![]() The procedure is usually performed under spinal anesthesia in combination with a nerve block. ![]() Total joint replacement surgery usually takes one to two hours and is typically performed in a hospital setting with a one- to two-day hospital stay. Like hip replacements, knee replacements can either be cemented into place or are covered in a special material into which the bone will grow. The major ligaments and tendons of the knee are typically kept in place to provide stability and normal motion of the knee joint. The surfaces of the bone are then shaped with tools and sized to allow an appropriate implant fit for each individual knee. The prostheses and implants come in a variety of shapes and sizes that can be tailored to the individual.ĭuring total knee replacement surgery, a thin amount of bone along the surface of the joint is removed from the end of the femur or thigh bone, the top of the tibia or leg bone, as well as the underside of the kneecap. A plastic liner is then snapped into the metal cup and rotates with the new ball on the end of the femoral stem. The socket portion of the ball and socket joint is also replaced with a metal cup that is placed into the pelvis. In some instances, however, the prosthesis is cemented into the bone. The prosthesis is usually coated with a special material into which the bone will grow over time. Both procedures are very successful at eliminating pain, correcting deformity and improving patient mobility so patients can regain quality of life and get back to the activities they enjoy.ĭuring hip replacement, the damaged ball of the hip ball and socket joint is removed and replaced with a metal or ceramic ball that attaches to a stem that fits into the femur. Hip and knee replacement are two of the most commonly performed operations in orthopedic surgery. What Happens During Joint Replacement Surgery Joint replacement is performed only after other conservative treatments have failed such as medications, physical therapy, and injections. There are, however, other causes of joint pain that may also lead to joint replacement including hereditary disorders, developmental problems, and trauma. The most common conditions that lead to joint replacement surgery are osteoarthritis and rheumatoid arthritis. Over time this cartilage can break down, leading to bone-on-bone friction which can cause inflammation and pain. The surfaces of the bones are covered with cartilage to form a normal smooth gliding joint. The prosthesis is designed to reproduce the shape and motion of the normal joint.Ī joint is an area in the body where two or more bones join together to allow motion. ![]() Total joint replacement is a surgical procedure where parts of an arthritic or damaged joint are removed and replaced with a metal, plastic or ceramic device called a prosthesis or implant. ![]()
