Purpose The purpose of this study was to evaluate the short-term patient-reported outcomes of superior capsular reconstruction (SCR) and identify factors contributing to the success or failure of the procedure at 2 years. Methods A retrospective review was performed on data prospectively collected from the Surgical Outcomes System database. Patient-reported outcomes (PROMs) including American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, visual analog scale for pain, and Veterans RAND 12-Item Health Survey (VR-12) were evaluated at a minimum of 2 years postoperatively and reported using a minimal clinically important difference (MCID) and the percent of maximal possible improvement (MPI). In addition, preoperative and intraoperative variables were evaluated in patients with and without a postoperative improvement in ASES and SANE scores meeting the threshold of MCID. Results Two-year follow-up data were available for 350 patients. Statistically significant improvements were noted in all PROMs at 2-year follow-up. In total, 240 patients (68.8%) achieved an MCID improvement of >17.5 in ASES score, and 185 patients (52.9%) achieved an MCID of >29.8 improvement in the SANE score. Primary SCRs were associated with a higher MPI in the ASES score (60.1% ± 39.8% vs 40.4% ± 47.9%; P = .025) and VR-12 physical score (14.0% ± 13.8% vs 8.0% ± 14.7%; P = .028) compared to revision repairs. Only diabetes was identified as a predictor of SANE score improvement (64.5% vs 62.2%; P = .041). Conclusions SCR is associated with improvement in patient-reported outcomes at short-term follow-up, with 53% to 69% of patients achieving an improvement considered to meet the MCID. Greater improvement is expected when SCR is performed as a primary procedure rather than as a revision procedure for failed rotator cuff repair.

OBJECTIVE/HYPOTHESIS To evaluate clinical outcomes following failed endoscopic extraction of salivary calculi and to assess any relation between clinical outcome and calculi location, number, size, and mobility. If sialendoscopy fails to extract the calculus, subsequent spontaneous passage of the calculus out of the ductoglandular system or secondary effects of sialendoscopy could mitigate the clinical impact of a residual sialolithiasis. STUDY DESIGN Prospective observational study. METHODS Prospective comparative study of endoscopic procedures for sialolithiasis performed in the Manukau Surgery Center, in Auckland, New Zealand, from 2010 to 2020. The recurrent symptoms and the variables related to the need for additional surgical intervention for salivary calculi were analyzed. RESULTS Among the 465 sialendoscopy procedures, 154 (33.1%) were for obstructive sialolithiasis. Among these, there were 30 (19.4%) with unsuccessful stone extraction with re-operation for these failures performed in 14 of the 27 failed submandibular cases (52%) and 2 of the 3 parotids (66.7%). Location of calculi was a significant factor in predicting the need of further surgery. Patients with perihilar stones were 5 times more likely to have a failed procedure (P = .001). If the stone was intraglandular, the likelihood increased to 8.5 times (P = .005). The likelihood for a revision procedure increased almost 11 times if the stone was intraglandular (P = .004). Calculi size, mobility, multiple calculi, and presence of concurrent stenosis did not correlate with need for further surgery. CONCLUSIONS A significant proportion of "failed" sialendoscopy did not require further intervention. Stone location was a significant factor in predicting a failed procedure and the need for re-intervention. Laryngoscope, 2021.

Purpose Various methods have been described for the treatment of anterior shoulder instability with glenoid bone loss. The incidence of recurrent dislocations following surgical intervention is high and, therefore, necessitates a reliable and replicable revision procedure. The purpose of this Technical Note is to describe a method of arthroscopic anatomic glenoid reconstruction using a distal tibial allograft and screw fixation in the setting of a failed Latarjet procedure with significant glenoid bone loss. Methods We describe in detail patient positioning, portal placement, steps of the diagnostic arthroscopy, and graft preparation using imaging and a detailed intraoperative arthroscopic technique. Level of Evidence Level 1, Shoulder; Level 2, Instability., Technique Video Video 1 Technical video illustrating the arthroscopic anatomic glenoid reconstruction using screw fixation in the setting of a failed Latarjet procedure with hardware removal. The patient is placed in the lateral decubitus position, and the right arm is prepped and draped in the usual fashion. The posterior portal is used as the viewing portal for diagnostic arthroscopy, and the anterosuperior portal is used as the viewing portal for the rest of the surgical steps.

Patients undergoing total shoulder arthroplasty (TSA) can have varying levels of improvement after surgery. As patients typically demonstrate a nonlinear recovery trajectory, advanced analysis investigating the degrees of variation in outcomes is needed. Latent class analysis (LCA) is a mixed and multilevel model that estimates random slope variance to evaluate heterogeneity in outcome patterns among patient subgroups and can be used to outline differing recovery trajectories. The purpose of this study was to determine recovery trajectory patterns after TSA and to identify factors that predict a given trajectory.Data from a prospectively collected single institutional database of patients undergoing anatomic and reverse TSA were utilized. Patients were included if they had American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores preoperatively, as well as postoperative scores at 6 weeks, 6 months, 1 year, and 2 years. Patients were excluded if they underwent a revision procedure or hemiarthroplasty or had prior infection. LCA was used to subdivide the patient cohort into subclasses based on postoperative recovery trajectory. This was performed for all patients as well as anatomic TSA and reverse TSA as separate groups. Unpaired Student t tests, analysis of variance, and Fisher exact test were used to compare classes based on factors including age, body mass index, sex, preoperative diagnosis, and type of arthroplasty.A total of 244 TSAs were included in the final analysis, comprising 89 anatomic TSA and 155 reverse TSA. In the combined group, LCA modeling revealed 3 patterns for recovery: Resistant Responders had low baseline scores (ASES30) and poor final results (ASES50), Steady Progressors had moderate baseline scores (ASES 30-50) with moderate final results (ASES 50-75), and High Performers had moderate baseline scores (ASES50) with excellent final results (ASES75). For anatomic TSA, we identified Delayed Responders with moderate baseline scores and a delayed response before ultimately achieving moderate final results, Steady Progressors with moderate baseline scores and a steady progression to achieve moderate final results, and High Performers who had moderate baseline scores and excellent final results. For reverse TSA, we identified Late Regressors with low baseline scores and poor final results, Steady Progressors with moderate baseline scores and moderate final results, and High Performers with moderate baseline scores and excellent final results.Patients recover in a heterogenous manner following TSA. Through LCA, we identified different recovery trajectories for patients undergoing anatomic TSA and reverse TSA.

Background The National Joint Registry (NJR) demonstrates a re-revision rate for primary knee arthroplasty of 14.2% at 7 years. The 2015 Getting it Right First Time (GIRFT) report highlighted that 58% of surgeons undertaking revision knee arthroplasty (RKA) performed fewer than five cases per year. It has been suggested that revision cases be centralised in specialist centres with a multidisciplinary team (MDT) approach. Such a hub and spoke or cluster models may still require revision surgery to be performed at relatively low volume units. Methods An analysis of RKA surgery performed in a four surgeon, lower volume revision knee unit over 10 years to December 2016 was undertaken. The effect of the introduction of a MDT was reviewed. The minimum follow up was two years. The primary outcome measure was re-revision. Hospital data as well as individual surgeon NJR reports were used to ensure all re-revisions were accounted for. Outcome scores were available for 68% of cases. Results There were 192 RKAs performed in 187 patients at a mean (stdev) of 6.3 (5.4) years from the index procedure. The mean age at surgery was 68.2 (10.9) years. Twenty nine (15.5%) patients had died at the time of final review. Twelve (6.3%) cases required a further revision procedure. The commonest complication was stiffness requiring MUA. The overall 7 year survivorship was 94.9% (95% CI 90.2–97.3). The mean Oxford score at 5.4 years was 30.4 (10.4). Conclusions RKA can be reliably performed at lower volume centres with appropriate MDT systems in place.

