What Is Total Knee Replacement?
Total knee replacement is an orthopedic surgery where your diseased knee is removed and replaced with an artificial joint. The lower end of your femur (thighbone) and the upper end of your tibia (your leg bone) meet behind the patella (knee cap).
Surgeons repair any damaged surfaces and replace the hinged area of the knee with an artificial joint, called a prosthesis. A surgeon removes the lower end of the femur and the upper end of the tibia. The prosthesis is connected to both large bones. Depending on the condition of the patient's knee, the posterior cruciate ligament (which holds the leg in alignment) may be also be replaced.
