Work disability before and after total hip arthroplasty. Assessment of effectiveness in reducing disability

We evaluated the impact of total hip arthroplasty (THA) on work disability among working age persons. Just over one-third of those totally work disabled prior to THA were working at 1 or at 4 years after surgery. A significant long-term decrease in work disability after surgery was demonstrated by estimating disability prevented by THA, but the decrease was less than suggested by the literature. Preoperative work status and the number of painful joints were significant predictors of return to work.
