport.

Osteochondritis dissecans (OCD) is a pathologic condition, most commonly affecting the knee joint in adolescents and young adults, although pathology can also be found at the elbow and ankle. Lesions to the medial femoral condyle are classically associated with varus alignment, while lesions to the lateral femoral condyle are seen in patients with valgus malalignment. Common risk factors for failed fixation of OCD lesions include unstable lesions to the lateral femoral condyle, screw breakage, older age, and closed physes. The purpose of this technical note is to describe the preoperative planning and step-by-step surgical approach for treatment of failed fixation of an OCD lesion of the posterior aspect of the lateral femoral condyle in young, active patients using an osteochondral allograft, a lateral opening wedge distal femoral osteotomy to correct malalignment, and a tibial tubercle osteotomy to facilitate access to the lesion., (© 2022 The Authors.)

Irreparable rotator cuff tears are those that cannot be restored back to their native footprint or those in which any repair will "almost certainly" lead to a structural failure as a result of poor tissue quality, degeneration, or retraction 1-3 . The InSpace subacromial balloon spacer (Stryker) was developed as a temporary spacer to restore anatomic relationships between the glenoid, humerus, and acromion to improve function and reduce pain associated with this challenging pathology., Description: First, a diagnostic arthroscopy is performed. In addition to evaluating the rotator cuff, care is taken to evaluate the tendinous insertion of the subscapularis as well as the long head of the biceps tendon, the labrum, and the articular cartilage of the joint. Synovectomy, bursectomy, and biceps tenodesis or tenotomy are performed as appropriate. For cases with an intact or repairable subscapularis, an acromioplasty is performed. The balloon size is determined with use of a probe through the lateral portal, measured from 1 cm medial to the superior glenoid rim to the lateral border of the acromion. The balloon-insertion device is advanced through the lateral portal, and the balloon is inflated with sterile saline solution after appropriate subacromial positioning. The balloon is then sealed and detached from the insertional device., Alternatives: Most treatment algorithms attempt to reduce pain and dysfunction with initial nonoperative treatment options 4 . For cases in which nonoperative treatment has failed, several surgical techniques have been described. These include partial rotator cuff repair, graft interposition, graft augmentation, superior capsular reconstruction, tendon transfers, and reverse total shoulder arthroplasty 5 ., Rationale: Ideal candidates for this procedure are patients with irreparable symptomatic rotator cuff tears. These patients should primarily complain of pain and have a preserved range of motion. Alternatively, if they have reduced range of motion because of pain, then their range of motion should improve after a corticosteroid injection. It is also important that the patient has an intact or repairable subscapularis. The balloon is beneficial in patients with medical comorbidities that would limit the use of other techniques dependent on biologic tissue healing or that would limit the use of arthroplasty. Poor candidates would be patients with pseudoparalysis, axillary nerve palsy, irreparable subscapularis tears, or severe glenohumeral arthritis (Hamada grade ≥3)., Expected Outcomes: A recent randomized clinical trial demonstrated the 2-year efficacy, safety, and benefits of the InSpace subacromial balloon spacer 6 . The authors reported significant early clinical benefit that was maintained over 2 years. Additionally, this benefit was equivalent or superior to the partial-repair control group at all included time points. The multiyear clinical efficacy of the subacromial balloon spacer in that study was similar to that reported by Familiari et al. and Senekovic et al. at 3 and 5 years postoperative, respectively 1,7 . Together, these studies would suggest that the initial benefit of the subacromial balloon spacer lasts beyond its biodegradation at 12 months postoperatively., Important Tips: Proper placement of the lateral portal should be made parallel to the supraglenoid tubercle. Such placement allows easy insertion and orientation of the balloon at the midpoint of the supraglenoid tubercle.Arthroscopic evaluation of the subscapularis must be performed. For cases with a torn subscapularis, partial or complete repair is recommended to maximize anteroposterior coupling forces that are critical to the function of the balloon.Preservation of the medial bursa and coracoacromial ligament will provide structural constraints against medial migration of the balloon into the supraspinatus fossa.Acromioplasty can be performed to create a smooth articulating surface and minimize friction on the implant, but should only be done in cases in which there is an intact or repairable subscapularis to minimize the risk of anterior escape.Adequate debridement, with acromioplasty as needed, will provide full visualization of the subacromial space to allow proper sizing of the spacer. Proper implant sizing will reduce the risk of subsequent balloon displacement postoperatively.If the measurement of the balloon is between 2 sizes, the larger spacer can be selected to limit displacement.Overinflation of the balloon can cause excessive tension on the deltoid. Underinflation increases the risk of escape. To optimize inflation of the balloon, the senior author prefers to fill the balloon to the recommended maximum volume and then remove saline solution until the balloon reaches the recommended final volume.If there is partial tearing of the long head of the biceps, a tenotomy or tenodesis is recommended., Acronyms and Abbreviations: ROM = range of motionRCT = randomized clinical trialTSA = total shoulder arthroplastySCR = superior capsular reconstructionRC = rotator cuffISP = infraspinatusSSP = supraspinatusSSC = subscapularisRI = rotator intervalCAL = coracoacromial ligamentCA = coracoacromialC = coracoidMRI = magnetic resonance imagingSAD = subacromial decompressionPRO = patient-reported outcomeFDA = U.S. Food and Drug Administration., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSEST/A373)., (Copyright © 2022 by The Journal of Bone and Joint Surgery, Incorporated.)

