RESUMO
BACKGROUND: Loss of shoulder range of motion (ROM) is common after surgical management of anterior shoulder instability; however, it remains unclear to what degree this is related to their injury. AIM: The purpose of this study was to compare passive shoulder ROM in patients with ASI to a normal contralateral shoulder. METHODS: A total of 121 patients undergoing stabilization surgery were prospectively enrolled. Preoperative advanced imaging was used to assess for glenoid bone loss and the presence of off-track Hill-Sachs lesions. Passive ROM was measured in both shoulders while under anaesthesia prior to surgery. RESULTS: In all directions, there was a significant loss of ROM in shoulders with instability. Regression analysis showed that neither a glenoid bone defect nor greater glenoid bone loss were associated with a loss of ROM in any plane. The presence of a Hill-Sachs lesion was significantly associated with a loss of external rotation, while off-track lesions were associated with a loss of ROM in all planes (p < 0.05). CONCLUSION: Patients with anterior shoulder instability lost motion in all directions, with a profound loss of external rotation. The presence of a glenoid bone defect nor greater bone loss did not reliably predict a loss of range of motion. A Hill-Sachs lesion was predictive of a loss of external rotation, while an off-track lesion was predictive of a loss of range in all directions.
RESUMO
Background: Acromioclavicular joint (ACJ) injury is a common orthopaedic condition accounting for over 40 % of all shoulder injuries. The purpose of this study is to assess the research trends and characteristics of the top 50 cited articles on ACJ instability. Methods: A systematic search was conducted in Web of Science to identify articles primarily related to ACJ injury or instability. Characteristics including citation number, country of origin, journal and institution of publication, impact factor, authorship, level of evidence, patient demographics, and study type were analyzed and recorded. Results: Research output on ACJ instability has been steadily increasing, with the top 50 cited studies predominantly presenting Level IV evidence. These studies primarily focused on treatment outcomes which included predominantly male patients and exhibited a large variation in citation counts. The American Journal of Sports Medicine was the most productive journal, and the USA was the most productive nation. Conclusion: There is an increasing number of publications in the ACJ instability literature, primarily concentrated in a few institutions and journals, and focusing mainly on treatment outcomes. A significant portion of these publications are of low scientific quality, and there is a notable lack of research on outcomes for females.
RESUMO
PURPOSE: The purpose of this study was to evaluate glenohumeral morphological features on a magnetic resonance arthrogram (MRA) to determine risk factors for recurrence of anterior shoulder instability following arthroscopic Bankart repair (ABR). METHODS: A retrospective review of patients who underwent ABR between 2012 and 2017 was performed to identify patients who had recurrence of instability following stabilisation (Group 1). These were pair-matched in a 2:1 ratio for age, gender and sport with a control (Group 2) who underwent ABR without recurrence. Preoperative MRAs were evaluated for risk factors for recurrence, with glenoid bone loss and Hill-Sachs lesions also measured. Multilinear and multilogistic regression models were used to evaluate factors affecting recurrence. RESULTS: Overall, 72 patients were included in this study, including 48 patients without recurrence and 24 patients with recurrent instability. There was a significant difference between the two groups in mean glenoid bone loss (Group 1: 7.3% vs. Group 2: 5.7%, p < 0.0001) and the rate of off-track Hill-Sachs lesions (Group 1: 20.8% vs. Group 2: 0%, p = 0.0003). Of the variables analysed in logistic regression, increased glenoid anteversion (p = 0.02), acromioclavicular (AC) degeneration (p = 0.03) and increased Hill-Sachs width were associated with increased risk of failure. Increased chondral version (p = 0.01) and humeral head diameter in the anteriorposterior view were found to be protective and associated with a greater likelihood of success. CONCLUSION: Glenoid anteversion was a risk factor for recurrent instability, whereas increased chondral version and humeral head diameter were associated with higher rates of success following ABR. Glenoid bone loss, presence of an off-track Hill-Sachs lesion, increased Hill-Sachs width and AC degeneration were also associated with failure. These findings should be used by surgeons to stratify risk for recurrence following ABR. LEVEL OF EVIDENCE: Level III.

