UNASSIGNED: After arthroscopic Bankart repair (ABR) for anterior glenohumeral instability (GHI), adolescent athletes have higher rates of subsequent recurrent GHI than any other subpopulation. Elucidating which adolescents are at highest risk of postoperative recurrent GHI may optimize surgical decision-making.
UNASSIGNED: To identify prognostic factors associated with subsequent recurrent GHI requiring revision stabilization surgery (RSS) after ABR.
UNASSIGNED: Case-control study; Level of evidence, 3.
UNASSIGNED: The study included patients 12 to 21 years old who had undergone ABR for anterior GHI at a pediatric tertiary care hospital by 1 of 5 sports medicine fellowship-trained surgeons between 2000 and 2020. A multivariate Cox proportional hazards model, with percentage of patients with recurrent GHI undergoing subsequent RSS, was used with a time-to-event outcome analysis. The Cox model effects were expressed as the hazard ratio (HR). All tests were 2-sided, with an alpha of .05.
UNASSIGNED: Records of 488 adolescent patients with ABR (78% male; mean age, 16.9 ± 1.98 years) were analyzed. Of these, 86 patients (17.6%) underwent subsequent RSS for recurrent GHI, yielding a cumulative risk of 8.8% at 2 years, 16.5% at 5 years, and 20% at 15 years. RSS occurred at a mean of 2.6 ± 2.1 years after ABR. Risk factors for RSS included >1 preoperative dislocation (2 dislocations: HR = 7.4, P = .0003; ≥3 dislocations: HR = 10.9, P < .0001), presence of a Hill-Sachs lesion (small: HR = 2.5, P = .0114; medium-large: HR = 4.2, P = .0004), younger age (1-year decrease: HR = 1.2, P = .0015), and participation in contact sports (HR = 1.8, P = .01). Adolescents with only 1 preoperative dislocation had a cumulative incidence of RSS (3.2%), which was significantly lower than those with 2 (24.2%) or ≥3 preoperative dislocations (33.5%).
UNASSIGNED: The number of dislocations before index ABR was the strongest risk factor for recurrent GHI requiring RSS in adolescents with anterior GHI, with 2 dislocations conferring >7-fold increased risk compared with a single preoperative dislocation. Other significant risk factors included the presence of a Hill-Sachs lesion, younger age, and participation in contact sports.

OBJECTIVE: To determine arthroscopic Bankart repair outcomes and recurrence risk factors at a minimum 5-year follow-up.
METHODS: Retrospective assessment of prospectively collected data, single-cohort study of patients who underwent arthroscopic Bankart repair with a minimum 5-year follow-up. Demographical and preoperative instability features were collected. Primary outcome was recurrent instability set as dislocation or subluxation. Secondary outcomes were revision surgery, postoperative instability degree according to Manta criteria, objective and subjective clinical and functional status, assessed by the Rowe, Western Ontario Shoulder Index (WOSI) and Subjective Shoulder Value (SSV) scores. Return to sport and postoperative sports activity at the final follow-up were also recorded.
RESULTS: One-hundred and seventy-two patients, 82% men, average age at surgery 29.5 ± 9.2 years, were included. At a mean follow-up of 8.3 ± 2.6 years, recurrent instability occurred in 53 of 172 patients (30.8%). Revision surgery was required in 23/53 (43.4%) of shoulder with recurrent instability. Recurrence occurred within the first 2 years postoperative in 49% of the shoulders, whereas 51% of recurrences occurred after this period. Recurrence took place after a traumatic event in 25% and 56%, respectively. Recurrence rates were higher in patients who underwent surgery after two or more dislocations (p = 0.029). Patients younger at the time of first dislocation, younger at surgery and those with a higher preoperative degree of instability also showed significantly higher rates of recurrence (p = 0.04, p = 0.02, p = 0.03). Postoperative ROWE, WOSI and SSV scores were significantly worse in patients with recurrent instability (p < 0.001). Return-to-sports rate was also lower in patients with postoperative recurrence (p < 0.001).
CONCLUSIONS: The arthroscopic Bankart repair was associated with a high long-term recurrence rate, and its effectiveness decreased over time. The lowest recurrence rates in arthroscopic Bankart repair were achieved in older patients with only one prior instability episode and a lower instability degree.
METHODS: Level IV.

