Injuries and Conditions: Hip: Total Hip Arthroplasty

A total hip replacement procedure creates a new surface for the ball and socket mechanism of the hip. The top of the femur bone (the ball) and the acetabulum (the socket within the hip) are replaced with components constructed from metal alloys and polyethylene. The procedure is usually recommended for older patients that have advanced degenerative joint disease within the hip, resulting in severe pain and restricted mobility.
  • A hip replacement is usually performed after other treatment options have begun to show diminished effectiveness in controlling the pain of the degenerated hip, either while walking or at rest.
  • The typical candidate for a hip replacement is a patient over 55 years of age.
  • The primary goal of a hip replacement procedure is to greatly reduce pain and stiffness in the joint. The replaced hip will generally last between 15 and 20 years.
  • Surgery removes the damaged joint, and then replaces the contact or functional points of the hip and thighbone with metal alloy and polyethylene (plastic) implants.

  • Signs and Symptoms
  • Severe osteoarthritis, degenerative joint disease, inflammatory arthritis or continual and progressive discomfort and pain throughout the hip.
  • Hip pain that can no longer be managed through other treatments; pain while using the leg in normal activities, particularly intense pain while climbing or descending stairs, or during movements that put increased pressure on the hip.
  • Discomfort or pain after sitting or keeping the leg and hip motionless for an extended period of time.
  • Stiffness, which increases after the hip has remained motionless.
  • Pain at night.
  • Contact the Doctor if ...
  • Patient has signs and symptoms of severe osteoarthritis, inflammatory arthritis or degenerative joint disease.
  • Patient experiences increasing pain or weakness in the joint after treatment.
  • Patient experiences unexplained symptoms, other types of pain, or unexpected side effects of medication.

  • Common Causes of Injury
  • Osteoarthritis or other degenerative processes of the hip joint generally occur in older adults whose cartilage has worn away after years of use.
  • Replacement hips may also be suitable for patients that have suffered repeated trauma and damage to the joint, resulting in cumulative injury to the cartilage.
  • Inflammatory arthritis destroys the cartilage in the hip.

  • Expectations of Recovery
  • Hip replacement surgery usually requires a hospital stay of 3 to 5 days.
  • Rehabilitation will usually require the use of crutches, cane or a walker for 6 weeks.
  • After 3 months, the patient will likely be allowed to return to moderate athletic activity such as bicycling, golf, and swimming.
  • To help maintain the condition of the replaced hip, continued gentle use of the hip joint is encouraged. Running, pounding or impact producing activities should be kept to a minimum and undertaken with caution and common sense.
  • The initial hip replacement should last 15 or more years. Should the implants become lose, a second surgery may be required to replace or revise the implants.
