A healthy knee has cartilage and lubricating fluid (synovial fluid) to protect and cushion the bones, allowing the knee to move and bend.
In knee osteoarthritis, it is a condition which the cartilage wears away, and the joint fluid loses its shock absorbing qualities. If this happens, the bones may rub each other and resulting pain, stiffness and swelling.
Who are at risk of knee osteoarthritis?
The people who tend to have knee osteoarthritis are:
i) Elderly (aging process)
ii) Previous knee injury
iii) Repetitive strain on the knee
iv) Fractures, ligament tear, and meniscal injury which can affect ligament and promote wear and tear
