About Joint Replacement

Your Hip Joint

A joint is formed by the ends of 2 or more bones. The hip must bear the full force of your weight and consists of two main parts:

  • A ball (femoral head) at the top of your thigh bone (femur)
  • A rounded socket (acetabulum) in your pelvis

Normal hip joint, showing healthy articular cartilage

Diseased hip joint, showing worn cartilage

What Causes Hip Joint Pain?
One of the most common causes of joint pain is arthritis. The most common types of arthritis are:

  • Osteoarthritis (OA)
  • Rheumatoid Arthritis (RA)
  • Post-traumatic Arthritis
  • Avascular Necrosis

Hip Surgery
May be suitable for patients who:

  • Have a painful, disabling joint disease of the hip resulting from a severe form of arthritis
  • Are not likely to achieve satisfactory results from less invasive procedures, medication, physical therapy, or joint fluid supplements
  • Have bone stock that is of poor quality or inadequate for other reconstructive techniques