Background: The coronavirus-19 (COVID-19) pandemic has prompted a shift in health-care provision toward implementation of telemedicine. This study investigated demographic information on orthopaedic telemedicine utilization at a single academic orthopaedic institution in an effort to identify factors associated with telemedicine usage., Methods: Demographic and appointment data were collected from the electronic medical record during equivalent time periods prior to the onset of the COVID pandemic (pre-COVID) and during the COVID pandemic (peri-COVID). Multivariate analyses were performed to identify demographic and socioeconomic correlates of telemedicine utilization., Results: There was a significant increase in telemedicine visits between the eras of study, with significant differences in telemedicine usage in association with age, sex, marital status, English as the primary language, and insurance type (p < 0.001). Multivariate analyses found American Indian/Alaska Native (adjusted odds ratio [aOR] = 0.487, p = 0.004), Black/African American (aOR = 0.622, p < 0.001), Native Hawaiian/other Pacific Islander (aOR = 0.676, p = 0.003), and Asian (aOR = 0.731, p < 0.001) race to be significantly associated with decreased telemedicine usage. Additionally, male sex (aOR = 0.878, p < 0.001) and a non-commercial insurance plan (p < 0.001) were significantly associated with decreased telemedicine usage., Conclusions: Non-White race, non-commercial insurance plans, and male sex were associated with decreased telemedicine utilization. Further investigation is needed to characterize and better identify underlying factors contributing to disparities in telemedicine access and utilization., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSOA/A373)., (Copyright © 2022 The Authors.

Objective: The aim of this study is to assess the variability of postoperative rehabilitation protocols used by orthopedic surgery residency programs for osteochondral autograft transplantation (OAT) and osteochondral allograft transplantation (OCA) of the knee., Design: Online postoperative OAT and OCA rehabilitation protocols from US orthopedic programs and the scientific literature were reviewed. A custom scoring rubric was developed to analyze each protocol for the presence of discrete rehabilitation modalities and the timing of each intervention., Results: A total of 16 programs (10.3%) from 155 US academic orthopedic programs published online protocols and a total of 35 protocols were analyzed. Twenty-one protocols (88%) recommended immediate postoperative bracing following OAT and 17 protocols (100%) recommended immediate postoperative bracing following OCA. The average time protocols permitted weight-bearing as tolerated (WBAT) was 5.2 weeks (range = 0-8 weeks) following OAT and 6.2 weeks (range = 0-8 weeks) following OCA. There was considerable variation in the inclusion and timing of strength, proprioception, agility, and pivoting exercises. Following OAT, 2 protocols (8%) recommended functional testing as criteria for return to sport at an average time of 12.0 weeks (range = 12-24 weeks). Following OCA, 1 protocol (6%) recommended functional testing as criteria for return to sport at an average time of 12.0 weeks (range = 12-24 weeks)., Conclusion: A minority of US academic orthopedic programs publish OAT and OCA rehabilitation protocols online. Among the protocols currently available, there is significant variability in the inclusion of specific rehabilitation components and timing of many modalities. Evidence-based standardization of elements of postoperative rehabilitation may help improve patient care and subsequent outcomes.

The common peroneal nerve (CPN) runs laterally around the fibular neck and enters the peroneal tunnel, where it divides into the deep, superficial, and recurrent peroneal nerves. CPN entrapment is the most common neuropathy of the lower extremity and is vulnerable at the fibular neck because of its superficial location. Schwannomas are benign, encapsulated tumors of the nerve sheath that can occur sporadically or in cases of neurocutaneous conditions, such neurofibromatosis type 2. In cases with compressive neuropathy resulting in significant or progressive motor loss, decompression and neurolysis should be attempted. We present a technical note for the treatment of CPN compressive neuropathy in the setting of a previous ipsilateral schwannoma removal with a minimally invasive surgical approach and neurolysis of the CPN at the fibular neck., (© 2022 The Authors.)

