[Arthroscopic capsulo-labral repair and refixation with Mitek anchor in anterior shoulder instability].

From May 1992 to September 1995, 38 patients with recurrent anterior shoulder instability underwent arthroscopic stabilization. The arthroscopic stabilization was performed by capsular shifting and labral refixation using Mitek anchors, based on the Wolf procedure. Immediately after operation active assisted shoulder mobilization was initiated (elevation 60 degrees, external rotation 20 degrees less than contralateral shoulder). After a mean follow-up of 24 months (12-42 months) 30 patients were evaluated by means of the Rowe Score. Excellent and good results were achieved in 90% (n = 27) of patients and 80% had no restriction in sports activities. In 4 of the patients (13%) redislocation occurred. Analysis of the recurrence revealed no adequate trauma in two patients with preoperative multidirectional laxity. One had a trauma and the fourth showed no compliance in the early postoperative period. Compared to the open Bankart operation the described procedure shows a slightly higher rate of redislocations. However, the approach is less invasive and the subscapularis tendon with its proprioception remains intact.
