Anterior stabilized knee implant

Abstract

A posterior cruciate ligament retaining knee implant prosthesis comprising a femoral component including a medial condyle and a lateral condyle separated from one another by an intercondylar channel adapted to accommodate throughput of a native cruciate ligament, both the medial condyle and the lateral condyle posteriorly terminate individually, the medial condyle including a medial condyle bearing surface and the lateral condyle including a lateral condyle bearing surface, the femoral component including an anterior cam, and a tibial component including a medial condyle receiver having a medial condyle receiver bearing surface, the tibial component also including a lateral condyle receiver having a lateral condyle receiver bearing surface, the tibial component also including an anterior post.

Description

technical field

[0001] The present disclosure relates to orthopedic knee prostheses, and more particularly, to anteriorly stabilized orthopedic knee prostheses for posterior cruciate-preserving total knee arthroplasty. Background technique

[0002] The knee is the largest joint in the human body. Performing most daily activities requires normal knee function. The knee joint is made up of the lower end of the femur, which rotates over the upper end of the tibia, and the patella, which slides in a groove on the end of the femur. The greater ligaments connect to the femur and tibia to provide stability. The long thigh muscles give strength to the knee joint.

[0003] The joint surfaces where these three bones meet are covered with articular cartilage, a smooth substance that cushions the bones and allows them to move easily. The condition of this cartilage-filled knee joint is a key aspect of normal knee function and is critical to the physician's assessment of the need for...