Objective: To assess the variability of postoperative rehabilitation protocols used by orthopedic surgery residency programs for microfracture of femoral condyle and patellofemoral lesions of the knee., Design: Online postoperative microfracture rehabilitation protocols from US orthopedic programs and the scientific literature were reviewed. A custom scoring rubric was developed to analyze each protocol for the presence of discrete rehabilitation modalities and the timing of each intervention., Results: A total of 18 programs (11.6%) from 155 US academic orthopedic programs' published online protocols and a total of 44 protocols were analyzed. Seventeen protocols (56.7%) recommended immediate postoperative bracing for femoral condyle lesions and 17 (89.5%) recommended immediate postoperative bracing for patellofemoral lesions. The average time to permitting weight-bearing as tolerated (WBAT) was 6.1 weeks (range, 0-8) for femoral condyle lesions and 3.7 weeks (range, 0-8 weeks) for patellofemoral lesions. There was considerable variation in the inclusion and timing of strength, proprioception, agility, and pivoting exercises. For femoral condyle lesions, 10 protocols (33.3%) recommended functional testing prior to return to sport at an average of 23.3 weeks postoperatively (range, 12-32 weeks). For patellofemoral lesions, 4 protocols (20.0%) recommended functional testing for return to sport at an average of 21.0 weeks postoperatively (range, 12-32 weeks)., Conclusion: A minority of US academic orthopedic programs publish microfracture rehabilitation protocols online. Among the protocols currently available, there is significant variability in the inclusion of specific rehabilitation components and timing of many modalities. Evidence-based standardization of elements of postoperative rehabilitation may help improve patient care and subsequent outcomes.

Background: Orthopaedic injuries in Major League Baseball (MLB) players can have a tremendous impact on player health, longevity, salaries, and time lost from play., Purpose: To summarize all data published between January 1980 and August 2019 on truncal and lower extremity orthopaedic injuries sustained by MLB players., Methods: A literature review of studies examining injuries in MLB was performed using the PubMed and Embase databases. Included studies focused on truncal and lower extremity injuries in professional baseball players. Studies pertaining to nonorthopaedic injuries, and case reports, were excluded., Results: A total of 41 articles met the inclusion criteria and were selected for the final analysis. Articles were divided based on anatomic region of injury: hip and pelvis (16%), thigh (15%), truncal (14%), knee (13%), and ankle (11%). Most studies (83.7%) were level 3 evidence. Most studies obtained data using publicly available internet resources (29.8%) compared with the MLB Health and Injury Tracking System (22.1%)., Conclusion: This review provides physicians with a single source of the most current literature regarding truncal and lower extremity orthopaedic injuries in MLB players. Most research was published on hip and pelvic, truncal, and thigh injuries and consisted of level III evidence., (Copyright © 2021 The Authors.

Background: The P value is a statistical tool used to assess the statistical significance of clinical trial outcomes in orthopedic surgery. However, the P value does not evaluate research quality or clinical significance. The Fragility Index (FI) is an alternative statistical method that can be used to assess the quality and significance of clinical research and is defined as the number of patients in a study intervention group necessary to convert an outcome from statistically significant to statistically insignificant or vice versa. The primary purpose of this study was to evaluate the statistical robustness of clinical trials regarding shoulder arthroplasty using the FI. The secondary goal was to identify trial characteristics associated greater statistical fragility., Methods: A systematic review of randomized clinical trials in shoulder arthroplasty was performed. The FI was calculated for all dichotomous, categorical study outcomes discussed in the identified studies. Descriptive statistics and the Pearson correlation coefficient were used to evaluate all studies and characterize associations between study variables., Results: A total of 13 randomized controlled trials were identified and evaluated; these trials had a median sample size of 47 patients (mean, 54 patients; range, 26-102 patients) and a median of 7 patients (mean, 5.8 patients; range, 0-14 patients) lost to follow-up. The median FI was 6 (mean, 5; range, 1-11), a higher FI than what has been observed in other orthopedic subspecialties. However, the majority of outcomes (74.4%) had an FI that was less than the number of patients lost to follow-up, and most outcomes (89.7%) were statistically insignificant., Conclusion: Randomized controlled trials in shoulder arthroplasty have comparable statistical robustness to the literature in other orthopedic surgical subspecialties. We believe that the inclusion of the FI in future comparative studies in the shoulder arthroplasty literature will allow surgeons to better assess the statistical robustness of future research., (Copyright © 2020 The Authors.

Purpose: The aim of this study was to investigate the kinematics of the asymptomatic baseball batter's hips by comparing passive range of motion (PROM) and real-time active hip range of motion (AROM) and determine whether differences in ROM exist between lead and trail hips., Methods: Parameters of passive hip ROM were obtained using a goniometer and physical examination standards. Active hip ROM during batting swings was captured with the Dynamic Athletic Research Institute's markerless motion-capture system., Results: Twenty-nine elite-level baseball players were recruited for participation. Comparison of lead and trail hips showed no significant differences in PROM. Statistically significant differences in AROM were found between lead and trail legs with large effect sizes for flexion (mean difference [MD°], 11.22), extension (MD°, 30.30), abduction (MD°, 6.24), adduction (MD°, 18.63), external rotation (MD°, 14.87) and total arc of rotation (MD°, 17.17) ( P < .001 for all). External rotation in the lead hip approached maximum passive endpoint during early phases of the swing, whereas trail hip extension reached maximum passive endpoint during follow-through., Conclusion: There is a significant difference in the AROM of the lead and trail hips during the batting swing, with active extension in the trail hip, active external rotation of the lead hip, and total arc of rotation of the lead hip nearing their respective passive endpoints and suggesting a potential for bony interaction in the hips of baseball batters., Level of Evidence: Level 3, Cross-Sectional Study., (© 2021 by the Arthroscopy Association of North America.

