Patient Specific Knee Options
Custom fitted total knee arthroplasty is a newer technology in total knee replacement surgery. It is an advanced procedure using an individualized patient-specific knee implant for replacement of all three components of the knee. The difference with custom knee replacement from other knee replacement surgeries is the use of an MRI scan prior to the surgery that provides a clear view of the shape and structure of the different components of the joint.
The knee joint, made up of the ends of the femur (thigh bone) and tibia (shin bone) is cushioned by a spongy tissue called cartilage. Damage and wear and tear of the cartilage causes painful rubbing of the joint bones, leading to disability. This condition can be successfully treated with knee replacement surgery, which involves the replacement of the damaged tissue with a prosthetic implant.
Knee implants are artificial devices that form the essential parts of the knee during a knee replacement surgery. The knee implants vary by size, shape, and material. Implants are made of biocompatible materials that are accepted by the body without producing any rejection response. Implants can be made of metal alloys, ceramics, or plastics, and can be joined to the bone. The metals used include stainless steel, titanium, and cobalt chrome; whereas, the plastic used is polyethylene.
