Abstract
A knee prosthesis which more accurately reproduces the rollback of natural knee movement and, thus, reduces wear on the tibial component. The knee prosthesis includes a femoral component with two cams, the first located between the posterior condylar sections and the second located towards the anterior end of the condylar sections with a slot surface therebetween. The tibial component includes a spine which engages each cam as it rotates along the femoral component and the slot surface during flexion and extension.
