Abnormal patellar tracking is one of the major causes of anterior knee pain and revision surgery after total knee arthroplasty (TKA)1. Patellar tracking after TKA results from several factors including component design, tissue balancing during TKA, shifting of the joint line, and alignment of the patellar and femoral prosthetic components, all of which can lead to anterior knee pain2. The purpose of this study was to observe in vitro the relationship between altered patellar tracking after TKA during a simulated squat activity and the alignment of the patellar component during TKA.