Background: To systematically review the literature to evaluate the outcomes following an open Latarjet (OL) procedure at a minimum 15-year follow-up. Methods: Two independent reviewers performed a literature search using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using 3 databases. Only studies reporting outcomes of OL procedure with a minimum of 15 years of follow-up were included. Results: Nine studies composed of 326 shoulders (78.2% males) in 313 patients were included (average age 26.9 ± 3.2 years (15-58)), with a mean follow-up of 271.9 ± 69.2 months (180-420) At a minimum 15-year follow-up, 93.5% (286 of 306) patients reported being satisfied with their OL procedure, whilst 86.8% (177 of 204) reported good/excellent outcomes at final follow-up. All nine of the included studies reported an overall rate of recurrent instability was 7.7%, with re-dislocations and subluxation at 3.4% and 5.8%, respectively. The rate of surgical revision was 5.15%; 3.5% of cases were revised for recurrent instability. Instability arthropathy was reported across all included studies as 41.0%. Conclusion: The OL procedure results in satisfactory clinical outcomes, low rates of recurrent instability and surgical revision at a minimum 15-year follow-up. Although high levels of radiological instability arthropathy and residual pain are found over the same period, these appear stable from a minimum of 10-year follow-up data. Level of Evidence: IV; a systematic review of all levels of evidence.
RESUMO
Background: Excellent short-term outcomes after reverse shoulder arthroplasty (RSA) have been reported, but longer term outcomes in the existing literature are sparse and vary widely. The purpose of this study is to systematically assess the existing literature to quantify functional outcomes and complication rates after RSA at a minimum of five years of follow-up. Methods: A Preferred Reporting Items for Systematic Reviews and Meta-analyses-compliant systematic literature search of the PubMed and Embase databases was undertaken. Studies reporting outcomes after primary RSA for nontrauma-related indications with a minimum of 5-year follow-up were included. Results: Overall, 20 studies satisfied all inclusion criteria. This represented 1591 shoulders in 1556 patients (32.1% males), with a mean age of 70.2 ± 5.0 years and mean follow-up of 8.8 years, or 106.2 ± 30.1 months (60-243). At final follow-up, the mean reported Constant Murley score was 62.1 ± 5.0 (49.0-83.0). The mean adjusted Constant Murley score was 83.5 ± 12.5 (58-111.9). The mean American Shoulder and Elbow Surgeons score was 81.8 ± 4.6, while the mean subjective shoulder value was 74.6 ± 6.4. Overall, 88% of patients rated their satisfaction as either good or very good. The range of active forward flexion, abduction, external, and internal rotation were respectively, 126° ± 13°, 106° ± 11°, 22° ± 11°, and 6° ± 2°. The overall rate of revision surgery was 4.9% (0%-45.5%). Regarding complications, the rate of prosthetic joint infection was 4.3% (0%-26.7%), shoulder dislocation was 3.7% (0%-20.4%), and acromial fracture was 2.0% (0%-8.8%). At final follow-up, 30.9% of shoulders had some degree of scapular notching. Conclusion: This systematic review shows that RSA results in high satisfaction rates, good clinical outcomes, as well as modest complication and revision rates at minimum 5-year follow-up.
RESUMO
BACKGROUND: Acromioclavicular (AC) joint dislocation is a common clinical problem among young and athletic populations. Surgical management is widely used for high-grade dislocations (Rockwood III-VI) and in high-demand athletes at high risk of recurrence. PURPOSE: To systematically review the evidence in the literature to ascertain the rate and timing of return to play (RTP) and the availability of specific criteria for safe RTP after surgical treatment for AC joint dislocation. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic literature search based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted in the PubMed database. Clinical studies were eligible for inclusion if they reported on RTP after surgical treatment for AC joint dislocation. Statistical analysis was performed with SPSS. RESULTS: We found 120 studies including 4327 cases meeting our inclusion criteria. The majority of patients were male (80.2%), with a mean age of 37.2 years (range, 15-85) and a mean follow-up of 34.5 months. Most were recreational athletes (79%), and the most common sport was cycling. The overall rate of RTP was 91.5%, with 85.6% returning to the same level of play. Among collision athletes, the rate of RTP was 97.3%, with 97.2% returning to the same level of play. In overhead athletes, the rate of RTP was 97.1%, with 79.2% returning to the same level of play. The mean time to RTP was 5.7 months (range, 1.5-15). Specific RTP criteria were reported in the majority of the studies (83.3%); time to return to play was the most commonly reported item (83.3%). Type III Rockwood injuries had the highest RTP rate at 98.7% and the earliest RTP at 4.9 months. Among the different surgical techniques, Kirschner wire fixation had the highest rate of RTP at 98.5%, while isolated graft reconstruction had the earliest RTP at 3.6 months. CONCLUSION: The overall rate of RTP was reportedly high after surgical treatment for AC joint dislocation, with the majority of patients returning to their preinjury levels of sport. There is a lack of consensus in the literature for what constitutes a safe RTP, with further focus on this topic required in future studies.

