Relationship Between Age at Initial Shoulder Instability and Overall Outcomes After Arthroscopic Bankart Repair: Mean 6-Year Follow-up

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: Although Bankart repair with remplissage is commonly performed to treat anterior shoulder instability, there is limited information on specific outcomes or patients’ fears regarding return to sports (RTS). Purpose: To study recurrence rates, pain, shoulder function, active range of motion (ROM), RTS rate, and patients’ fears and expectations for RTS after arthroscopic Bankart repair with remplissage for anterior shoulder instability. We compared these outcomes with those after Bankart repair alone. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective cohort study was carried out between 2007 and 2017 among patients who underwent arthroscopic Bankart repair with remplissage (group BR) and Bankart repair alone (group B). At the final follow-up, outcomes including recurrence, pain, shoulder function, active ROM, RTS rate, and fear toward RTS were assessed. The specific outcomes for RTS were evaluated based on 3 levels: return to normal life, RTS at any level (RTSA), and RTS at previous level (RTSP). Results: A total of 70 patients were included (29 in group BR and 41 in group B) with a mean 67.2 months of follow-up. Group BR demonstrated a significantly lower recurrence rate than did group B (0 vs 22.0%, respectively; P = .007) as well as higher postoperative Rowe score (92.8 ± 7.1 vs 83.3 ± 16.2, respectively; P = .005). There were no differences between the groups in postoperative visual analog scale for pain score, American Shoulder and Elbow Surgeons score, Oxford Shoulder Instability Score, or active ROM. The rates of RTSA (100% vs 84.2%; P = .03) and RTSP (77.8% vs 50.0%; P = .02) were higher in group BR than in group B, respectively, and significantly fewer patients in group BR reported fear of RTS (40.7% vs 63.2%; P = .04). Conclusion: In this study, recurrence rate, pain, shoulder function, active ROM, and RTS rate were satisfactory after arthroscopic Bankart repair with remplissage. Patients who underwent this procedure reported less fear toward RTS and higher rates of RTSA and RTSP than did those who undergo Bankart repair alone.

Background: The objective of the study was to evaluate the functional outcome of arthroscopic Bankart repair for anterior shoulder instability to assess whether the number and position of suture anchors plays a role in determining the functional outcome.Methods: This was a prospective study on 32 patients operated with arthroscopic Bankart repair between December 2017 to April 2019. Pre-op and regular follow-up scores were measured at 1 month, 3 months and 6 months post-op using Rowe score and American Shoulder and Elbow Surgeons score to assess functional outcome.Results: Mean age of the study group was 24.5±6.9 years. Functional outcome as determined by Rowe score and ASES score at 6 months follow-up were found to be 90.5±7.2 and 85.9±14.1 respectively when compared to the pre-op scores of 23.2±8.2 and 47.9±5.7 respectively; all of which showed highly significant functional improvement with highly significant reduction in visual analog scale (VAS) pain score. Patients had no recurrent dislocations with mean external rotation limitation of 5o. 25 (78.1%) patients had two suture anchors inserted and 7 (21.9%) patients had multiple (>2) anchors; and when analysis was done, there was no statistically significant difference between number of suture anchors used with respect to the functional scores.Conclusions: We conclude that arthroscopic Bankart repair is a useful and successful procedure. Patient identification and selection remains the key in determining the success of repair. Meticulous surgical technique and correct positioning of suture anchors may help in reducing the number of anchors without compromising on the final functional outcome, thereby reducing the economic burden on patients.

Background: Arthroscopic Bankart repair (ABR) and the Latarjet procedure are surgical techniques commonly used to treat anterior shoulder instability. There is no consensus among shoulder surgeons regarding the indications for choosing one over the other. Purpose: To compare the results of the Latarjet procedure with those of ABR for the treatment of anterior shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: Data on all patients who were treated surgically for recurrent anterior shoulder instability between 2006 and 2011 were retrospectively collected at 4 medical centers. The minimum follow-up was 5 years. Data were retrieved from medical charts, and patients were interviewed to assess their level of satisfaction (range, 0-100), functional outcomes (using the American Shoulder and Elbow Surgeons shoulder score; the Subjective Shoulder Value; and the Disabilities of the Arm, Shoulder and Hand score), and quality of life (using the 12-Item Short Form Health Survey [SF-12]). Information on return to sports activities and postoperative level of activity compared with that of the preinjury state, complications, reoperations, and recurrent instability were recorded and evaluated. Results: A total of 242 patients were included. The Latarjet procedure was performed in 27 shoulders, and ABR was performed in 215 shoulders. Patients in the ABR group had significantly higher rates of redislocation (18.5%; P = .05) and subluxation (21.4%; P = .43) but a lower rate of self-reported apprehension (43.0%; P = .05) compared with patients in the Latarjet group (3.7%, 14.8%, and 63.0%, respectively). There were 5 patients in the ABR group who underwent reoperation with the Latarjet procedure because of recurrent instability. The functional scores in the Latarjet group were better than those in the ABR group. The SF-12 physical score was significantly better in the Latarjet group than in the ABR group (98.1 vs 93.9, respectively; P = .01). Patient satisfaction and subjective scores were similar in both groups. Conclusion: These results support recently published data on the Latarjet procedure that showed its superiority over ABR in midterm stability (dislocations or subluxations). The contribution of self-reported apprehension to the broad definition of stability is not clear, and apprehension rates were not correlated with satisfaction scores or the recurrence of dislocation or subluxation.

