Background: The debate continues regarding the optimal treatment of intercollegiate contact athletes with in-season anterior shoulder instability. Purpose: To examine return to sport and recurrent instability in the season after the index in-season anterior instability event. Study Design: Cohort study; Level of evidence, 2. Methods: Forty-five contact intercollegiate athletes treated nonoperatively or with arthroscopic stabilization were prospectively followed in a multicenter observational study to evaluate return to play (RTP) and recurrent instability in the season after an initial in-season anterior glenohumeral instability event. Baseline data collection included sport played, previous instability events, direction of instability, type of instability (subluxation or dislocation), and treatment method (nonoperative management or arthroscopic stabilization). All nonoperatively treated athletes underwent a standardized accelerated rehabilitation program without shoulder immobilization. Surgical stabilization was performed arthroscopically in all cases, and successful RTP was evaluated during the next competitive season after complete rehabilitation. Results: Thirty-nine of 45 intercollegiate contact athletes had remaining National Collegiate Athletic Association eligibility and were followed through the subsequent competitive season after the index instability event. Of the 10 athletes electing nonoperative treatment, 4 (40%) successfully returned to play without recurrence during the subsequent season. Of the 29 athletes treated surgically, 26 (90%) were able to successfully return to play without recurrence the following season (recurrence: n = 1; inadequate function: n = 2). Athletes who underwent surgical reconstruction before the next season were 5.8 times (95% CI, 1.77-18.97; P = .004) more likely to complete the subsequent season without recurrent instability. Of the 29 athletes electing surgical stabilization, there was no difference (risk ratio, 0.95; 95% CI, 0.10-9.24; P > .99) in RTP between the 9 stabilized after a single instability event (90% RTP rate) and the 20 stabilized after multiple in-season recurrent instability events (89% RTP rate). Conclusion: Collegiate contact and collision athletes with in-season anterior shoulder instability are significantly more likely to successfully return to sport without subsequent instability events the next season if they undergo surgical repair in the off-season.

Background: Young age and contact sports have been postulated as risk factors for anterior shoulder instability. Management after shoulder instability is controversial, with studies suggesting that nonoperative management increases the risk of recurrence. Several studies examined return to play after an in-season instability episode, and few followed these patients to determine if they were able to successfully compete in a subsequent season. No study has evaluated this question in a high school athlete population. Purpose: To compare the likelihood of return to scholastic sport and complete the next full season without an additional time-loss injury among athletes with anterior shoulder instability in terms of treatment, instability type, and sport classification. Study Design: Cohort study; Level of evidence, 2 Methods: Athletes were included in this study as identified by a scholastic athletic trainer as experiencing a traumatic time-loss anterior shoulder instability injury related to school-sponsored participation. The cohort was predominantly male (n = 108, 84%) and consisted mostly of contact athletes (n = 101, 78%). All athletes had dislocation or subluxation diagnosed by a board-certified physician who determined the athlete’s course of care (nonoperative vs operative). Successful treatment was defined as completion of care and return to the athlete’s index sport, with full participation for the following season. Chi-square and relative risk analyses were completed to compare success of treatment (nonoperative vs operative care) and instability type. Separate logistic regressions were used to compare the effect of sex and sport classification on the athletes’ ability to return to sport. Statistical significance was set a priori as α = .05. Results: Scholastic athletes (N = 129) received nonoperative (n = 97) or operative (n = 32) care. Nonoperatively treated (85%) and operatively treated (72%) athletes successfully returned to the same sport without injury for at least 1 full season ( P = .11). Players sustaining a dislocation were significantly more likely to fail to return when compared with those sustaining a subluxation (26% vs 89%, P = .013). Sex ( P = .85) and sport classification ( P = .74) did not influence the athlete’s ability to return to sport, regardless of treatment type. Conclusion: A high percentage of athletes with shoulder instability achieved successful return to sport without missing any additional time for shoulder injury. Those with subluxations were at almost 3 times the odds of a successful return compared with those sustaining a dislocation.