PURPOSE: To assess the quality and level of evidence of studies reporting on Bankart repair for anterior shoulder instability. METHODS: A search was performed using the PubMed/Medline database for all studies that reported clinical outcomes on Bankart repair for anterior shoulder instability. The search term "Bankart repair" with all results were analyzed via strict inclusion and exclusion criteria. Two independent investigators scored each included study based on the 10 criteria of the Modified Coleman Methodology Score (CMS) out of 100 and gave each study a score out of 25 based on the Anterior Shoulder Instability (ASI) Methodology criteria. RESULTS: Two hundred sixty-six studies were included in the analysis and encompassed a total of 19,156 patients and 19,317 surgical procedures for Bankart repair for shoulder instability. Overall, 81.6% of studies were Level III or IV evidence. The mean CMS score for the studies was 55.3 out of 100, and the mean ASI Methodology score for the studies was 12.1 out of 25. Weaknesses in the studies were identified in sample size, description of preoperative investigations and diagnoses, reporting of mean glenoid bone loss, nonsubjective clinical outcome reporting, and description of associated pathologies. CONCLUSIONS: A large proportion of studies reporting the clinical outcomes of Bankart repair for anterior shoulder instability are of low methodological quality and have a low level of evidence. CLINICAL RELEVANCE: This study emphasizes need for greater reporting of many variables such as body mass index, mean glenoid bone loss, and patient-reported outcomes and provides a framework for future studies reporting.

PURPOSE: To evaluate return to play (RTP), clinical outcomes, and recurrence rates in collision athletes 20 years of age and younger who underwent open Latarjet for anterior shoulder instability. METHODS: A retrospective review of collision athletes 20 years of age and younger, who underwent an open Latarjet procedure by a single surgeon between the years of 2010-2020 was carried out. Inclusion criteria were 1) collision athlete, 2) underwent open Latarjet procedure, 3) 16-20 years old, and 4) minimum 24-month follow-up. Exclusion criteria were 1) other pathology of the ipsilateral shoulder and 2) noncollision athlete. Rate of RTP, time to RTP, rate of return to preinjury level, the Shoulder Instability Return to Sport after Injury score (SIRSI) score, Subjective Shoulder Value (SSV), visual analogue scale (VAS) scores, and recurrence events were recorded. Quantitative statistical analysis was carried out. RESULTS: The study included 105 male collision athletes with a mean age of 18.6 ± 1.0 years (range: 17-20). The mean follow-up for patients was 36 ± 26.2 months. A total of 93 (88.6%) RTP at a mean time of 6.3 ± 2.2 months, with 73 (69.5%) returning to their preinjury level of participation. The mean SIRSI score was 69.2 ± 21.8, the mean VAS score was 2.3 ± 2.1, and the mean SSV score was 84.1 ± 16.8. Five patients (4.8%) redislocated their shoulder, with 4 of these requiring a further surgery (3.8%). Two patients (1.9%) reported incidents of subluxation. CONCLUSIONS: The open Latarjet procedure in young collision athletes results in high rates of RTP, excellent functional outcomes and low recurrence rates at mid-term follow-up. Additionally, complication rates are low in this cohort. LEVEL OF EVIDENCE: Level IV, case series.

