Abstract
Knee prostheses are provided. In some embodiments, the knee prostheses include a body formed of a resilient polyurethane having contact surface area that changes during use according to physical loading factors. In some embodiments, the knee prostheses include a femoral component configured for secure engagement with a lower portion of a femur without penetrating the femur and a tibial component configured for secure engagement with an upper portion of a tibia without penetrating the tibia. In that regard, the tibial component is also configured for moving engagement with the femoral component in some instances.
