Background: Current literature reports highly satisfactory short- and midterm clinical outcomes in patients with arthroscopic 270° labral tear repairs. However, data remain limited on long-term clinical outcomes and complication and redislocation rates in patients with traumatic shoulder instability involving anterior, inferior, and posterior labral injury. Purpose: To investigate, at a minimum follow-up of 10 years, the clinical outcomes, complications, and recurrent instability in patients with 270° labral tears involving the anterior, inferior, and posterior labrum treated with arthroscopic stabilization using suture anchors. Study Design: Case series; Level of evidence, 4. Methods: A retrospective outcomes study was completed for all patients with a minimum 10-year follow-up who underwent arthroscopic 270° labral tear repairs with suture anchors by a single surgeon. Outcome measures included pre- and postoperative Rowe score, American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test, visual analog scale for pain, and Single Assessment Numeric Evaluation (SANE). Western Ontario Shoulder Instability Index (WOSI) scores were collected postoperatively. Complication data were collected, including continued instability, subluxation or dislocation events, and revision surgery. Failure was defined as any cause of revision surgery. Results: In total, 21 patients (mean ± SD age, 27.1 ± 9.6 years) with 270° labral repairs were contacted at a minimum 10-year follow-up. All outcome measures showed statistically significant improvements as compared with those preoperatively: Rowe (53.9 ± 11.4 to 88.7 ± 8.9; P = .005), ASES (72.9 ± 18.4 to 91.8 ± 10.8; P = .004), Simple Shoulder Test (8.7 ± 2.4 to 11.2 ± 1.0; P = .013), visual analog scale (2.5 ± 2.6 to 0.5 ± 1.1; P = .037), and SANE (24.0 ± 15.2 to 91.5 ± 8.3; P = .043). The mean postoperative WOSI score at minimum follow-up was 256.3 ± 220.6. Three patients had postoperative complications, including a traumatic subluxation, continued instability, and a traumatic dislocation, 2 of which required revision surgery (14.2% failure rate). Conclusion: Arthroscopic repairs of 270° labral tears involving the anterior, inferior, and posterior labrum have highly satisfactory clinical outcomes at 10 years, with complication and redislocation rates similar to those reported at 2 years. This suggests that repairs of extensile labral tears are effective in restoring and maintaining mechanical stability of the glenohumeral joint in the long term.

Background: Nearly all studies describing shoulder stabilization focus on male patients. Little is known regarding the clinical outcomes of female patients undergoing shoulder stabilization, and even less is understood about females with glenoid bone loss. Purpose: To assess the clinical outcomes of female patients with recurrent anterior shoulder instability treated with the Latarjet procedure. Study Design: Case series; Level of evidence, 4. Methods: All cases of female patients who had recurrent anterior shoulder instability with ≥15% anterior glenoid bone loss and underwent the Latarjet procedure were analyzed. Patients were evaluated after a minimum 2-year postoperative period with scores of the American Shoulder and Elbow Surgeons form, Simple Shoulder Test, and pain visual analog scale. Results: Of the 22 patients who met our criteria, 5 (22.7%) were lost to follow-up, leaving 17 (77.2%) available for follow-up with a mean ± SD age of 31.7 ± 12.9 years. Among these patients, 16 (94.1%) underwent 1.6 ± 0.73 ipsilateral shoulder operations (range, 1-3) before undergoing the Latarjet procedure. Preoperative indications for surgery included recurrent instability with bone loss in all cases. After a mean follow-up of 40.2 ± 22.9 months, patients experienced significant score improvements in the American Shoulder and Elbow Surgeons form, Simple Shoulder Test, and pain visual analog scale ( P < .05 for all). There were 2 reoperations (11.8%). There were no cases of neurovascular injuries or other complications. Conclusion: Female patients with recurrent shoulder instability with glenoid bone loss can be successfully treated with the Latarjet procedure, with outcomes similar to those of male patients in the previously published literature. This information can be used to counsel female patients with recurrent instability with significant anterior glenoid bone loss.

