Abstract:
Objective:To explore the short-term effect of arthroscopic posterior suture of the glenoid labial capsule in the treatment of recurrent posterior subluxation (RPS) of shoulder joint.Methods:A retrospective study was conducted on 16 RPS patients who had undergone arthroscopic posterior glenoid capsule folding suture from January 2016 to December 2018, including 12 males and 4 females, with an average age of 22 years (range, 18-37 years). 11 had full-thickness posterior glenoid tear (2 with SLAP injury, 7 with posterior capsular laxity), and 5 had partial posterior glenoid tear (5 with posterior capsular laxity). All 16 patients had active shoulder pain and had undergone arthroscopic posterior glenoid capsule folding suture with suture anchors. After surgery, shoulder abduction was fixed with a sling for 6 weeks to prevent internal rotation of the shoulder; full range of active and passive activities were performed 2-3 months after surgery, and normal movement was resumed 6 months after surgery. Shoulder function was assessed using the American Society of Shoulder and Elbow Surgery (ASES) score and the University of California at Los Angeles (UCLA) end-result score, and shoulder stability was assessed using the instability score in the ASES score.Results:All 16 patients were followed up for 19 months (range, 12-36 months). The shoulder instability score was reduced from 7.6±1.6 preoperatively to 2.0±1.2 postoperatively ( t=5.562, P< 0.001); the ASES score was improved from 45.9±9.8 preoperatively to 85.8±6.1 ( t=39.937, P< 0.001); the pain score was increased from 18.9±5.4 preoperatively to 40.9±4.2 ( t=22.063, P< 0.001); the daily life score was improved from 27.0±7.8 preoperatively to 44.9±3.4 ( t=17.875, P< 0.001), and the UCLA score was improved from 16.1±4.5 preoperatively to 31.9±2.6 ( t=15.813, P< 0.001). One patient had pain during boxing 12 months after surgery, and all patients had significant improvement in shoulder weakness and instability. No patient had instability recurrence. Magnetic resonance showed sutured posterior labrum tearhealed. Conclusion:Arthroscopic posterior glenoid capsule folding suture can repair the labrum injury and restore the tension of the posterior capsule. The glenoid capsule complex healed can increase the posterior obstruction of the scapula. This method can effectively treat RPS with good short-term efficacy.
