Objectives: Surgical options for shoulder instability in collision athletes remain controversial. Although arthroscopic soft tissue stabilization is widely accepted treatment for shoulder instability, many surgeons prefer coracoid transfer for collision athletes with or without glenoid defect due to potential high recurrence rate after arthroscopic soft tissue Bankart repair (ABR). In the meantime, Hill-Sacks remplissage (HSR) has been gaining popularity as an effective arthroscopic augmentation procedure. Since 2002, we performed rotator interval closure (RIC) as an augmentation in addition to ABR or arthroscopic bony Bankart repair (ABBR) for collision athletes and obtained satisfactory outcome. However, teen players demonstrated higher recurrence rate compared to twenties and thirties. Therefore, from 2012, we performed HSR as an additional augmentation for teen players besides ABR/ABBR and RIC. The purpose of this study was to assess the outcomes after arthroscopic stabilization in collision athletes who underwent shoulder stabilization under our treatment strategy. Methods: Between 2012 through 2015, 95 consecutive collision athletes underwent shoulder stabilization. Among those, only 2 patients (2%) underwent arthroscopic bony procedure for poor capsular integrity. Among the remaining 93 patients who underwent soft tissue stabilization, 65 were available for minimum 2 year follow-up (70%). Therefore, subjects consisted of 65 players including 54 rugby and 11 American football players (Table 1). There were 13 national top league, 24 collegeate, 21 junior or senior high school, and 7 recreational players. The mean age at surgery was 20 years (range, 16-36). The mean follow-up was 37 months (range, 24-64). We retrospectively reviewed intraoperative findings and surgical procedures using patient records including surgical reports and videos. We also investigated the mean time for sports return, functional outcome and recurrence rate. Pre- and postoperative Rowe scores were compared using paired t test. Results: Preoperative 3DCT of the glenoid demonstrated bony Bankart (fragment type) in 43 players (66%), attritional type in 16 (25%), and normal glenoid in 6 (9%). Mean glenoid bone loss was 15% (range, 0-25) and all of the glenoid with more than 10% bone loss retained bony fragment (Table 2). All 65 players demonstrated Bankart lesion and 15 had concomitant SLAP lesion (23%) which required repair. In addition, 5 players demonstrated capsule tear (8%), which were also repaired. Twenty four players (36%) underwent ABR or ABBR with RIC and forty one players (64%) underwent ABR or ABBR combined with HSR (Table 1).The mean time for sports return was 7 months (range, 4-13) after surgery. The mean Rowe score significantly improved after surgery from 65 (range, 55-75) to 92 (range, 65-100) (P < .001). Recurrence appeared in 2 cases (3%), both of which were junior or senior high school players who underwent ABR with HSR. Conclusion: Soft tissue stabilization combined with selective augmentation procedures for shoulder instability in collision athletes demonstrated satisfactory outcomes with low recurrence rate. Since the incidence of having bony Bankart lesion in collision athletes was very high, arthroscopic bony Bankart repair worked in many patients even with significant glenoid bone loss. Further, HSR seemed to be effective additional augmentation especially in young collision athletes. [Table: see text][Table: see text]

Objectives: Surgical options for shoulder instability in collision athletes remain controversial. Although arthroscopic soft tissue stabilization is widely accepted treatment for traumatic anterior shoulder instability, many surgeons prefer coracoid transfer such as Latarjet procedure for collision athletes with or without glenoid defect due to potential high recurrence rate after arthroscopic soft tissue Bankart repair (ABR). In the meantime, Hill-Sachs remplissage (HSR) has been gaining popularity as an effective arthroscopic augmentation procedure. Since 2002, we performed rotator interval closure (RIC) as an augmentation in addition to ABR or arthroscopic bony Bankart repair (ABBR) for collision athletes and obtained satisfactory outcome.

