Title: (EN) Systems and methods for providing deeper knee flexion capabilities for knee prosthesis patients
Abstract: front page image
(EN) Systems and methods for providing deeper knee flexion capabilities, more physiologic load bearing and improved patellar tracking for knee prosthesis patients. Such systems and methods include (i) adding more articular surface to the antero-proximal posterior condyles of a femoral component, including methods to achieve that result, (ii) modifications to the internal geometry of the femoral component and the associated femoral bone cuts with methods of implantation, (iii) asymmetrical tibial components that have an unique articular surface that allows for deeper knee flexion than has previously been available and (iv) asymmetrical femoral condyles that result in more physiologic loading of the joint and improved patellar tracking.