The Mean

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 purpose of this study is to investigate clinical outcomes and radiological findings of cyst formation in the glenoid around suture anchors after arthroscopic Bankart repair with either biocomposite suture anchor or all-suture anchor in traumatic anterior shoulder instability. We hypothesized that there would be no significant difference in clinical and radiological outcomes between the two suture materials.Methods: This retrospective study reviewed 162 patients (69 in group A, biocomposite anchor; 93 in group B, all-suture anchor) who underwent arthroscopic Bankart repair of traumatic recurrent anterior shoulder instability with less than 20% glenoid defect on preoperative en-face view three-dimensional computed tomography. Patient assignment was not randomized. Results: At final follow-up, the mean subjective shoulder value, Rowe score, and University of California, Los Angeles shoulder score improved significantly in both groups. However, there were no significant differences in functional shoulder scores and recurrence rate (6%, 4/69 in group A; 5%, 5/93 in group B) between the two groups. On follow-up magnetic resonance arthrography/computed tomography arthrography, the incidence of peri-anchor cyst formation was 5.7% (4/69) in group A and 3.2% (3/93) in group B, which was not a significant difference. Conclusions: Considering the low incidence of peri-anchor cyst formation in the glenoid after Bankart repair with one of two anchor systems and the lack of association with recurrence instability, biocomposite and all-suture anchors in Bankart repair yield satisfactory outcomes with no significant difference.

Arthroscopic Bankart Repair

Background: Arthroscopic Bankart repair is the most common procedure for anterior shoulder instability management. However, the long-term efficacy of the procedure is questionable, and the results are different among different populations. Few studies have focused on specific populations, such as recreational athletes and laborers. Hypothesis: Good to excellent long-term results, with a low recurrence rate, can be achieved using arthroscopic Bankart repair in recreational athletes and laborers suffering from anterior shoulder instability. Study Design: Case series; Level of evidence, 4. Methods: A specific group of laborers and recreational athletes were included in this study. A total of 52 patients (52 shoulders) with anterior-inferior traumatic shoulder instability underwent arthroscopic Bankart repair and met our strict criteria for study inclusion. The recurrence rate was recorded. Patients were evaluated at a minimum follow-up of 5 years using the American Shoulder and Elbow Surgeons (ASES) score, the Rowe score, the Constant score, and a visual analog scale (VAS) for pain. A radiological evaluation for arthritis was also performed according to the Samilson-Prieto classification. Results: The mean follow-up was 105.4 months (range, 65-164 months). Our overall recurrence rate was 11.5% (6/52 patients). All patients were able to return to their previous job status with minimum limitations, and 76.7% of our study population reported returning to their preinjury sporting activities. Postoperatively, all scores were improved, with statistically significant increases from preoperative values ( P < .001). At the last radiographic follow-up, 9 patients (18.8%) had mild arthritis, while 2 patients (4.2%) had moderate arthritis. Conclusion: Arthroscopic soft tissue Bankart repair may provide good to excellent long-term clinical results with an acceptable recurrence rate in medium-demand patients (recreational athletes and laborers).

