Background: Anterior shoulder instability can be successfully treated using Latarjet procedures, although a small proportion of patients report unexplained pain. Purpose/Hypothesis: The purpose was to report the prevalence and characteristics of patients with unexplained pain without recurrent instability after open Latarjet procedures and to determine whether screw removal can alleviate pain. The hypothesis was that unexplained pain without recurrent instability might be due to soft tissue impingements against the screw heads and that the removal of screws would alleviate or reduce pain. Study Design: Case series; Level of evidence, 4. Methods: We retrospectively reviewed the clinical and radiographic records of 461 consecutive shoulders treated by open Latarjet procedures for anterior instability between 2002 and 2014. Unexplained anterior pain was present in 21 shoulders (4.6%) and treated by screw removal at 29 ± 37 months (mean ± SD). Postoperative assessment at >12 months after screw removal included complications, visual analog scale for pain (pVAS), subjective shoulder value, Rowe score, Walch-Duplay score, and ranges of motion. The study cohort comprised the shoulders of 20 patients (9 women, 11 men) aged 25 ± 6 years (median, 25 years; range, 16-34 years) at screw removal and involved the dominant arm in 13 (62%) shoulders. Results: Screw removal alleviated pain completely in 14 shoulders (67%; pVAS improvement, 6.4 ± 1.8; median, 6; range, 3-8) and reduced pain in the remaining 7 (33%; pVAS improvement, 2.4 ± 1.4; median, 2; range, 1-5). At 38 ± 23 months after screw removal, 2 recurrences of instability unrelated to screw removal occurred. The subjective shoulder value was 79% ± 22% (median, 90%; range, 0%-95%); Rowe score, 85 ± 20 (median, 95; range, 30-100); and Walch-Duplay score, 82 ± 19 (median, 85; range, 25-100). Mobility improved in active forward elevation (171°± 14°), external rotation with the elbow at the side (61°± 12°), and external rotation with the arm at 90° of abduction (67°± 13°) and especially in internal rotation, with only 2 shoulders (10%) limited to T12 spine segment. Conclusion: The present findings confirm that unexplained anterior pain after Latarjet procedures can be related to the screws used to fix bone blocks, which can safely be alleviated or reduced by screw removal.

Capsulolabral Reconstruction

Background: The correlation between isokinetic internal and external rotation (IR and ER) strength and functional outcomes in patients with anterior shoulder instability treated by arthroscopic capsulolabral reconstruction (ACR) has not been studied. Purpose: To analyze isokinetic IR and ER strength and their correlation with clinical outcomes in patients with anterior shoulder instability treated by ACR. Study Design: Case series; Level of evidence, 4. Methods: Between January 2004 and June 2015, a total of 104 patients who underwent ACR for anterior shoulder instability were analyzed. The mean peak torque (PT) in IR (IRPT) and ER (ERPT), PT deficit (PTD; %) relative to the opposite healthy shoulder, and PT ratio (PTR; ERPT/IRPT) were calculated before and 1 year after surgery. Functional scores were evaluated before surgery and at every follow-up visit. Recurrence and postoperative apprehension during ER at 90° of arm abduction were evaluated at 1 year and the final follow-up (76.6 ± 64.4 months). Results: IR and ER strength were measured for 68 of 104 patients at 1 year after surgery. ERPT and IRPT were less on the involved side than on the uninvolved side before surgery (0.29 ± 0.10 vs 0.33 ± 0.10 N·m/kg, respectively, for ERPT [ P = .002]; 0.36 ± 0.14 vs 0.41 ± 0.16 N·m/kg, respectively; for IRPT [ P = .01]). At 1 year after surgery, IRPT on the involved side recovered (0.40 ± 0.20 N·m/kg), whereas ERPT remained weak (0.30 ± 0.13 N·m/kg) relative to the baseline value. PTD in IR (PTDIR) improved to 2.2% ± 24.4% ( P = .012), whereas PTD in ER (PTDER) showed no improvement (13.5% ± 13.8%; P = .569). PTR on the involved side improved from 1.07 ± 1.71 to 0.86 ± 0.23 at 1 year ( P < .001). All functional scores improved significantly at the final follow-up. At 1 year, 9 of 68 (13.2%) patients showed positive apprehension. PTDIR and PTDER on the involved side were worse in patients with positive apprehension than in those with negative apprehension ( P = .039 and .014, respectively). PTDER was worse than PTDIR in patients with positive apprehension at 1 year ( P = .022). Conclusion: For those with anterior shoulder instability, preoperative IR and ER strength of the involved shoulder were lower than those of the uninvolved shoulder. IRPT recovered, whereas ERPT remained weak after ACR. To prevent positive apprehension after surgery, IR and ER strengthening exercises are important, with more emphasis on exercises for ER.

