Abstract:Objective?To assess the effectiveness of Bankart repair under arthroscope in treatment of recurrent anterior shoulder joint instability.?Methods?From February 2010 to February 2015, 63 patients with recurrent anterior shoulder dislocation under arthroscipic Bankart repair, and 53 patients (28 male, 25 female) were available for follow-up. The mean age at the time of surgery was 27.9 years (range, 16 ~ 51). All of the 63 patients underwent surgical treatments, and the effectiveness was evaluated with University of California at Los Angeles (UCLA), American Shoulder and Elbow Surgeon scores (ASES), Constant-Murley scores, forward elevation, abduction and external rotation and X-ray.?Results?The ASES scores, UCLA scores were (97.0 ± 6.8), (29.6 ± 2.5) respectively, improved significantly higher after the surgery (P < 0.05). No significant change was found regarding Constant-Murley scores (99.1 ± 2.4), forward elevation (168.7 ± 2.7)°, abduction and external rotation (72.6 ± 8.7)° compared with the pre-operation.?Conclusions?Significant difference between pre-operation and post-operation suggests that Arthroscopic Bankart repair is a good option for the treatment of recurrent anterior shoulder dislocation without large glenoid bone loss and poor quality Ligament and joint capsule. Risk factors of recurrence should be evaluated before the surgery to reduce the recurrence rate of dislocation.