Background: In athletes with recurrent shoulder instability, arthroscopic Bankart repair (ABR) and the open Latarjet procedure (OL) are commonly indicated to restore stability and allow them to return to play (RTP). Purpose: To compare the outcomes of ABR and OL in athletes with recurrent shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: We performed a retrospective review of patients with recurrent shoulder instability who underwent ABR and OL and had a minimum 24-month follow-up. Indications for OL over ABR in this population were those considered at high risk for recurrence, including patients with glenohumeral bone loss. The patients were pair-matched in a 1:1 ratio (OL and ABR) by age, sex, sport, and level of preoperative play. We evaluated the rate, level, and timing of RTP, and the Shoulder Instability–Return to Sport after Injury (SIRSI) score between procedures. Additionally we compared the recurrence rate, visual analog scale (VAS) pain score, Subjective Shoulder Value (SSV), Rowe score, satisfaction, and whether patients would undergo the same surgery again. Results: Participants included 62 athletes who underwent ABR and 62 who underwent OL, with a mean follow-up of 47.7 months. There was no significant difference between ABR and OL in rate of RTP, return to preinjury level, time to return, SIRSI score, VAS score, SSV, or patient satisfaction. OL resulted in a significantly lower recurrence rate (1.6% vs 16.1% for ABR; P = .009) and a significantly higher Rowe score (mean ± SD, 90.5 ± 12.2 vs 82.2 ± 20.8 for ABR; P = .008). In collision athletes, there was no significant difference between ABR and OL regarding RTP rate (89.1% vs 94.5%; P = .489) or SIRSI score (70.4 ± 24.8 vs 73.8 ± 19.6; P = .426), but OL resulted in a lower recurrence rate (14.5% vs 1.8%; P = .031). Conclusion: ABR and OL resulted in excellent clinical outcomes, with high rates of RTP in athletes. However, lower recurrence rates were seen with OL.

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. Both percutaneous Achilles tendon lengthening by triple hemisection and the traditional open Z-lengthening are effective methods for Achilles tendon contracture. This study aims to evaluate the efficacy and safety of this new therapeutic method, which is based on the percutaneous sliding technique with three hemi-cuts in the tendon, as compared with the traditional open Z-lengthening. Methods. Retrospective analysis of the Achilles tendon contracture cases in our hospital between January 2010 and September 2016 was conducted. Twenty-five cases received percutaneous Achilles tendon lengthening (group A), and 30 patients who underwent open Z-lengthening during the same period were in the control group (group B). Operative time and hospital stay were statistically analyzed. Incision complication, equinus recurrence rate and Achilles tendon rupture morbidity were recorded. The function was assessed by American Orthopaedic Foot & Ankle Society (AOFAS) score. All cases in group A received Magnetic Resonance Imaging (MRI) of ankle preoperatively and in the follow-ups. Results. The mean follow-up period was 42.04 months in group A and 61.7 months in group B. The entire operative time and the mean hospitalization days were lower in group A than in group B. No incision and infection complication occurred in group A. The infection rate in group B was 3.3%. Equinus recurrence rate was 4% in group A and the equinus recurrence rate in group B was 21.4%. In group A, the mean AOFAS score increased from 64 ± 10.16 points preoperatively to 96.08 ± 3.17 at final follow-up, while the score in group B increased from 63.48 ± 6.2 points to 85.4 ± 10.3. MRI showed continuity of the Achilles tendon and homogeneous signal in group A. Conclusion. Modified surgery can significantly reduce the risk of Achilles tendon rupture, provide better balance in soft tissue strength between ankle dorsiflexion and ankle plantarflexion, helping to avoid recurrence of the deformity.

Background: Although everted bursal flaps of delaminated tears have been reported, few studies have reported radiologic images, arthroscopic findings, and clinical results after repair. Purpose: To compare the repair outcomes of everted delaminated tears with those of classic delaminated supraspinatus tears. Study Design: Cohort study; Level of evidence, 3. Methods: Among 153 patients who underwent arthroscopic rotator cuff repair for a delaminated supraspinatus tear, everted bursal flap tears were observed in 24 patients upon arthroscopy (group A). Another 24 patients with classic delaminated supraspinatus tears, matched for age and sex, were selected for group B. Magnetic resonance imaging (MRI) and ultrasonography were performed preoperatively and postoperatively. Patients were evaluated using a visual analog scale (VAS) for pain as well as functional scores (American Shoulder and Elbow Surgeons [ASES] score, Constant score, and University of California Los Angeles shoulder score). Scores were compared preoperatively and at final follow-up (mean follow-up, 32 months). Results: Patients in both groups A and B reported improved VAS and functional scores at the final follow-up. In group A, preoperative VAS scores were higher and functional scores were poorer than in group B. Subacromial effusions with tendon swelling on preoperative MRI were more common in group A. During follow-up ultrasonography, group A patients exhibited persistent subacromial effusion. However, VAS scores at final follow-up were significantly better in group A (0.4 ± 0.7) than in group B (1.6 ± 1.4) ( P < .001), and ASES scores at final follow-up were better in group A (84.3 ± 4.3) than in group B (77.0 ± 10.2) ( P = .005). Conclusion: Everted bursal flap delaminated tears were associated with higher VAS scores and poorer functional scores preoperatively. Although subacromial effusions were experienced by group A during the early postoperative period, clinical outcomes at final follow-up were significantly better for everted delaminated tears compared with classic delaminated tears.
