Fascia lata plasty in recurrent posterior dislocation after total hip arthroplasty.

With a soft-tissue plasty, stability could be obtained in 17 of 22 patients with unstable hips after total hip arthroplasty. While in 16 of 18 patients with a posterior instability stability was achieved, only 1 of 3 patients with a unstable hip for dislocation in all directions was successfully treated. No stability could be achieved in one patient with a hip which dislocated anteriorly. The method described should only be used for posterior recurrent dislocations after total hip arthroplasty.