PURPOSE: The primary aim was to identify and quantify differences in interlimb asymmetry magnitudes across a battery of upper extremity strength and performance tests at 4 and 6 months after glenohumeral joint stabilization surgery shoulder stabilization in contact and collision athletes compared with an un-injured group. A secondary aim was to investigate if identified asymmetry magnitudes changed from 4 to 6 months after glenohumeral joint stabilization surgery. The third aim was to explore associations within the different performance and strength variables. METHODS: Fifty-six male contact and collision sport athletes who had had undergone unilateral glenohumeral joint stabilization were tested at 4 and 6 months after surgery. An un-injured control group ( n = 39 for upper extremity performance tests, n = 47 for isokinetic dynamometry) were tested on a single occasion. Three upper extremity force platform-based performance tests and angle-specific concentric internal and external isokinetic shoulder rotational strength were assessed, and interlimb asymmetries were compared between the two groups. RESULTS: At 4 months after surgery, the glenohumeral joint stabilization group demonstrated significantly higher absolute interlimb asymmetry values than the un-injured group for almost all the performance test variables. In the ballistic upper-body performance tests, the glenohumeral joint stabilization group achieved only half the body elevation reached by the un-injured (counter-movement push-up jump height ( η2 = 0.50) and press-jump jump height ( η2 = 0.39)). At 6 months after surgery, absolute interlimb asymmetries reduced for the performance test variables, but some asymmetry persisted. The glenohumeral joint stabilization group had significantly greater absolute interlimb asymmetries for five out the eight isokinetic variables. CONCLUSIONS: Contact and collision athletes who may be cleared to return to sport at 4 to 6 months after glenohumeral joint stabilization surgery shoulder stabilization continue to demonstrate upper limb strength and performance deficits when compared with their un-injured limb and their un-injured counterparts.

IMPORTANCE: As reverse total shoulder arthroplasty (RTSA) has become an increasingly common procedure, rates of post-operative complications leading to potential hospital readmission are of greater importance. No previous systematic reviews have focused exclusively on post-operative complications and mortality rates at 90 days post RTSA. OBJECTIVES: The purpose of this study was to review complication, readmission, and mortality rates within 90 days post RTSA. EVIDENCE REVIEW: Two independent reviewers performed a literature search using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines using PubMed, Embase, and Web of Science databases. Only studies reporting on outcomes of RTSA at 90-days follow-up specifically were considered for inclusion. FINDINGS: Our search included 79,037 shoulders (62.1 â% female) from a total of 15 studies with an average age of 72.4 â± â5.8 years. The overall 90-day re-admission rates were reported in nine studies as 6.1 â% (4205/69,127) following RTSA. Additionally, a total of five studies reported the overall 90-day mortality rate as 1.1 â% (19/1733). The overall pooled rate of medical complications was 3.9 â% (2998/77,826) as reported in 13 studies, at 90-days post-RTSA, with the occurrence of anaemia being the most commonly reported outcomes as 2.9 â% (1013/34,385) in six studies. The overall rate of surgical complications was 1.1 â% reported in 13 studies (1327/77,826), with the pooled rate of surgical revisions of 1.5 â% (607/40,563) at 90-days follow-up. A total of 8, 5, and 3 studies reported rates of dislocation, requirement for closed reduction and glenoid loosening as 0.9 â% (344/37,995), 0.6 â% (7/1180), and 0.3 â% (30/9115) respectively at 90-days following RTSA. CONCLUSIONS AND RELEVANCE: This study established that the overall rates of mortality and medical and surgical complications are low in the short-term following RTSA, with only 6 â% of patients requiring re-admission in the first 90 days. LEVEL OF EVIDENCE: IV - Systematic Review of all levels of evidence.

