Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective of the study is to evaluate if patients undergoing resurfacing of the patella during TKA show at least 10 % improvement in the Baldini score (after 18 months) compared to patients undergoing TKA without resurfacing of the patella. Hypothesis: Patella resurfacing in patients with symptomatic knee OA who are indicated for total knee replacement and show clinically and radiologically signs of patellofemoral OA will give an improvement of the Baldini score > 10% (after TKA) compared to patients without resurfacing the patella. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcomes of the study are to: 1. Evaluate the Knee Injury and Osteoarthritis Outcome score (KOOS); 2. Evaluate the correlation between the Knee Injury and Osteoarthritis Outcome score (KOOS) and the patellofemoral scoring system by Baldini with regard to patellofemoral symptoms; 3. Evaluate the correlation between the Knee Society clinical rating system (KSS) and the patellofemoral scoring system by Baldini with regard to patellofemoral symptoms. | — |