Conclusion: Soft tissue stabilization combined with selective augmentation procedures for traumatic shoulder instability in collision athletes demonstrated satisfactory outcomes with extremely low recurrence rate. Since the incidence of having bony Bankart lesion in collision athletes was very high, arthroscopic bony Bankart repair worked in many patients even with significant glenoid bone loss. Further, Hill-Sachs remplissage seemed to be effective additional augmentation especially in young collision athletes. [Table: see text]

Background: Many surgeons prefer bony stabilization including Bristow or Latarjet procedures for shoulder instability in collision athletes, even though several potential complications have been reported. There has been a limited number of studies on the midterm outcomes of arthroscopic soft tissue stabilization for anterior shoulder instability in competitive collision athletes. Purpose: To assess the outcomes of arthroscopic soft tissue stabilization in combination with selective augmentation procedures for collision athletes with traumatic anterior shoulder instability Study Design: Case series; Level of evidence, 4. Methods: We retrospectively assessed rugby or American football players (<40 years old) who underwent arthroscopic Bankart or bony Bankart repair with selective augmentations (rotator interval closure and/or Hill-Sachs remplissage) for traumatic anterior shoulder instability between January 2012 and March 2017. Shoulders that required other bony procedures were excluded. Recurrence, complications, return to sport, and functional scores (Rowe score and Subjective Shoulder Value sports score) were investigated. Results: This study included 113 shoulders in 100 patients with a mean age of 20 years (range, 15-36 years) at surgery. Rotator interval closure was performed on 36 shoulders in addition to Bankart repair, and rotator interval closure and Hill-Sachs remplissage were performed on 77 shoulders. The mean follow-up period was 44 months (range, 24-72 months). Of the 113 shoulders, 4 (3.5%) experienced postoperative dislocation, but there were no complications. A total of 93 athletes (93%) attained complete or near complete preinjury sports activity levels. The mean Rowe score significantly improved from 36 (range, 10-75) at presurgery to 96 (range, 35-100; P = .003) at postsurgery. The mean Subjective Shoulder Value sports score significantly improved after surgery, from a mean preoperative score of 22 (range, 0-50) to a postoperative score of 92 (range, 64-100; P = .002). Conclusion: Our treatment strategy, where arthroscopic soft tissue stabilization was combined with selected augmentations, provided good clinical outcomes for competitive collision athletes in terms of low rates of recurrence and complication, a high rate of return to sports, and good shoulder function.

Background: Limited evidence is available regarding the recommended technique of revision surgery for recurrent shoulder instability. Only 1 previous study has compared the results of soft tissue repair and the Latarjet technique in patients with persistent shoulder instability after primary surgical stabilization. Purpose/Hypothesis: To evaluate the results of revision surgery in patients with previous surgical stabilization failure and subcritical glenoid bone defects, comparing repeated Bankart repair versus arthroscopic Latarjet technique. The hypothesis was that Latarjet would be superior to soft tissue procedures in terms of objective and subjective functional scores, recurrence rates, and range of movement. Study Design: Cohort study; Level of evidence, 3. Methods: Included were 45 patients (mean age, 29.1 ± 8.9 years) with subcritical bone loss (<15% of articular surface) who had undergone revision anterior shoulder instability repair after failed Bankart repair. Of these, 17 patients had arthroscopic Bankart repair and 28 had arthroscopic Latarjet surgery. Patients were evaluated at a minimum of 2 years postoperatively with the Rowe score, Western Ontario Shoulder Instability Index, and Subjective Shoulder Value. Subluxation or dislocation episodes were considered failures. Results: No statistically significant differences were found between groups in age, sex, sporting activity, preoperative Rowe score, or the presence of hyperlaxity or bony lesions. At revision arthroscopy, 20 shoulders showed a persistent Bankart lesion, 13 a medially healed labrum, and 6 a bony Bankart. In 6 patients, no abnormalities were present that could explain postoperative recurrence. In the Bankart repair group, 7 patients underwent isolated Bankart procedures; in the remaining 10 cases, a capsular shift was added. No significant differences were found between the Bankart and Latarjet groups in outcome scores, recurrence rate (11.8% vs 17.9%, respectively), or postoperative athletic activity level. The mean loss of passive external rotation at 0° and 90° of abduction was similar between groups. Conclusion: Arthroscopic Latarjet did not lead to superior results compared with repeated Bankart repair in patients with subcritical glenoid bone loss and recurrent anterior shoulder instability after Bankart repair.

