Patients with severe joint degeneration have significant pain, stiffness, loss of motion and function. The cartilage on the joint surfaces has been eroded and X-rays may reveal a loss of joint space and “bone-on-bone” contact. Joint replacement is normally the only treatment option available at this point. Following a joint replacement, the artificial hip will be different from the natural joint and there will be some limitations of motion and function. However, a patient’s quality of life is usually significantly improved following a total joint replacement. Recovery following hip replacement can take 3-4 months of intensive physical therapy and rehabilitation. Improvements and functional gains can continue to develop for up to a year following the procedure.