Background: The optimal revision surgery for failed primary arthroscopic capsulolabral repair (ACR) has yet to be determined. Revision ACR has shown promising results. Purpose: To compare the functional, strength, and radiological outcomes of revision ACR and primary ACR for anterior shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: Between March 2007 and April 2017, a total of 85 patients underwent ACR (revision: n = 23; primary: n = 62). Functional outcome scores and positive apprehension signs were evaluated preoperatively, at 1 year, and then annually. Isokinetic internal and external rotation strengths were evaluated preoperatively and at 1 year after surgery. Results: The mean follow-up was 36.5 ± 10.2 months (range, 24-105 months). There was no significant difference between the revision and primary groups in the glenoid bone defect size at the time of surgery (17.3% ± 4.8% vs 15.4% ± 5.1%, respectively; P = .197). At the final follow-up, no significant differences were found in the American Shoulder and Elbow Surgeons score (97.6 ± 3.1 vs 98.0 ± 6.2, respectively; P = .573), Western Ontario Shoulder Instability Index score (636.7 ± 278.1 vs 551.1 ± 305.4, respectively; P = .584), or patients with a positive apprehension sign (17.4% [4/23] vs 11.3% [7/62], respectively; P = .479) between the revision and primary groups. There was no significant difference between the revision and primary groups for returning to sports at the same preoperative level (65.2% vs 80.6%, respectively; P = .136) and anatomic healing failure at 1 year after surgery (13.0% vs 3.2%, respectively; P = .120). Both groups recovered external rotation strength at 1 year after surgery (vs before surgery), although the strength was weaker than in the uninvolved shoulder. In the revision group, a larger glenoid bone defect was significantly related to a positive apprehension sign (22.0% ± 3.8%) vs a negative apprehension sign (16.0% ± 3.2%; cutoff = 20.5%; P = .003). Conclusion: In patients with moderate glenoid bone defect sizes (10%-25%), clinical outcomes after revision ACR were comparable to those after primary ACR. However, significant glenoid bone loss was related to a positive remaining apprehension sign in the revision group. Surgeons should consider these findings when selecting their revision strategy for patients with failed anterior shoulder stabilization.

Background: Anterior glenoid reconstruction with fresh distal tibia allograft (DTA) has been described for management of recurrent shoulder instability, with encouraging early outcomes; however, no comparative data with the Latarjet procedure are available. Purpose: The purpose of this study was to compare the clinical outcomes between patients undergoing DTA and a matched cohort of patients undergoing Latarjet. Study Design: Cohort study; Level of evidence, 3. Methods: A review was conducted of prospectively collected data for patients with a minimum 15% anterior glenoid bone loss who underwent shoulder stabilization via either the DTA or Latarjet procedure and had a minimum follow-up of 2 years. Consecutive patients undergoing DTA were matched in a 1-to-1 format to patients undergoing Latarjet by age, body mass index, history of contact sports, and number of previous shoulder operations. Patients were evaluated pre- and postoperatively with a physical examination and the following outcome assessments: Simple Shoulder Test, visual analog scale, American Shoulder and Elbow Surgeons, Western Ontario Shoulder Instability Index, and Single Assessment Numeric Evaluation. Complications, reoperations, and episodes of recurrent instability were analyzed. Statistical analysis was performed with Student t tests, with P < .05 considered significant. Results: A total of 100 patients (50 Latarjet, 50 DTA) with a mean ± SD age of 25.6 ± 6.1 years were analyzed at 45 ± 20 months (range, 24-111) after surgery. Thirty-two patients (64%) in each group underwent prior ipsilateral shoulder surgery (range, 1-3). Patients undergoing DTA had significantly greater glenoid bone loss defects when compared with patients undergoing Latarjet (28.6% ± 7.4% vs 22.4% ± 10.3%, P = .001). Patients in both groups experienced significant improvements in all outcome scores after surgery ( P < .05 for all). No significant differences were found in postoperative scores between the Latarjet and DTA groups: visual analog scale (0.67 ± 0.97 vs 1.83 ± 2.31), American Shoulder and Elbow Surgeons (91.06 ± 8.78 vs 89.74 ± 12.66), Western Ontario Shoulder Instability Index (74.30 ± 21.84 vs 89.69 ± 5.50), or Single Assessment Numeric Evaluation (80.68 ± 7.21 vs 90.08 ± 13.39) ( P > .05 for all). However, patients in the Latarjet group had superior Simple Shoulder Test outcomes ( P = .011). There were 10 complications (10%) for the entire cohort, including 5 in the Latarjet group (3 of which required reoperation) and 5 in the DTA group (3 of which required reoperation). The overall recurrent instability rate was 1% (1 patient). Conclusion: Fresh DTA reconstruction for recurrent anterior shoulder instability results in a clinically stable joint with similar clinical outcomes as the Latarjet procedure. Longer-term studies are needed to determine if these results are maintained over time.

