Cost of Total Knee Replacement

Knee joint failure caused by osteoarthritis. There are many different causes of knee pain, including injury, arthritis and infection. Knee replacement and arthroplasty , is a commonly operation of the knee. Total knee replacement is an elective operation. This operation is undertaken by orthopaedic surgeons and consists of replacing the diseased and painful joint surfaces of the knee with metal and plastic components shaped to allow continued motion of the knee. In total knee replacement surgery, the parts of the bones that rub together are resurfaced with metal and plastic implants.

Using special, precision instruments. Replacement surfaces will then be fixed into place. The surface of the femur is replaced with a rounded metal component that comes very close to matching the curve of your natural bone. The surface of the tibia is replaced with a smooth plastic component. This flat metal component holds a smooth plastic piece made of ultra-high-molecular-weight polyethylene plastic that serves as the cartilage. The undersurface of the kneecap may also be replaced with an implant made of the same polyethylene plastic. It is usually undertaken when knee problems associated with osteoarthritis, and rheumatoid arthritis have resulted in the wearing down of the knee joint. Total knee replacement operation, a surgeon cuts away damaged bone and cartilage from your thighbone, shinbone and kneecap, and replaces it with an artificial knee joint (knee prosthesis) made of metal alloys, plastics and polymers. Total knee replacement surgery should improve an individual's mobility, by reducing pain and improving the function of the knee joint.

Today, total knee replacement has become a common and predictable procedure. Many patients enjoy relief from pain and improved function, compared to their status before surgery. There are many different implant manufacturers and all require slightly different instrumentation and technique. The first surgery a patient goes through for a knee replacement is called a primary surgery; any subsequent surgeries (usually to fix or replace the first implant) are called revisions. The standard technique involves exposure of the front of the knee by a long incision. Techniques of Minimally Invasive Surgery are being developed in Total Knee Replacement but have not yet found complete acceptance. Total knee procedure includes four major implant components and the total implant price ranges from $4000 to $6500 (USD). Knee replacement is a routine surgery performed on over 600,000 people worldwide each year. Over 90% of people who have had Total Knee Replacement experience an improvement in knee pain and function. In a country like the UK where total knee replacement is free of charge on the NHS (National Health System). It is easy to underestimate the cost of such a procedure. In the U.S., the average joint replacement patient is around 65-70 years old, however patients of all ages have received knee implants.