Recurrent Anterior Shoulder Instability

Background: Recent studies have demonstrated equivalent short-term results when comparing arthroscopic versus open anterior shoulder stabilization. However, none have evaluated the long-term clinical outcomes of patients after arthroscopic or open anterior shoulder stabilization, with inclusion of an assessment of preoperative glenoid tracking. Purpose: To compare long-term clinical outcomes of patients with recurrent anterior shoulder instability randomized to open and arthroscopic stabilization groups. Additionally, preoperative magnetic resonance imaging (MRI) studies were used to assess whether the shoulders were “on-track” or “off-track” to ascertain a prediction of increased failure risk. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Follow-up assessments were performed at minimum 15-year follow-up using established postoperative evaluations. Clinical failure was defined as any recurrent dislocation postoperatively or subjective instability. Preoperative MRI scans were obtained to calculate the glenoid track and designate shoulders as on-track or off-track. These results were then correlated with the patients’ clinical results at their latest follow-up. Results: Of 64 patients, 60 (28 arthroscopic and 32 open) were contacted or examined for follow-up (range, 15-17 years). The mean age at the time of surgery was 25 years (range, 19-42 years), while the mean age at the time of this assessment was 40 years (range, 34-57 years). The rates of arthroscopic and open long-term failure were 14.3% (4/28) and 12.5% (4/32), respectively. There were no differences in subjective shoulder outcome scores between the treatment groups. Of the 56 shoulders, with available MRI studies, 8 (14.3%) were determined to be off-track. Of these 8 shoulders, there were 2 surgical failures (25.0%; 1 treated arthroscopically, 1 treated open). In the on-track group, 6 of 48 had failed surgery (12.5%; 3 open, 3 arthroscopic [ P = .280]). Conclusion: Long-term clinical outcomes were comparable at 15 years postoperatively between the arthroscopic and open stabilization groups. The presence of an off-track lesion may be associated with a higher rate of recurrent instability in both cohorts at long-term follow-up; however, this study was underpowered to verify this situation.

Background There are few studies reporting long-term rotator cuff integrity following repair. The present study reports a case series of surgically repaired supraspinatus tendons followed up with clinical outcomes and ultrasound imaging after an average of 16 years. Methods The prospectively studied clinical outcomes at short-, medium- and long-term follow-up in 27 shoulders in 25 patients treated with arthroscopic subacromial decompression and mini-open rotator cuff repair have been reported previously. The functional outcomes scores recorded were the University of California Los Angeles (UCLA), American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) measures. These patients then underwent an ultrasound scan with respect to the long-term assessment of the shoulder and the integrity of the repair. Results A recurrent tear was noted in 37% of patients at 16.25 years after surgery, of which 50% were small. Two patients required repeat surgery. Patients had a mean UCLA score of 30, an ASES score of 91.3 and a SST score of 9.5 with a 85% level of satisfaction with surgery. Patients with a recurrent tear had outcome scores equivalent to those with an intact cuff with no significant pain. No independent risk factors were identified as predictors for recurrent tear. Conclusions Patients showed sustained benefit and satisfaction at long-term follow-up despite a 37% recurrence of full-thickness supraspinatus tear.

Background and Objectives: The all-arthroscopic Latarjet (aL) procedure was introduced to manage recurrent shoulder instability. Our study aimed to report the outcomes of aL procedures with the Rowe, University of California-Los Angeles (UCLA), simple shoulder test (SST) scores, and range of motion (ROM) in external rotation at a minimum follow-up of 2 years. Material and Methods: A total of 44 patients presenting recurrent shoulder instability were managed with aL procedure. Clinical outcomes were assessed at a mean follow-up of 29.6 ± 6.9 months. The postoperative active ROM was measured and compared with the contralateral shoulder. The Rowe, UCLA, and SST scores were administered preoperatively and postoperatively. Results: No patients experienced infections or neuro-vascular injuries. Seven (15%) patients required revision surgery. After surgery, the external rotation was statistically lower compared to the contralateral shoulder, but it improved; clinical outcomes also improved in a statistically significant fashion. Conclusions: The aL produced good results in the management of recurrent shoulder instability, but the complication rate was still high even in the hands of expert arthroscopist.