Background: Shoulder instability has been well described in young men; however, few studies have specifically evaluated the pathoanatomy and unique spectrum of injuries in women with shoulder instability. Purpose: To describe the pathoanatomy of operative shoulder instability in a collegiate female cohort. Study Design: Case series; Level of evidence, 4. Methods: The authors performed a retrospective analysis of a consecutive series of female students at a National Collegiate Athletic Association Division I military service academy treated operatively for shoulder instability by a single surgeon between September 2008 and September 2014. Preoperative data collected included patient age, sport, mechanism of injury, number and frequency of dislocations, direction of instability, and co-occurring surgical abnormalities at the time of arthroscopy. Outcome variables included recurrent instability after surgery and need for revision. Results: Thirty-six female student athletes with an average age of 20 years (range, 18-22 years) were included. The majority of instability events were traumatic in nature (69%), and 61% of the total events were subluxations. Rugby was the most common sport for experiencing instability (7 patients), followed by obstacle course training (6 patients). Thirty-two patients (89%) reported multiple instability events, averaging 4 per shoulder. The primary direction of instability was anterior in 26, combined anterior and posterior in 7, and 3 met criteria for multidirectional instability. At the time of surgery, 26 patients (72%) had a Bankart tear, 9 (25%) had a posterior labral tear, and 5 (14%) had superior labrum anterior to posterior tears. Nine patients (25%) were found to have humeral avulsion of the glenohumeral ligament (HAGL) lesions, 7 (19%) had partial-thickness articular-sided rotator cuff tears, and only 1 patient (3%) had evidence of true attritional glenoid bone loss. Hill-Sachs lesions were found in 16 patients (44%). Recurrent instability occurred in 9 patients (25%) following arthroscopic stabilization, and revision surgery was performed in 6 (17%). Conclusion: Shoulder instability in female athletes presents commonly as multiple subluxation events. While soft tissue Bankart lesions were found in numbers equal to those in previous studies include both sexes, bony Bankart lesions were less common in women. Finally, the presence of combined anterior and posterior labral tears and HAGLs in women was more common than previously reported.

Background: Although numerous studies have reported on the redislocation rate and functional results of arthroscopic treatment for anterior shoulder instability in athletes, they have not disclosed outcomes in the high-risk group of elite handball players. Purpose: To investigate the postoperative outcomes of arthroscopic treatment for anterior shoulder instability as well as the return-to-sport (RTS) rate in professional handball players. Study Design: Case series; Level of evidence, 4. Methods: Involved in this study were 44 competitive handball players (47 shoulders) who underwent arthroscopic anterior capsulolabral reconstruction between 2010 and 2018 and had a minimum follow-up of 24 months. After surgery, patients completed a questionnaire that collected Rowe and American Shoulder and Elbow Surgeons (ASES) scores and RTS data, and we compared these results with their preoperative scores. We also compared results according to the following subgroups: true dislocations versus recurrent subluxations, younger (<20 years) versus older (≥20 years) age, male versus female sex, and shorter versus longer duration of instability. Statistical analysis included the paired-samples t test and nonparametric Fisher exact test. Results: The mean follow-up period was 52.2 ± 21.4 months. There were 4 shoulders (9%) with recurrent instability. There were significant preoperative to postoperative improvements in the mean Rowe score (from 45.2 to 91.8) and mean ASES score (from 70.6 to 95.7) ( P < .001 for both). Overall, the RTS rate was 83%, and 64% (30/47 shoulders) were able to return to their preinjury level. The RTS rate was significantly lower in the younger players than in the older players (46% vs 86%, respectively; P = .005). Conclusion: The study results indicated that handball players with anterior shoulder instability can be treated using arthroscopic labral reconstruction successfully and 83% of the athletes were able to RTS activity. The handball players aged ≥20 years returned to their preinjury level of sport at a higher rate than did those aged <20 years.