AIMS: The purpose of this study was to analyze the clinical outcomes after Eden-Hybinette procedure for revision surgery in recurrent anterior shoulder instability in patients with epilepsy. MATERIALS AND METHODS: We retrospectively evaluated eight such patients between 2015 and 2018. Four patients had failed Latarjet/Bristow procedure and two had failed arthroscopic Bankart procedure, while two had history of both the procedures. After medical control of epilepsy, Eden-Hybinette procedure was performed in all patients. WOSI score and Rowe shoulder score was recorded preoperatively and in subsequent post-operative follow-up. A paired t test was used to analyze and compare preoperative and postoperative outcomes and was considered significant if p value was

Background The purpose of this study is to identify and analyze primary revision arthroplasties of the shoulder in the Germany Shoulder Arthroplasty Registry. The objective is to provide demographic and clinical data of the included cases and information about the revision surgery itself and to compare the findings to other registry studies and clinical studies. Methods All documented cases of primary revision arthroplasties of the Germany Shoulder Arthroplasty Registry in the time period 2014-2018 (n = 975) were included in the initial data analysis. Exclusion criteria were multiple revisions and data sets with a missing link of the revision arthroplasty to the data set of the primary implantation leaving n = 433 cases that were included. SPSS software (IBM SPSS Statistics for Windows, version 24.0; IBM Corp., Armonk, NY, USA) was used for statistical analyses. Results The age of patients with revised anatomic implants (66.3 years) was significantly lower than that of patients with reverse implants (77.1 years) (P = .001). Female patients with anatomic and fracture implants were significantly older than their male counterparts (70.1 vs. 60.5 years, P = .001; 74.3 vs. 62 years, P = .019) and showed a significantly higher rate of revision than their male counterparts (P = .001). The reason for revision was significantly different for anatomic and reverse implant systems (P = .001). Aseptic loosening of either the humeral or glenoid component was the most common reason for revision for anatomic implants, whereas unspecified reasons, dislocation, and loosening of the glenosphere were the most common reasons for reverse implants. The most common type of revision procedure for anatomic implants was conversion to a reverse system in about one third of the cases. Most of the revisions of reverse implants were not specified and almost equally distributed for revision at the humeral or the glenoid side. Anatomic implants showed significantly better Constant-Murley scores (26.1 points) than reverse implants (19.6 points) (P = .001) and significantly better function before revision for passive flexion (P = .002), passive abduction (P = .015), active external rotation (P = .002), and passive external rotation (P = .002). Conclusion This study provides a well-documented basis to compare revision arthroplasties of the shoulder performed in Germany over the last decade as documented in the nationwide registry with other nationwide registries and with clinical studies. Especially, the detailed analysis of intraoperative and postoperative complications and the shoulder function at the time of revision offers new information in addition to the results of other registries.

To assess diagnostic imaging utilization and the proportion of negative appendectomies for pediatric appendicitis at US children's hospitals between 2004 and 2018.This was a retrospective study using data from the Pediatric Health Information System (PHIS) database. Pediatric patients (age: 0-17 years) who underwent an appendectomy at one of 32 children's hospitals from January 1, 2004, through September 30, 2018, were included. Patients were identified based on International Classification of Diseases, 9th revision and International Classification of Diseases, 10th revision procedure codes. Patient demographics, imaging performed, and the frequency of negative appendectomy were analyzed.The final study population consisted of 104,033 children. From 2004 to 2018, CT utilization decreased from 56.8% (2,951 of 5,198) to 18.6% (1,201 of 6,455; P.001). Ultrasound utilization increased from 26.4% (1,371 of 5,198) to 63.4% (4,093 of 6,455; P.001). Radiography utilization remained stable at 16.7% (870 of 5,198) and 15.8% (1,018 of 6,455; P = .160). MRI use increased from 0.1% (6 of 5,198) to 2.2% (143 of 6,455; P.001). During the study period, the negative appendectomy rate slightly decreased, from 3.74% (4,742 of 126,778 in 2004-2011) to 3.14% (4,258 of 135,561 in 2012-2018; P.001).There has been a shift in imaging of children with appendicitis over 15 years in the United States, because the use of CT has decreased and ultrasound use has increased. This shift has likely added value to the health care system without adversely affecting outcomes (negative appendectomy rate).

Background Short stems are usually uncemented prosthetics and are recommended in the treatment of traumatic or degenerative diseases of hip. In revision procedures for elderly patients with serious comorbidity, applying a short stem could reduce peri- and post-operative secondary surgical risks to femoral osteotomy, which are necessary for the removal of parts of the implant or acrylic cement from the medullary canal. There are no cases in the literature that apply a short stem for prosthetic revision by acrylic cement anchorage. Case summary A male patient had a left hip replacement in 1995 due to coxarthrosis. At the age of eighty the patient reported an accidental trauma and walked with pain in the left thigh. The X-ray highlighted the stem breakage in the distal section without fracturing the femoral cortex. The patient had various comorbidities (diabetes, anaemia, heart deficiency, and arrhythmia) presenting a high operation risk (ASA 4). During the revision procedure, the distal apex of the stem could not be removed from the femoral cortex. Because of the poor general health of the patient, the surgeon decided not to perform a Wagner femoral osteotomy to remove the distal section of the stem and decided to implant a short stem to avoid removing the stem section of the previous implant. The patient had his left femur X-rayed 15 d post-trauma. Conclusion A field of application of short stem may be the development of a cemented short stem to reduce the complexity of the revision procedure.

To characterize regional variation in the age of patients undergoing umbilical hernia repair to determine costs and subsequent care.We performed a cross-sectional descriptive study using a large convenience sample of US employer-based insurance claims from July 2012 to December 2015. We identified children younger than 18 years of age undergoing uncomplicated (not strangulated, incarcerated, or gangrenous) umbilical hernia repair as an isolated procedure (International Classification of Diseases, Ninth Revision procedure codes 53.41, 53.42, 53.43, or 53.49, International Classification of Diseases, Tenth Revision procedure code 0WQF0ZZ, or Current Procedural Terminology procedure codes 49580 or 49585).In all, 5212 children met criteria for inclusion. Children younger than age 2 years accounted for 9.7% of repairs, with significant variation by census region (6% to 14%, P .001). Total payments for surgery varied by age; children younger than 2 years averaged $8219 and payments for older children were $6137. Postoperative admissions occurred at a rate of 73.1 per 1000 for children younger than age 2 years and 7.43 for older children; emergency department visits were 41.5 per 1000 for children younger than age 2 years vs 15.9 for older children (P .001).Umbilical hernias continue to be repaired at early ages with large regional variation. Umbilical hernia repair younger than age 2 years is associated with greater costs and greater frequency of postoperative hospitalization and emergency department visits.

Objective We describe the clinical outcomes in patients with aggressive vertebral hemangiomas (AVHs) after total tumor excision and discuss the treatment options for AVHs. Methods A retrospective data review of 15 patients (6 men, 9 women) with AVHs who underwent total excision between 1996 and 2018 was performed. Results In total, 13 thoracic and 2 lumbar lesions were involved with 8 type A−D tumors and 7 type B−D tumors based on the Weinstein-Boriani-Biagini classification. All tumors showed low or low-iso signal intensity by T1-weighted magnetic resonance imaging. All patients received a combination of preoperative transarterial embolization and total tumor excision including the tumor margins. Eleven patients underwent total tumor excision as the initial surgery (total en bloc spondylectomy = 10 patients, piecemeal total tumor excision = 1 patient), and 4 underwent it as either a revision procedure 2 weeks after ineffective laminectomy or in the long-term follow-up (4–14 years) as a piecemeal total tumor excision. Intraoperative blood loss ranged from 150 to 3400 mL (mean, 1314 mL). None of the cases had a recurrence during the mean follow-up period of 128.4 ± 88.6 months. Conclusions Low signal intensity on T1-weighted magnetic resonance imaging was observed in all the patients with AVHs. The long-term clinical results of the preoperative transarterial embolization and total tumor excision were satisfactory. The effect of decompressive incomplete tumor excision is temporary for AVHs, and repeated tumor excision may be necessary because of tumor recurrence in the long term. Reliable total tumor excision during the initial surgery is desirable.

