High Tibial Osteotomy is most effective for active patients who are 40 to 60 years old. Good candidates have pain on only one side of the knee and no pain under the kneecap. Knee pain should be brought on mostly by activity, as well as standing for a long period of time.
Joint replacement aims to restore painless motion to a joint and function to the muscles, ligaments, and other soft tissues that control the joint. Either a part or the total damaged bone is removed and replaced with artificial components made out of metal and polyethylene and the bones of the joint are "realigned" so that the weight that passes through the joint is normally distributed. Hip and knee the major weight bearing joints are the most commonly affected joints and are commonly replaced. Ankles, shoulders, elbows, wrists and fingers can also be replaced.
Joint replacement relieves pain, restores function and the newer type of joints allows unrestricted activities.
Previously it was recommended for patients more than 60 years but now it is being more and more recommended for younger patients.