Recurrent Anterior Shoulder Instability

Background The effectiveness of arthroscopic thermal capsulorrhaphy in the prevention of recurrent instability in primary anterior stabilization is undetermined. Purpose To determine if patients with recurrent anterior shoulder instability who have labral repair plus arthroscopic thermal capsulorrhaphy have better outcomes than those with labral repair alone. Study Design Cohort study; Level of evidence, 3. Method There were 72 patients who underwent arthroscopic anterior shoulder stabilization with Suretac II tacks (n = 32) during 1996 to 1999 or with Suretac II tacks plus arthroscopic radiofrequency capsular shrinkage (n = 40) from 1999 to 2002. Standardized patient-determined and examiner-determined outcome measures were obtained preoperatively and at 3, 6, 12, and 24 months postoperatively. Statistical analyses included a Kaplan-Meier analysis of time to recurrent instability. Results Of the 72 patients, 66 had complete follow-up, including 28 patients treated with the Suretac stabilization and 38 patients with the Suretac plus radiofrequency shrinkage, for a mean follow-up of 58 and 30 months, respectively. All patients had a Bankart lesion. Both groups had similar results with respect to patient-determined and examiner-determined outcome measures. The only adverse outcome was postoperative recurrent instability in 6 of 28 cases in the Suretac group alone and 8 of 38 cases in the Suretac-plus-shrinkage group. Most recurrent instability occurred between 6 and 24 months. Kaplan-Meier analysis for time to recurrent instability showed no differences in the rate of instability recurrence between the 2 groups. Conclusion Arthroscopic thermal capsulorrhaphy neither enhanced nor impaired the outcomes of arthroscopic labral repair with biodegradable tacks in patients with primary recurrent anterior shoulder instability.

Level Of Evidence

Background: The Latarjet procedure is often used to address off-track Hill-Sachs lesions (OFF-HS) in shoulders with anterior instability. There are concerns as to whether the Latarjet procedure is able to convert all OFF-HS into on-track Hill-Sachs lesions (ON-HS) and whether this limitation could explain the cases of recurrent postoperative instability. Hypothesis: Latarjet surgery converts many preoperative OFF-HS lesions, but not all of them, and there is a difference in the failure rate between shoulders with converted lesions and those with persistent OFF-HS lesions. Study Design: Case series; Level of evidence, 4. Methods: Patients with anterior shoulder instability and an OFF-HS lesion treated with an arthroscopic classic Latarjet procedure between January 2010 and September 2017 were retrospectively evaluated. Patients with moderate or severe shoulder arthrosis, rotator cuff tears, or age older than 50 years were excluded. Glenoid track (GT), HS, HS interval (HSI), and the difference between HSI and GT (ΔHSI-GT) were measured preoperatively. A postoperative computed tomography scan and a clinical evaluation, including the Rowe and Western Ontario Shoulder Instability scores, were performed at a minimum 1- and 2-year follow-up, respectively. Postoperatively, 2 groups of patients were obtained: (1) patients with postoperative persistent OFF-HS; (2) patients with postoperative ON-HS. Clinical and imaging data were compared between the 2 groups. Results: A total of 51 patients (n = 51 shoulders), with a mean age of 29.8 ± 8.4 years (range, 15-50 years), met the inclusion criteria. Six shoulders (11.8%) still showed OFF-HS lesions despite Latarjet surgery. There were no postoperative dislocations, but 3 patients reported subluxations. The subluxation rate was significantly higher in the postoperative persistent OFF-HS group (2 [33%] vs 1 [2.2%]; P = .033). There was a wider preoperative HSI (29.8 ± 2.4 mm vs 22.9 ± 3.5 mm; P < .001) and a larger preoperative ΔHSI-GT (12.2 ± 3.8 mm vs 4.82 ± 3.2 mm; P < .001) in the persistent OFF-HS group. A receiver operating characteristic curve was performed based on preoperative ΔHSI-GT values. A preoperative ΔHSI-GT value ≥7.45 mm predicted a persistent OFF-HS after Latarjet surgery (sensitivity, 100%; specificity, 87%; positive predictive value, 50%; and negative predictive value, 100%). Conclusion: Latarjet surgery converted many preoperative OFF-HS lesions into ON-HS lesions, but not all of them. Six patients (11.8%) retained an OFF-HS and had a statistically significantly higher failure rate after Latarjet surgery compared with those with postoperative ON-HS lesions. Because there were few postoperative OFF-HS lesions and few recurrences, findings are statistically fragile and should be confirmed with larger series.

