We have performed the arthroscopical Bankart repair for recurrent anterior shoulder dislocation. Rehabilitation after surgery was performed as outpatient or as inpatient. The purpose of this study was to evaluate the clinical results of arthroscopical Bankart repair correlation of the period of hospitalization. We treated 24 recurrent anterior shoulder dislocation by arthroscopical Bankart repair in 2004. The outpatient group was 13 cases and the inpatient group was 11 cases. Sex, the averaged age at operation, the mean follow up period were not significant in the 2 groups. The clinical evaluation was performed using the JSS Shoulder Instability Score. The range of motion and muscle strength were evaluated by Cybex. The average postoperative JSS Shoulder Instability Score was 92.4 points in the outpatient group and 93.4 points in the inpatient group. There was no significant correlation between the postoperative range of motion and muscle strength in flexion, internal rotation and the period in hospital. The range of motion in external rotation at 2 months after surgery and muscle strength in external rotation at 6 months after surgery in the inpatient group was higher than in the outpatient group. The clinical results of recurrent anterior shoulder dislocation correlated the period in hospital as to the range of motion and muscle strength in external rotation at an early stage after surgery.
