WHEN WILL A KNEE PROSTHESIS BE PLACED?
A knee prosthesis (= an artificial knee) is placed in case of severe damage to the knee joint. The cause of this damage is usually osteoarthritis or a rheumatic condition. This causes pain and malfunctions. The damage can be seen on an x-ray of the knee.
WEAR OF THE CARTILAGE IS CALLED OSTEOARTHRITIS
In some people wear is faster. Causes of this are abnormal load, an accident, or shape deviations of the knee joint.
There is certainly also an important family predisposition. Wear is not always due to a specific cause.
Such wear causes pain. When the pain can no longer be remedied by other means, a knee prosthesis will be proposed.
THE KNEE PROSTHESIS
There are two types: the total and half knee prostheses. The most commonly used is the total knee prosthesis, which replaces all the cartilage of the femur and tibia.
The knee operation is no small matter and the recovery requires a lot of will and effort, but through proper preparation you can save unnecessary tensions and disappointments.
THE KNEE OPERATION
During the procedure, you will receive antibiotics to reduce the risk of infection. The surgery takes about 1.5 hours. During the knee operation the knee is opened at the front by a vertical cut of about twenty cm. The surgeon removes the affected joint surfaces. With special instruments the bone is adapted to the shape of the prosthesis, so that a good anchoring is possible. A plastic disc between the metal parts of the prosthesis ensures that the knee can pivot smoothly. Generally no kneecap prosthesis is placed, because special treatment of the own kneecap ensures that hardly any complaints of the kneecap remain. Experience from America has shown that arthritic disks have a complication risk in the short and long term to about 10%! Therefore, a kneecap prosthesis is only placed on indication. These indications are: (serious) rheumatism or severe knee-caries.
