Femoral component rotation after balanced gap total knee replacement is not a predictor for postoperative patella position

摘要

Purpose Femoral component rotation is believed to be one of the factors influencing patellar tracking behavior. With the balanced gap implantation technique, the rotation of the femoral component can vary as it is guided by the ligaments. This study investigated whether femoral component rotation influenced patella position after primary total knee replacement (TKR).
