Knee Replacement is one of the most successful and common surgeries done all over the world for knee arthritis. With age, the cartilage which covers the rubbing surface of bones in joints wears out leading to pain, swelling and stiffness of the knee joint called knee arthritis. Due to ageing and continuous wear and tear the sensitive nerve ends are exposed causing severe pain. With time the complete loss of cartilage occurs leading to severe pain, stiffness, and deformity. Best Knee replacement surgery can be Partial/Unicompartmental knee replacement or Total knee replacement depending upon the stage of arthritis at which the patient undergoes surgery.