The needle revision procedure to address failing filtering blebs is a blind technique that might easily damage the scleral flap, conjunctiva, and choroid. We propose a new surgical procedure, infrared monitor-guided bleb revision, to perform bleb revision minimally invasively and effectively, and demonstrate the procedure in a patient. We developed the guided procedure with the infrared monitor to observe the bleb interior with greater contrast. Under the monitor, we dissect the hard fibrotic tissue with a bleb knife and, if necessary, remove adhesions using a needle and vitreous forceps. Finally, 5-fluorouracil is injected into the subconjunctiva. We have performed bleb revisions safely with clear visualization of the scleral flap using an infrared light. In the current case, the patient had good intraocular pressure control for about 1 year. The new infrared monitor-guided bleb revision procedure facilitates successful bleb revisions without damage to the underlying structures.

Background An arthroscopic Bankart operation is the most common operative procedure to treat shoulder instability. In case of recurrence, both Bankart and Latarjet procedures are used as revision procedures. The purpose of this study was to compare the re-recurrence rate of instability and clinical results after arthroscopic revision Bankart and open revision Latarjet procedures following failed primary arthroscopic Bankart operations. Methods Consecutive patients operatively treated for shoulder instability at Turku University Hospital between 2002 and 2013 were analyzed. Patients who underwent a primary arthroscopic Bankart operation followed by a recurrence of instability and underwent a subsequent arthroscopic Bankart or open Latarjet revision operation with a minimum of 1 year of follow-up were called in for a follow-up evaluation. The re-recurrence of instability, Subjective Shoulder Value, and Western Ontario Shoulder Instability index were assessed. Results Of 69 patients, 48 (dropout rate, 30%) were available for follow-up. Recurrent instability symptoms occurred in 13 patients (43%) after the revision Bankart procedure and none after the revision Latarjet procedure. A statistically and clinically significant difference in the Western Ontario Shoulder Instability index was found between the patients after the revision Bankart and revision Latarjet operations (68% and 88%, respectively; P = .0166). Conclusions The redislocation rate after an arthroscopic revision Bankart operation is high. Furthermore, patient-reported outcomes remain poor after a revision Bankart procedure compared with a revision Latarjet operation. We propose that in cases of recurring instability after a failed primary Bankart operation, an open Latarjet revision should be considered.

Introduction: Two-stage revision is the most frequently performed revision procedure of a (suspected) periprosthetic joint infection (PJI) after total knee arthroplasty (TKA). The reported results of this treatment show large variability between studies, ranging between 0 - 40 percent failure. The purposes of this study were to determine long term (1) reinfection rate, (2) re-revision rates for any reason, and (3) the reinfection rate of patients with positive cultures at reimplantation.Methods: We prospectively followed and retrospectively reviewed 113 consecutive two-stage revision TKAs, performed between 2003 and 2013 in our clinic with a minimum follow-up of 2 years. Diagnosis of PJI was based on the major Musculoskeletal Infection Society criteria for PJI.Results: After a mean follow-up of 94 months (range 24-172 months), infection recurred in 23 cases (23%). Of these, nine cases (9%) were defined as relapse (same micro-organism as index revision) and in 14 cases another causative was found (14%). In 11 patients debridement, antibiotics and retention of the prosthesis successfully eradicated the reinfection. After overall follow-up 17 patients (17%) underwent re-revision surgery, 11 patients (11%) due to an infection and 6 patients (6%) for aseptic reasons.Conclusions: Treatment of a (suspected) infection of a TKA by a two-stage revision had acceptable results based on re-revision and re-infection rates in the long term (>5 years), resembling the short-term results (

Background Trauma can cause large defects in the weight-bearing foot sole. The reconstruction of such defects poses a major challenge in providing a flap that is durable, sensate, and stable. The pedicled medial plantar flap has been commonly used for reconstructing heel and plantar forefoot defects; however, the ipsilateral instep region is usually compromised by trauma. The purpose of this article was to report the use of contralateral free medial plantar flaps for the coverage of weight-bearing plantar defects and to compare these with distant free flaps. Methods Between 2005 and 2019, 15 patients (10 men and 5 women) with weight-bearing foot plantar defects were treated with a contralateral medial plantar flap, 11 (7 men and 4 women) with either a latissimus dorsi flap or a scapular flap. The average age was 18.07 ± 10.14 years (range, 4-34 years) and 26.55 ± 13.05 years (range, 13-56 years), respectively. Surgery was performed as a primary or secondary reconstruction after a trauma by the same surgical team. Results The mean size of defects was 9.73 ± 3.55 × 6.43 ± 2.8 cm in the contralateral free medial plantar flap group and 17.14 ± 6.84 × 11.41 ± 4.29 cm in the free dorsal flap group. All flaps survived in both groups. In the instep flap group, the appearance was satisfactory, the flap was durable, and tactile sensation was preserved in all patients, and none required a revision procedure. Two patients experienced delayed union of the donor-site grafted skin. In the dorsal flap group, 5 patients complained of a partial necrosis or delayed union at the recipient site, and 9 developed recurrent ulcerations over the weight-\bearing area. Five patients achieved only partial sensation in the flap. Conclusions The contralateral medial plantar flap provides superior appearance, duration, and sensation over distant muscle flaps, without recurrent ulcerations. However, dorsal myocutaneous flaps may be used as a substitute when the defects are beyond the maximum boundaries of the instep area or are combined with bone loss.

Background. First metatarsophalangeal joint arthrodesis is the gold standard in the treatment of arthritis of the first MTP joint as well as an effective salvage procedure after unsuccessful primary forefoot procedures. The paper aims to present an evaluation of mid-term functional results and specify the causes of low postoperative satisfaction among patients. Material and methods. 44 patients who underwent operative treatment in the years 2012–2018 were assessed with the AOFAS-MTP, EFAS and VAS scores and a radiological evaluation after at least half a year of follow-up. Multiple factors were analysed with regard to their influence on functional results and overall patient satisfaction. Our results were then compared to those of the most recent meta-analysis. Results. The mean follow-up time was 27.4 months (from 6 to 82 months). The mean AOFAS-MTP score increased from 30.5 (SD 15.6) to 67.16 (SD 18.68), the mean EFAS score increased from 8.2 (SD 5.2) to 17.2 (SD 6.7), and the mean VAS score decreased from 7.6 (SD 1.6) to 3.2 (SD 2.5). Additionally, 35 patients (79.5%) were satisfied or very satisfied with the surgery, 9 patients (20.5%) reported their satisfaction as low or very low, while 6 patients (13.6%) required a revision procedure. Conclusions. Despite using methods of treatment comparable to those found in the literature and achieving similarly comparable functional and radiological results, the finding that a significant proportion of patients were not satisfied with the surgery shows the need for further investigation and optimization of operative techniques.

Purpose: To assess the use of calcium sulphate (CS) beads in the management of knee and hip periprosthetic joint infections (PJI) in terms of outcomes, complications and re-infection rates.Methods: A search of NICE healthcare database advanced search (HDAS) was conducted from its year of inception to October 2019 with the keywords: “Calcium Sulphate Beads” or “Calcium Sulfate Beads” or “Antibiotics beads” or “Stimulan” and “Arthroplasty” or “Hip Replacement” or “Knee Replacement” and “Periprothetic joint infection” or “Debridement, Antibiotics and implant retention” or “Revision”. A quality assessment was performed using the NIH study Quality Assessment Tool for case series.Results: Out of relevant 74 articles, 5 articles met the inclusion criteria. Variable outcomes and success rates have been reported in most of the patients. A small number of wound discharges and heterotrophic ossification (HO) were reported, which are occasionally symptomatic. Hypercalcemia is identified as a potential risk with the use of CS beads especially with doses over 40 cc per operation. The influence of CS beads on reinfection rate is reported in 4 out of 5 articles. Due to the case-mix and heterogenicity of the patients involved and the causative microorganism reported as well as varied procedures are undertaken including one and two stages revision and Debridement, Antibiotics and implant retention (DAIR), the influence of CS beads varied from high success to poor outcome. The poor outcome is higher if the primary procedure for the management of hip and knee PJI is DAIR rather than full revision.Conclusions: The use of CS beads in the treatment of PJI is a useful technique in delivering high doses of antibiotics locally. A favourable outcome is reported when antibiotics loaded CS is used as an adjuvant to revision procedure for PJI in hip and knee arthroplasty compared to its use as an adjuvant to DAIR procedure. There has been an increase in complications when higher volumes of beads are used, especially in subcutaneous structures and in high-risk patients. Another possible theoretical and unreported complication of CS beads is accelerating the wear rate in the artificial joint due to the possibility of causing abrasion to the bearing surfaces. The current evidence is not enough to indicate the superiority of antibiotic-loaded CS beads as an adjuvant for the treatment of PJI in Hip and Knee arthroplasty.