Glenoid Reconstruction

Objectives: Revision surgeries after prior shoulder stabilization are known to have worse outcomes as compared to their primary counterparts. To date, no studies have looked at the utility of arthroscopic anatomic glenoid reconstruction (AAGR) as a revision surgery. The purpose of this study was to assess the clinical outcomes of primary versus revision AAGR for anterior shoulder instability with bone loss. Methods: We performed a retrospective review on consecutive patients with prospectively collected data who underwent AAGR from 2012 to 2018. Patients who received AAGR for anterior shoulder instability with bone loss and had a minimum follow-up of two years were included. Exclusion criteria included patients with rotator cuff pathology, multidirectional instability and glenoid fractures. There were 68 patients (48 primary and 20 revision) who met inclusion/exclusion criteria. Our primary outcome was measured using the Western Ontario Shoulder Instability Index (WOSI) and Disabilities of Arm, Shoulder, Hand (DASH) scores. Secondary outcomes included post-operative complications and post-operative recurrent instability. Results: The primary group showed a significant improvement in most-recent post-operative WOSI from 62.7 to 20.7 (P<0.001, α=0.05) and in DASH from 26.89 to 6.7 (p<0.001, α=0.05). The revision group also showed a significant improvement in WOSI from 71.5 to 34.6 (p<0.001, α=0.05) and in DASH from 39.5 to 17.0 (p<0.05, α=0.05). When comparing between groups, the revision group had worse WOSI scores (34.6) at most recent follow-up compared to the primary group (20.7); p<0.05. The most-recent DASH scores also showed the revision group (17.0) having worse outcomes than the primary group (6.7); p<0.05. Important to note that the minimal clinically important difference (MCID) was met for WOSI (MCID=10.4) but not DASH (MCID=10.83). There were no post-operative reports of instability in either group. For complications, one hardware failure (suture anchor) was seen in the primary group, and two hardware removals were seen in the revision group. Conclusions: While patient reported scores indicated worse outcomes in the revision group, the significant clinical improvement in DASH and WOSI, along with the lack of recurrent instability provides evidence that AAGR is a suitable option for revision patients.

