There are various causes. Your knee joint can wear down as you get older, or you might injure your knee and tear the ligament or cartilage in it. Two common conditions that cause pain behind the knee are a posterior cruciate ligament injury and a popliteal cyst (Baker’s cyst).
See our Causes of pain behind the knee section for more information.
If you injure your knee, you could try to relieve the pain by putting some ice on it – but wrap the ice in a tea towel first so you don’t hurt your skin. Put your leg up on a cushion too. If you can’t put weight on your leg, you may need crutches.
See our Self-help for pain behind the knee section for more information.
