An artificial knee joint is used in severe knee osteoarthritis and is concerned for the patients are the only way to get rid of his severe pain. Common knee replacements have an average lifespan of fifteen years. Be used after this time usually has a new prosthesis. New technologies allow for a surgical procedure with which the regrowth of the damaged cartilage cells is stimulated by the osteoarthritis of the knee. This is done within three months after surgery. In this bioprostheses surgery the procedure is gentler than in the establishment of a conventional artificial knee joint. This will be done minimally, that is, with a particularly tissue-sparing procedure in which the joint will not be exposed. The patient receives a general anesthetic. With an RF cutter is first removed a thin layer of bone within the joint to bleed until the underlying layer to begin. This abrasion-called method of self-healing process is put in motionbecause the bones contain the leaking blood adult stem cells, which are changing within the next three months to cartilage cells. The Expert Opinions on the question of how robust the new cartilage layer is separated. Some say she is just as good as the original layer of healthy, they said, the bioprosthesis could take over the duties of the original cartilage tissue only partially, but not replace it completely, so the use of an artificial knee joint but must still take place later. Lanzeit-test showed, however, believes that the bioprosthesis in most cases, at least as long as a knee prosthesis and the better for a motion of the knee. Moreover, such a knee replacement surgery can be performed repeatedly. With appropriate exercise therapy, the knee may be well again moved, even sporty, the patient can operate again.