Capsular Shift

Objectives: Arthroscopic Bankart repair has become the surgical procedure of choice for many in the United States, over the Latarjet in Europe, for first time anterior shoulder instability with minimal bone loss, less than 20%. However, high recurrence rates in contact athletes have led many to proceed with open type procedures. Our purpose was to compare failure rates and functional outcomes of the arthroscopic inferior capsular shift in contact and non-contact athletes. We hypothesized that contact and non-contact athletes would exhibit excellent functional outcomes and return to sport with low recurrence rates. Methods: A consecutive series of 69 shoulders in 61 contact and non-contact athletes underwent an arthroscopic inferior capsular shift with ≥3 suture anchors by a single surgeon (1999-2018). Thirty shoulders in 26 contact athletes (6 women; 25.3±8.1 years) and 39 shoulders in 35 non-contact athletes (7 women; 34.8±10.0 years) were included. Inclusion criteria were complete anterior inferior labral detachment (6 unit hours) and ≥2-year follow-up. Exclusion criteria included multidirectional instability, engaging Hill Sachs lesion or glenoid bone loss >30%. A modified 3-portal technique utilizing the outside-in method was employed. A conservative rehabilitation program was followed with return to sport no sooner than 3 months in non-contact, 4-5 months in contact, and 9 months in throwing athletes. Functional outcomes were measured using Constant Scores, American Shoulder and Elbow Surgeons (ASES) Score, Western Ontario Shoulder Instability Index (WOSI), Melbourne Instability Shoulder Scale (MISS), and Rowe. Forward elevation, external rotation at side and 90° abduction and internal rotation range of motion (ROM) were measured. Independent samples t-tests were used to assess differences in outcomes between contact and non-contact athletes (Bonferroni correction: p<0.006). Results: Follow-up was 11.0±3.5 years (range 2-16 years) in contact athletes and 12.2±4.3 years (range 2-21 years) in non-contact athletes (p=0.264). Contact athletes were significantly younger than non-contact athletes (p<0.0001). An average of 3.9±1.7 and 3.1±1.0 suture anchors were used in contact and non-contact groups, respectively (p=0.348). There were no significant differences in post-operative functional scores (all p>0.053) or shoulder ROM (all p>0.034) between groups. Forward flexion was 163.75±16.8° pre-operatively and 168.89±13.0° post-operatively in contact athletes (p=0.212) and 162.5±13.7° preoperatively and 170±7.7° post-operatively in non-contact athletes (p=0.005). External rotation at the side was 59.04±19.4° pre-operatively and 67.9±18.6° value post-operatively in contact athletes (p=0.094) and 52.94±25.1° pre-operatively and 62.83±14.3° post-operatively in non-contact athletes (p=0.062). External rotation at 90° abduction was 92.61±20.1° pre-operatively and 93.39±12.9° post-operatively in contact athletes (p=0.867) and 88.33±21.1° pre-operatively and 87.5±8.1° post-operatively in non-contact athletes (p=0.842).Internal rotation behind the back was to an average of T11 pre-operatively and T9 post-operatively in contact athletes (p=0.004) and L1 pre-operatively and T9 post-operatively in non-contact athletes (p=0.001).In contact and non-contact athletes, respectively, Rowe scores were 65.35±17.6 and 51.25±13.2 preoperatively and 89.22±17.6 and 96.25±12.4 post-operatively (p=0.002 and p<0.001); Constant Scores were 75.69±12.6 and 61.67±11.3 pre-operatively 85.79±19.6 and 89.71±13.6 post-operatively; ASES scores were 80.40±15.3 and 62.14±22.2 pre-operatively and 93.91±9.9 and 86.06±20.7 post-operatively (p<0.001 and p<0.001); MISS scores were 59.36±12.4 and 48.39±15.5 preoperatively and 88.20±13.5 and 75.75±19.7 post-operatively (p<0.001 and p<0.001); WOSI was 3.50±1.3 and 4.55±1.4 pre-operatively and 1.70±3.0 and 2.94±2.7 post-operatively (p=0.101 and p=0.066). Overall recurrence rate was 4.3% (3/69). Two contact athletes (2/30; 6.7%) and one non-contact athlete (1/39; 2.6%) experienced a traumatic recurrent instability event requiring revision surgery (p=0.439). These three patients underwent a revision arthroscopic inferior capsular shift with an additional 3-4 plication sutures and returned to pre-injury sports including hockey, football, skiing, and tennis without recurrence of instability at greater than 7 years following the revision surgery. Conclusions: Modified arthroscopic inferior capsular shift utilizing ≥3 suture anchors with plication sutures returns contact and non-contact athletes to sports with excellent functional outcomes, low recurrence rates (3/69), and full unrestricted ROM. While loss of ROM is a concern, particularly in overhead athletes, ROM was successfully restored in all patients, most notably in external rotation at 90° abduction. We recommend a modified arthroscopic inferior capsular shift with plication sutures as the primary procedure in all athletes with anterior instability with less than 30% bone loss excluding those with high Beighton scores rather than a Latarjet.

