Abstract
The senior author altered his surgical technique during total hip
arthroplasty from capsulectomy and capsulotomy with closure of the
external rotator muscles to capsulotomy and capsulorrhaphy. One
thousand patients (500 treated with each procedure) were studied
retrospectively in order to determine the prevalences of dislocation
after surgery with the two different techniques. The prevalence
of dislocation was 2.8% after the capsulectomy and capsulotomy,
whereas it was 0.6% after the new technique; this was a
significant decrease in the rate of dislocation (p < 0.005,  = 0.10).
