Causes of knee OA

There are a number of different things that can contribute to osteoarthritis of the knee, and the rate at which it progresses over time can vary because of them.

Age

 

The degeneration or gradual break down of knee cartilage is often due to the normal ageing process.

Past injury to the knee

 

Knee injury, especially to your ligaments, can cause normal degeneration to start much earlier or progress more rapidly.

Those who have torn their anterior cruciate ligament or ACL, are at a 50% risk that they will develop knee OA within the next ten years.

Body weight

 

Extra weight often accelerates the degenerative process and increased body weight is one of the biggest risk factors for knee OA.

Family history

 

If there is a family history of arthritis, that may play a part in whether someone will get the disease or not.