Background: Arthroscopic bone marrow stimulation (BMS) is considered the first-line treatment for osteochondral lesions of the talus (OLTs). However, the long-term stability of the clinical success of BMS remains unclear. Purpose: To investigate the long-term clinical outcomes among patients who underwent BMS for OLT and to identify prognostic factors for the need for revision surgery. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was performed on 202 ankles (189 patients) that were treated with BMS for OLT and had a minimum follow-up of 10 years. The visual analog scale for pain, American Orthopaedic Foot & Ankle Society ankle-hindfoot score, and the Foot and Ankle Outcome Score (FAOS) were assessed by repeated measures analysis of variance. Prognostic factors associated with revision surgery were evaluated with Cox proportional hazard regression models and log-rank tests. Results: The mean lesion size was 105.32 mm2 (range, 19.75-322.79); 42 ankles (20.8%) had large lesions (≥150 mm2). The mean visual analog scale for pain improved from 7.11 ± 1.73 (mean ± SD) preoperatively to 1.44 ± 1.52, 1.46 ± 1.57, and 1.99 ± 1.67 at 1, 3 to 6, and ≥10 years, respectively, after BMS ( P < .001). The mean ankle-hindfoot score also improved, from 58.22 ± 13.57 preoperatively to 86.88 ± 10.61, 86.17 ± 10.23, and 82.76 ± 11.65 at 1, 3 to 6, and ≥10 years after BMS ( P < .001). The FAOS at the final follow-up was 82.97 ± 13.95 for pain, 81.81 ± 14.64 for symptoms, 83.49 ± 11.04 for activities of daily living, 79.34 ± 11.61 for sports, and 78.71 ± 12.42 for quality of life. Twelve ankles underwent revision surgery after a mean 53.5 months. Significant prognostic factors associated with revision surgery were the size of the lesion (preoperative magnetic resonance imaging measurement ≥150 mm2; P = .014) and obesity (body mass index ≥25; P = .009). Conclusion: BMS for OLT yields satisfactory clinical outcomes at a mean follow-up of 13.9 years. The success of the surgery may depend on the lesion size and body mass index of the patient.

Overhead Athletes

Background: Athletes of all sports often have shoulder instability, most commonly as anterior shoulder instability (ASI). For overhead athletes (OHAs) and those participating in throwing sports, clinical and surgical decision making can be difficult owing to a lack of long-term outcome studies in this population of athletes. Purpose/Hypothesis: To report presentation characteristics, pathology, treatment strategies, and outcomes of ASI in OHAs and throwers in a geographic cohort. We hypothesized that OHAs and throwers would have similar presenting characteristics, management strategies, and clinical outcomes but lower rates of return to play (RTP) when compared with non-OHAs (NOHAs) and nonthrowers, respectively. Study Design: Cohort study; Level of evidence, 3. Methods: An established geographic medical record system was used to identify OHAs diagnosed with ASI in the dominant shoulder. An overall 57 OHAs with ASI were matched 1:2 with 114 NOHAs with ASI. Of the OHAs, 40 were throwers. Sports considered overhead were volleyball, swimming, racquet sports, baseball, and softball, while baseball and softball composed the thrower subgroup. Records were reviewed for patient characteristics, type of sport, imaging findings, treatment strategies, and surgical details. Patients were contacted to collect Western Ontario Shoulder Instability index (WOSI) scores and RTP data. Statistical analysis compared throwers with nonthrowers and OHAs with NOHAs. Results: Four patients, 3 NOHAs and 1 thrower, were lost to follow-up at 6 months. Clinical follow-up for the remaining 167 patients (98%) was 11.9 ± 7.2 years (mean ± SD). Of the 171 patients included, an overall 41 (36%) NOHAs, 29 (51%) OHAs, and 22 (55%) throwers were able to be contacted for WOSI scores and RTP data. OHAs were more likely to initially present with subluxations (56%; P = .030). NOHAs were more likely to have dislocations (80%; P = .018). The number of instability events at presentation was similar. OHAs were more likely to undergo initial operative management. Differences in rates of recurrent instability were not significant after initial nonoperative management (NOHAs, 37.1% vs OHAs, 28.6% [ P = .331] and throwers, 21.2% [ P = .094]) and surgery (NOHAs, 20.5% vs OHAs, 13.0% [ P = .516] and throwers, 9.1% [ P = .662]). Rates of revision surgery were similar (NOHAs, 18.0% vs OHAs, 8.7% [ P = .464] and throwers, 18.2% [ P > .999]). RTP rates were 80.5% in NOHAs, as compared with 71.4% in OHAs ( P = .381) and 63.6% in throwers ( P = .143). Median WOSI scores were 40 for NOHAs, as compared with 28 in OHAs ( P = .425) and 28 in throwers ( P = .615). Conclusion: In a 1:2 matched comparison of general population athletes, throwers and OHAs were more likely to have more subtle instability, as evidenced by higher rates of subluxations rather than frank dislocations, when compared with NOHAs. Despite differences in presentation and the unique sport demands of OHAs, rates of recurrent instability and revision surgery were similar across groups. Similar outcomes in terms of RTP, level of RTP, and WOSI scores were achieved for OHAs and NOHAs, but these results must be interpreted with caution given the limited sample size.

