Abstract

The present invention relates to a modular knee prosthesis assembly kit (10) for replacement of resected articular surfaces of a distal femur of a first patient side. The kit (10) comprises (a) at least one bi-condylar component (20) sized and shaped to substantially replace resected posterior and distal condylar bone portions; and (b) at least a first trochlear groove component (50) and a secondtrochlear groove component (70), each sized and shaped to replace a resected trochlear groove bone portion. The first trochlear groove component (50) comprises a first patella articulation path defining a first trochlear groove direction angle. The second trochlear groove component (70) comprises a second patella articulation path defining a second trochlear groove direction angle. An assembly ofthe bi-condylar component (20) and one of the first and second trochlear groove components (50; 70) forms a substantially complete femoral knee prosthesis. The second trochlear groove direction angleis different from the first trochlear groove direction angle.

Description

technical field

[0001] The present invention relates to a fully modular knee prosthesis assembly kit and in particular to a kit useful for obtaining a knee prosthesis with replaceable and individual trochlear groove components. Background technique

[0002] The femur and tibia can cause pain when the cartilage in the human knee wears down due to trauma, wear, or disease. This pain can be caused by parts of the bone in the joint that are not protected by cartilage, or by inflammation of soft tissue structures caused by instability. People with worn-out knees often undergo partial or total knee replacements to restore knee function and eliminate pain.

[0003] The human knee joint consists of the distal femur, proximal tibia, and patella. The distal femur includes medial and lateral condyles that articulate against the tibial plateau and form the tibio-femoral joint. In addition, the distal femur includes a trochlear groove, located between and at least partially above the ...
