Knee Replacement
Total knee replacement involves removing the worn-out joint surfaces and implanting prosthetic device in place of the damaged surfaces. Only 8 -10 mm of the damaged bone surface is removed. The shape of the implants (prosthesis) closely matches the amount of bone removed. The femoral component is made of metal and has a bi-condylar shape. The tibial component consists of an oval shaped metal tray with a highly cross-linked polyethylene inset. The patellar component is a circular polyethylene disc with convex surface. Resurfacing of the knee cap is optional. The implants are fixed using acrylic bone cement.
