Abstract
We studies 57 knees in 55 patients. 47 knees in 43 had osteoarthritis (OA), and 9 knees in 7 had rheumatoid arthritis (RA). Average age was 71.0 years and the mean follow-up was 3.5 years.On radiological examination, no cases had a “Clear Zone” of over 2mm. Six knees (10.5%) had patella malposition.Using the criteria described by three universities, clinical score was 83.0 points in OA and 80.0 points in RA. These successful results may have been due to preoperative traction, ROM exercise, and exact surgical technique.