Background: Open Bankart repair provides surgeons and patients with an alternative solution for managing recurrent instability in young athletes with or without minimal bone loss. Despite many studies that have reported low recurrence rates and good functional outcomes after open Bankart repair, we have limited knowledge about the return to sport and work for high-demand populations. Purpose: To assess the return to sport and work for high-demand populations after open Bankart repair for recurrent anterior shoulder instability, outcomes of open Bankart repair with regard to recurrence, and development of osteoarthritic (OA) changes. Study Design: Systematic review; Level of evidence, 4. Methods: We searched PubMed, EMBASE, Cochrane Library, Scopus, and Google Scholar databases using keywords as well as Medical Subject Headings terms and Emtree using “(Open Bankart OR Bankart surgery) (NOT arthroscopy NOT revision)” for English-language studies. We conducted a systematic review in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results: In total, 11 articles (10 with level 4 and 1 with level 3 evidence) including 563 patients (566 shoulders) were identified. The majority of patients were male (82%), the average age at the time of surgery was 27.4 years, and the mean follow-up was 11.5 years (range, 2.5-29 years). The most common functional score used was the Rowe score (95%) for the reported outcome measures, which showed good to excellent results (mean, 88.5 points). The overall recurrent instability rate, including dislocation and subluxation as a postoperative complication, was 8.5%. A total of 87% of patients were able to return to sport and work postoperatively. Overall, OA changes were reported in 33% of the patients, and the overall revision rate was 1%. Conclusion: Open Bankart repair exhibited favorable results, with a low postoperative instability rate. It is a reliable surgical procedure that allows high-demand patients to return to sport and work.

Arthroscopic Shoulder Stabilization

Objectives: Recurrent shoulder instability after arthroscopic shoulder stabilization is a challenging complication that often manifests after return to sports. Many physicians use an arbitrary minimum of 5 months from surgery for clearance, although there is little data to support the use of temporal based criteria. Prior literature on ACL reconstruction has demonstrated overwhelming evidence for improved failure rates following return to sport after criteria based testing compared to time based clearance, but no such studies to date have evaluated the use of objective return to play testing protocols on recurrence rates following arthroscopic shoulder stabilization. We have prior presented on a return to sport criteria-based protocol that has demonstrated that a majority of athletes have residual strength and functional limitations which would preclude them from full clearance and return to play at 6 months postoperatively. The purpose of this study is to analyze the impact of a return to play criteria-based testing protocol on recurrent instability following arthroscopic shoulder stabilization. We hypothesized that patients who meet return to play criteria would have less recurrent instability compared to those who did not undergo the testing and were cleared to return based on time from surgery. Methods: Forty eight patients (group I) who underwent arthroscopic shoulder stabilization surgery from 2016 to 2018 with minimum 1 year follow up and were referred during postoperative rehabilitation for functional testing to evaluate readiness for return to sport were included in this retrospective case controlled study. These patients were compared to a control group of forty-eight historical consecutive cases (group II) who did not undergo return to sports testing and were cleared for sports after a minimum of 5 months following surgery. Patients with critical glenoid bone loss or off-track Hill-Sach’s lesions necessitating a remplissage or bone augmentation procedure were excluded from the study. ANOVA and independent t test were performed to analyze recurrence shoulder instability rates defined as dislocations or subluxation symptoms. Results: There was no difference between groups with regard to age ( p=0.64), sex (p=0.24), hand dominance (p=0.84), or participation in contact sports (p=0.66). Patients who underwent return to play criteria based testing protocol had a statistically significant difference in the rate of recurrent shoulder instability (10% vs. 31%, odds ratio=3.9, p<0.001). Conclusion: Athletes who undergo an objective return to play criteria based testing protocol have lower rates of recurrent instability following arthroscopic shoulder stabilization surgery than those cleared by time from surgery. Based on our findings, we strongly recommend the utilization of a criteria based testing protocol for return to play following arthroscopic shoulder stabilization, particularly for sports that have known higher risks of recurrence.

