Acetabular revision for recurrent dislocations: results in 14 cases after 3 years of follow-up.

17 acetabular revisions (16 patients) were performed for recurrent dislocations. 14 patients were examined clinically and radiographically after mean 3 (1-8) years. We found malpositions of components in 12 of 17 cases. 8 of 17 had redislocations and 2 were rerevised. Harris hip scores improved from 57 to 70. 10 of 14 patients were satisfied with the surgical result. Recurrent dislocations have several causes. In our patients, lack of cup anteversion was the commonest indication for revision surgery. We noted a high rate of redislocations and poor clinical results, despite correction of the preoperative component malposition in the 14 cases with follow-up.
