## More about Knee

The knee carries the body’s weight with every step and most often hurts from overuse, wear of the cartilage or a sports injury.

Where the pain is and how it started help to find the cause. Pain at the front, around the kneecap, is common in young people and runners. Pain on the inner side after the age of 50 is usually osteoarthritis. A pop, rapid swelling and a knee that gives way suggest a torn ligament.

### When to start with a consultation

For pain without an injury that lasts more than 1–2 weeks, start with a consultation. After an injury with rapid swelling, with a locked knee, or if you can’t put weight on the leg, see an orthopaedic doctor first.
