WHAT IS A POPLITEAL CYST?
A popliteal cyst is a benign fluid-filled lump that appears at the back of the knee in some children. It connects with a cyst that we all have at the back of our knees. This cyst oils the hamstring tendons as they move over the back of the knee so they don't fray through. The cyst has a fancy name - the semi-membranosis bursa - but most people find "popliteal cyst" less of a mouthful!
Your child has been referred to the clinic with either bow-legs or knock-knees. This leaflet has been prepared to help you learn more about these related conditions. Bow-legs means that there is a gap between the knees when the ankle bones are pressed together. Knock-knees are present when there is a gap between the ankle bones with the knees are pressed together.
ARE BOW-LEGS OR KNOCK-KNEES ABNORMAL?
NOT IN MOST CHILDREN.
WHAT IS KNEECAP PAIN?
Kneecap pain is pain that comes from the kneecap or patella. It is usually felt at the front of the knee though it sometimes seems to spread around the sides and occasionally to the back of the knee. Many different names have been given to this type of knee pain including anterior knee pain, chondromalacia patellae and patello-femoral pain. Patello-femoral pain is most in favour at present with doctors.