Background: Anterior shoulder instability is a common clinical condition that often requires surgical stabilization. Glenoid labral tears are often associated with instability, with glenolabral articular disruption (GLAD) lesions occasionally being identified arthroscopically during repair, particularly in collision athletes. Purpose: To evaluate the clinical outcomes and recurrence rates in patients who had GLAD lesions and underwent arthroscopic Bankart repair (ABR) and compare them with a control group without GLAD lesions. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective review of patients who underwent ABR with GLAD lesions, by a single surgeon between July 2012 and March 2017, was performed. Additionally, these were pair matched in a 2:1 ratio for age, sex, sport, and level of play with a control group who underwent ABR without GLAD lesions. Return to sport, the level of return, and the timing of return were assessed. The visual analog scale (VAS) for pain score, Rowe score, Shoulder Instability–Return to Sport after Injury (SIRSI) score, and Subjective Shoulder Value (SSV) were evaluated. Results: The study included a total of 66 patients (22 and 44 patients for the GLAD and control groups, respectively), with a mean age of 25.8 years and a mean follow-up of 66 months. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SIRSI, and SSV) utilized for the GLAD and control groups ( P > .05 for all). Similarly, there was no significant difference in the total rate of return to play (90.9% vs 88.6%; P > .99) or return at the same/higher level (68.2% vs 72.7%; P = .78). There was no significant difference in timing of return to play (6.3 ± 6.6 months vs 6.4 ± 2.5 months; P = .98). There were 3 cases (13.6%) requiring further surgery (1 revision stabilization, 1 arthroscopic release, and 1 rotator cuff repair) in the GLAD group and 2 cases (4.5%) requiring further surgery (both revision stabilization) in the control group; the difference was not statistically significant ( P = .32). Conclusion: After arthroscopic repair, patients with GLAD lesions had similar midterm outcomes when compared with a control group without GLAD lesions.

Background: The treatment of traumatic anterior shoulder instability in professional Australian Football League (AFL) players is challenging, with an emphasis on early return to play and avoidance of instability recurrence. Purpose: To investigate return-to-sport (RTS) outcomes and complications after 2 different procedures for traumatic anterior shoulder instability in professional AFL players. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively reviewed our surgical database for professional AFL players who underwent capsulolabral stabilization or open Latarjet procedure by a single surgeon between 2006 and 2017. Outcomes included RTS, on-field performance, and complications. Between-group analyses for RTS and complications were estimated using Kaplan-Meier survival analyses. Within-group analyses for on-field performance data were performed using paired t tests with significance set at .05. Results: A total of 58 capsulolabral stabilization procedures in 54 players and 32 Latarjet procedures in 29 players were included in the analysis; 93.1% of capsulolabral patients and 96.9% of Latarjet patients returned to professional AFL. The median RTS time was 6.8 months for the capsulolabral group and 7.3 months for the Latarjet group. There was no significant difference in RTS rates between the 2 groups ( P = .270). Of those undergoing surgery early in the season, 75% of the capsulolabral and 71% of Latarjet group were able to RTS within the same season, at a mean time of 16.9 weeks and 18.8 weeks, respectively. There was a significant difference in instability recurrence, with 19% for the capsulolabral group and no recurrence in the Latarjet group ( P = .017). There was no significant reduction in player on-field performance in either group ( P < .05). Conclusion: In this study, the median RTS in AFL players was approximately 7 months after capsulolabral and Latarjet surgery with no compromise to on-field performance. Instability-related complications occurred only in the capsulolabral group, and the incidence increased with time.