Background: Traumatic glenohumeral dislocation of the shoulder is one of the most common shoulder injuries, especially among adolescent athletes. The treatment of instability for young athletes continues to be controversial owing to high recurrence rates. Purpose: To investigate the recurrence rate of shoulder instability after arthroscopic capsulolabral repair for adolescent contact and collision athletes. Study Design: Case series; Level of evidence, 4. Methods: Sixty-seven patients aged <18 years underwent an arthroscopic labral repair over a 5-year period. The mean ± SD age of the cohort was 16.3 ± 0.9 years (range, 14-17 years) and consisted of 1 female and 66 males. All patients were contact athletes, with 62 of 67 playing rugby. Demographic, clinical, and intraoperative data for all patients with shoulder instability were recorded in our database. Recurrence rates were recorded and relative risks calculated. Results: At a follow-up of 33 ± 20 months, 34 of 67 patients had recurrent instability for an overall recurrence rate of 51% among adolescent contact athletes after arthroscopic labral repair surgery. The mean time to recurrence was 68.1 ± 45.3 weeks. All recurrences occurred as a result of a further sporting injury. Relative risk analysis demonstrated that athletes aged <16 years had 2.2 (95% CI, 1.2-2.1) times the risk of developing a further instability episode as compared with athletes aged ≥16 years at the time of index surgery ( P = .0002). The recurrence rate among adolescent athletes after bony Bankart repairs was 57.9% versus 47.9% for soft tissue labral repairs ( P = .4698). The incidence of Hill-Sachs lesions ( P = .0002) and bony Bankart lesions ( P = .009) among adolescent athletes was significantly higher than among adult controls ( P = .002). The presence of bone loss did not lead to a significant increase in recurrence rate over and above the effect of age. Conclusion: Adolescent contact athletes undergoing arthroscopic labral repair have an overall recurrence rate of 51%. Rugby players who undergo primary arthroscopic shoulder stabilization aged <16 years have 2.2 times the risk of developing a further instability episode when compared with athletes aged ≥16 years at the time of index surgery, with a recurrence rate of 93%.

Objectives The two most common surgical interventions for recurrent anterior shoulder instability include arthroscopic Bankart repair and the Latarjet procedure. However, indications for each procedure remain debated between surgeons with 90% of surgeons (except French surgeons) preferring soft tissue Bankart repair initially. It remains unclear whether the results of a Latarjet procedure performed after a failed arthroscopic Bankart repair differ from those performed for primary cases. The purpose of our study was to compare the postoperative outcomes of patients who had undergone a Latarjet as a primary surgery versus those who had had a Latarjet as revision surgery for a failed arthroscopic Bankart repair Methods Patients who had undergone open or arthroscopic Latarjet procedure between 2003 and 2015 in 5 fellowship-trained surgical practices were included. Charts were retrospectively reviewed to identify patients who had undergone a primary Latarjet or those who had had a Bankart repair prior to the Latarjet. Age, ISIS score, BMI, sports activity, hyperlaxity and delay before surgery were retrospectively collected. Outcome measures were prospectively collected, including range of motion, SSV, Walch-Duplay, scores, recurrence of instability, apprehension or new surgery. Results A total of 311 patients were included. 28% of the patients were lost to follow-up and the mean follow-up was 3.4 years +/-0.8. There were 21 patients who had had a Bankart repair prior to the Latarjet procedure. Both populations were comparable regarding preoperative data. The postoperative instability rate was 3% in the overall population; 4.8% in the “primary Latarjet” group and 2.3% in the ”Latarjet for failed Bankart” group. This difference was not significant (p=0.50). However, the mean Walch-Duplay score was significantly lower and the pain scores significantly higher in patients who had had a prior Bankart repair: 51.9 +/- 25 versus 72.1 +/- 25.2 and 2.5/10 versus 1.2/10 respectively. The Simple Shoulder Test was comparable in both groups. Conclusion The study confirms that the Latarjet is an effective procedure to treat primary chronic anterior instability and also to stabilize a shoulder after a failed Bankart repair. However, the thought that a Bankart repair does not “burn any bridges” appears to be incorrect relative to postoperative pain and functional scores in the setting of future Latarjet procedure.

