Background:The best treatment of the patella during TKA is controversial. The implantation of a patellar component during a TKA adds to the operation time and the costs of the operation. There is a huge variation around the world as to whether the patella is resurfaced or not during TKA.
Purpose:The aim of this study is to determine whether it is a difference in outcome between patella resurfaced knees and not resurfaced knees at 1 and 3 years after TKA.
Method: Prospective, randomised and double blind study. The primary endpoint is the Knee injury and Osteoarthritis Outcome Score (KOOS).
The secondary endpoints are the Oxford score, Knee Society Score (KSS), stair climbing test with pain scores (VAS) and patient satisfaction (VAS).
