Bilateral replacement of the hip and knee in rheumatoid arthritis.

Twenty-six patients with rheumatoid arthritis who had undergone bilateral replacement of the hip and knee were reviewed at a mean follow-up time of 51.6 months. A further operation was necessary in five patients due to complications of replacement of the knee, and seven patients still had significant pain in at least one replaced joint. There were no cases of infection due to operation. Seventeen of the patients still used walking aids, but one-third of these did so because of pain in joints that had not been replaced. Patients preferred painless total replacement of the hip to that of the knee.
