We evaluated 71 shoulders of 71 patients (57 males and 14 females) Who had had an open Bankart repair for recurrent anterior instability of the shoulder. Forty patients were operated on using Rowe's modification, 12 with Statak, and 19 with a Mitek G II anchor device. Sixty of the 71 patients had been engaged in athletic or recreational sport activities preoperatively. The postoperative functional results were assessed 0.5-6.9(average, 2.8)years after surgery, using Rowe's rating system and

... gishi's scoring sheet for sporting ability derived from Japan Shoulder Society. Overall, a dislocation recurred in 5 of the 71 shoulders. Rowe's scores ranged from 15 to 100(average, 87) with excellent and good results in 61 patients. No patients who had had a Rowe-modified Bankart operation showed any recurrence of the dislocation. Contrastingly, 4 of the 12 patients operated with Statak had a redislocation, postoperatively, of which 3 showed incomplete insertion of the device into the bone. There was one resubluxation in the patients operated on with a Mitek, although the other 8 were ranked as either excellent or good. The results of Takagishi's scoring indicated that the athletic performance did not change postoperatively, irrespective of the operative procedure, if the patient could return to his sport without fear of a redislocation. We conclude that the proper placement of an anchor device is most important when using it in a Bankart operation, which is also true in an arthroscopic Bankart repair.
