[Renal function after TKR in patients with rheumatoid arthritis who have chronic renal insufficiency].

Twenty three patients with RA who have chronic renal insufficiency were post operatively studied for changes in the renal function with TKR (total knee replacement). We evaluated the renal function by BUN, Creatine, PSP and Creatine clearance. The renal function has not grown worse in all cases. TKR is a safe operation for renal function with careful technique and management.
