In vivo sagittal plane kinematics of the Avon patellofemoral arthroplasty.
Isolated patellofemoral osteoarthritis can be treated with patellofemoral arthroplasty (PFA). In contrast to total knee arthroplasty, the effect of PFA on knee joint kinematics is not known. A study was performed to identify the kinematic changes after PFA. The sagittal plane kinematics was examined in 12 patients who had undergone Avon PFA. An established fluoroscopic method was used to examine the patellar tendon angle (PTA)/knee flexion relationship during functional activities. No signifi...Expand abstract
