The knee is the largest joint in the body and having healthy knees is required to perform most everyday activities. Nevertheless, it can wear off due to many causes. Some of the most common are Osteoarthritis, Rheumatoid Arthritis, and Post-Traumatic Arthritis; which is why, some people may be candidates for a total knee replacement. More than 90% of patients who have this surgery experience a dramatic reduction of knee pain and a significant improvement in the ability to perform common activities of daily living. Our surgeons will evaluate your case and if you turn out to be a candidate, in this procedure, only the surface of the knee will be replaced following these steps:
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 metal implants. 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.