Revision total knee arthroplasty (TKA) is a challenging surgical procedure. Although good results are presented, the outcomes are worse in comparison with those of primary TKA, with a higher failure rate. The main reasons for the failure of revision TKA include: sepsis, loosening and instability. There are multiple variables linked to these results, and it is difficult to determinate the exact cause as it is often a multifactorial issue. These variables may be related to the quality of the index-procedure (TKA), to the revision procedure or to patient characteristics. The purpose of this review was to highlight the outcomes of revision knee arthroplasty and main factors that may influence the results. Considerable progress has been made during the last 30 years regarding infection treatment and prevention, complex revision prosthetic design and surgical technique development. Although the outcomes have improved over time, patients who undergo revision TKA may need further re-operations in the future.

Sequestrectomy in chronic osteomyelitis leads to large bony defect in some cases. It needs segemental bone grafting of which fibula is commonly used in children. Few instances might need revision graft due to fracture. We have done a technique of periosteal sparing fibular graft removal in a 9 year old child with the usage of regenerate of the same side for revision procedure. Donor and recipient site healed at 6 months and 2 years respectively with no ankle deformity. This is an easy and versatile technique which can be extrapolated to several other disorders requiring repeated bone graft.

Author(s): Ma, Gabrielle C; Bradley, Kendall E; Jansson, Hayley; Feeley, Brian T; Zhang, Alan L; Ma, C Benjamin | Abstract: IntroductionShoulder arthroplasty has become popular in the treatment of degenerative shoulder conditions in the United States. Shoulder arthroplasty usage has expanded to younger patients with increased surgical indications.MethodsReverse total shoulder arthroplasty (RTSA) and TSA patient records with the 1-year follow-up between 2015 and 2018 were queried from the nationwide PearlDiver Mariner Shoulder Database using International Classification of Disease-10 codes. Chi-square analysis was done to compare the demographics, surgical complications, and revision procedures between RTSA and TSA.ResultsFrom 2010 to 2018, there was an increase in shoulder arthroplasty cases because of RTSA. The overall surgical complication and revision procedure rates were 2.26% and 3.56% for RTSA, and 6.36% and 2.42% for TSA. Patients older than 50 years had statistically lower surgical complications after RTSA than TSA (2.25% versus 3.94%, P l 0.05), whereas no statistical difference between RTSA and TSA for patients younger than 50 years (10.06% versus 7.45%, P = 0.19). Male patients had higher RTSA complication rates (3.12% versus 2.28%, P l 0.05), whereas female patients had higher TSA (4.86% versus 5.92%, P l 0.05). History of tobacco, depression, and obesity were risk factors for higher complications.ConclusionRTSA has become more commonly done than TSA in the United States. Older patients who underwent shoulder arthroplasty had lower surgical complication. TSA had a higher surgical complication rate than RTSA for patients older than 50 years.

To analyze the long-term efficacy of the ventriculoatrial shunt (VAS) in pediatric patients with hydrocephalus, focusing on the atrial catheter and suitable revision procedures of the distal catheter following VAS malformation performed at our institution. The authors retrospectively analyzed data of 28 pediatric patients under the age of 10 years who were treated with VAS for hydrocephalus and who had a follow-up period of at least 5 years. A total of 42 atrial tube revision procedures were performed in 28 patients during the study period. The median atrial tube survival time due to atrial tube obstruction was 2.32 years (n = 31, range: 0.4–8.08 years). Atrial tube survival time was shorter in younger children (p

Trochleoplasty in patellofemoral instability has always been controversial. Most authors recognize the fundamental role of trochlear dysplasia in the genesis of patellar dislocation, and some strongly defend correcting the abnormality, yet others find it too dangerous or unnecessary. Misunderstanding or undervaluation of trochlear dysplasia leads to inappropriate or failed patellofemoral (PF) surgery, the iatrogenic complications of which are well known. Many surgeons miss a key aspect of trochlear dysplasia: the overhang or the prominence of the trochlea relative to the anterior femoral cortex, characterized by a supra-trochlear spur. Trochleoplasty should not be performed as a secondary or revision procedure, but as a primary procedure with clear indications, and the key to improved outcomes is to ensure the right indication for each patient, which can only be determined by understanding the extent of dysplasia in both the axial and sagittal planes.

Background This retrospective study aims to compare the outcome of the Latarjet procedure when used as a primary or revision procedure for recurrent anterior gleno-humeral instability. Methods One hundred and ninety-seven patients underwent 205 open Latarjet procedures during the period 2006–2015 (mean follow-up 5.6 years). Sixty shoulders had failure of a previous stabilisation requiring revision to the Latarjet procedure. Outcomes were measured using the Western Ontario Shoulder Instability Index and Quick Disabilities of the Arm, Shoulder and Hand score. Survival analyses were performed using Kaplan–Meier curves, and multiple linear regression modelling was utilised to identify predictors of functional outcome (p Results Two shoulders had recurrent dislocations in the cohort of 205 (1.0%). Six shoulders underwent further surgery for non-instability complications (2.9%). There were no significant differences in the clinical or functional outcome between patients undergoing a primary Latarjet procedure and those who required revision of a failed soft-tissue stabilisation. Ninety-two per cent of patients were satisfied with their shoulder following surgery. Patient-reported instability and satisfaction was significantly associated with poorer functional scores. Discussion The Latarjet procedure successfully prevents recurrent anterior instability and is associated with high levels of satisfaction. Patient-reported outcome measures suggest no difference between primary and revision procedures.

Total joint replacement is one the most effective methods for treatment of degenerative, systemic and posttraumatic diseases of the knee. However, up to 25% of patients remain dissatisfied with surgery outcomes. In the majority of cases the patients complain of pain in the operated joint. Identification of pain cause in the operated joint can turn to become a challenge for the surgeon.Purpose of the study — to identify the causes of pain syndrome basing on examination algorithm in patients after TKR as well as to assess the diagnostic value of each particular examination method.Materials and Methods. The authors analyzed results of comprehensive examination of 79 patients who complained of chronic knee pain after primary TKR and seeked medical help from the beginning of 2016 until December 2018. Inclusion criteria were as follows: knee prosthesis and presence of pain syndrome in the operated joint. Exclusion criteria: fistulous peri-prosthetic infection, suspected “culture-negative” infection and revisions. All patients included into the study were managed according to the standard algorithm of comprehensive examination.Results. The most likely causes of pain were identified during the examination. Infection was observed in 39 patients (49.4%), errors in three-dimensional positioning of components was considered as a probable cause of pain in 14 patients (17.7%), aseptic loosening was reported in 13 cases (16.5%), ligamentous instability — in 6 patients (7.6%), extraarticular pain origin was observed in 5 patients (6.3%) and peri-prosthetic fractures were reported in two patients (2.5%). The authors confirmed a combination of several pain causes in 17 patients (21.5%).Conclusion. Examination of patients with painfull knee joint prosthesis should be comprehensive due to potential combination of issues in each particular case. Integral and systematic approach to pain diagnostics in the operated joint is the “key to success” for planning further treatment tactics and for understanding the necessity and scope of revision procedure.

