Results of a single total knee prosthesis compared with multiple joint replacement in the lower limb.

We present the clinical results of total knee replacement (TKR) in 133 patients who had two or more major joints of the lower limbs replaced, and compare them to the outcome in 406 patients with an isolated TKR. 383 patients had osteoarthritis (OA) and 136 had rheumatoid arthritis (RA) and these were assessed separately. A meniscal bearing prosthesis was used. The functional score was high and there was no statistically significant difference in the incidence of complications between the two groups.