Introduction: A recent study based on a large osteological collection reported an association between clavicle fractures and osteoarthritis of the glenohumeral joint. No clinical study has yet addressed this potential association. Other radiographic parameters such as the critical shoulder angle have been associated with the risk of glenohumeral joint osteoarthritis. The primary outcome of this study was to determine if there is an association between glenohumeral joint arthritis and clavicle fractures. The secondary outcome was to determine the association between critical shoulder angle and glenohumeral joint arthritis in our patient cohort. Methods: We retrospectively analysed 572 consecutive shoulder arthroplasty surgeries. Osteoarthritis was the indication for 343 shoulder arthroplasties. 229 shoulder arthroplasties were performed due to another diagnosis such as trauma or fracture, cuff arthropathy, or revision surgery. Three fellowship trained consultant shoulder surgeons assessed the pre- and post-operative radiographs of all patients. Results: A clavicle fracture was suspected in 5/343 (1.5 %) shoulder arthroplasties performed due to osteoarthritis and 5/229 (2.1 %) shoulder arthroplasties performed for another diagnosis. Interobserver variability was assessed using a Fisher Exact test and showed no significant relationship between osteoarthritis and a fracture of the clavicle (p = 0.531). Critical shoulder angle results correlated with the previously published literature regarding critical shoulder angle and osteoarthritis and rotator cuff arthropathy. Conclusion: Clavicle fractures were not associated with glenohumeral osteoarthritis in our patient cohort of shoulder arthroplasty patients. Critical shoulder angle results were consistent with published literature. Further research in the form of prospective long term studies are needed to establish if any association exists between clavicle fractures and osteoarthritis of the glenohumeral joint. Level of evidence: Level III. Retrospective analysis.
RESUMO
Background: Immediate post-operative plain film radiograph x-rays in PACU following open Latarjet procedure are often ordered as routine. However, such radiographs utilize institutional cost and time, whilst potentially exposing patients to often-unnecessary additional radiation. This study sought to evaluate whether routine immediate post-operative radiographs following uncomplicated open Latarjet procedures impacted clinical decision-making in our institution. Methods: From 2017 to 2020, patients who underwent open Latarjet procedure by one of four fellowship-trained upper limb surgeons at a single institution were included in this study. Post-operative radiographs taken immediately in PACU were reviewed to determine if any reported radiographic findings impacted on clinical decision-making in the immediate post-operative setting. SPSS was used for descriptive statistics. Results: A total of 337 patients underwent an X-ray in PACU immediate after uncomplicated open Latarjet procedure. Overall, 98.5% were male (n = 332), the mean patient age of included patients was 22.9 ± 4.2 years. No patient had an abnormal finding on their post-operative x-ray. Two patients returned to the operating room in the immediate post-operative period, both requiring washout and debridement due to haemtoma or superficial wound infection. Conclusion: The findings of this study suggest that the use of post-operative plain films in PACU following open Latarjet procedure remains a costly use of resources, with little ultimate impact on clinical decision making in the short-term post-operatively. Level of Evidence: IV - Institutional Case Series of Consecutive Patients.
RESUMO
BACKGROUND: The purpose of this study was to systematically review the literature to evaluate the effect of pre-existing mood disorders on patient-reported outcomes after arthroscopic rotator cuff repair (ARCR). METHODS: Two independent reviewers performed a literature search using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines using PubMed, Embase, Cochrane Library, and Scopus databases. Only studies which grouped as either having a pre-existing mood disorder (namely anxiety and/or depression) or not and evaluated patient-reported outcomes following ARCR procedures were considered for inclusion. Meta-analysis was performed on outcomes using RevMan, with a p-value <0.05 being deemed statistically significant. RESULTS: Our search found 8 studies including 1,166 shoulders (58.9% males), with an average age of 57.7 ± 3.2 years (21-81) and mean follow-up of 20.8 ± 16.7 months (3-77) which met our inclusion criteria. There were a total of 262 patients (22.5%; mean age 59.9 ± 1.4 years) with pre-existing anxiety and/or depression and 904 patients (77.5%; mean age 59.7 ± 1.7 years) in the control group who underwent ARCR, respectively. Meta-analysis found significantly lower American Shoulder and Elbow Surgeons scores as well as Simple Shoulder Test scores in patients with pre-existing anxiety and/or depression when compared with a control (mean difference [MD] -7.92 [-9.45, -6.40], p < 0.0001, I2 = 0%; MD -1.56 [-2.54, -0.59], p = 0.002, I2 = 80%, respectively) In addition, meta-analysis demonstrated significantly higher Visual Analog Scale scores for pain in patients with pre-existing anxiety and/or depression when compared with a control (MD 0.70 [0.02, 1.38], p = 0.04, I2 = 71%). Furthermore, meta-analysis performed found that ARCR resulted in significant changes in the rates of reported anxiety and/or depression in patients with pre-existing anxiety and/or depression (MD 4.06[-2.47, 6.68], p < 0.0001, I2 = 0%). CONCLUSION: Our review found that patients with pre-existing mood disorders were significantly more likely to report higher rates of postoperative pain and poorer functional outcomes following ARCR procedures, when compared with controls without mood disorders. Therefore, the presence of pre-existing anxiety and/or depression warrants consideration in the management paradigm for patients with rotator cuff tears. More optimistically, however, ARCR resulted in significant improvements in anxiety and/or depressive symptoms postoperatively. LEVEL OF EVIDENCE: Level III; systematic review of retrospective comparative studies. See Instructions for Authors for a complete description of levels of evidence.

