Cadaveric Evaluation of the MAKO Multi Compartmental Knee Kinematics

The MAKO Surgical Rio Robotic Arm utilizes the pre-op CT images to plan positioning of the uni-condylar and patella-femoral components in order to achieve the most desirable kinematics for the knee joint, while preserving the cruciate ligaments. We hypothesize that the anatomic matching surfaces and the cruciate retaining design of the Restoris knee will best replicate normal knee kinematics. It is important to preserve the tracking of the patella for normal knee motion and the preservation of the natural moment arms for mechanical advantage (Li, 2010). We will test the healthy cadaveric knee versus the MAKO knee and the most common TKR designs; Posterior Stabilizing (PS) and Cruiciate Retaining (CR) TKRs in order to evaluate and compare the kinematic properties.