Redislocation Rate

Background: There exists limited objective functional return-to-play criteria after surgical stabilization for anterior shoulder instability in the competitive athlete. Hypothesis: The proposed functional rehabilitation program and psychological evaluation after arthroscopic Bankart repair will help athletes return to sport with a decreased redislocation rate on return. Study Design: Case series. Level of Evidence: Level 4. Methods: Participants were contact or overhead athletes at the high school or collegiate level. Each underwent arthroscopic Bankart repair after a single dislocation event, with less than 10% glenoid bone loss. Western Ontario Shoulder Instability Index (WOSI) scores, Single Assessment Numeric Evaluation (SANE) scores, and American Shoulder and Elbow Surgeons (ASES) scores were evaluated pre- and postoperatively. Athletes were only allowed to return to competition after completing the proposed functional and psychological rehabilitation protocol. Results: A total of 62 participants were enrolled (52 male, 10 female; average age, 18.7 years (range 16-24 years); mean Instability Severity Index Score, 5.63 ± 0.55). All returned to sport for 1 full season and completed a minimum of 2 years of follow-up. The average time to pass functional testing was 6.2 ± 0.7 months, psychological testing was 5.2 ± 0.5 months, and return to sport was 6.5 ± 0.7 months. SANE scores improved from 44.3 to 90.0, ASES from 45.5 to 89.3, and WOSI from 1578.0 to 178.9 (all P < 0.001). Redislocation rate was 6.5% (4 of 62). Conclusion: The proposed functional rehabilitation and psychological assessment protocol is safe and effective in returning athletes to sport after arthroscopic surgical intervention for anterior shoulder instability. This demonstrated a low redislocation rate after 2-year follow-up. Clinical Relevance: Most return-to-play protocols after arthroscopic Bankart repair are centered on recovery time alone, with limited focus on functional rehabilitation, psychological assessment, and return-to-play testing parameters. To our knowledge, this is the first study to propose a dedicated rehabilitation program incorporating functional testing, psychological readiness, and return-to-play criteria for competitive athletes recovering from arthroscopic shoulder stabilization.

Background: Few studies have compared clinical outcomes between the traditional Latarjet procedure for anterior shoulder instability and the congruent arc modification to the Latarjet procedure. Purpose: To systematically evaluate the literature for the incidence of recurrent instability, clinical outcomes, radiographic findings, and complications for the traditional Latarjet procedure and the congruent arc modification and to compare results of each search. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review and meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We included studies published between January 1990 and October 2020 that described clinical outcomes of the traditional Latarjet and the congruent arc modification with a follow-up range of 2 to 10 years. The difference in surgical technique was analyzed using a chi-square test for categorical variables, while continuous variables were evaluated using a Student t test. Results: In total, 26 studies met the inclusion criteria: 20 studies describing the traditional Latarjet procedure in 1412 shoulders, and 6 studies describing the congruent arc modification in 289 shoulders. No difference between procedures was found regarding patient age at surgery, follow-up time, Rowe or postoperative visual analog scores, early or late complications, return-to-sport timing, or incidence of improper graft placement or graft fracture. A significantly greater proportion of male patients underwent glenoid augmentation using the congruent arc modification versus traditional Latarjet ( P < .001). When comparing outcomes, the traditional Latarjet procedure demonstrated a lower incidence of fibrous union or nonunion ( P = .047) and broken, loose, or improperly placed screws ( P < .001), and the congruent arc modification demonstrated improved outcomes with regard to overall return to sport ( P < .001), return to sport at the same level ( P < .001), incidence of subluxation ( P = .003) or positive apprehension ( P = .002), and revision surgery for recurrent instability ( P = .027). Conclusion: Outcomes after the congruent arc modification proved at least equivalent to the traditional Latarjet procedure in terms of recurrent instability and return to sport, although early and late complications were equivalent. The congruent arc procedure may be an acceptable alternative to traditional Latarjet for the treatment of anterior shoulder instability with glenoid bone loss; however, long-term outcomes of this procedure are needed.

