The main reason for hip revision surgery is to repair an artificial hip implant that may be no longer securely attached to the bone, resulting in abnormal motion that causes pain for the patient. Hip revision surgery is an attempt to repair the hip and restore it to a condition where it can function normally.

The term total hip replacement  is somewhat misleading. The hip itself is not replaced, as is commonly thought, but rather an implant is used to recap the worn bone ends. The head of the femur is removed. A metal stem is then inserted into the femur shaft and topped with a metal or ceramic ball.
The worn socket (acetabulum) is smoothed and lined with a metal cup and either a plastic, metal, or ceramic liner. No longer does bone rub on bone, causing pain and stiffness.

Relief from pain is the main benefit of having hip revision surgery. Many patients may find that hip revision surgery improves mobility, strength and coordination of the torso and leg, in addition to improving the appearance of the hip and leg. Revision surgery may enable patients to return once again to normal activity with a pain-free hip. But keep in mind that successful hip revision surgery  is also contingent on the patient’s diligence with his or her rehabilitation program following surgery.

Keep in mind that hip revision surgery is a voluntary, but safe procedure. Unforeseen complications may develop that are associated with anesthesia, such as respiratory or cardiac malfunction. In addition, complications may arise with an infection, injury to nerves and blood vessels, fracture, weakness, stiffness or instability of the joint, pain, or the possibility of needing more hip surgeries.

Joint cartilage is a tough, smooth tissue that covers the ends of bones where joints are located. It helps cushion the bones during movement, and because it is smooth and slippery, it allows for motion with minimal friction.
Osteoarthritis, the most common form of arthritis, is a wear and tear condition that destroys joint  Sometimes, as the result of trauma, repetitive movement, or for no apparent reason, the cartilage wears down, exposing the bone ends. Over time, cartilage destruction can result in painful bone-on-bone contact, along with swelling and loss of motion. Osteoarthritis usually occurs later in life and may affect only one joint or many joints.
