Knee joint prosthesis articular surface

There is disclosed a knee replacement prosthesis (10) includes a tibial component (10-A) and a femoral component (10-B) with improved articular surface geometries. The improved geometries allow substantial internal rotation of the tibial component (10-A) with respect to the femoral component (10-B)...

Beschreibung
Zusammenfassung:	There is disclosed a knee replacement prosthesis (10) includes a tibial component (10-A) and a femoral component (10-B) with improved articular surface geometries. The improved geometries allow substantial internal rotation of the tibial component (10-A) with respect to the femoral component (10-B) during at least the first twenty degrees (20 DEG ) of flexion. The tibial and femoral components (10-A, 10-B) are capable of flexing about an axis that reaches an inclination of from about ten degrees (10 DEG ) to about fifty degrees (50 DEG ) to the horizontal.