Purpose: To assess and compare glenoid version in patients with anterior shoulder instability (ASI), posterior shoulder instability (PSI), and a control group. Methods: The operative notes of all patients that had undergone arthroscopic shoulder instability repair between January 2017 and May 2022 were retrospectively reviewed. Magnetic resonance imaging scans were then analyzed, and glenoid version was measured by a single blinded observer. A P value <.05 was considered statistically significant. Results: There were 100 patients included in the ASI group, 65 in PSI group, and 100 in the control group. The mean glenoid versions for the ASI group were -16°, -9.1°, and -9.2° for the vault version, simplified vault version, and chondrolabral version, respectively. The mean glenoid versions for the PSI group were -21°, -13.4°, and -16.6° for the vault version, simplified vault version, and chondrolabral version, respectively. The mean versions for the control group were -17.8°, -9.5°, and -9.8° for the vault version, simplified vault version and chondrolabral version, respectively. ANOVA testing and post hoc comparisons revealed the PSI group to be significantly more retroverted than both other groups P < .001. The ASI group's degree of glenoid version was not significantly different to that of the control P = .009. Conclusion: Patients with PSI have a higher degree of retroversion in comparison to those with ASI and control. There is no significant difference in glenoid version among patients with ASI when compared with control. Level of Evidence: Level III, retrospective comparative study.
RESUMO
OBJECTIVES: The purpose of this study is to systematically review the comparative studies in the literature to compare the outcomes of the Latarjet procedure in the setting of a previously failed Bankart repair versus those undergoing the Latarjet procedure as a primary surgery for anterior shoulder instability. METHODS: A systematic search in Pubmed, EMBASE, and The Cochrane Library databases was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Cohort studies comparing outcomes in the Latarjet procedure as a primary surgery versus the Latarjet procedure in the setting of a previously failed Bankart repair were included. RESULTS: Ten studies with 1913 patients were included. There was a significantly lower rate of recurrent instability in those with a Latarjet procedure as a primary surgery (4.8% vs 12.1%, p â= â0.007). There was also a significantly lower rate of complications with the Latarjet procedure as a primary surgery (6.2% vs 10.2%, p â= â0.03). Furthermore, there was a significant difference in the rate of revision surgery in favour of the Latarjet procedure as a primary surgery (4.8% vs 10.9%, p â= â0.02). However, there were similar rates of redislocations (2.8% vs 3.4%, p â= â0.82) and return to play (67.7% vs 78.5%, p â= â0.30) between the two cohorts. CONCLUSION: This study found that the Latarjet procedure as a revision procedure for a previously failed Bankart repair resulted in higher rates of complications, recurrent instability, and revisions than the Latarjet procedure performed as a primary procedure. LEVEL OF EVIDENCE: Level III, Systematic Review & Meta-Analysis of Level III studies.

