This study investigated the change in joint line position after posterior cruciate–retaining and posterior-stabilized total knee arthroplasty with AMK (DePuy, Warsaw, Ind) and Genesis II (Smith & Nephew, Memphis, Tenn) components. A total of 200 primary total knee arthroplasty patients were randomly selected so as to have 50 patients with each of the 4 prosthesis types. Joint line position was measured on preoperative and 2 year postoperative radiographs by both a lateral and an anteroposterior measurement method. Two-year follow-up functional data were assessed. There were no statistically significant differences in the joint line elevation between posterior-stabilized and posterior cruciate–retaining designs within the same implant system as measured on lateral radiographs. There were no differences in clinical functional outcomes in patients with variable joint line elevation.
