How does the knee work?
The knee is the largest joint in your body.
It is made up of four main things: bones, ligaments, cartilage and tendons. The knee bends and straightens and has a small amount of rotation to allow for day to day activities.
Most of the time there is a very simple explanation for knee pain.
If you’ve overdone it while exercising pain is usually caused by strained or inflamed soft tissues, such as joint surface or tendons and it often clears up within a few days to weeks.
As you get older, pain in your knee can flare up now and again, often for no reason.
If you have previously had a partial or full knee replacement and have developed new or unusual knee pain several years after having the operation please arrange an appointment to discuss with your GP.
If you’ve fallen and/or twisted your knee and it becomes immediately swollen, your knee has locked (your unable to move it at all because it is stuck) and you're finding it difficult to put weight on your leg you may need to see a doctor.
You should urgently call 111 who will triage if you need urgent care, as there is a small possibility of a bone or ligament injury
It can take 4 to 6 weeks to recover fully from hip pain.