Background Previous research has indicated that unicompartmental arthroplasty may be an effective treatment for focal osteonecrosis in the knee; however, these reports have been composed of small patient cohorts and without characterization of the osteonecrotic lesions. Therefore, the purpose of this study was to investigate the effectiveness of unicompartmental arthroplasty for the treatment of focal osteonecrosis within the medial femoral condyle including an assessment of lesion size. Methods A consecutive series of >5,000 unicompartmental knee arthroplasties performed at a single institution was retrospectively reviewed to identify cases of medial femoral condyle osteonecrosis with a minimum 2-year follow-up. Lesion size was classified according to the ratio of lesion width to condylar width, as well as lesion depth relative to condylar depth. Patient-reported outcome measures and need for a revision procedure were studied. Results Sixty-four patients (32 males, 32 females; 65 knees) with a mean age of 64 years were included. The mean patient follow-up was 5.3 years (range, 2 to 12 years). The mean ratio of lesion width to condylar width was 64%, the mean lesion depth was 1.11 cm, and 82% of cases demonstrated subchondral collapse. At the time of the latest follow-up, patients demonstrated substantial improvements in the pain, function, and clinical components of the Knee Society Score, by 36, 25, and 51, respectively. Four patients (6%) required a revision, of which only 1 was for aseptic loosening of the femoral component. Conclusions Unicompartmental arthroplasty is an effective treatment for advanced-stage focal osteonecrosis of the medial femoral condyle. Loss of component fixation to the femoral condyle did not appear to be a substantial concern because there was only 1 femoral failure as a result of aseptic loosening, despite lesions affecting a significant portion of the femoral condyle.

Objective A growing body of evidence demonstrates that endonasal endoscopic dacryocystorhinostomy (eDCR) techniques provide comparable results to conventional external techniques. The purpose of this study was to evaluate long-term outcomes after powered endoscopic DCR without preservation of mucosal flaps for the management of acquired nasolacrimal duct obstruction performed by a single surgical team. Methods A retrospective review was performed of patients with epiphora secondary to acquired nasolacrimal duct obstruction who underwent eDCR without mucosal flap preservation from May 2003 to April 2013 at a tertiary referral medical center. Main outcome measures were subjective improvement in epiphora and assessment of anatomic patency based on lacrimal irrigation and endoscopic evaluation. Results Eighty patients (69 primary and 11 revision) totaling 103 procedures (87 primary, 16 revision) were available for analysis at a mean follow-up of 28.7 (range 6-114) months. At the most recent follow-up, 92 of 103 (89.3%) procedures had complete resolution of epiphora, and 10 of 103 procedures achieved mild intermittent epiphora. Complete resolution of epiphora was noted in 93.1% (81 of 87) of primary procedures and 68.8% (11 of 16) of revision procedures. Objective anatomic patency was confirmed in 98% (101 of 103). A revision procedure was required in 5.8% (6 of 103). Conclusion Outcomes of powered eDCR without the preservation of mucosal flaps compare favorably to previously reported results in the literature. These long-term results suggest that mucosal flap preservation is not required to achieve successful outcomes with eDCR. Level of evidence 4 Laryngoscope, 130:12-17, 2020.

Background The study evaluates patient-reported outcomes in revision shoulder arthroplasty (RevSA) according to etiology. Methods Twenty-three consecutive RevSA (minimum 2-year follow-up) were retrospectively reviewed. Patient-reported outcome (PRO) scores and range of motion were compared by the type of revision procedure and indication. Results EQ5D-QOL, VAS-pain, ASES, and forward elevation improved after RevSA. The infection group had least improvements. Revision to a reverse total shoulder arthroplasty (RTSA) demonstrated the most improvement in VAS-pain, forward elevation, and ASES. Conclusions Revision to RTSA significantly improved PRO scores compared to hemi- or total shoulder arthroplasty. RevSA for infection demonstrated the least improvement in outcomes.

BACKGROUND: Patellofemoral replacements (PFRs) have a higher rate of revision than unicompartmental knee arthroplasty or TKA. However, there is little information regarding why PFRs are revised, the components used for these revisions, or the outcome of the revision procedure. Some contend that PFR is a bridging procedure that can easily be revised to a TKA with similar results as a primary TKA; however, others dispute this suggestion. QUESTIONS/PURPOSES: (1) In the setting of a large national registry, what were the reasons for revision of PFR to TKA and was the level of TKA constraint used in the revision associated with a subsequent risk of rerevision? (2) Is the risk of revision of the TKA used to revise a PFR greater than the risk of revision after a primary TKA and greater than the risk of rerevision after revision TKA? METHODS: Data were obtained from the Australian Orthopaedic Association Joint Replacement Registry through December 31, 2016, for TKA revision procedures after PFR. Because revisions for infection may be staged procedures resulting in further planned operations, for the revision analyses, these were excluded. There were 3251 PFRs, 482 of which were revised to TKA during the 17-year study period. The risk of second revision was calculated using Kaplan-Meier estimates of survivorship for PFRs revised to TKAs, and that risk was compared with the risk of first revision after TKA and also with the risk of a second revision after revision TKA. Hazard ratios (HRs) from Cox proportional hazards models were used to compare second revision rates among the different levels of prosthesis constraint used in the index revision after PFR (specifically, cruciate-retaining versus cruciate-substituting). RESULTS: The main reasons for revising a PFR to TKA were progression of disease (56%), loosening (17%), and pain (12%). With the numbers available for analysis, there was no difference in the risk of a second revision when a PFR was revised to a cruciate-retaining TKA than when it was revised to a cruciate-substituting TKA (HR, 1.24 [0.65-2.36]; p = 0.512). A total of 204 (42%) of the PFR revisions had the patella component revised when the PFR was converted to a TKA. There was no difference in rates of second revision when the patella component was revised or not revised (HR, 1.01 [0.55-1.85]; p = 0.964). When we eliminated the devices that ceased to be used before 2005 (older devices), we found no change in the overall risk of repeat revision. The risk of a PFR that was revised to a TKA undergoing a second revision was greater than the risk of TKA undergoing a first revision (HR, 2.39 [1.77-3.24]; p < 0.001), but it was less than the risk of a revision TKA undergoing a second revision (HR, 0.60 [0.43-0.81]; p = 0.001). CONCLUSIONS: The risk of second revision when a PFR is revised is not altered if cruciate-retaining or posterior-stabilized TKA is used for the revision nor if the patella component is revised or not revised. The risk of repeat revision after revision of a PFR to a TKA was much higher than the risk of revision after a primary TKA, and these findings did not change when we analyzed only devices in use since 2005. When PFR is used for the management of isolated patellofemoral osteoarthritis, patients should be counselled not only about the high revision rate of the primary procedure, but also the revision rate after TKA. Further studies regarding the functional outcomes of these procedures may help clarify the value of PFRs and subsequent revisions. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Children with osteogenesis imperfecta suffer from frequent fractures and deformities due to skeletal fragility. Stabilisation of fractures, correction of deformity and intramedullary rodding result in decreased pain and improved function. Modern expandable intramedullary rods aim to provide lasting stability during growth, without an increase in complications. The aim of our study was to determine and compare the outcome of static Rush rods and expandable Fassier-Duval rods in terms of complications and reoperation rate. METHODS: We reviewed the records of a cohort of 17 children (seven female) with osteogenesis imperfecta (11 Sillence type III, six Sillence type IV) who were treated with intramedullary rods in the lower limb between 2011 and 2017. They had 64 rodding (38 femoral and 26 tibial) procedures (26 Rush rods and 38 Fassier-Duval rods). These were a primary procedure in 46, and a revision procedure after previous Rush rodding in 18 cases. RESULTS: The overall complication rate was 66% (n=42). There was a higher complication rate in the Rush rod group (81%, n=21) when compared to the Fassier-Duval group (55%, n=21)(p=0.035). The most frequent complication in the Rush rod group was distal deformity as the rod is outgrown (69%, n=18). The most frequent complication in the Fassier-Duval rod group was intramedullary migration due to a failure to expand (45%, n=17). Factors that were associated with increased risk of complications included younger age (p=0.031), type of rod (p=0.035), and deformity as an indication for surgery (77% complications, p=0.033). At a mean follow-up of 3.1 years, the reoperation rate in the Rush rod group was 58% (n=15). Comparatively, at a mean of 3.7 years follow-up, there were no reoperations in the Fassier-Duval group. CONCLUSIONS: Despite the numerous innovations, the surgical management of lower limb deformities and fractures in children with osteogenesis imperfecta remains challenging with a relatively high complication rate. The use of Fassier-Duval rods may result in a lower reoperation rate when compared to Rush rods, in the short term.

