Ask a question


The knee is the most common location of osteoarthritis. Osteoarthritis is the wearing down of the joint, by degeneration of the articular cartilage with age. Osteoarthritis of the knee is favored by obesity and can localize in the joint between the femur and the tibia, but also between the femur and the patella (kneecap). The main symptom of osteoarthritis is pain during movements involving the knee, then comes stiffness, with difficulty mobilizing the joint, and the deformity of the knee in advanced stages. Osteoarthritis is detected with an X-ray of the knee. The treatment is mainly for pain with painkillers or anti-inflammatories. Injections are also possible and, as a last resort, a prosthesis can replace the affected joint.
