Abstract:
Objective To compare retrospectively the clinical outcome of total knee replacement with and without patellar replacement. Methods From January 1994 to December 2000, 109 knees in 86 patients treated for osteoarthritis and rheumatoid arthritis were evaluated postoperatively using a questionnaire and physical examination. There were 17 males and 69 females with the age ranging from 37 to 80 years (average 65.7 years). The osteoarthritis was 8 knees and rheumatoid arthritis 69 knees. Forty-two knees underwent patellar replacement, and 67 knees with reserved patella. The patients were scored using HSS Score for knees and Feller Score for patella. AP and lateral views of the knee as well as 30? and 90? axial views of the patella were taken in radiography .The data were analyzed using SPSS software. Results Replacement and non-replacement groups showed no obvious difference in post-operative knee function and the incidence of complication. The two groups showed statistical significant differences in scoring on climbing and descending stairs and rising from sitting position, the results suggested the replacement group scored slightly better than the nonreplacement group. Post-operative anterior knee pain occurred more commonly in the non-replacement group and showed significant difference (P
