Hypothesis: We hypothesized that the arthroscopic Bankart repair (ABR) in patients with anterior instability of the shoulder would result in favorable, compared with the previous studies.
Methods: Ninety-five patients with anterior instability were candidates for this study: 74 males and 21 females. Those who had concomitant rotator cuff tears were excluded from this study. The average follow-up period was 47months (range: 12-110 mos). The average age of the patients at the time of surgery was 26.9 years old (range: 14-72) and the average age at the initial dislocation/subluxation was 20.5 years old (range: 12-60). Thirty-one patients had experienced the dislocation/ subluxation less than 5 times before the operation, 20 patients between 5 and 10 times, and 44patients more than 10 times. Either PanaLok or PanaLok Loop anchor (Mitek) was used during operation (3-5 anchors/ patient). The shoulder was immobilized in a brace for 3 weeks after the surgery. Passive elevation of the shoulder was commenced at 3 weeks after surgery, and active motion of the shoulder was allowed at postoperative 6 weeks. Japanese Shoulder Society Shoulder Instability Score (JSS-SSI) were measured preoperatively and postoperatively. Wilcoxon rank test was used as statistical analysis. P value less than 0.05 was considered significant.
Results: The average points of JSS-SIS were improved from 63.3 points preoperatively (range: 39-87) to 96.1 points preoperatively (range: 93-100) postoperatively. Postoperative re-dislocation was noted in 5 patients (5.2%).
Conclusion: Our ABR managed to produce good results in patients with anterior instability of the shoulder.
