All arthroses do not end up in the operating room, thankfully! In fact, only 10% of knee osteoarthritis will require a prosthesis. This is more common for osteoarthritis of the hip. If there is no great revolution in prosthetic surgeries of osteoarthritis, on the other hand the operative techniques are now much more developed.
On the other hand, prostheses are very effective. The operating principle has not changed much in fifty years: we replace the damaged joint with a prosthesis. These are the operative techniques that have evolved. As well as the materials of the prostheses. As a result, these prostheses are better tolerated by the body. They flake much more rarely and are more and more solid. Today, a prosthesis can last 15 to 20 years.
Note that in surgery, cartilage grafts can also be performed. This can only be done for the moment on very limited surface lesions, usually secondary to trauma. In the future, another solution currently in research is the use of stem cells.
> A hip prosthesis is proposed if it is destroyed by osteoarthritis: the joint (femoral head and acetabulum of the pelvic bone) is replaced by a molded metal device. The prosthesis is rarely offered before 60 years. This is a fairly common intervention, with generally few complications.
> In case of severe or aggravating genu varum or genu valgum, the surgeon makes an osteotomy of the tibia, that is to say that he cuts a piece of bone (an angle) to put back the shin in a correct alignment. He will put plates to allow consolidation of the bone. The plates will be removed a few months later.
> The arthrosis of the fingers can also be operated. The rhizarthrosis of the thumb can be very disabling for daily actions, and can be cured by surgery.