Background: The management of recurrent instability after arthroscopic Bankart repair remains challenging. Of the various treatment options, arthroscopic revision repairs are of increasing interest due to improved visualization of pathology and advancements in arthroscopic techniques and instrumentation. Purpose: We sought to assess the indications, techniques, outcomes, and complications for patients undergoing revision arthroscopic Bankart repair after a failed index arthroscopic soft-tissue stabilization for anterior shoulder instability. Methods: We performed a systematic review of studies identified by a search of Medline, Embase, and PubMed. Our search range was from data inception to April 29, 2020. Outcomes include clinical outcomes and rates of complication and revision. The Methodological Index for Non-randomized Studies (MINORS) was used to assess study quality. Data are presented descriptively. Results: Twelve studies were identified, comprising 279 patients (281 shoulders) with a mean age of 26.1 ± 3.8 years and a mean follow-up of 55.7 ± 24.3 months. Patients had improvements in postoperative outcomes (eg, pain and function). The overall complication rate was 29.5%, the most common being recurrent instability (19.9%). Conclusion: With significant improvements postoperatively and comparable recurrent instability rates, there exists a potential role in the use of revision arthroscopic Bankart repair where the glenoid bone loss is less than 20%. Clinicians should consider patient history and imaging findings to determine whether a more rigorous stabilization procedure is warranted. Large prospective cohorts with long-term follow-up and improved documentation are required to determine more accurate failure rates.

Background: Literature on arthroscopic stabilization in adolescent patients participating in collision and contact sports is limited, as most studies include adolescents within a larger sample group comprised primarily of adults. Purpose: To review the outcomes of arthroscopic Bankart repair for anterior shoulder instability in an adolescent population participating in collision and contact sports. Study Design: Case series; Level of evidence, 4. Methods: This retrospective review included 39 shoulders in 37 adolescent (≤19 years) athletes who underwent primary arthroscopic Bankart repair using suture anchors with at least 2-year follow-up. All patients had a history of trauma to their shoulder resulting in an anterior dislocation. Outcome measures included patient satisfaction, the visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score. Recurrence of dislocation and return to sporting activity were also assessed. Results: The mean age at the time of surgery was 16.9 years (range, 15-19 years), and the mean follow-up was 6.3 years (range, 4.3-10.0 years); 58.6% of patients participated in collision sports. Time to surgery after the initial dislocation episode was 9.2 months (range, 0.5-36.2 months). Four shoulders (10.3%) had dislocation events postoperatively. The majority (78.1%) of patients returned to sports at the same level of competition. Mean VAS was 0.49 ± 1.0, and the mean ASES and Rowe scores were 92.8 ± 12.6 and 85.0 ± 24.2, respectively. Univariate analyses demonstrated that subjective functional outcomes were negatively correlated with recurrence (ASES, P = .005; Rowe, P = .001) and failure to return to sport (ASES, P = .016; Rowe, P = .004). Independent variables shown to have no significant relationship to functional outcomes included age, follow-up, number of preoperative dislocations, time to surgery, sport classification, competition level, tear extent, number of anchors, concurrent Hill-Sachs lesion, and repair of a superior labral anterior-posterior (SLAP) lesion. Conclusion: Arthroscopic Bankart repair is an effective surgical option for traumatic shoulder instability in adolescents participating in collision and contact sports. At a minimum 4-year follow-up, arthroscopic Bankart repair effectively restored stability in 90% of cases; 80% returned to their preinjury level of sport.

