Hip arthritis

Mr Prakash specialises predominantly in knee and hip joint surgery especially for young adults (age 20-65). He routinely performs surgery related to sports injuries and arthritis including Hip Arthritis.

This is thought to be caused by the process of “wear and tear” of the articular cartilage. It may be predisposed by:

• Obesity
• Fracture of a bone going through the joint
• Articular cartilage damage from any injury
• Abnormal loading, for example misshapen joint
• Certain sporting activities, for example, prolonged running
• Family history

Damage to the articular cartilage is progressive. Eventually it may become completely worn away in patches, exposing bare bones, which then may rub against each other, thereby causing pain. Debris of cartilage floating in the joint may also cause irritation and inflammation in the joint lining and this is a second source of pain. One may feel the joint to ‘grind’.

X-rays show narrowing of the ‘joint space’ along with other features of arthritis. There is no blood test for osteoarthritis.

This is a systemic disorder, which means that it affects various organs of the body apart from the joints.

The inflammation starts in the lining of the joint (synovium) and eventually destroys the joint cartilage. In this condition the bones become soft. Rheumatoid arthritis affects many joints simultaneously, including the small joints of the hands. There are other variants of rheumatoid arthritis, but these are essentially similar in nature.

X-ray changes in RA are similar to osteoarthritis in terms of joint space narrowing but the pattern may be different. There is usually a loss of bone density.

Blood tests for rheumatoid arthritis are not very accurate.
