HIP ARTHRITIS: Arthritis is a general term covering numerous conditions where the joint surface (cartilage) wears out. The joint surface is covered by a smooth articular surface that allows pain free movement in the joint. This surface can wear out for a number of reasons. Often the definite cause is not known. When the articular cartilage wears out, the bone ends rub on one another and cause pain. There are numerous conditions that can cause arthritis and often the exact cause is never known. In general, but not always, it affects people as they get older (osteoarthritis).


The cartilage lining is thinner than normal or completely absent

  • The degree of cartilage damage and inflammation varies with the type and stage of arthritis
  • The capsule of the arthritic Hip is swollen
  • The joint space is narrowed and irregular in outline; this can be seen in an X-ray image
  • Bone spurs or excessive bone can also build up around the edges of the joint
  • The combinations of these factors make the arthritic Hip stiff and limit activities due to pain or fatigue

Diagnosis: The diagnosis is made on history, physical examination and X-rays. There is no blood test to diagnose the wear and tear of Hip arthritis.

Indications: Total Hip Replacement (THR) is required for arthritis of the Hip that has failed to respond to conservative (non-operative) treatment.

You should consider a THR when you have

  • Arthritis confirmed on X-ray
  • Pain not responding to analgesics or anti-inflammatory
  • Limitations of activities of daily living (ADL) including your leisure activities, sport or work and Morning Walk.
  • Pain that keeps you awake at night (Night Cry)
  • Stiffness in the Hip making mobility difficult while doing your normal activity like getting into car, climbing steps, sitting in chair or Sofa etc

What is hip replacement? Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. This is generally conducted to relieve arthritis pain or fix severe physical joint damage as part of hip fracture treatment. A total hip replacement (total hip arthroplasty) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head.

Hip replacement or total hip arthroplasty, involves removing a diseased hip joint and replacing it with an artificial joint, called prosthesis. Hip prosthesis consist of a ball component, made of metal or ceramic, and a socket, which has an insert or liner made of plastic, ceramic or metal. The implants used in hip replacement are biocompatible — meaning they’re designed to be accepted by your body — and they’re made to resist corrosion, degradation and wear.

Is Hip Replacement Surgery for You? The decision to have hip replacement surgery should be a cooperative one made by you, your family and your orthopedic surgeon. Recommendations for surgery are based on a patient’s pain and disability, not age or weight. Most patients who undergo total hip replacement are age 50 to 80, but orthopedic surgeons evaluate patients individually. Total hip replacements have been performed successfully at all ages, from the young teenager with juvenile arthritis to the elderly patient with degenerative arthritis.