Background: Anterior shoulder instability causes considerable patient morbidity and the volume of shoulder stabilization surgery being performed annually is rising. Despite stabilization surgery, instability arthropathy in the long-term may arise requiring consideration of shoulder arthroplasty. This study evaluated the outcomes of shoulder arthroplasty following previous stabilization surgery with their associated changes in bony anatomy or soft tissue structure. Methods: A systematic review was performed as per Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines to identify all studies reporting outcomes of shoulder arthroplasty in the setting of previous stabilization surgery. Studies of >10 patients with a minimum of 24 months follow-up were included. Results: Overall, 377 shoulder arthroplasties composed of 247 anatomical total shoulder arthroplasties (aTSAs), 102 reverse total shoulder arthroplasties (RTSAs), and 28 hemiarthroplasties (HAs) were reported across 14 included studies at mean age 55.4 years, with 203 compared to 451 control shoulders in 7 matched case-control studies. The mean interval from arthroplasty to stabilization procedure was 19.7 years, with 27.2% of patients having undergone multiple procedures and 39.5% bone transfer procedures. Improvements in patient outcomes were observed both for patients who had underwent aTSA or RTSA, with the American Shoulder and Elbow Surgeons score the most commonly used scoring system. Across matched studies comparing to control, large improvements in American Shoulder and Elbow Surgeons were seen for both aTSA and RTSA implants, 38.1-80.5 and 34.9-82.3, which compared to control groups 38.0-85.5 and 35.5-82.3, respectively. There were differences observed in complication profiles between aTSA and RTSA procedures, with lower revision rates in the short-term to medium-term for RTSA implants in present literature. A significantly higher rate of aTSA revision was observed compared to matched control patients undergoing aTSA for primary osteoarthritis without previous stabilization surgery, 9.4% (13/139) vs. 4.1% (11/269) (P = .044). Aseptic loosening posed a particular challenge in the aTSA group, with significantly higher rates of 5.0% (7/139 f = 54.6 months) compared to control 0.74% (2/269 f = 49.1 months, P = .0088). No significant difference in infection rate was observed between matched study and control groups, 1.5% vs. 2.2% (P = .76). Conclusion: Shoulder arthroplasty may improve functional outcomes for patients experiencing instability arthropathy with a history of stabilization surgery. Careful consideration of potential complications is warranted both in surgical planning and patient counselling given the altered anatomy and biomechanics, with significantly higher revision and loosening rates observed following aTSA compared to control.
RESUMO
Reverse shoulder arthroplasty (RSA) is used in the treatment of traumatic and arthritic pathologies, with expanding clinical indications and as a result there has been an increase in clinical research on the topic. The purpose of this study was to examine the statistical fragility of randomized control trials (RCTs) reporting outcomes from RSA. A systematic search was undertaken to find RCTs investigating RSA. The Fragility Index (FI) was calculated using Fisher's exact test, by sequentially altering the number of events until there was a reversal of significance. The Fragility Quotient (FQ) was calculated by dividing the FI by the trial population. Each trial was assigned an overall FI and FQ calculated as the median result of its reported findings. Overall, 19 RCTs warranted inclusion in the review, representing 1146 patients, of which 41.2% were male, with a mean age of 74.2 ± 4.3 years and mean follow-up of 22.1 ± 9.9 months. The median RCT population was 59, with a median of 9 patients lost to follow-up. The median FI was 4.5, and median FQ was 0.083, indicating more patients did not complete the trial than the number of outcomes which would have to change to reverse the finding of significance. This review found that the RCT evidence for RSA management may be vulnerable to statistical fragility, with a handful of events required to reverse a finding of significance.
RESUMO
PURPOSE: To study the literature to evaluate the functional outcomes, radiologic outcomes, and revision rates following arthroscopic rotator cuff repair (ARCR) at a minimum of 10-years follow-up. METHODS: Two independent reviewers performed a literature search of PubMed, Embase, and Scopus using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Only studies reporting on outcomes of ARCR with a minimum 10-year follow-up were considered for inclusion. Patient demographics, satisfaction, and clinical, radiologic, and surgical outcomes were evaluated. RESULTS: Our search found 9 studies including 455 shoulders in 448 patients (51.6% male patients), with age at time of surgery ranging from 45 to 90 years met our inclusion criteria. Overall follow-up ranged from 10 to 18 years. At final follow-up, the ranges of American Shoulder & Elbow Surgeons, age- and sex-adjusted Constant-Morley, and University of California Los Angeles scores were reported in 5, 6, and 3 studies, respectively, as 79.4 to 93.2, 73.2 to 94, and 26.5 to 33, respectively. Of the included studies, satisfaction rates varied in 6 studies from 85.7% to 100% in the long-term. Additionally, the overall radiologic retear rate ranged from 9.5% to 63.2%. The overall surgical revision rates ranged in 6 studies from 3.8% to 15.4%, with from 0% to 6.7% requiring revision ARCR and from 1.0% to 3.6% requiring revision subacromial decompression in 6 and 2 studies, respectively, at minimum 10-years' follow-up. CONCLUSIONS: In this study, we found that ARCR results in high rates of patient satisfaction, satisfactory clinical outcomes with respect to patient-reported functional outcomes and range of motion, and low revision rates at minimum 10-years' follow-up. However, an overall 30% retear rate was observed in asymptomatic patients. LEVEL OF EVIDENCE: Level IV, systematic review of Level II-IV studies.

