¿, which consists in the implantation of prosthetic knee

?

In this procedure the damaged parts of the knee joint are removed and some components called implants replaced. These implants are made ​​of a material compatible with our tissues, such as polyethylene or titanium. Models exist fixing prostheses to bone with the help of a special acrylic cement. Other cementless prostheses are placed and require adjustment or bone perfect fit.

Usually implants knee prosthesis are bonded to or in a weaker bone in the elderly, and placed in uncemented bones more resistant and Young. Uncemented components have a rough surface with small pores and in which bone grows. So that the prosthesis becomes bound to the strongest possible, that is, in a biological way, integrating the bone surface.

¿, in which situations it is advisable to carry out the operation

?

This indicated the placement of a prosthetic knee joint is painful when advanced wear and often have already tried other treatments without success.

¿kind of post-operative recovery is done ?¿How long does

?

In the Postoperative immediately do exercises to regain mobility of the knee and strengthen the muscles of the limb. This exercise program is continued performing at home. In addition patients are trained to march, usually with partial load and crutches for a period which may vary according to the condition of the bone, age and type of prosthesis.

¿Osteoarthritis is one of the most common causes for the insertion of a new prosthesis

The osteoarthritis is the most common joint disease and also the most common cause of musculoskeletal disability. It is characterized by a wear layer of cartilage that lines the joints, forming in its place bone tissue.

Factors that predispose to osteoarthritis is family history, poor alignment of the legs, obesity and jobs that involve continuous loads or impact on the joints, particularly working long hours standing or involve heavy lifting.

Once the patient is fully recovered. & iquest;What physical activities can not be done ?¿What actions require some care when performed by

?

The wearer of a knee prosthesis can lead a practically normal life without limitations for the march. However, it should reduce activities that involve impact, such as running and jumping.

With the passage of time,¿, may cause problems or can wear

?

Materials implanted prostheses have a limited life, which varies from one person to another. With current models has greatly lengthened its duration, between 10 and 15 years. When a prosthesis begins to fail, its components are loosened. Their mobility causes discomfort and decaying bone, thereby causing the replacement of the implants.