Ulnar collateral ligament (UCL) injuries are a common source of pain and disability in the overhead athlete and often result in notable loss of time from competition. Over the past 10 to 15 years, the prevalence of UCL injury and reconstruction has undergone a dramatic increase, making it imperative to determine which patients may benefit from a nonsurgical regimen. Nonsurgical treatment involves a multidisciplinary approach of rehabilitation with tailored physical therapy programs and, in certain cases, biologic adjuncts. Physical therapy protocols should focus on strengthening the periscapular muscles, rotator cuff, core musculature, and flexor pronator mass to help stabilize the injured elbow and prevent injury recurrence before the initiation of a progressive throwing program. The implementation of injury prevention programs has shifted the focus from just the elbow and have included the shoulder, legs, and core in an effort to help decrease the stress on the upper extremity. In addition, biologic therapies such as platelet-rich therapy are promising modalities to augment the conservative treatment of UCL injuries but remain under investigation. The purpose of this study is to review available strategies and outcomes for conservatively treating UCL injuries., (Copyright © 2021 The Authors.

The American Medical Association (AMA) and National Institutes of Health (NIH) currently suggest that health care materials be written at a sixth-grade reading level. Our study investigates the readability of online information on Achilles rupture and reconstruction. Achilles tendon rupture, Achilles tendon repair , and Achilles tendon reconstruction were queried using advanced search functions of Google, Bing, and Yahoo!. Individual websites and text from the first 3 pages of results for each search engine were recorded and categorized as physician based, academic, commercial, government and nongovernmental organization, or unspecified. Individual readability scores were calculated via 6 different indices: Flesch-Kincaid grade level, Flesch Reading Ease, Gunning Fog, SMOG, Coleman-Liau index, and Automated Readability Index along with a readability classification score and average grade level. A total of 56 websites were assessed. Academic webpages composed the majority (51.8%), followed by physician-based sources (32.1%). The average overall grade level was 10.7 ± 2.54. Academic websites were written at the highest-grade level (11.5 ± 2.77), significantly higher than physician-based websites ( P = .040), and only 2 were written at, or below, a sixth-grade reading level. Currently, online information on Achilles tendon rupture and reconstruction is written at an inappropriately high reading level compared with recommendations from the AMA and NIH. Level of Evidence : Level IV .

Background: The shoulder is a commonly injured area in hockey, yet information is lacking on the prevalence and effect of shoulder instability. Our study investigates the incidence of shoulder dislocation events in the National Hockey League (NHL) and the effects on return-to-play (RTP) and player performance. We hypothesize that NHL players would have high RTP rates without significant changes in performance after injury., Methods: NHL players who suffered in-season shoulder instability events between 2003-2004 and 2017-2018 seasons were identified. Demographic characteristics, incidence of injury, recurrences, RTP, and statistical performance data were collected. Postinjury performance was compared with experience-matched, era-matched, position-matched, and age-matched controls. A mixed generalized linear regression model was used to compare postinjury performance as a function of operative and nonoperative treatment., Results: A total of 57 players experienced 67 shoulder instability events with 98.5% of players returning to play after an average of 26.3 ± 20.8 regular season games missed. Surgery was performed in 47.8% of players with no recurrent injuries postoperatively. Nonoperatively managed players experienced a decrease in points per game ( P  = .034) compared with surgically treated patients. Recurrence occurred in 14.3% of conservatively managed players, with 33.3% experiencing a season-ending injury. Players with recurrent injuries missed significantly more career games compared with those treated initially with surgery ( P  = .00324)., Conclusion: Professional hockey players experience high rates of RTP with acceptable performance outcomes after shoulder instability events; however, recurrent injuries led to significantly more career games missed when treated nonoperatively at the time of injury., (© 2020 The Author(s).)

Purpose: To determine the risk of postoperative humeral fracture following tenotomy, open tenodesis and arthroscopic tenodesis of the long head of the biceps brachii., Methods: A retrospective review of deidentified patient data from the Medicare Standard Analytic File using the PearlDiver software was conducted to identify procedures performed between 2005 and 2014. Groups were matched by age, gender, region, and medical comorbidities., Results: We evaluated 157,163 patients who had undergone arthroscopic or open tenodesis or tenotomy of the long head of the biceps brachii over a 10-year period (2005-2014), and we identified 2,196 postoperative humeral fractures (1.4%). Matched subgroup analysis consisting of 44,292 patients demonstrated a statistically significant increase in humeral fracture risk in open (280; 1.26%) compared to arthroscopic tenodesis (232; 1.04%) with a P value of 0.03 and an odds ratio of 1.21. The majority of fractures were sustained by patients 65-74 years of age., Conclusion: In this study, an increased risk of postoperative humeral fracture was associated with open tenodesis of the LHB., Level of Evidence: III, Retrospective Comparative Trial., (© 2020 by the Arthroscopy Association of North America.

