TOTAL KNEE REPLACEMENT

ABOUT MY SURGERY

A knee replacement (also called knee arthroplasty) might be more accurately termed a knee “resurfacing” because only the surface of the bones are actually replaced. There are four basic steps to a knee replacement procedure:


Prepare the bone.

The damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of underlying bone.

Position. The removed cartilage and bone is replaced with metal components that recreate the surface of the joint. These metal parts may be cemented or “press-fit” into the bone.


Resurface the patella. The undersurface of the patella (kneecap) is cut and resurfaced with a plastic button. Some surgeons do not resurface the patella, depending upon the case.


Insert a spacer. A medical-grade plastic spacer is inserted between the metal components to create a smooth gliding surface.