BACKGROUND: Debate centering on the management of anterior shoulder instability (ASI) in recent years has led to many randomized controlled trials (RCTs) being published on the topic. The fragility index (FI) has subsequently emerged as a novel method of assessing significant findings reported in RCTs, particularly those with small sample sizes. PURPOSE: To evaluate the FI of statistically significant findings in RCTs that reported the outcomes of management strategies of patients with ASI. STUDY DESIGN: Systematic review; Level of evidence, 1. METHODS: Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 2 independent reviewers performed a systematic review of RCTs focusing on the outcomes of management strategies of patients with ASI. There were 3 main categories of RCTs included: (1) nonoperative management in internal rotation (IR) versus external rotation (ER), (2) nonoperative management versus a surgical intervention, and (3) surgical management with arthroscopic Bankart repair versus open Bankart repair. The Fisher exact test was utilized to calculate the FI for the reversal of statistical significance in all statistically significant dichotomous outcomes. RESULTS: A total of 21 RCTs were included, including 1589 shoulders (mean age, 29.4 years) with a mean follow-up of 26.8 months. There were 10 RCTs (831 shoulders) that reported outcomes after the nonoperative management of ASI in IR versus ER, with a mean FI of 6.8. There were 5 RCTs (324 shoulders) that reported outcomes comparing the nonoperative and operative management of ASI, with a mean FI of 3.5. There were 6 RCTs (434 shoulders) that reported outcomes after the operative management of ASI with either arthroscopic Bankart repair or open Bankart repair, with a mean FI of 9.6. CONCLUSION: The overall FI of RCTs reporting the outcomes of management strategies for patients with ASI was high, suggesting a moderate fragility of statistically significant outcomes including recurrence, revision stabilization, and return to play.

BACKGROUND: The purpose of this study was to systematically review the literature to ascertain the clinical outcomes of the open Latarjet (OL) procedure using either a subscapularis-split (SS) or subscapularis tenotomy (ST) via a deltopectoral (DP) approach. METHODS: Two independent reviewers performed a literature search using the PubMed, Embase, and Scopus databases according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Only studies reporting on outcomes of the OL procedure via a DP approach comparing both SS and ST were considered for inclusion. Meta-analysis to compare clinical outcomes was performed using RevMan software. RESULTS: Our search found 5 studies that met our inclusion criteria, including 615 shoulders (80.8% male patients), with an average age of 27.8 ± 12.6 years (range, 15-79 years) and mean follow-up period of 50.1 ± 29.4 months (range, 12-180 months). A total of 410 shoulders and 205 shoulders underwent the OL procedure via a DP approach using the ST technique and the SS technique, respectively, with both techniques resulting in significant increases in the Rowe score postoperatively (P < .0001 for both). Additionally, significantly higher postoperative Constant scores were observed in patients who underwent the OL procedure via an SS technique vs. those in the ST group (91.8 ± 7.2 vs. 79.6 ± 16.1, P < .0001). However, meta-analysis showed nonsignificantly higher postoperative Rowe and American Shoulder and Elbow Surgeons scores in patients who underwent the OL procedure via an SS technique vs. those in the ST group (96.1 ± 2.6 vs. 86.4 ± 7.6 [P = .57] and 91.6 ± 1.3 vs. 80.6 ± 25.5 [P = .47], respectively). Furthermore, meta-analysis showed that significantly more patients in the ST group had positive lift-off test results (10.0%) when compared with the SS group at final follow-up (2.7%, P = .01). However, meta-analysis indicated that the rate of recurrent instability was trending toward significance in favor of the SS group (0% vs. 11.7%, P = .07). CONCLUSION: Our systematic review established that in cases of OL procedures being carried out via a DP approach, the SS technique results in significantly better functional outcome measures and significantly lower rates of subscapularis insufficiency when compared with an L-shaped ST technique at medium-term follow-up. Furthermore, there were lower rates of recurrent instability that were trending toward significance in favor of the SS technique.