Background: The increase in ulnar collateral ligament (UCL) elbow reconstructions over the past 20 years has affected younger athletes more than any other age group. Although return to play and postoperative performance have been extensively studied in professional baseball players, outcomes in collegiate baseball players are less known., Purpose/hypothesis: The purpose of this study was to characterize return to play and changes in performance after UCL reconstruction (UCLR) in collegiate baseball players. We hypothesized that collegiate baseball players would have similar return-to-play rates compared with professional athletes and no significant differences in performance compared with matched controls., Study Design: Cohort study; Level of evidence, 3., Methods: Collegiate athletes undergoing UCLR by a single surgeon were identified. Postoperatively, individual collegiate career paths were analyzed through use of publicly available data from team websites, injury reports, and press releases. Data obtained included time to return to competition, number of collegiate seasons played after surgery, total games started and played, seasonal wins, losses, saves, innings played, hits, earned run average (ERA), home runs, shutouts, strikeouts, walks, and walks plus hit per inning pitched (WHIP). The UCLR group was compared with a matched control group of collegiate pitchers without elbow injury., Results: Of the 58 collegiate baseball players analyzed (mean ± SD age, 19.95 ± 1.19 years), 84.5% returned to play at the collegiate level. Players returned to competition at 16.98 ± 6.16 months postoperatively and competed for 1.60 ± 0.84 seasons postoperatively. In terms of career longevity, 81.0% of collegiate pitchers either completed their collegiate eligibility or remained on active rosters, and 2 players (4.1%) ultimately played at the professional level after UCLR. Compared with a matched cohort, the UCLR group had no significant differences in collegiate pitching performance statistics after surgery., Conclusion: College baseball players returned to play at a rate comparable with the rate published in prior literature on professional pitchers and often completed their collegiate playing eligibility postoperatively. Compared with controls, the UCLR group had no statistically significant differences in pitching performance postoperatively. Further studies are needed to determine the exact reasons why college players retire despite having endured extensive surgical and postoperative rehabilitation processes related to UCLR. Younger populations are experiencing elbow injuries at an increasing rate secondary to increased workloads at the amateur level. As these athletes matriculate into the collegiate ranks, they are at continued risk of sustaining UCL injury, and little explicit information is available on their prospects of return to play and career longevity after UCLR., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: D.P.T. has received grant support from Arthrex (via OrthoCarolina Research Institute) and educational support from Smith & Nephew and Peerless Surgical.

Background: Surgical duration is an independent predictor of short-term adverse outcomes after a variety of orthopedic procedures, both arthroscopic and open. However, this association in shoulder arthroplasty remains unclear. The purpose of this study was to identify the association between surgical duration and postoperative complications, as well as increased use of health care resources, after shoulder arthroplasty., Methods: Primary shoulder arthroplasty procedures performed from 2005 to 2016 were identified in the American College of Surgeons National Surgical Quality Improvement Program database using Current Procedural Terminology codes. Surgical duration was divided into 3 cohorts: (1) surgical procedures lasting less than 90 minutes, (2) those lasting between 90 and 120 minutes, and (3) those lasting more than 120 minutes. Baseline patient characteristics and outcome variables were compared using bivariate analysis. Outcome variables were compared using multivariate analysis., Results: Overall, 14,106 patients were identified. Longer surgical duration was significantly associated with younger age, male patients, higher body mass index, and use of general anesthesia, (P < .001 for each), as well as smoking history (P < .39). Relative to operative times shorter than 90 minutes, surgical procedures lasting more than 120 minutes had higher rates of any complication (P = .002), return to the operating room (P = .008), urinary tract infection (P = .02), non-home discharge (P < .001), blood transfusion (P < .001), and unplanned 30-day hospital readmission (P = .03)., Conclusion: Increasing surgical duration was associated with a variety of postoperative medical complications and increased use of health care resources including discharge to acute care facilities, blood transfusions, and hospital readmission. These data suggest that surgical duration should be considered for postoperative risk stratification, as well as patient counseling, and may be a surgeon-modifiable risk factor independent of patient risk factors., (Copyright © 2019 Journal of Shoulder and Elbow Surgery Board of Trustees.

Ankle fractures are common orthopaedic injuries often requiring open reduction and internal fixation. A variety of positions for plate placement exist for surgical fixation of distal fibula fractures, including direct lateral, posterior, or posterolateral. Direct lateral is more common, despite evidence that posterior and posterolateral placement is mechanically superior. However, concern for peroneal tendon injury from posterior plating remains. Our study investigates clinical and functional outcomes of patients who underwent operative fixation of distal fibula fractures with posterior or posterolateral plating over a 3-year period. Analyses were performed on 59 patients with at least 2 years of follow-up. Questionnaires were used to obtain demographic data, in addition to information regarding the presence of ankle pain, subsequent hardware removal, and Foot and Ankle Outcome Scores (FAOS). In patients with at least 2 years of follow-up (average 39.6 ± 10.6 months), 37.2% reported ongoing ankle pain; 11 patients underwent hardware removal (18.6%), with 8 patients undergoing removal because of hardware-related pain (13.6%). FAOS scores (n = 51) were as follows: pain (79.9 ± 22.3), activities of daily living (84.2 ± 22.6), symptoms (75.7 ± 23.5), sports (69.4 ± 31.6), and quality of life (58.3 ± 30.5). Posterior and posterolateral plating achieved good clinical and high functional outcomes across our study population. The percentage of hardware removal in our study was either equivalent to, or less than, historical controls for any type of fibular fixation, and removal may be helpful for those patients whose postoperative ankle pain is subjectively related to the hardware.

