Function after revision of failed total hip arthroplasty

Measurements of functional performance were made before and 6 months after 31 primary total hip replacements and 31 total hip revisions for prosthetic loosening. After revision, functional performance returned to levels substantially the same as after primary hip replacement except for greater reliance on canes for patients in the revised group. Ratings of hip status and hip pain were slightly less satisfactory after revision as compared to after the primary operation.