Background: Current approaches do not provide a practical method for the accurate prediction of a Cutibacterium periprosthetic joint infection (PJI) in failed arthroplasties. Thus, surgeons revising failed arthroplasties must decide whether to exchange the implants and to institute antibiotic treatment without knowing the results of cultures of deep specimens obtained at the revision procedure. This study tests the hypothesis that the results of preoperative culture specimens of the skin surface obtained in the clinic can predict the presence of culture-positive Cutibacterium PJIs. Methods: Revision shoulder arthroplasties performed between October 3, 2017, and February 4, 2020, that had both preoperative clinic culture specimens and surgical culture specimens were included in this analysis. Culture results were assigned a value from 0 to 4. The percentage of the total skin bacterial load contributed by Cutibacterium (Cutibacterium percentage) was determined. To reduce concern about contamination, a robust criterion for culture-positive Cutibacterium PJI was applied: ≥2 surgical specimens with a Cutibacterium value of ≥1. The predictive values for a culture-positive Cutibacterium PJI were determined for a clinic skin culture Cutibacterium value of >1 and a clinic skin percentage of Cutibacterium of ≥75%. Results: Eighteen cases met the inclusion criteria; of these, 7 (6 male patients) met our criterion for a culture-positive Cutibacterium PJI. For all patients, a preoperative clinic skin Cutibacterium value of >1 predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 89%, and a clinic skin Cutibacterium percentage of ≥75% predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 94%. For male patients, a preoperative clinic skin Cutibacterium value of >1 predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 91%, and a clinic skin Cutibacterium percentage of ≥75% predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 100%. Conclusions: A simple culture specimen of the unprepared skin surface obtained in a clinic prior to revision shoulder arthroplasty may provide valuable assistance to surgeons planning a revision arthroplasty.

Category: Ankle Arthritis Introduction/Purpose: The aim of this study was to investigate the surgical trends of primary total ankle arthroplasty (TAA) and revision procedure in South Korea from 2007 to 2017 using the national population-based data. Methods: We reviewed the national health insurance data of South Korea from 2007 to 2017. The data includes diagnosis codes, procedure codes, prescriptions, medical costs, and other demographic data. Trends of primary diagnosis for primary TAA were evaluated. Annual trends and incidences per 100,000 person-years of primary TAA and revision procedures as well as compound annual growth rate (CAGR) during the study period were analysed. Surgical trends according to patients’ age, hospital grades, and insurance systems were also evaluated. Results: Primary diagnosis for primary TAA was mostly degenerative arthritis (6501 cases, 90.5%). From 2007 to 2017, the total number of cases of primary TAA and revision procedures was 7183 and 585, respectively. The number of cases in 2007 of primary TAA were 313; there were no cases of revision. The number of cases in 2017 of primary TAA were 986 and of revision were 108. The CAGR during this period was 28.6% for primary TAA and 44.6% for revision procedures. Incidences per 100,000 person- years in 2017 were 1.91 for primary TAA and 0.21 for revision procedures. The average cost paid by patients themselves was 813$ (19%) and by the national health insurance service was 3480$ (81%). Conclusion: Trends of primary TAA and revision procedures have been steadily rising in South Korea during the 11-year study period.

Objectives This study aims to review the effects of short- and long-term oral administration of postoperative corticosteroids in patients undergoing sialendoscopy for the treatment of obstructive sialadenitis due to ductal stenosis. Study design Prospective comparative study. Methods A prospective observational study was conducted at Manukau Surgical Center in Auckland, New Zealand, where patients undergoing sialendoscopic surgery for recurrent obstructive sialadenitis due to ductal stenoses were reviewed. Univariable and multivariable analysis, and also logistic regression were performed to identify variables correlated with the likelihood of the need for revision surgery for persistent or recurrent symptoms. Results In this study, sialendoscopy was performed in 142 patients: 162 parotid glands (86.6%) and 25 submandibular glands (13.4%). Postoperative oral steroids were prescribed for 48 patients (34%); 19 (13%) were prescribed for less than 7 days and 29 (20%) for more than 7 days. In total, 33 patients (23.2%) required a revision sialendoscopy during follow-up due to recurrence of symptoms. Oral steroids prescribed for more than 7 days after a sialendoscopy reduced the likelihood of a revision procedure by 93% when compared with patients who did not receive this medication, and by 96% when compared with patients who received steroids for less than 7 days. Conclusion The results showed that in our population oral administration of corticosteroids for more than 7 days after sialendoscopy for the treatment of recurrent obstructive sialadenitis due to ductal stenosis markedly reduced the need for later revision surgery. Routine use of corticosteroids for more than 7 days is recommended after sialendoscopy in patients with ductal stenosis. Level of evidence II Laryngoscope, 131:E1503-E1509, 2021.

We performed a retrospective analysis of the impact of using the International Classification of Diseases, Tenth Revision procedure coding system (ICD-10) or current procedural terminology (CPT) codes to calculate surgical site infection (SSI) rates. Denominators and SSI rates vary depending on the coding method used. The coding method used may influence interhospital performance comparisons.

CASE We report the case of a 44-year-old woman with previous anterior cruciate ligament (ACL) reconstruction 25 years ago in the right knee, who sustained a bucket-handle medial meniscus tear after pain and instability while pivoting during tennis. Magnetic resonance imaging demonstrated an intact but vertical and anterior ACL graft. A novel ACL retensioning procedure with suture augmentation (SA) was performed as the revision procedure. Excellent clinical outcomes and knee stability were obtained at both 17 and 36 months postoperatively. CONCLUSIONS In certain cases, ACL retensioning with SA may be performed as the revision procedure for unsuccessful primary ACL reconstruction.

Background and Objectives Expandable distal femur prostheses have become more popular over the last decades, but scientific data is limited. Methods A retrospective study was performed, including cases treated between 1986 and 2019 in 15 European referral centers for bone sarcomas. Results A total of 299 cases were included. Average follow-up was 80 months (range, 8-287 months). Mean patient age was 10 years. Most (80%) of the implants were noninvasive growers and a fixed hinge knee was used more often (64%) than a rotating hinge. Most prosthetic designs showed good (>80%) implant survival at 10 years, but repeat surgery was required for 63% of the patients. The most frequent reason for revision procedure was the completion of lengthening potential. Noninvasive expandable implants showed less risk of infection compared to invasive growers (11.8% vs 22.9% at 10 years). No difference in aseptic loosening was found between cemented and uncemented stems. Conclusions This study shows the increasing popularity of expandable distal femur prostheses, with overall good results for function and implant survival. However, repeat surgery is frequently required, especially in patients under the age of 10 years old. Infection is less frequent in noninvasive growers compared to implants that require invasive lengthening procedures.

OBJECTIVE The purpose of this study was to assess the influence of exposure to the open Bankart during residency and fellowship on the trend toward obsolescence of the procedure. Our hypothesis was that the open Bankart would be used with decreasing frequency and that this would be related to lack of exposure to the procedure during training. METHODS A survey consisting of 10 questions about their experience with the open Bankart procedure in residency, fellowship, and practice, as well as their current usage of it and other operations, was sent to members of the American Shoulder and Elbow Surgeons. Respondents were divided into groups based on the year of completion of training. RESULTS Statistical analysis of the responses revealed a notable trend of progressively diminished use of the open Bankart by those trained before 2000 compared with those completing training between 2001 and 2017. Ancillary findings included more surgeons using the open Bankart for revision cases than as a primary procedure and many using the Latarjet for patients with less than 15% or even no glenoid bone loss. CONCLUSION We concluded that a statistically notable trend of the decreasing use of the open Bankart was observed despite excellent reported outcomes and that its current role is most likely as a revision procedure. Lack of exposure to the operation in training is a major factor in its decline, and this decreasing exposure is self-perpetuating. LEVEL OF EVIDENCE Survey.

