Hip Arthritis
Description
The hip is a 'ball and socket' joint. The ends of the ball (femoral head) and the socket (acetabulum) are normally covered with a layer of smooth cartilage. If the cartilage wears out, bone will rub on bone, resulting in a stiff and painful arthritic hip.
Common Causes
Most hip arthritis is genetic, with a family predisposition. It is probably not activity related, and in fact activity may be helpful in reducing the risk of arthritis.
Symptoms
Pain when walking. Difficulty tying your shoes, or putting on socks. Difficulty with stairs, getting in and out of cars. The pain is usually felt in the groin area.
Physical Findings
Decreased range of motion of the hip, with pain on extremes of motion.
Workup
History, physical examination, and x-rays are diagnostic. X-rays show loss of hip joint space due to cartilage wear, bone spurs, and cysts. Ruling out other causes of hip pain is required.
Non-Operative Treatment
Weight control, continuing activity, anti-inflammatory medication, and the use of a cane or walker.
Surgical Treatment
Total Hip Replacement (total hip arthroplasty).
Comments
High success rate, and great patient satisfaction for joint replacement. Biggest problem is durability of the prosthesis, which wears out or loosens with time. The success rate for a redo, or revision hip replacement is not nearly so high. Therefore, this surgery should be delayed as much as possible, especially in the younger patient.
