ObjectiveTo evaluate the short-term effectiveness of arthroscopically capsular vertical mattress suturing for shoulder recurrent anterior dislocation combined with joint laxity.MethodsA retrospective analysis was performed on 6 shoulder recurrent anterior dislocation patients combined with joint laxity treated with arthroscopically capsular vertical mattress suturing between January 2017 and December 2018. There were 5 males and 1 female with an average age of 20.8 years (range, 19-24 years). The number of shoulder dislocation was 3-18 times, with an average of 9.5 times. The disease duration ranged from 2 to 60 months, with an average of 25.3 months. The preoperative Beighton score was 4-7, with an average of 5.8; the Instability Severity Index Score (ISIS) was 2-5, with an average of 3.5. There were 5 cases of simple Bankart injury and 1 case of bony Bankart injury. The range of motion of shoulder joint (including active flexion and lifting, external rotation, abduction and external rotation, and internal ratation) was recorded before operation and at last follow-up; Oxford shoulder instability score, Rowe shoulder instability score, and Simple Shoulder Test (SST) score were used to evaluate shoulder joint function before operation, at 6 months after operation, and at last follow-up, and complications were recorded.ResultsAll patients were followed up 16-28 months (mean, 19.3 months). During the follow-up, all patients had satisfactory motor function, and no re-dislocation and postoperative neurovascular complications occurred. At last follow-up, the activities of active external rotation and abduction and external rotation were significantly improved when compared with those before operation (P<0.05); the activities of active flexion and lifting and internal rotation were not limited before and after operation, and the difference was not significant (P>0.05). The Oxford shoulder instability score, Rowe shoulder instability score, and SST score at 6 months after operation and at last follow-up were significantly improved when compared with those before operation (P<0.05); there was no significant difference between at 6 months after operation and at last follow-up (P>0.05).ConclusionThe treatment of shoulder recurrent anterior dislocation combined with joint laxity by arthroscopically vertical matress suturing can achieve good short-term effectiveness.