BACKGROUND: First-time traumatic anterior shoulder dislocation (FASD) is a common trauma associated with shoulder dysfunction. Although several randomized controlled trials have compared conservative and surgical treatments for FASD, the comparative efficacy of these treatments is poorly understood. In this network meta-analysis (NMA), we compared the available evidence on the efficacy of various interventions in patients with FASD.
METHODS: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE databases in March 2023. This NMA included randomized controlled trials comparing conservative and surgical treatments for FASD, including arthroscopic Bankart repair, arthroscopic lavage, external rotation (ER) immobilization, and internal rotation (IR) immobilization. The primary outcomes were redislocation rates, Western Ontario Shoulder Instability Index (WOSI) scores, and adverse events (AEs). We conducted random-effects NMA within the frequentist framework. To rank the treatments, the Surface Under the Cumulative Ranking curve was calculated using a Bayesian framework. We evaluated confidence in each outcome using the CINeMA tool.
RESULTS: Of the 2999 reviewed studies, 15 were included and analyzed. Regarding the primary outcomes, arthroscopic Bankart repair likely results in a large reduction in redislocation rates compared to IR immobilization (risk ratio [RR], 0.15; 95% confidence interval [CI], 0.07-0.33). Both arthroscopic lavage (RR, 0.47; 95% CI, 0.20-1.11) and ER immobilization (RR 0.70; 95% CI, 0.50-1.00) may reduce the redislocation rates slightly compared with IR immobilization. According to these results, arthroscopic Bankart repair ranked first in terms of reducing the redislocation rate, followed by arthroscopic lavage, ER and IR immobilization. Regarding the WOSI score, no substantial differences were observed in the WOSI scores among the four treatments. AEs showed that ER immobilization tended to cause greater shoulder stiffness than IR immobilization, and postoperative erythema, swelling, and adhesive capsulitis were observed after arthroscopic Bankart repair and lavage. However, a meta-analysis was not performed because the definitions of AEs differed between the studies.
CONCLUSIONS: Arthroscopic Bankart repair showed a significant effect in reducing the redislocation rate compared to IR immobilization. Although both arthroscopic lavage and ER immobilization seemed to be effective in reducing the redislocation rates, it was not statistically significant. Moreover, these four treatments may result in little to no difference in disease-specific quality of life and there is no clear evidence of AEs.

BACKGROUND: With stiff competition from alternative albeit more expensive counterparts, it has become important to establish the applicability of metallic anchors for shoulder instability in the modern era. This can be accomplished, in part, by analysing long-term outcomes.
OBJECTIVE: To analyse minimum 10-year outcomes from 30 patients following arthroscopic anterior stabilisation using metallic anchors.
METHODS: Prospectively collected data from arthroscopic Bankart repairs performed using metal anchors during 2007P-2010 were retrospectively analysed in this single-surgeon study. Comprehensive data collection included historical and clinical findings, dislocation details, operative specifics, and follow-up radiological and clinical findings including shoulder scores. The primary outcomes were patient-reported scores (Constant, American Shoulder and Elbow Surgeons [ASES], and Rowe scores) and pain and instability on a visual analogue scale (VAS).
RESULTS: A 3% recurrence rate of dislocation was noted at the final follow-up. Total constant scores at 10 years postoperatively measured between 76 and 100 (mean 89) were significantly better than preoperative scores (mean 62.7). Congruous improvements were also noted in the Rowe and ASES scores and VAS at the 10-year review.
CONCLUSIONS: Reliable long-term outcomes with metallic anchors in surgery for shoulder instability can be expected. Our results provide additional evidence of their continued, cost-effective presence in the modern scenario.