Background: Youth athletes are starting sports earlier and training harder. Intense, year-round demands are encouraging early sports specialization under the perception that it will improve the odds of future elite performance. Unfortunately, there is growing evidence that early specialization is associated with increased risk of injury and burnout. This is especially true of pediatric and adolescent baseball players., Purpose/hypothesis: The purpose of this investigation was to analyze national injury trends of youth baseball players. We hypothesized that while the total number of baseball injuries diagnosed over the past decade would decrease, there would be an increase in adolescent elbow injuries seen nationally. A further hypothesis was that this trend would be significantly greater than other injuries to the upper extremity and major joints., Study Design: Descriptive epidemiology study., Methods: Injury data from the National Electronic Injury Surveillance System, a United States Consumer Product Safety Commission database, were analyzed between January 1, 2006, and December 31, 2016, for baseball players aged ≤18 years. Data were collected on the location of injury, diagnosis, and mechanism of injury., Results: Between 2006 and 2016, an estimated 665,133 baseball injuries occurred nationally. The mean age of the injured players was 11.5 years. The most common injuries diagnosed included contusions (26.8%), fractures (23.6%), and strains and sprains (18.7%). Among major joints, the ankle (25.6%) was most commonly injured, followed by the knee (21.3%), wrist (19.2%), elbow (17.7%), and shoulder (16.2%). The incidence of the ankle, knee, wrist, and shoulder injuries decreased over time, while only the incidence of elbow injuries increased. A linear regression analysis demonstrated that the increasing incidence of elbow injuries was statistically significant against the decreasing trend for all baseball injury diagnoses, as well as ankle, knee, wrist, hand, and finger injuries ( P < .05). Additionally, the only elbow injury mechanism that increased substantially over time was throwing., Conclusion: The current investigation found that while the incidence of baseball injuries sustained by youth players is decreasing, elbow pathology is becoming more prevalent and is more commonly being caused by throwing. Given that the majority of elbow injuries among adolescent baseball players are overuse injuries, these findings underscore the importance of developing strategies to continue to ensure the safety of these youth athletes., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: B.S. has received educational support from Smith & Nephew and Arthrex.

Background: Investigations specifically delineating the safest and most efficacious components of physical therapy after ulnar collateral ligament (UCL) reconstruction of the elbow are lacking. As such, while a number of recommendations regarding postoperative therapy have been published, no validated rehabilitation guidelines currently exist., Purpose: To assess the variability of rehabilitation protocols utilized by orthopaedic residency programs in the United States (US) and those described in the scientific literature., Study Design: Cross-sectional study., Methods: Online UCL reconstruction rehabilitation protocols from US orthopaedic programs and from the scientific literature were reviewed. A comprehensive scoring rubric was developed to assess each protocol for the presence of various rehabilitation components as well as the timing of their introduction., Results: Overall, 22 protocols (14%) from 155 US Electronic Residency Application Service (ERAS) orthopaedic programs and 8 protocols published in the scientific literature detailing UCL reconstruction postoperative rehabilitation were identified and reviewed. After reconstruction, the majority of ERAS and review article protocols (77% and 88%, respectively) advised immediate splinting at 90° of elbow flexion. The mean time to splint discontinuation across all protocols was 2.0 weeks (range, 1-3 weeks). There was considerable variability in elbow range of motion recommendations; however, most protocols detailed goals for full extension and full flexion (>130°) at a mean 5.3 weeks (range, 4-6 weeks) and 5.5 weeks (range, 4-6 weeks), respectively. Significant diversity in the inclusion and timing of strengthening, proprioceptive, and throwing exercises was also apparent. Thirteen ERAS (59%) and 7 review article (88%) protocols specifically mentioned return to competition as an endpoint. ERAS protocols permitted return to competition significantly earlier than review article protocols (29.6 vs 39.0 weeks, respectively; P = .042)., Conclusion: There is notable variability in both the composition and timing of rehabilitation components across a small number of protocols available online. While our understanding of postoperative rehabilitation for UCL reconstruction evolves, outcome-based studies focused on identifying clinically beneficial modalities and metrics are necessary to enable meaningful standardization., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: E.C.M. has received educational support from Pinnacle and Smith & Nephew, consulting fees from Smith & Nephew, and hospitality payments from Smith & Nephew and Stryker.

