Cause of knee pain: injury or wear?
Injury or wear can cause both acute and chronic knee pain. It can occur while you are exercising (for example after jogging or when climbing stairs) or reposing. While a knee injury (for example, after a fall during sports) often causes pain in young people, knee joint wear is usually the cause of pain in older people. Other factors can also cause knee pain.