Background: Age at surgery plays a crucial role in the frequency of recurrent shoulder instability. However, there are few studies that evaluate the relationship between age at initial shoulder instability and overall outcomes after stabilization surgery. Purpose: To compare clinical outcomes and structural changes after arthroscopic Bankart repair in patients who experienced initial shoulder instability during adolescence versus those with later onset instability. Study Design: Cohort study; Level of evidence, 3. Methods: This study included patients who underwent arthroscopic Bankart repair at a single institution between 2007 and 2017. Comparisons were made between patients who experienced initial shoulder instability during adolescence (age 13-19 years; group A) and those with later onset instability (age 20-35 years; group B). Clinical outcomes (recurrence rate, postoperative pain, functional scores, active range of motion, and return to sports) and structural changes demonstrated by magnetic resonance imaging (MRI) were evaluated at minimum 2-year follow-up. In addition, functional outcomes within each group were compared between the patients with and without postoperative recurrence. Results: A total of 58 patients were included (24 patients in group A and 34 patients in group B). The mean follow-up was 72.1 months. Group A demonstrated a significantly higher recurrence rate than group B (41.7% vs 11.8%, respectively; P = .009; risk ratio, 5.36 [95% CI, 1.43-20.09]) as well as significantly lower Rowe (76.9 ± 20.1 vs 88.7 ± 13.2, respectively; P = .01) and Constant-Murley scores (92.2 ± 7.6 vs 96.3 ± 4.2, respectively; P = .01). Postoperative MRI revealed no significant structural differences between the groups regarding the glenoid labrum, glenohumeral cartilage, or osseous reaction around the implanted anchors. In group A, patients with recurrence had less satisfaction regarding postoperative sports level than those without recurrence, whereas in group B, patients with recurrence had more postoperative pain and functional impairment compared with those without recurrence. Conclusion: Initial shoulder instability during adolescence was associated with a higher recurrence rate and lower functional scores after arthroscopic Bankart repair compared with later onset instability, although no significant structural differences were found between the groups on MRI at a mean 6-year follow-up.

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.

Objectives: For shoulders of artistic gymnasts, stability against various forces such as weight bearing, torsion, and traction is required as well as wide range of motion. The prevalence of shoulder instability in gymnasts has been reported to be high, particularly in female gymnasts; however, there has been no report on its pathology and the surgical outcomes. The purpose of this study was to retrospectively investigate the pathology and surgical outcomes of anterior traumatic shoulder instability in gymnasts. Methods: The subjects of this study were 18 shoulders of 16 gymnasts that underwent arthroscopic surgery for anterior traumatic shoulder instability. They consisted of 4 male and 14 female shoulders with a mean age of 18 years (range, 16-20). The mean follow-up was 30 months (range, 10-66 months). All surgeries were performed arthroscopically, and procedures were determined according to the intraoperative findings. Patients were immobilized with a brace for 3 weeks and started range of motion exercise after the immobilization period. Hand-stand or hanging were normally allowed at 3 month after surgery according to patients’ functional recovery. We investigated injury mechanism, intraoperative findings, surgical procedures, times to start hand-stand or hanging and to start giant swing, time to complete return to gymnastics, and recurrence of instability. Results: Three shoulders experienced dislocations that self-reduction was impossible. The remaining 15 shoulders had self-reducible dislocations or subluxations, and 10 of 15 shoulders were injured with the shoulder hyper-flexed: e.g., pulling up hands during somersaults; pushing off the vault (Figure). Bankart lesion was identified during surgery in 14 shoulders including one bony Bankart lesion. Capsular tear was found in 5 shoulders, and only one lesion was concomitant with Bankart lesion. All lesions were arthroscopically repaired. We additionally performed rotator interval closure in 10 shoulders, superior labrum repair in 13, and rotator cuff repair in 2. One patient retired from gymnastics immediately after surgery, and 2 patients were lost to follow-up. The remaining 13 patients returned to gymnastics. The mean time to start hand-stand or hanging was 4 months (range, 3-10 months), and that to start giant swing was 6 months (range, 3-15 months). The mean time to complete return was 9 months (range, 5-17 months). Two shoulders experienced recurrence (1 dislocation and 1 subluxation) after return to gymnastics. Both shoulders underwent revision surgery and returned to gymnastics. Conclusions: Capsular tear without Bankart lesion was more common (4 shoulder, 22%) in gymnasts than general population. The sport-related characteristics might be associated with the high incidence of capsular tear. The outcomes of arthroscopic stabilization for gymnasts was good with the high complete return rate.