Background: Youth sports specialization has become more prevalent despite consequences such as increased injury rates and burnout. Young athletes, coaches, and parents continue to have misconceptions about the necessity of sports specialization, giving athletes the encouragement to focus on a single sport at a younger age., Purpose: To characterize the motivations for specialization and determine when elite athletes in various individual and team sports made the decision to specialize., Study Design: Cross-sectional study; Level of evidence, 3., Methods: A Likert-style survey was developed and distributed to athletes from two National Collegiate Athletic Association (NCAA) Division I institutions. The survey's Flesch-Kincaid grade level was 6.3. Statistical analysis was performed via the Student t test, where a P value less than .05 was considered significant., Results: A total of 303 athletes with a mean ± SD age of 19.9 ± 1.52 years across 19 sports were surveyed; 94.7% of specialized athletes had previously played another organized sport prior to college, and 45% of athletes had played multiple sports up to age 16 years. The mean age of specialization was 14.9 years, with a significant difference between athletes competing in team (15.5 years) and individual (14.0 years) sports ( P = .008). Males in individual sports specialized earlier than those in team sports ( P ≤ .001). Nearly one-fifth (17.4%) of athletes reported specializing at age 12 years or earlier. Personal interest, skill level, time constraints, and potential scholarships were the most important reasons for specialization overall. For individual sports, the motivations for specialization were similar, but collegiate ( P < .001) or professional ( P < .001) ambitions were significantly larger contributing factors., Conclusion: Early sports specialization is uncommon among NCAA Division I athletes for most team sports, whereas individual sports tend to have athletes who specialize earlier and are more motivated by professional and collegiate goals. This study characterized the timing of specialization among elite athletes, providing a basis for understanding the motivations behind youth sports specialization. Physicians should be prepared to discuss the misconception that early sports specialization is necessary or common among most team-focused collegiate-level athletes. Knowing the motivations for sports specialization will guide clinicians in their discussions with youth athletes., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: N.N.D. has received educational support from FujiFilm SonoSite, receives research support from DePuy, and is a consultant for Flexion Therapeutics.

Background: Achilles tendon rupture (ATR) is a common injury with increasing incidence. Several risk factors have been identified; however, little is known about seasonal variations in injury prevalence. Previous reports have generated mixed results, with no clear consensus in the literature. The purpose of this investigation was to retrospectively review ATRs seen at a major academic orthopaedic surgery department in New York City to determine whether a statistically significant seasonal pattern of ATRs exists., Methods: A retrospective chart review was conducted, identifying patients with an acute ATR. Patients were excluded if they had a chronic rupture, laceration, débridement for tendinitis, Haglund deformity, or other nonacute indications for surgery. Date and mechanism of injury were determined from the clinical record., Results: The highest rate of injury was seen in spring ( P = 0.015) and the lowest in fall ( P < 0.001), both of which were statistically significant. Overall, no statistically significant difference was noted in summer or winter, although more injuries were seen in summer. When only sports-related injuries are considered, a similar trend is seen, with most injuries occurring in spring (n = 48, P = 0.076) and fewest in fall (n = 25, P = 0.012); however, only the lower number in fall reaches statistical significance. No statistically significant difference was noted between seasons when only non-sports-related injuries were considered., Conclusion: A statistically significant increase was noted in the incidence of ATRs in spring and a statistically significant decrease in fall. The need for recognition of risk factors and preventive education is increasingly important in the orthopaedic surgery community and for primary care physicians, athletic trainers, coaches, and athletes., Level of Evidence: Prognostic level IV.

Introduction: Citation number can be used as a marker of a scientific article's influence. This study sought to determine and characterize the most-cited investigations on lateral epicondylitis and identify the most influential studies pertaining to this pathology., Methods: The Institute for Scientific Information Web of Science database was queried for articles investigating lateral epicondylitis, and the 50 most-cited articles were selected. For each article, number of citations, citation density, journal, publication year, country of origin, language, article type, article subtype, and level of evidence were recorded., Results: Citation numbers ranged from 72 to 332 (mean, 127.4), and densities ranged from 1.6 to 34.0 (mean, 9.4). Articles were published across 26 different journals. Most articles (41) were clinical, with randomized controlled trials (29.3%) being the most commonly cited articles., Discussion: Compared with previous investigations looking at citation density within orthopaedics, the most commonly cited clinical articles on lateral epicondylitis had a high percentage of level I or II evidence (39.0%). This compilation of the literature can aid in establishing reading curriculums for trainees in both orthopaedic residencies and fellowships. This is a Level V study.

