Total knee replacement is a rapidly-growing procedure. Initially, knee replacement was intended for patients in their late 60s and 70s. Recent improvements to the prosthesis and overall surgical technique have enabled the procedure to be performed on patients in their 50s as well as their 80s and 90s. Each year, over 600,000 primary total knee replacements are performed in the United States.

Total knee replacement is actually a resurfacing procedure where approximately ½ inch of bone is removed from the lower end of the thigh bone (femur), the upper end of the lower leg bone (tibia), and the under-surface of the knee cap (patella). These surfaces are then covered with a metal prosthesis on the femur and a plastic prosthesis on the tibia and patella.

Total hip replacement is truly a replacement, as opposed to a total knee replacement which is really a resurfacing procedure. In a hip replacement, the femoral head is removed. The cup (acetabulum) is reamed and replaced with a metal-backed plastic cup. A metal stem is placed down the shaft of the thigh bone (femur). A metal ball is placed on top of the stem. The ball is then reduced into the cup. This procedure stops the patient's arthritic femoral head from rubbing against their arthritic cup, relieving their pain.

Hypothesis: Optimal functioning of the prosthesis would involve realistic deformation and motion patterns of the prosthesis during knee joint motion.