Sleeve gastrectomy is the most common bariatric procedure worldwide. Several studies report good short- and midterm results. However, recent studies report alarming long-term outcomes, in particular about the revision rate.The aim of this study is the assessment of the revisional rate after sleeve gastrectomy and the analysis of most common reasons for surgical conversion and early complications.This study is based on a national claims database comprehensive of all bariatric procedures performed in a 10-year period.The French Programme De Médicalisation des Systèmes d'Information database was used to identify all patients who underwent sleeve gastrectomy between 2008 and 2018. Codes for diagnoses and procedures were used to describe the reason for and the morbidity of revision surgeries. Multivariate Cox proportional hazard regression analysis was performed to compare the risk of having a revision procedure.During the analyzed period, a total of 224,718 sleeve gastrectomies were performed. The rate of revision surgery after sleeve gastrectomy was 4.7%, 7.5%, and 12.2%, at 5, 7, and 10 years post procedure, respectively. A history of gastric banding was associated with a higher risk of revision (hazard ratio, 2.81; 95% CI, 2.66-2.95; P.001). The most common revision procedure was gastric bypass (75.2%), followed by resleeve (18.7%). The main reasons for revision surgery were persistence of obesity (87.0%) and gastroesophageal reflux disease (5.2%). After revision surgery, we observed the following complications: 5.1% gastric leak, 18% bleeding, and reoperation rate of 6.4%.This study suggests that a large number of patients who initially underwent a sleeve gastrectomy will undergo a revisional surgery. This information should be considered in the initial choice of the bariatric procedure, and patients should be informed of the mid- and long-term risks.

Proximal humeral fractures are the third most common fracture in the elderly population (second to hip fractures and fractures of the distal radius), occurring at a frequency of approximately 105 per 100,000 individuals per year [1, 2]. As the general population ages and predicted life spans increase, the desire for procedures that restore joint function and maintain quality of life will become progressively relevant. Following this trend, it is likely the rate of arthroplasty for treatment of proximal humerus fractures—particularly in the elderly population—will likely rise in the decades to come [2]. For complicated fractures of the proximal humerus, both hemiarthroplasty (HA) and the reverse prosthesis have demonstrated promising short- and long-term results [3–10]. In the elderly population and situations involving complex fractures, each approach has exhibited superior outcomes in comparison to open reduction internal fixation (ORIF) and nonsurgical conservative management [11–16]. The reverse prosthesis in particular is selected as a revision procedure for failed HA, ORIF, and nonsurgical conservative management [17, 18].

Background The aim of this study was to investigate the surgical trends of primary total ankle arthroplasty (TAA) and revision procedure in Korea from 2007 to 2017 using national population-based data. Methods We reviewed the National Health Insurance data of Korea from 2007 to 2017. The data included diagnosis codes, procedure codes, prescriptions, medical costs, and other demographic data. Trends of primary diagnosis for primary TAA were evaluated. Annual trends and incidences per 100,000 person-years of primary TAA and revision procedures as well as compound annual growth rate (CAGR) during the study period were analysed. Surgical trends according to patients' age, hospital grades, and insurance systems were also evaluated. Results Primary diagnosis for primary TAA was mostly degenerative arthritis (6,501 cases; 90.5%). From 2007 to 2017, the total number of cases of primary TAA and revision procedures was 7,183 and 585, respectively. The number of cases in 2007 of primary TAA was 313; there were no cases of revision. The number of cases in 2017 of primary TAA were 986 and of revision were 108. The CAGR during this period was 28.6% for primary TAA and 44.6% for revision procedures. Incidences per 100,000 person-years in 2017 were 1.91 for primary TAA and 0.21 for revision procedures. The average cost paid by patients themselves was USD 813 (19%) and by the National Health Insurance Service was USD 3,480 (81%). Conclusion The incidence of primary TAA and revision procedures steadily increases in Korea during the 11-year study period., Graphical Abstract

Introduction: Surgical techniques for hallux valgus correction are constantly evolving. However, there is little data in the literature comparing the different techniques and methods of fixation. The aim of this study was to compare two variations of the Lapidus procedure with respect to the rate of complications, radiographic and functional outcomes. Methods: A retrospective review of 94 consecutive patients treated with a Lapidus fusion for hallux valgus correction between 2006 and 2017 was performed. In the first group, 33 patients underwent modeling arthrodesis between the first metatarsal base and the medial cuneiform, and between the base of the first and second metatarsals. In the second group, 61 patients underwent a fusion between the base of the first metatarsal and the medial cuneiform only. Results: In group 1, the rate of complications was 18% compared with 13% in group 2; of these, 10,5% required a revision procedure in group 1 versus 7,5% in group 2. The most common complications were nonhealing, partial recurrence of the deformity and loosened screws. In group 1, the first intermetatarsal angle and the hallux valgus angle were improved from an average of 18,3 degrees to 14 degrees and from 29 to 9,7 degrees, respectively. In group 2, the angles were improved from 16,1 to 9,1 degrees and from 31,1 to 9,1 degrees, respectively. The AOFAS score was improved from 44,5 to 94,9 in group 1 and from 35,8 to 91,32 in group 2. Conclusion: The Lapidus procedure with fusion of only the first metatarsal base and the medial cuneiform is safe, with a low rate of complications. In this modified procedure, the surgeon is required to optimize the congruency between the base of the first metatarsal and the medial cuneiform prior to fixation, which may conceivably explain the good results observed in this group.

Presented in this report is a complex revision case of a patellar tendon repair preceded by excess tendon excision to correct for recurrent patella alta deformity, in a workers’ compensation patient. The goal of this procedure was to alleviate this patient’s pain, to preserve his ability to function in his activities of daily living, and to allow him to return to work at some capacity. On postoperative radiographs, the revision procedure appeared to have successfully corrected this patient’s patella alta deformity. After an extended rehabilitation process, this patient had reached maximal medical improvement at 1-year follow-up. He displayed modest improvements in all PROs, including a clinically significant improvement in his short-form mental component score. Despite his functional capacity being still somewhat limited, this patient reported subjective satisfaction after this complicated salvage procedure.

Posterior shoulder instability is an uncommon and challenging cause of shoulder pain and dysfunction. Surgical management has less reliable results and higher failure rates compared with techniques for anterior shoulder instability. The presence of generalized ligamentous laxity further complicates options for surgical management. If primary capsulolabral repair fails, controversy exists as to the optimal revision procedure. This technical description and video present an arthroscopic technique for reconstruction of the posterior glenohumeral capsule with an acellular dermal allograft to treat posterior instability in a patient with Ehlers-Danlos syndrome and a previously failed posterior capsular plication.

Laparoscopic sleeve gastrectomy (LSG) is one of the most popular and effective bariatric surgical procedures worldwide. The effect of LSG is mostly dependent on the restrictive mechanism, which makes it more vulnerable to failure. Failing of bariatric procedure is not uncommon and occurs in 6% to 23%. In case of weight loss failure, there are no hard recommendations on the choice of the redo procedure. One of the most novel options, introduced in 2007, relatively simple to perform following LSG is single-anastomosis duodenoileal bypass. Herein we describe surgical technique and history of a patient with inadequate weight loss after laparoscopic sleeve gastrectomy, who underwent single-anastomosis duodenoileal bypass.

Background and purpose - The initial outcomes following metal-on-metal hip arthroplasty (MoMHA) revision surgery performed for adverse reactions to metal debris (ARMD) were poor. Furthermore, robust thresholds for performing ARMD revision are lacking. This article is the second of 2. The first article considered the various investigative modalities used during MoMHA patient surveillance (Matharu et al. 2018a ). The present article aims to provide a clinical update regarding ARMD revision surgery in MoMHA patients (hip resurfacing and large-diameter MoM total hip arthroplasty), with specific focus on the threshold for performing ARMD revision, the surgical strategy, and the outcomes following revision. Results and interpretation - The outcomes following ARMD revision surgery appear to have improved with time for several reasons, among them the introduction of regular patient surveillance and lowering of the threshold for performing revision. Furthermore, registry data suggest that outcomes following ARMD revision are influenced by modifiable factors (type of revision procedure and bearing surface implanted), meaning surgeons could potentially reduce failure rates. However, additional large multi-center studies are needed to develop robust thresholds for performing ARMD revision surgery, which will guide surgeons' treatment of MoMHA patients. The long-term systemic effects of metal ion exposure in patients with these implants must also be investigated, which will help establish whether there are any systemic reasons to recommend revision of MoMHAs.