Abstract Background Revision surgery after the Latarjet procedure is a rare and challenging surgical problem, and various bony or capsular procedures have been proposed. This systematic review examines clinical and radiographic outcomes of different procedures for treating persistent pain or recurrent instability after a Latarjet procedure. Methods A systematic review of the literature was performed using the Medline, Cochrane, EMBASE, Google Scholar and Ovid databases with the combined keywords “failed”, “failure”, “revision”, “Latarjet”, “shoulder stabilization” and “shoulder instability” to identify articles published in English that deal with failed Latarjet procedures. Results A total of 11 studies (five retrospective and six case series investigations), all published between 2008 and 2020, fulfilled our inclusion criteria. For the study, 253 patients (254 shoulders, 79.8% male) with a mean age of 29.6 years (range: 16–54 years) were reviewed at an average follow-up of 51.5 months (range: 24–208 months). Conclusions Eden–Hybinette and arthroscopic capsuloplasty are the most popular and safe procedures to treat recurrent instability after a failed Latarjet procedure, and yield reasonable clinical outcomes. A bone graft procedure and capsuloplasty were proposed but there was no clear consensus on their efficacy and indication.

Ultrasound Parameters

Background: Ultrasound is an essential tool for diagnosing shoulder disorders. However, the role of ultrasound in assessing and diagnosing adhesive capsulitis has not been fully studied. Purpose: To evaluate the ultrasound features of adhesive capsulitis and estimate the correlations between clinical impairment and ultrasound parameters. Study Design: Case series; Level of evidence, 4. Methods: A total of 61 patients with clinically diagnosed unilateral adhesive capsulitis were retrospectively reviewed using high-resolution ultrasound. To compare ultrasound parameters, we performed ultrasound examinations on both affected and unaffected shoulders. Ultrasound parameters, including thickness of the coracohumeral ligament (CHL), rotator interval (RI), axillary recess (AR), hypervascularity of the RI, and effusion of the long head of the biceps tendon sheath, were measured. Passive range of motion (PROM), visual analog scale for pain, and the Shoulder Pain and Disability Index were used for clinical assessment. Results: The CHL, the RI, and the AR in affected shoulders were significantly thicker than in unaffected shoulders ( P < .05). CHL thickness in affected shoulders was significantly correlated with PROM limitation, which included forward elevation, abduction, external rotation (ER), and internal rotation (IR) ( P < .05). AR thickness correlated with passive forward elevation limitation and passive IR limitation ( P < .05). The CHL was significantly thicker in stage 2 compared with stage 1, and the RI was thicker in stage 2 compared with stage 3. The diagnostic cutoff values for adhesive capsulitis were 2.2 mm for CHL thickness (77% sensitivity, 91.8% specificity) and 4 mm for AR thickness (68.9% sensitivity, 90.2% specificity). Conclusion: The ultrasound parameters associated with structural changes were correlated with clinical characteristics of adhesive capsulitis. Thickened CHL, RI, and AR were observed in affected shoulders. The cutoff values of 2.2 mm for CHL thickness and 4 mm for AR thickness can be used as cutoff diagnostic values for adhesive capsulitis.
