Background The open Bankart technique for posttraumatic recurrent anterior instability has become the procedure of choice for patients who do not respond to nonoperative treatment. Hypothesis The open Bankart procedure renders stable and well-functioning shoulders in the long term in a large proportion of patients. Study Design Retrospective follow-up study with independent reexaminers. Methods Fifty-four patients (54 shoulders) with symptomatic, posttraumatic, recurrent anterior shoulder instability underwent an open Bankart reconstruction procedure with suture anchors. All of the patients had a Bankart lesion. Forty-seven patients (87%) were reexamined by independent observers at a mean follow-up period of 69 months (range, 48 to 114). Results The recurrence rate, including both dislocations and subluxations, was 17% (8 of 47). The median Rowe score was 90 points (range, 24 to 100) at the follow-up, and the median Constant score was 88.5 points (range, 41 to 100). External rotation in abduction was a median of 90° (range, 25° to 125°) in the involved shoulders, as compared with 97.5° (80° to 125°) in the noninjured shoulders (P < 0.0001). Conclusions We conclude that, in the long term, the open Bankart procedure resulted in an unexpectedly high number of patients with failure in terms of stability. These results emphasize the importance of performing long-term follow-up studies after surgical reconstruction for unidirectional, posttraumatic, anterior shoulder instability using any type of technique.

Background: The implant-free, autologous, iliac crest bone graft procedure (J-bone graft) for the treatment of anterior shoulder instability shows low rates of recurrent dislocations and moderate progression of instability arthropathy in the midterm follow-up. Purpose: To analyze the clinical and radiological long-term results of the J-bone graft procedure. Study Design: Case series; Level of evidence, 4. Methods: A total of 46 patients (47 shoulders) with anterior shoulder instability and a relevant bony glenoid defect who received a J-bone graft between 1993 and 2000 and who were previously subjected to a midterm follow-up (mean, 8 years) were included. In total, 34 patients and 35 shoulders (74%) were clinically and radiologically assessed after a mean follow-up of 18 years (range, 15-23 years). Patients were assessed in terms of pain, bilateral active range of motion, and strength; in addition, the Western Ontario Shoulder Instability Index (WOSI), the Rowe Score, and the Subjective Shoulder Value (SSV) were obtained. Both an apprehension test and a relocation test were performed. Radiological imaging included bilateral radiographs (true anteroposterior and axillary view) to determine the grade of instability arthropathy. Results: At final follow-up, a mean WOSI score of 295 (range, 0-1765), Rowe Score of 94 (range, 55-100), SSV of 90% (range, 20%-100%), and pain level of 0.5 (range, 0-4) were noted. Slight differences were detected in active range of motion between the affected and the contralateral side: flexion 178° vs 179° ( P = .325), abduction 177° vs 179° ( P = .225), external rotation 63° vs 67° ( P = .048), high external rotation 77° vs 82° ( P = .007), internal rotation 8.8 vs 9.4 points ( P = .017), and high internal rotation 70° vs 74° ( P = .026). No significant strength deficit of the affected side was noticed. In 1 patient, a traumatic redislocation with fracture of the bone graft was observed 6 weeks after index surgery. No further recurrences were found during the follow-up period. Negative apprehension and relocation tests were confirmed in 77% of the shoulders, while 23% were positive. At final follow-up, 9 shoulders showed no signs of instability arthropathy (26%), mild arthropathy was revealed in 22 shoulders (63%), moderate arthropathy was noted in 3 shoulders (9%), and signs of severe arthropathy were found in 1 shoulder (3%) (collective instability arthropathy score, 0.9). The collective instability arthropathy score on the contralateral side was 0.4 ± 0.8 with no instability arthropathy in 24 shoulders (69%), mild arthropathy in 8 shoulders (23%), moderate signs of arthropathy in 2 shoulders (6%), and severe arthropathy in 1 shoulder (3%) at the time of follow-up examination (collective instability arthropathy score, 0.4). The overall difference between affected shoulders and contralateral shoulders was significant ( P = .005). Conclusion: The J-bone graft procedure for the treatment of recurrent anterior shoulder instability shows excellent results regarding stability and function after a mean follow-up period of 18 years. However, the development of instability arthropathy of the affected shoulder is not prevented by this procedure.

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.