ABSTRACT To describe the ‘mini-Max’ approach to labrum repair using non-absorbable 2.4-mm knotless suture anchors and report objective clinical outcomes with a large single-surgeon cohort. Level 3 retrospective case series. A retrospective review was conducted to report the use and allocation of non-absorbable 2.4-mm knotless suture anchors during ‘mini-Max’ labral repair from 2015 to 2018. Descriptive analysis of the labral damage severity, size and number of anchors used to arthroscopically repair the acetabular labrum was performed. Paired-samples t-tests were performed to evaluate whether preoperative and 1-year follow-up patient-reported outcomes (PROs) were statistically significant. An analysis of variance was performed comparing PROs with categorized number of labral anchors. A total of 390 patients were queried in this study, with 330 (85%) diagnosed intraoperatively with acetabular labral tears. A total of 245 patients (137 females and 108 males) with a mean age of 30.1 ± 11.6 years (mean ± SD) at the time of surgery underwent ‘mini-Max’ labral refixation. Of the 245 labral tears, 88 (35.9%) were graded as mild, 113 (46.1%) as moderate and 44 (18.0%) as severe. Labral repairs required an average of 2.1 ± 0.67 anchors across all patients included. Forty-one repairs (16.7%) required one anchor, 139 (56.7%) required two anchors, 63 (25.7%) required three anchors and 2 (0.8%) required four anchors. Significant improvements were reported for all PROs (P ≤ .001) at a minimum of 1-year follow-up. Arthroscopic ‘mini-Max’ labral repair using non-absorbable knotless suture anchors is a safe and effective technique for improving the lives of patients suffering from symptomatic acetabular labrum tears.

INTRODUCTION: The treatment of adolescent shoulder instability can be a challenging problem, with multiple patient and radiographic risk factors for recurrent instability. Although glenoid bone loss has been well described, humeral bone loss has gained more recent attention. The purpose of this study is to evaluate the incidence and clinical outcomes of “off track” shoulder lesions and their association with clinical outcomes. METHODS: A retrospective IRB approved study was performed to identify patients less than 19 years of age treated with isolated arthroscopic anterior labral repair for unidirectional shoulder instability. Radiographic measurements of glenoid diameter, % glenoid bone loss, glenoid track, hill-sachs interval (HIS), HS/glenoid track ratio, and intact anterior articular angle (IAAA) were performed for all patients with magnetic resonance imaging (MRI). All patients were contacted at final follow-up to collect outcome scores (PASS and SANE scores, activity level). A multivariable logistic regression analysis was performed to identify predictors of revision surgery or subjective instability (RI). RESULTS: 86 patients were identified to meet inclusion criteria and 69 of these patients, 53 males and 16 females with a median age of 16 years [15, 17], had minimum 1-year clinical follow-up and were included in assessment of clinical outcomes and multivariable analysis. 12 patients (17%) had revision surgery and 10 patients had subjective instability without revision (14%) In univariate analysis (Table 1), patient height was the only patient factor which was significantly different between the revision/instability (RI) cohort and the non-revision/instability (NRI) cohort. All 86 patients were included in radiographic analysis. Intra- and inter-rater reliability (ICCs) for radiographic measurements are presented in table 2. Agreement was good and excellent for all measurements with the exception of inter-rater reliability of IAAA. Multivariable regression analysis demonstrated that HS/glenoid track ratio was not a predictor for RI. PASS and SANE scores at final follow-up were significantly lower in the RI cohort (79.5 and 70) respectively) as compared to the NRI cohort (94 and 90 respectively), p<0.001. 42 patients (69%) returned to the same or higher level of sports following surgery and this was no different between RI and NRI cohorts. CONCLUSIONS: 31% of adolescent patients in our cohort experienced RI following arthroscopic bankart repair and this was associated with inferior PASS and SANE scores. Off-track lesions were not predictive of failure with primary repair.
