Experimental knee simulators have been used to study knee kinematics of total knee replacements (TKR) in cadaver knees. Kinematic results are often reported using a Joint Coordinate System (JCS) introduced by Grood & Suntay in 1983. The JCS relies on bone landmarks in the knee which are removed when a TKR is performed. While it may be expedient to use the closest equivalents of the landmarks from the TKR to build the JCS (rather than the actual anatomic landmarks) doing so may introduce errors that could lead to misinterpretation of the kinematic results. Cadaver studies were performed on two posterior stabilized TKRimplant designs to determine the differences in the kinematic results between using the actual landmarks and their post TKR analogues. The results suggest that substitution of anatomic knee joint landmarks by their closest equivalent TKR landmarks can lead to misinterpretation of femoral roll-back and antero-posterior translation during flexion.
