Failure of reinserted short external rotator muscles after total hip arthroplasty

The frequency and point in time of failure of repaired short external rotator muscles were determined in 27 total hip arthroplasties. The piriformis, triceps coxae, and obturator externus muscles were released close to the trochanter and reattached only if tension was low and if the tendon tissue allowed a good hold for anchoring the stitch.