STUDY DESIGN A retrospective review of a prospective database. OBJECTIVE The aim of this study was to determine cost and outcomes of revision cervical spine surgery. SUMMARY OF BACKGROUND DATA Revision rates for cervical spine surgery are steadily increasing. It is important to counsel patients on expected results following a revision procedure. However, outcomes and cost of these procedures are poorly defined in the literature. METHODS Patients undergoing revision cervical spine surgery at a single institution were included between October 2010 and January 2016 in a prospective registry database. Patients were divided into three cohorts depending on their etiology for revision, including recurrent disease, pseudoarthrosis, or adjacent segment disease. Patient-reported outcomes (PROs), including Neck Disability Index (NDI), EuroQol-5D (EQ-5D), modified Japanese Orthopaedic Association (mJOA) score, numeric rating scale-neck pain (NRS-NP), and numeric rating scale-arm pain (NRS-AP), were measured at baseline and 12 months following revision surgery. Mean costs at 12 months following revision surgery were also calculated. Satisfaction was determined by the NASS patient satisfaction index. Variables were compared using Student t test. RESULTS A total of 115 patients underwent cervical revision surgery for recurrent disease (n = 21), pseudoarthrosis (n = 45), and adjacent segment disease (n = 49). There was significant improvement in all patient-reported outcomes at 12 months following surgery regardless of etiology (P

AimsThe use of a noninvasive growing endoprosthesis in the management of primary bone tumours in children is well established. However, the efficacy of such a prosthesis in those requiring a revision procedure has yet to be established. The aim of this series was to present our results using extendable prostheses for the revision of previous endoprostheses.Patients and MethodsAll patients who had a noninvasive growing endoprosthesis inserted at the time of a revision procedure were identified from our database. A total of 21 patients (seven female patients, 14 male) with a mean age of 20.4 years (10 to 41) at the time of revision were included. The indications for revision were mechanical failure, trauma or infection with a residual leg-length discrepancy. The mean follow-up was 70 months (17 to 128). The mean shortening prior to revision was 44 mm (10 to 100). Lengthening was performed in all but one patient with a mean lengthening of 51 mm (5 to 140).ResultsThe mean residual leg length discrepancy at final follow-up of 15 mm (1 to 35). Two patients developed a deep periprosthetic infection, of whom one required amputation to eradicate the infection; the other required two-stage revision. Implant survival according to Henderson criteria was 86% at two years and 72% at five years. When considering revision for any cause (including revision of the growing prosthesis to a non-growing prosthesis), revision-free implant survival was 75% at two years, but reduced to 55% at five years.ConclusionOur experience indicates that revision surgery using a noninvasive growing endoprosthesis is a successful option for improving leg length discrepancy and should be considered in patients with significant leg-length discrepancy requiring a revision procedure.

Background: When anterior cruciate ligament (ACL) reconstruction fails, a revision procedure may be performed to improve knee function, correct instability, and allow return to activities. The results of revision ACL reconstruction have been reported to produce good but inferior patient-reported and objective outcomes compared with primary ACL reconstruction, but the degree to which this is the case varies widely among published studies and may be influenced by heterogeneity of patients, techniques, and endpoints assessed. For those reasons, a systematic review may provide important insights. Questions/purposes: In a systematic review, we asked: (1) What is the proportion of revision ACL reconstruction cumulative failures defined as rerupture or objective failure using prespecified clinical criteria at mean followup of at least 5 years? (2) What are the most common complications of revision ACL reconstruction? Methods: A systematic review was performed by searching PubMed/Medline, EMBASE, and CENTRAL. We included studies that reported the clinical evaluation of revision ACL reconstruction with Lachman test, pivot shift test, side-to-side difference with KT-1000/2000 arthrometer, and with a mean followup of at least 5 years. We excluded studies that incompletely reported these outcomes, that reported only reruptures, or that were not in the English language. Extracted data included the number of graft reruptures and objective clinical failure, defined as a knee that met one of the following endpoints: Lachman test Grade II to III, pivot shift Grade II to III, KT-1000/2000 > 5-mm difference, or International Knee Documentation Committee Grade C or D. For each study, we determined the proportion of patients who had experienced a rupture of the revision ACL graft as well as the proportion of patients who met one or more of our clinical failure endpoints. Those proportions were summed for each study to generate a percentage of patients who met our definition of cumulative failure. Complications and reoperations were recorded but not pooled as a result of inconsistency of reporting and heterogeneity of populations across the included studies. Of the 663 screened studies, 15 articles were included in the systematic review. Because one study reported two separate groups of patients with different treatments, 16 case series were considered in the evaluation. Results: The proportion of reruptures (range, 0%–25%) was > 5% in only four of 16 series and > 10% in only one of them. The objective clinical failures (range, 0%–82%) was > 5% in 15 of 16 series and > 10% in 12 of them. The proportion exceeded 20% in five of 16 series. The cumulative failures (range, 0%–83%) was > 5% in all except one series and > 10% in 12 of 16 series; five series had a cumulative failure proportion > 20%. The most frequent complications were knee stiffness and anterior knee pain, whereas reoperations were primarily débridement and meniscectomies. Conclusions: Considering rerupture alone as a failure endpoint in patients who have undergone revision ACL reconstruction likely underestimates the real failure rate, because the percentage of failures noticeably increases when objective criteria are also considered. Whether patient-reported and subjective scores evaluating knee function, level of activity, satisfaction, and pain might also contribute to the definition of failure may be the focus of future studies. Level of Evidence: Level IV, therapeutic study.

Purpose: We describe and categorize complications using the Clavien-Dindo classification system in patients who underwent vaginal mesh excision surgery.Materials and Methods: With institutional review board approval we retrospectively reviewed the records of 277 patients who underwent vaginal mesh extraction between 2007 and 2015 at a single institution. Surgical complications were stratified using the Clavien-Dindo classification system. Complications were perioperative (prior to discharge) or postoperative (within 90 days). Indications for initial mesh placement, mesh revision procedure, time to resolution and medical comorbidities were assessed.Results: Of the 277 patients 47.3% had at least 1 surgical complication, including multiple complications in 7.2%. A total of 155 complications were identified, which were grade II in 49.0% of cases, grade I in 25.8%, grade IIIb in 18.7%, grade IIIa in 5.2% and grade IVa in 1.3%. No grade IVb or V complications were identified. The indication for initial mesh pl...

Summary Objective To identify: 1. The percentage of bariatric procedures that are revisions; 2. What proportion of bariatric revision procedures in public hospitals are for patients whose primary weight loss procedure occurred in a private hospital; 3. The age, sex and level of socioeconomic disadvantage of patients needing revisions. Methods An analysis of patient level admission data from the Integrated South Australian Activity Collection (ISAAC) was performed. Data were collected on all revisions for weight loss related procedures at all South Australian public and private hospitals, between 2000–2015 using the ISAAC codes for revision procedures. Results 12,606 bariatric procedures occurred in hospitals; ∼27% of which represent a revision (n = 3366). Of these revisions, ∼82% occurred in a private hospital (n = 2771), and ∼18% occurred in a public hospital (n = 595). Of the 595 revisions in a public hospital, 51% of patients had their original bariatric procedure performed in a private hospital. The majority of patients who had a revision procedure are female (≥82%) with a mean age of ∼45. Individuals from the lowest 2 IRSD quintiles were over-represented for public hospital revisions and primary bariatric procedures. Conclusion Further investigation is needed to identify: 1. Why 27% of bariatric procedures are revisions; 2. Why at least 51% of revisions in public hospitals are on patients whose original primary bariatric procedure was done in a private hospital; 3. The impact that revision procedures in public hospitals, particularly for originally private weight loss procedures, is having on public hospital wait times; 4. The impact of socioeconomic disadvantage on weight loss procedure outcomes.
