Knee Replacement Canadian Testimonial

http://orthopedicsportsinstitute.com Trent shares his success story of traveling to the United States for his Knee Replacement Surgery. Dr. Jeffrey Lyman, M.D. performed surgery on Trent in Coeur d'Alene, Idaho. With age and also with rheumatoid arthritis the weight bearing surfaces of the knee joint become worn away. They are no longer smooth and free running and this leads to stiffness and pain. Eventually the joint wears away to such an extent that the bone of the femur grinds on the bone of the tibia. A total knee replacement replaces these surfaces with plastic and metal. The femoral replacement is a smooth metal component, which fits snugly over the end of the bone. The tibial replacement is in two parts, a metal base sitting on the bone and a plastic insert, which sits between the metal base on the tibial and femoral component. If necessary the patellar surface (under the knee cap) is replaced with a plastic button, which glides over the metal surface of the femoral replacement. To be able to replace the surface of the knee joint a 20cm incision is made down the front of the knee and the joint opened. The bony overgrowth, which commonly occurs in arthritis of the knee, is trimmed away and the joint surfaces removed. This involves some shaping of the bone so that the joint replacement components sit firmly on the bone. In the replacements now being used the bone then grows into the roughened surfaces of the replacement, anchoring it down. In addition, bone cement is used to hold the components in place.
