In the human body, a joint is one of the most crucial parts, which always bear the brunt of the aging process. Over a period of time, when the pain leads to an excruciating situation, surgery is the only option available to replace the damaged joint. Joint replacement surgery is removing a damaged joint and putting in a new one. A joint is where two or more bones come together, like the knee, hip, and shoulder. A professional orthopedic does the surgery and he will suggest the treatment and the nature of the surgery to be imparted. Of all the commonly replaced body parts, hips and knees are replaced most often. Other joints that can be replaced include the shoulders, fingers, ankles, and elbows. These can either be cemented or not cemented so that the bones can grow into it. In a Joint Replacement Surgery, the cemented parts are usually performed on older people, as there is no tendency for the bones to grow. However in a relatively younger patient, since the bones grow over a period of time, these are not cemented and they might have to undergo a fresh joint replacement at a later stage in their lives. After the surgery, the Joint Replacement Rehabilitation starts for a patient. This step is very important to make the patient ease back into his daily activities. Thanks to the advancement in modern medicines, these surgeries are relatively painless as their accuracies progresses and these are nowadays performed more commonly on both the old and young alike.