BACKGROUND: Extensive research has been conducted to investigate the short-term and long-term outcomes of arthroscopic Bankart repair, yielding varying results across different populations. However, there remains a dearth of studies specifically focused on evaluating outcomes in recreational athletes.
METHODS: A retrospective case series study was conducted on recreational athletes who underwent isolated arthroscopic Bankart repair between 2013 and 2021. The primary outcome assessed was recurrent instability, defined as dislocation or subluxation. Secondary outcomes included patient satisfaction, rates of returning to the same sports (RTS) and RTS at preinjury level, and patient-reported outcomes. Evaluation of the Rowe score, Constant score, American Shoulder and Elbow Surgeons score, and VAS pain score were performed. Prognostic factors for recurrent instability, including demographic and clinical characteristics, as well as postoperative magnetic resonance imaging (MRI) appearance of the labrum were analyzed.
RESULTS: A total of 191 patients met the selection criteria, with 150 (78.5%) available for the final follow-up. Recurrent instability occurred in 10.7% of patients, with a mean follow-up duration of 4.1 years. Younger age at surgery and more critical glenoid bone loss were significantly associated with recurrent instability (p = .038 and p = .011, respectively). The satisfaction rate regarding surgery was 90.0%. Rates of return to the same sports (RTS) and RTS at preinjury level were 82.0% and 49.3%, respectively. Clinical outcomes measured at the final follow-up were as follows: Rowe score - 92.8; Constant score - 98.0; ASES score - 98.3; VAS pain score - 0.2. Patients with recurrent instability had significantly inferior outcomes in terms of satisfaction rate, RTS at preinjury level rate, Rowe score, and Constant score (p = .000, p = .039, p = .000, and p = .015, respectively). A total of thirty-seven patients underwent MRI examination six months after surgery in our institution. The T2-weighted anterior labrum morphology was found to be poorer in patients with recurrent instability. No significant difference was observed between patients with or without recurrent instability in terms of anterior Slope, anterior labral glenoid height index (LGHI), inferior Slope, inferior LGHI, and T2-weighted inferior labrum morphology.
CONCLUSIONS: Arthroscopic Bankart repair can yield satisfactory medium-term outcomes for recreational athletes. Younger age at surgery, more critical glenoid bone loss, and poorer T2-weighted anterior labrum morphology assessed six months postoperatively were significantly associated with recurrent instability.

OBJECTIVE: This study aimed to evaluate the predictive ability of psychological readiness to return to sports on clinical outcomes and recurrences in athletes who return to sports following shoulder instability surgery.
METHODS: A retrospective analysis was performed of patients who underwent shoulder instability surgery between September 2020 and October 2021 (arthroscopic Bankart repair or Latarjet procedure) with a minimum follow-up of 2 years. Patients were grouped according to the achievement of psychological readiness to return to play using the SIRSI scale (≥ 55 points) measured at 6 months following surgery. Recurrences were measured and functional outcomes were evaluated by the Visual Analogue Scale (VAS), Rowe, and Athletic Shoulder Outcome Scoring System (ASOSS). The minimal clinically important difference (MCID) for the VAS and Rowe scores was calculated using the distribution-based method of ½ standard deviation of the delta (difference between postoperative and preoperative scores). The patient acceptable symptomatic state (PASS) for the VAS scale was set at 2.5 based on previous literature. To evaluate the predictive ability of SIRSI a regression model analysis and a receiver operating characteristic (ROC) curve were used.
RESULTS: A total of 108 who achieved psychological readiness (PSR) and 41 who did not (NPSR) met the study criteria. PSR achieved significantly higher percentages of MCID and PASS thresholds for VAS than NPSR (MCID: 68.5% vs 48.7%, p=0.026; PASS: 92.5% vs 58.5%, p<0.001). However, there were no differences in the percentage of patients achieving MCID for the Rowe score between groups (98.1% vs 100%, p=0.999). The only strongest independent predictor of postoperative outcomes was being psychologically ready to return to sports. The SIRSI scale had an excellent predictive ability for recurrences (area under curve 0.745, 95% CI 0.5-0.8). Of those who sustained a recurrence, 20% were not psychologically ready compared to 4.3% who were (p= 0.002). A power analysis was not conducted for this study.
CONCLUSIONS: The SIRSI scale is associated with postoperative clinical outcomes and recurrences in patients who returned to sports following shoulder instability surgery. Patients who were not psychologically ready following shoulder instability surgery had worse clinical outcomes with fewer patients achieving clinically significant outcomes (PASS and MCID) for pain, and a higher risk of recurrence.
METHODS: Level IV, Retrospective cohort study.

