ABSTRACT

Objective:To analyze and compare the clinical outcomes of total knee arthroplasty with patella arthroplasty and patella replacement. Methods: From May 1999 to January 2004, 251 knees in 203 patients (45 males and 158 females; age range 25 to 91 years, average 62.8 years) with osteoarthritis (206 knees) and rheumatoid arthritis (45 knees) were evaluated using a questionnaire during physical examination. Totally 137 knees underwent patella arthroplasty and 114 underwent patella replacement, with a mean follow-up of 28.1 months. The patients were scored using KSS Score, Feller Score and British Orthopedics Association Patient-satisfaction Score. Results: Patella arthroplasty and replacement showed no obvious difference in post-operative improvement of the knee score, knee function score, patella function score and range of flexion and extent of knee. Compared with patella replacement group, patella arthroplasty group had a higher patient satisfaction rate (P
