Incidence of Re-Dislocation/Instability After Arthroscopic Bankart Repair: Analysis via Telephone Interviews

Abstract

Current advances in arthroscopic surgery have led to good outcomes for arthroscopic Bankart repair (ABR) for recurrent anterior shoulder dislocation. However, recent studies have reported recurrence rates of 4%-19% after ABR. In our survey conducted from February 2002 to December 2010, the post-ABR re-dislocation rate was 8.8%. In 2011, we began performing the ABR with open Bristow (B) procedure or Remplissage (R) procedure in patients with large glenoid or humeral head bone defects and in patients who play collision sports. Therefore, the present study is the second series evaluating the incidence of re-dislocation and instability after recurrent anterior shoulder dislocation. Method: Surgery was performed for 84 cases of shoulder instability from January 2011 to August 2017. After excluding 7 open surgeries, 6 reoperations, and 2 patients with multidirectional instability, telephone interviews were conducted with 69 patients. The average follow-up duration was 46.9 months (range, 13-92 months). Result: ABR alone was performed 61 patients; the B procedure was added for 3 patients, and the R procedure was added for 5 patients. Telephone interviews were conducted with 61 patients. There were no cases of re-dislocation or reoperation. Four patients who underwent only ABR experienced postoperative instability, but not to the extent that their daily lives were affected. Conclusion:This study showed that the addition of R or B technique to ABR for recurrent anterior shoulder dislocation resulted in a 0% re-dislocation rate.

“…Follow-up data show good patient satisfaction after surgical repair. The number of patients who suffer from redislocation after arthroscopic Bankart repair has a high variance in current literature and ranges from 0 to 19% [34,35]. Redislocation rates were low in our collective, comparable with the results of Eren et al, who found a redislocation rate of 7.4% five years following arthroscopic Bankart repair [36].…”

Arthroscopic Bankart Repair With Remplissage in Anterior Shoulder Instability Results in Fewer Redislocations Than Bankart Repair Alone at Medium-term Follow-up of a Randomized Controlled Trial

“…However, this methodology (phone interview) has been previously used to capture postoperative recurrence after shoulder stabilization surgery. 2,17 Nevertheless, we could not evaluate the role of objective or subjective apprehension, which may have influenced the outcomes reported. No functional or radiographic assessments were conducted; thus, no comment on the progression of osteoarthritis or other pathologies was possible.…”