BACKGROUND: Open Bankart repair plus inferior capsular shift and isolated arthroscopic Bankart repair have never been prospectively compared under the concept of glenoid track in collision athletes with recurrent anterior shoulder instability. The aim of this study was to compare the functional outcomes, range of motion, and recurrence rate between these 2 surgical techniques. We hypothesized that open Bankart repair plus inferior capsular shift would provide similar functional outcomes to isolated arthroscopic Bankart repair but with a lower recurrence rate.
METHODS: A prospective cohort study was conducted with 86 collision athletes divided into 2 groups of 43 patients each. All patients had a subcritical glenoid bone loss ≤13.5% and an on-track Hill Sachs lesion. The average follow-up was 66 (60-93) months for the open group and 68 (60-97) months for the arthroscopic group. The primary functional outcomes of each group were evaluated at baseline, 6 months, 1 year and for a minimum of 5 years after surgery. The functional outcomes were also compared between the 2 groups. The assessment tools included the Western Ontario Shoulder Instability Index (WOSI) score and American Shoulder and Elbow Surgeons scale (ASES) score. In addition, recurrent instability and range of motion were also evaluated.
RESULTS: In each group, there were significant differences in Western Ontario Shoulder Instability Index score and American Shoulder and Elbow Surgeons scale score between the pre and postoperative periods. There were no differences between the groups at the end of follow-up (P = .47 and .22). Three dislocations (6.9%) in the open group and 10 dislocations (23.2%) in the arthroscopic group were reported showing significant differences (P = .012). In addition, there were no differences in range of motion between pre and postoperative periods for each group as well as between them.
CONCLUSIONS: We found no differences in functional outcomes and range of motion between the 2 groups. The recurrence rate was significantly higher in the arthroscopic group. We recommend performing open Bankart repair plus inferior capsular shift as a treatment alternative in collision athletes with recurrent anterior shoulder instability.

BACKGROUND: The majority of the current literature on arthroscopic Bankart repair is retrospective, and discrepancies exist regarding clinical outcomes including recurrent instability and return to play among studies of different levels of evidence.
OBJECTIVE: The purpose of this study is to perform a systematic review of the literature to compare the outcomes of prospective and retrospective studies on arthroscopic Bankart repair.
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\" was used, with all results being analyzed via strict inclusion and exclusion criteria. Three independent investigators extracted data and scored each included study based on the 10 criteria of the Modified Coleman Methodology Score out of 100. A χ2 test was performed to assess if recurrent instability, revision, return to play, and complications are independent of prospective and retrospective studies.
RESULTS: A total of 193 studies were included in the analysis, with 53 prospective studies and 140 retrospective in design. These studies encompassed a total of 13,979 patients and 14,019 surgical procedures for Bankart repair for shoulder instability. The rate of redislocation in the prospective studies was 8.0% vs. 5.9% in retrospective studies (P < .001). The rate of recurrent subluxation in the prospective studies was 3.4% vs. 2.4% in retrospective studies (P = .004). The rate of revision was higher in retrospective studies at 4.9% vs. 3.9% in prospective studies (P = .013). There was no significant difference in terms of overall rate to return to play between prospective and retrospective studies (90% and 91%, respectively; P = .548). The overall rate of non-instability complications in the prospective cohort was 0.27% vs. 0.78% in the retrospective studies (P = .002).
CONCLUSIONS: The overall rates of recurrent dislocations-subluxations are higher in prospective studies than retrospective studies. However, rates of revision were reportedly higher in retrospective studies. Complications after arthroscopic Bankart repair are rare in both prospective and retrospective studies, and there was no difference in rates of return to play.

