What is total knee replacement?

Also called arthroplasty, total joint replacement is a surgical procedure in which both sides of a joint are removed and replaced by artificial implants (prostheses) that are anchored to the bones.

A total knee replacement is really a bone and cartilage replacement with an artificial surface. The knee itself is not replaced as commonly thought, but rather an implant is inserted on the bone ends. This is done with a metal alloy in the femur (thigh bone) and plastic spacer on the tibia (lower leg bone) and patella (knee cap). This creates a new, smooth cushion and functioning joint that can reduce or eliminate pain.

The knee itself is not replaced, as is commonly thought, but rather an artificial substitute for the cartilage is inserted on the end of the bones. This is done with a metal alloy on the femur and plastic spacer on the tibia and kneecap (patella). This creates a new smooth cushion and a functioning joint that does not hurt.