Risk Of Failure

Objectives: The management of the adolescent athlete who presents for initial treatment after shoulder instability remains controversial. Risk factors such as age, gender, athletic status, and patient goals have all been demonstrated to result in a higher risk of recurrence with nonoperative management, but little work has been done to determine a treatment algorithm that would combine these factors into a decision making algorithm. The purpose of this study, therefore, was to evaluate patients managed nonoperatively for shoulder instability, and to identify factors that led to failure, defined as an inability to return to sport with no subsequent missed time due to shoulder issues. We sought to integrate these factors into a scoring system that would predict the success or failure of nonoperative management in the treatment of shoulder instability in the adolescent athlete. Methods: A retrospective study was conducted of 57 patients who were first time presenters for anterior shoulder instability to a single orthopaedic practice. Inclusion criteria were that patients were managed nonoperatively, that they were involved in high school sports with at least one season of eligibility remaining, and that complete information was available on their ultimate return to their previous sport. Success was defined as those patients who returned to their sport at the same level, and who played at least one subsequent season without any time being missed due to the shoulder that had been unstable. Patient specific risk factors were individually evaluated, and those that were predictive of a higher risk of failure were incorporated into a 10-point Nonoperative Injury Severity Index (NISIS). This score was then retrospectively applied with regression analysis as well as a chi-square analysis to determine the overall score that predicted failure of nonoperative management. Results: Six factors were identified as risk factors and included in the NISIS. Age greater than 15, the presence of bone loss, type of instability (subluxation or dislocation), type of sport (collision vs. non-collision), female gender, and arm dominance, were assigned points based on individual risk. Overall, 79% of patients treated nonoperatively were able to achieve full return to sport without subsequent surgical intervention or missing any time as a result of their shoulder. Patients who had a preoperative NISIS score of >7 returned at over 90% to sport, compared to a success rate of 50% for those who scored <8, revealing an odds ratio of 9.3 times higher risk of failure for those in the high risk group (p=0.001). Conclusion: The non-operative instability severity index is simple and effective preoperative method to determine who is likely to be successful at returning to scholastic sports after presenting for anterior shoulder instability. Further study with a larger prospective cohort should be accomplished to independently validate this score, but this information may be useful for the treating physician to help guide decision making when presented with the unstable shoulder.

Background Recent literature has demonstrated that the success rates of arthroscopic stabilization of glenohumeral instability deteriorate in patients with an anteroinferior glenoid bone deficiency, also known as the “inverted pear” glenoid. Purpose This study was conducted to assess the outcomes of arthroscopic stabilization for recurrent anterior shoulder instability in patients with a mean anteroinferior glenoid bone deficiency of 25% (range, 20%-30%). Study Design Cohort study; Level of evidence, 3. Methods Twenty-one of 23 patients (91% follow-up) undergoing arthroscopic stabilization surgery and noted to have a bony deficiency of the anteroinferior glenoid of 20% to 30% were reviewed at a mean follow-up of 34 months (range, 26-47). The mean age was 25 years (range, 20-34); 2 patients were female and 19 were male. All patients were treated with a primary anterior arthroscopic stabilization using a mean of 3.2 suture anchors (range, 3-4). Eleven patients had a bony Bankart that was incorporated into the repair; 10 had no bone fragment and were considered attritional bone loss. Outcomes were assessed using the Rowe score, the American Shoulder and Elbow Surgeons (ASES) Score, the Single Assessment Numeric Evaluation (SANE), and the Western Ontario Shoulder Instability (WOSI) Index. Findings of recurrent instability and dislocation events were documented. Results Two patients (9.5%) experienced symptoms of recurrent subluxation, and 1 (4.8%) sustained a recurrent dislocation that required revision open surgery. The mean postoperative outcomes scores were as follows SANE = 88.1 (range, 65-100; standard deviation [SD] 9.0); Rowe = 85.2 (range, 55-100; SD 14.1); ASES Score = 93.1 (range, 78-100; SD 5.3); and WOSI Index = 398 (82% of normal; range, 30-1175; SD 264). No patient with a bony fragment experienced a recurrent subluxation or dislocation, and mean outcomes scores for patients with a bony fragment were better than those with no bony fragment (P = .08). No patient required medical discharge from the military for his or her shoulder condition. Conclusions Arthroscopic stabilization for recurrent instability, even in the presence of a significant bony defect of the glenoid, can yield a stable shoulder; however, outcomes are not as predictable especially in attritional bone loss cases. Longer-term follow-up is needed to see if these results hold up over time.