Biomechanical Effect

Background: Individual constitutional differences in glenoid shape and bone remodeling require a patient-specific and longitudinal approach to evaluate the biomechanical effects of glenoid bone grafting in patients with anterior shoulder instability. Purpose: To quantify the longitudinal, in vivo, biomechanical effects of bone grafting, bone graft remodeling, and glenoid shape in patients with anterior shoulder instability by means of patient-specific finite element models. Study Design: Descriptive laboratory study. Methods: In total, 25 shoulders of 24 patients with anterior shoulder instability and anterior glenoid bone loss underwent an arthroscopic iliac crest bone graft transfer (ICBGT) procedure with either autologous or allogenic bone. Patient-specific finite element simulations based on preoperative, postoperative, and follow-up computed tomography scans were used to quantify the bone-mediated stability ratio (SR) and the distance to dislocation. Additionally, the relationship between glenoid morphological parameters and the SR was assessed. Results: The ICBGT procedure significantly increased the SR and distance to dislocation in the 2-, 3-, and 4-o’clock directions immediately after the surgical intervention ( P < .01) in both the autograft and the allograft groups. Although the SR and distance to dislocation decreased subsequently, autografts showed long-term effects on SR and dislocation distance in the 3-o’clock direction ( P < .01) and on SR in the 4-o’clock direction ( P < .01). Allografts showed no significant effect on SR and dislocation distance in long-term follow-up ( P > .05). Overall, glenoid retroversion as well as cavity depth predicted stability in all 4 dislocation directions, with glenoid cavity depth showing the highest correlation coefficients ( R = 0.71, 0.8, 0.73, and 0.7 for 2-, 3-, 4-, and 5-o’clock, respectively). Conclusion: The autologous ICBGT procedure biomechanically improved anterior shoulder stability in long-term follow-up, whereas the use of allografts did not show any bone-mediated biomechanical effect at follow-up due to resorption. Furthermore, in addition to measurements of defect extent, the glenoid depth and version seem to be useful parameters to determine the biomechanical effect and need for glenoid bone grafting in patients with shoulder instability. Clinical Relevance: This study proposes the use of autologous bone grafts for a successful long-term stabilization effect. Additionally, this study proposes additional glenoid morphological measures to predict shoulder stability.

Recurrent Anterior Shoulder Instability

Background: Long-term results of the arthroscopic Bankart repair in patients older than 40 years are unknown and may be favorable in terms of postoperative glenohumeral arthritis as opposed to the long-term results of the open Latarjet procedure in patients older than 40 years. Purpose: To analyze our long-term results of the arthroscopic Bankart repair for recurrent anterior shoulder instability in patients older than 40 years of age and to compare these results with previously published long-term results of the Latarjet procedure in a cohort of similar age. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 35 consecutive patients (36 shoulders) with a mean age of 47 years (range, 40-69) at time of the arthroscopic Bankart repair were studied at a mean 13.2 years (range, 8-18) after surgery. Clinical and radiographic results were then compared with those of our previous study of 39 consecutive patients (40 shoulders) of a same age group who had been treated for the same pathology with an open Latarjet procedure. Results: Six shoulders (17%) sustained a recurrent shoulder dislocation after a mean 5.3 years; subluxation occurred in 3 shoulders (8%); and apprehension persisted in 3 shoulders (8%). Revision surgery was performed in 8 patients (22%): 2 Bankart and 6 open Latarjet. The relative preoperative Constant score and Subjective Shoulder Value were significantly improved ( P < .001) at final follow-up. Arthropathy of stabilization was advanced in the shoulders of 16 patients (47%) and had progressed by at least 2 grades in 21 patients (62%). There were significantly higher rates of redislocation and subluxation when compared with the open Latarjet procedure (9 vs 3; P = .037), and the mean final Subjective Shoulder Value was significantly lower in the Bankart group (86% vs 91%; P = .011). There were no significant differences in final advanced arthropathy (16 vs 14; P = .334) and revision rates (8 vs 7; P = .409) when compared with the Latarjet procedure. Conclusion: Arthroscopic Bankart repair for recurrent anterior shoulder instability in patients older than 40 years was associated with reliable pain relief and patient satisfaction similar to that after the open Latarjet procedure. Restoration of stability was significantly less successful and development of arthropathy no better than the open Latarjet procedure in patients older than 40 years.

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.

Recurrent Anterior Shoulder Instability

Background: Subgroup analyses of the Latarjet procedure have suggested that age over 40 years is a risk factor for dislocation arthropathy. Purpose: To analyze long-term results of the open Latarjet procedure for recurrent anterior shoulder dislocation in patients at least 40 years of age. Study Design: Case series; Level of evidence, 4. Methods: A total of 39 consecutive patients (40 shoulders) with a mean age of 48 years (range, 40-66 years) at surgery were evaluated at a mean follow-up of 11.0 years (range, 8-16 years). Of these, 15 patients (38%) had undergone previous soft tissue stabilization surgery. Long-term results were assessed clinically and radiographically, including computed tomography scanning at final follow-up. Results: No recurrence of dislocation was noted. Subluxation had occurred in 3 patients (8%), and apprehension persisted in 5 patients (13%). The total Walch-Duplay score averaged 89 points at the final follow-up, and the mean Subjective Shoulder Value (60%-91%) had improved significantly ( P < .001). In total, 36 patients rated their result as excellent, 3 as good. Further, 6 patients (15%) underwent joint-preserving reoperation, and 1 patient (3%) had reverse total shoulder arthroplasty for severe dislocation arthropathy. Dislocation arthropathy was severe in 14 patients (37%) and had progressed by at least 2 grades in 17 patients (45%). Patients with severe dislocation arthropathy had already shown degenerative changes preoperatively as opposed to those who ultimately had no or moderate dislocation arthropathy (n = 24) ( P < .001). Progression of dislocation arthropathy was associated with lateral (>1 mm) graft positioning ( P < .001) and older age at surgery ( r = 0.58; P < .001). Conclusion: The open Latarjet procedure for recurrent anterior shoulder instability in patients older than 40 years reliably restores stability and leads to high patient satisfaction. This procedure is, however, associated with a substantial rate of advanced but clinically mild symptomatic dislocation arthropathy, which is associated with the degree of preoperative joint degeneration, older age at surgery, and lateral graft placement.