UNASSIGNED: The use of isolated soft tissue repair versus bone block stabilization for the treatment of recurrent anterior shoulder instability in adolescents has no scientific evidence.
UNASSIGNED: To compare the clinical outcomes of adolescent patients who underwent isolated arthroscopic Bankart (iB) repair with those who underwent the arthroscopic Bristow-Latarjet procedure in addition to Bankart (BLB) repair.
UNASSIGNED: Cohort study; Level of evidence, 3.
UNASSIGNED: A total of 60 shoulders in adolescents (aged 13-18 years) were reviewed with a minimum 2 years\' follow-up: iB repair (n = 36) and arthroscopic Bankart repair with an additional Bristow-Latarjet procedure (BLB; n = 24). The characteristics of the patients in each group in terms of age at the first instability episode, age at surgery, hyperlaxity, participation in at-risk sports, and Instability Severity Index Score were comparable. The mean follow-up was longer in the iB group (7.7 vs 4.1 years, respectively), whereas the rates of patients engaged in competition and those with glenoid lesions were higher in the BLB group. The primary outcome measures were failure, defined as the recurrence of instability (clinical dislocation or subluxation), and return to sports. The mean follow-up was 6.2 years (range, 2-16 years).
UNASSIGNED: At the last follow-up, the rate of recurrence was significantly higher in the iB group, with 22% (8/36) failures, than in the BLB group, with 8% (2/24) instability recurrences (P < .05). The rate of return to sports at the same level was significantly higher after the BLB repair than after iB repair (79% vs 47%, respectively; P < .001). No statistical difference was found in patient-reported outcome scores between treatment groups (P > .05). Although failures occurred early after the BLB repair, 88% of failures after iB repair occurred after 2 years. On multivariate analysis, adolescents in the iB group with >3 episodes of preoperative dislocation and shoulder hyperlaxity (external rotation >90°) had a 60% recurrence rate (P < .005).
UNASSIGNED: Adolescent patients undergoing the BLB repair had a lower rate of recurrent instability and higher rates of return to sports and competition than those undergoing iB repair. Patients with shoulder hyperlaxity (external rotation >90°) and >3 dislocations had an unacceptable failure rate of 60% after iB repair.

BACKGROUND: The optimal management of first-time anterior shoulder dislocations (FTASDs) remains controversial. Therefore, the purpose of this study was to assess the efficacy of arthroscopic stabilization surgery for FTASDs through a systematic review and meta-analysis of existing literature.
METHODS: MEDLINE, Embase, and Web of Science were searched from inception to December 18, 2022, for single-arm or comparative studies assessing FTASDs managed with arthroscopic stabilization surgery following first-time dislocation. Eligible comparative studies included studies assessing outcomes following immobilization for an FTASD, or arthroscopic stabilization following recurrent dislocations. Eligible levels of evidence were I to IV. Primary outcomes included rates of shoulder redislocations, cumulative shoulder instability, and subsequent shoulder stabilization surgery.
RESULTS: Thirty-four studies with 2222 shoulder dislocations were included. Of these, 5 studies (n = 408 shoulders) were randomized trials comparing immobilization to arthroscopic Bankart repair (ABR) after a first dislocation. Another 16 studies were nonrandomized comparative studies assessing arthroscopic Bankart repair following first-time dislocation (ABR-F) to either immobilization (studies = 8, n = 399 shoulders) or arthroscopic Bankart repair following recurrent dislocations (ABR-R) (studies = 8, n = 943 shoulder). Mean follow-up was 59.4 ± 39.2 months across all studies. Cumulative loss to follow-up was 4.7% (range, 0%-32.7%). A composite rate of pooled redislocation, cumulative instability, and reoperations across ABR-F studies was 6.8%, 11.2%, and 6.1%, respectively. Meta-analysis found statistically significant reductions in rates of redislocation (odds ratio [OR] 0.09, 95% confidence interval [CI] 0.04-0.3, P < .001), cumulative instability (OR 0.05, 95% CI 0.03-0.08, P < .001), and subsequent surgery (OR 0.08, 95% CI 0.04-0.15, P < .001) when comparing ABR-F to immobilization. Rates of cumulative instability (OR 0.32, 95% CI 0.22-0.47, P < .001) and subsequent surgery rates (OR 0.27, 95% CI 0.09-0.76, P = .01) were significantly reduced with ABR-F relative to ABR-R, with point estimate of effect favoring ABR-F for shoulder redislocation rates (OR 0.59, 95% CI 0.19-1.83, P = .36). Return to sport rates to preoperative levels or higher were 3.87 times higher following ABR-F compared to immobilization (95% CI 1.57-9.52, P < .001), with limited ABR-R studies reporting this outcome. The median fragility index of the 5 included randomized controlled trials (RCTs) was 2, meaning reversing only 2 outcome events rendered the trials\' findings no longer statistically significant.
CONCLUSIONS: Arthroscopic stabilization surgery for FTASDs leads to lower rates of redislocations, cumulative instability, and subsequent stabilization surgery relative to immobilization or arthroscopic stabilization surgery following recurrence. Although a limited number of RCTs have been published on the subject matter to date, the strength of their conclusions is limited by a small sample size and statistically fragile results.
