Abstract

The goal of this study was to determine the kinematics of cadaveric knees previously implanted with a total knee arthroplasty (TKA)prosthesis during a simulated lunge activitiy. A closed chain knee testing machine was used to simulate a single leg lunge while a commerical surgical navigation system was used to track the motion of the femur and tibia. Four specimens with previously implanted TKAprostheses of different designs were tested through flexion/extension.After testing, the implant components were retrieved and reverse-engineered, and custom Matlab code was used with the CAS output and the three-dimensional implant models to output kinematic behavior of the cadaver knees similar to post-operative surveillance testing. Comparisons to published literature indicate that the CAS system successfully reported TKAkinematics, demonstrating the utility of the CAS system when coupled with a known implant model.
