Hip replacement(arthroplasty) is a surgical procedure that replaces diseased parts of the hip joint with new, artificial prosthesis. Hip replacement surgery improves both mobility and comfort in a painful hip joint.

The most common reason for hip replacements is osteoarthritis of the hip joint. Other disease may also result in a hip replacement when pain and lose of function limit one's daily activities or quality of life.

Before deciding on a replacement, physicians may recommend medications, such as, Nonsteroidal anti-inflammatory drugs, or exercise to strengthen the muscles in the hip joint.

A hip replacement surgery is done by removing diseased tissue and replacing them with artificial parts. Hip replacement surgery usually lasts 2 to 3 hours recovery depending upon the patient's health status.

Physical therapy is required for a fast return to activity. A physical therapist will prescribe exercises that strengthen the hip. Exercise can also reduce joint pain and stiffness and increase flexibility. Many doctors recommend avoiding high-impact activitiesafter surgery. Ideal exercises are low-imapct: cross-country skiing, swimming, walking, and bicycling. These exercises can increase muscle strength and cardiovascular fitness without injuring the new hip.
