Normal Anatomy of the Knee Joint
Surgery is indicated when non-operative measures no longer control the pain and your quality of life is significantly affected. Over 85% of knee replacements will achieve a good pain free functional result however there are some patients (around 5%) that may still have a niggling ache in the replaced knee joint.
Total knee replacement is actually a resurfacing procedure where approximately ½ inch of bone is removed from the lower end of the thigh bone (femur), the upper end of the lower leg bone (tibia), and the under-surface of the knee cap (patella). These surfaces are then covered with a metal prosthesis on the femur and a plastic prosthesis on the tibia and patella.

Total knee replacement is a rapidly-growing procedure. Initially, knee replacement was intended for patients in their late 60s and 70s. Recent improvements to the prosthesis and overall surgical technique have enabled the procedure to be performed on patients in their 50s as well as their 80s and 90s. Each year, over 600,000 primary total knee replacements are performed in the United States.
Total hip replacement is truly a replacement, as opposed to a total knee replacement which is really a resurfacing procedure. In a hip replacement, the femoral head is removed. The cup (acetabulum) is reamed and replaced with a metal-backed plastic cup. A metal stem is placed down the shaft of the thigh bone (femur). A metal ball is placed on top of the stem. The ball is then reduced into the cup. This procedure stops the patient's arthritic femoral head from rubbing against their arthritic cup, relieving their pain.
The Facts About Total Knee Replacement Surgery - …
Fortunately, before even considering knee replacement surgery as an option, generally physicians will try to find other ways of assuaging the pain. For instance, physical therapy, analgesics and walking aids might be the answer to many knee problems including those stemming from arthritis.
However, it is also nice to know that when other treatments prove to be futile, knee replacement surgery is an option. So prevalent is this surgery, in fact, that over 250,000 knee surgeries are performed each year in the United States alone. It is estimated that in 2040, more than 500,000 knee and hip replacement surgeries will be performed due to the influx in aging Baby Boomers. Knee replacement will help renew the ability to participate in several fun, day to day activities such as gardening, going on walks, golfing, and overall mobility. It is important to try other options before knee replacement surgery, however, since they only last for 15 to 20 years and are not easily replaced. For this reason, physicians are very selective about the types of candidates for the surgery.

Knee replacement is a procedure generally reserved for those who are over 60 years of age who are in relatively good health, aside obviously, from their knee pain.

To receive knee replacement surgery, you must be a good candidate. If not, surgery could prove counterproductive. For some, knee replacement surgery is not in their best interest. Those who are too young, with the exception of those who suffer from severe rheumatoid arthritis, should consider other types of treatment for knee pain since after 15 or 20 years, the prosthesis will need to be replaced. Unfortunately, the bone will need to be cut short to make room for a new prosthesis and function and mobility is likely to be damaged during the second operation. Those who are overweight are not good candidates as the prosthesis (just as the natural knee) is designed to carry a weight in proportion to the person’s body. Too much weight on the prosthesis can cause it to be damaged and subsequent knee surgeries will be necessary. Those with cardiovascular problems and with terminal illnesses are also not good candidates as the surgery may be too much for the body to handle. Also those with poor skin coverage over the knee are not good candidates as surgery could impair movement of the knee.

During knee replacement surgery, you will be under general anesthesia meaning you will be asleep and without pain during the entire procedure, which usually lasts a few hours. The knee is opened up and the kneecap is moved out of the way. Doctors then, shave off the bottom of the femur and the top of the tibia and fibula bones. The prosthesis is then glued to the bones with special, surgical cement. The knee is then sutured back together and drainage tubes are used to prevent clogging.
