Purpose of the study

To compare the patellofemoral kinematics and patella stability of a new TKR, with a continuous radius versus an established J shaped knee system and the natural knee. It was hypothesised that the high performance new TKR would be a better match to the natural knee and anatomical patella tracking would provide a more stable patella.

Methods

A cadaveric study using physiological loads examined the continuous kinematic behaviour (optical tracking system) of the tibiofemoral and patellofemoral compartments in 6 knees for the native, kinemax and new design triathlon knee systems.