Purpose: To investigate the current readability of online information pertaining to hip arthroscopy., Methods: The terms "hip arthroscopy" and "hip scope" were entered into the advanced search functions of Google, Yahoo!, and Bing on March 25, 2017, and results from the first 3 pages were analyzed. Results were required to be unique, accessible websites with information about hip arthroscopy conveyed primarily via analyzable text. Two reviewers applied inclusion criteria to the initial 97 results, discussing to reach consensus in cases of disagreement. Overall, 60 unique results were reviewed with 48 meeting inclusion criteria. Websites were categorized as physician-sponsored, academic, commercial, governmental and nonprofit organization (NPO), or unspecified. Readability was measured via 6 different indices: the Flesch-Kincaid grade level (FKGL), Flesch Reading Ease (FRE), Gunning Fog Score, SMOG Index, Coleman-Liau Index (CLI), and Automated Readability Index (ARI) along with an average grade level and readability classification score., Results: Forty-eight unique websites were assessed for readability, with physician-sponsored webpages composing the majority (47.92%) followed by academic sources (35.42%). The webpages' average grade level, incorporating information from all 6 metrics, was 12.79 ± 1.98., Conclusions: The current readability of online information pertaining to hip arthroscopy is at an inappropriately high reading level compared with the sixth-grade level recommended by the American Medical Association and National Institutes of Health, thus introducing significant barriers to understanding for many patients. Online materials should be edited to reduce word and sentence length and complexity, use simpler terms, and minimize use of passive voice to facilitate patient knowledge acquisition and understanding of online information about hip arthroscopy., Clinical Relevance: This study shows that the current readability of online information on hip arthroscopy exceeds the suggested sixth-grade reading level. It also emphasizes the need for simplifying written materials and offers specific suggestions on doing so to increase accessibility of information for patients., (Copyright © 2018 Arthroscopy Association of North America.

Background: The optimal postoperative rehabilitation protocol following repair of complete proximal hamstring tendon ruptures is the subject of ongoing investigation, with a need for more standardized regimens and evidence-based modalities., Purpose: To assess the variability across proximal hamstring tendon repair rehabilitation protocols published online by United States (US) orthopaedic teaching programs., Study Design: Cross-sectional study., Methods: Online proximal hamstring physical therapy protocols from US academic orthopaedic programs were reviewed. A web-based search using the search term complete proximal hamstring repair rehabilitation protocol provided an additional 14 protocols. A comprehensive scoring rubric was developed after review of all protocols and was used to assess each protocol for both the presence of various rehabilitation components and the point at which those components were introduced., Results: Of 50 rehabilitation protocols identified, 35 satisfied inclusion criteria and were analyzed. Twenty-five protocols (71%) recommended immediate postoperative bracing: 12 (34%) prescribed knee bracing, 8 (23%) prescribed hip bracing, and 5 (14%) did not specify the type of brace recommended. Fourteen protocols (40%) advised immediate nonweightbearing with crutches, while 16 protocols (46%) permitted immediate toe-touch weightbearing. Advancement to full weightbearing was allowed at a mean of 7.1 weeks (range, 4-12 weeks). Most protocols (80%) recommended gentle knee and hip passive range of motion and active range of motion, starting at a mean 1.4 weeks (range, 0-3 weeks) and 4.0 weeks (range, 0-6 weeks), respectively. However, only 6 protocols (17%) provided specific time points to initiate full hip and knee range of motion: a mean 8.0 weeks (range, 4-12 weeks) and 7.8 weeks (range, 0-12 weeks), respectively. Considerable variability was noted in the inclusion and timing of strengthening, stretching, proprioception, and cardiovascular exercises. Fifteen protocols (43%) required completion of specific return-to-sport criteria before resuming training., Conclusion: Marked variability is found in both the composition and timing of rehabilitation components across the various complete proximal hamstring repair rehabilitation protocols published online. This finding mirrors the variability of proposed rehabilitation protocols in the professional literature and represents an opportunity to improve patient care., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: C.S.A. receives royalties from Arthrex; receives research support from Arthrex, Major League Baseball, and Stryker; has stock/stock options in At Peak; and receives publishing royalties from Lead Player.

Study Design: This study determines the rate of change in the scoliosis surgery plan in cases presented in preoperative indications conference., Objectives: To determine the effect of preoperative indications conference on the plan of surgery and to identify characteristics that increased the likelihood of change., Summary of Background Data: Preoperative indications conferences are used as a teaching and planning tool. Levels of fusion, construct options, and necessity for osteotomies are often debated in the planning of scoliosis surgery., Methods: Scoliosis surgeries were presented at preoperative indications conference with four attending pediatric orthopedic surgeons present. The operative surgeon committed to a surgical plan before conference. A consensus-based plan was made without knowledge of the operative surgeon's preconference plan. Changes of plan were classified as major, minor, or no change., Results: Of the 107 surgical plans, 50 were index surgeries, 13 were revisions, and 44 were scheduled growing rod lengthenings. There were two major changes, including a change to a growing construct from planned fusion, and a change in fusion levels in an adolescent idiopathic scoliosis (AIS) patient. There were 13 minor changes, which included changes in fusion levels (1 to 3; mean = 1.23) and the addition of an osteotomy. The rate of change was 28% for index surgeries and 7.69% for revisions. Of the 14 changes in the 50 index surgeries, there were 8 AIS, 3 cerebral palsy, 1 congenital scoliosis, 1 Ehlers-Danlos, and 1 patient with an undetermined neuromuscular condition. There was 1 change in 13 revision surgeries. There were no changes for growing rod lengthenings and no cancellations as a result of indications conference., Conclusions: Although revision scoliosis surgery is complex, index AIS/JIS surgery was most subject to the influence of indications conference. This likely reflects controversy around choosing levels of fusion., Level of Evidence: IV., (Copyright © 2016 Scoliosis Research Society. Published by Elsevier Inc. All rights reserved.)
