Osteoarthritis (OA) is the most common form of arthritis, and is the result of wear and tear of the joint surfaces as part of the natural ageing process. When OA affects a joint, the cartilage between the two surfaces becomes damaged and worn causing inflammation.

Symptoms
OA hip is characterised by pain and stiffness around the hip joint and groin. Pain is also commonly referred to the knee joint. The symptoms usually develop gradually over months or years, and as the condition progresses the symptoms can become more constant. Loading of the hip joint will become painful as the surfaces wear away, so commonly one of the symptoms is the development of a limp when walking.

Causes

• Age - Commonly OA begins in the late 40's, 50's or 60's as part of the natural ageing process.
• Obesity - If you are overweight then the loading of the joint is increased causing greater wear and tear. If you remain overweight, then this will potentially worsen the condition.
• Joint Injury - A major injury or operation on a joint can lead to an increased risk in OA. Heavy, repetitive activity may also increase the risk of developing the condition.
• Genetics
