Patients who have had an artificial joint implanted in their hip are usually people aged 55 or older who developed severe and debilitating arthritis in the hip joint. Revision surgery is an attempt to correct the problem in order to get the hip back to a condition where it can function normally. When an artificial joint is no longer securely attached to the bone, it is commonly because the bone absorbs next to the prosthesis thus, new abnormal motion occurs, resulting in pain on weight bearing.

As a free-moving joint in the body, the normal hip can move backwards and forwards, from side-to-side, and can perform twisting motions.Īrtificial joints do not last forever, and many show signs of loosening after a period of 10-15 years. The human hip, is a ball and socket joint, in which the ball of one bone (the femur, or bone of the upper leg) fits into the socket of another (the pelvic bone). Sometimes this is a long process involving more than one surgical procedure, and is certainly more taxing than the original replacement surgery. With revision surgery the original prosthesis is removed and replaced with a new one. In hip replacement surgery the diseased portions of the hipbones are cut away and replaced with a two-part prosthesis, or artificial hip joint. They can be extremely effective in improving hip joints that have been severely damaged by injury or arthritis. The use of artificial hip implants has become quite widespread in recent years. Hip revision surgery involves the repair of an artificial hip joint that has been damaged or loosened over time or as the result of infection.
