Method and apparatus for replacing knee-joint

The present invention includes a method of performing knee-joint replacement surgery. The tibia and the femur are positioned such that the knee-joint is disposed in a bent position. An incision is made over or adjacent the patella to expose the knee-joint. A retractor support is extended along at least opposite sides of the knee-joint. The skin flesh layers proximate the knee-joint are retracted utilizing a plurality of retractors which are attached to the retractor support. At least one of the retractors is attached to the retractor such that the retractor may be flexed sufficiently for movement of the knee-joint during surgery without having to reposition the retractors.
