Orthopedics is the medical specialty of treatment of the musculoskeletal system.Orthopaedics is the process that focuses on injuries and diseases of your body's musculoskeletal system. This complex system includes your bones, joints, ligaments, tendons, muscles, and nerves and allows you to move, work, and be active.
Once devoted to the care of children with spine and limb deformities, orthopaedists now care for patients of all ages, from newborns with clubfeet to young athletes requiring arthroscopic surgery to older people with arthritis. And anybody can break a bone.The musculoskeletal system includes bones, joints, muscles, tendons, ligaments, cartilage, and nerves. Orthopedic doctors will care for patients of all ages from newborn babies to the very elderly.The musculoskeletal system can be thought of as the framework for our body and the mechanics that make it function. The reality is, that just about every medical specialty has some overlap with orthopedics and the musculoskeletal system.
Replacement arthroplasty is from (Greek althornmeans joint and plassein, to form or make an image of), or joint replacement surgery, is a procedure of orthopedic surgery in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. During the latter half of the 20th century, rheum surgery developed as a subspecialty focused on these and a few other procedures in patients with rheumatic diseases.
In a joint replacement, the abnormal bone and lining structures of the joint are removed surgical-ly, and new parts are inserted in their places. These new parts may be made of special metal or plastic or specific kinds of carbon-coated implants. The new parts allow the joints to move again with little or no pain.

A joint is formed when the ends of two or more bones come together. The ends of the bones in a joint are covered with a smooth layer called cartilage. Normal cartilage allows the joint to move and glide with ease. When the cartilage is damaged or diseased by arthritis, joints become stiff and painful. A total joint replacement is the removal of an arthritic or damaged joint that is then replaced with an artificial joint, called a prosthesis.
The goal of joint replacement surgery is to relieve the pain in the joint caused by the damage done to the cartilage. The pain may be so severe a person will avoid using the joint. Total joint replacement will be considered if other treatment options will not relieve the pain and disability.
