Abstract:

BACKGROUND: Controversy remains as to whether or not to resurface the patella in total knee replacement.
OBJECTIVE: To investigate the clinical and radiological results of the patella in patients with total knee replacement without patellar resurfacing.
METHODS: Thirty-nine patients (48 knees) with osteoarthritis and rheumatoid arthritis underwent total knee replacement without patellar resurfacing.
RESULTS AND CONCLUSION: Thirty-six knees (75%) were evaluated as grades Ⅲ and Ⅳ of cartilage Outerbridge classification. HSS score and Feller patella score improved postoperatively. Five of the 48 knee (10%) complained of anterior knee pain, and the patella pathological level reached grade Ⅳ. Selective total knee replacement without patellar resurfacing can lead to reduction of patellofemoral complications and acquire good patellofemoral tracking.
