If your hip has been damaged by arthritis from any cause, common activities such as walking or getting in and out of a chair may be painful and difficult. You may even feel uncomfortable while resting. Medication may control your pain for a short while but long term use of pain killers is not likely to do any good to your stomach. You may therefore want to consider hip replacement surgery. By replacing your diseased hip joint with an artificial joint, hip replacement surgery can relieve your pain and help you get back to enjoying normal, everyday activities.

Common Causes of Hip Pain and Loss of Hip Mobility
The most common cause of chronic hip pain and disability is arthritis. Osteoarthritis, rheumatoid arthritis, and traumatic arthritis are the most common forms of this disease.

Osteoarthritis usually occurs after age 50. The articular cartilage covering & cushioning the bones of the hip wears away. The bones then rub against each other, causing hip pain and stiffness.

Avascular Necrosis is a common condition leading to secondary Osteoarthritis. The blood supply to the ball part of the joint (femoral head) is cut off due to various reasons and this leads to weakening of the bone and eventually arthritis. Steriod use, warranted or unwarranted, is the most common cause in India.

Rheumatoid Arthritis is a disease in which the synovial membrane becomes inflamed, produces too much synovial fluid, and damages the articular cartilage, leading to pain and stiffness.

Traumatic Arthritis can follow a serious hip injury or fracture. A hip fracture can also cause avascular necrosis described above.
