This surgery is usually considered only when bone loss, wearing of the joint surfaces, or joint loosening shows up on an x ray. Other possible reasons for revision surgery include fracture, dislocation of the artificial parts, and infection. Proper exercise can reduce joint pain and stiffness and increase flexibility and muscle strength. People who have an artificial hip should talk to their doctor or physical therapist about developing an appropriate exercise program. The doctor or therapist will decide when the patient can move on to more demanding activities.
Many doctors recommend avoiding high-impact activities, such as basketball, jogging, and tennis.
These activities can damage the new hip or cause loosening of its parts. Some recommended exercises are cross-country skiing, swimming, walking, and stationary bicycling. These exercises can increase muscle strength and cardiovascular fitness without injuring the new hip. To help avoid unsuccessful surgery, researchers are studying the types of patients most likely to benefit from a hip replacement. Researchers also are developing new surgical techniques, materials, and designs of prostheses, and studying ways to reduce the inflammatory response of the body to the prosthesis.
