A Total Knee Replacement is a medical procedure whereby the ailing knee joint is replaced with artificial surface. The knee is a hinge joint which delivers gesture at the point where the thigh meets the lower leg. The thighbone (or femur) abuts the big bone of the lower leg (tibia) at the knee joint. During a total knee replacement, the cartilage of both tibia and femur are resurfaced with metal prosthesis and the menisci are replaced with plastic component. Depending on the disorder of the kneecap portion of the knee joint, an artificial “button” may also be additional under the kneecap surface. The artificial mechanisms of a total knee replacement are denoted to as the prosthesis.
