The knee is the largest joint in the body and a major weight-bearing joint which all contributes to it being one of the most frequently injured joints in the body.
The knee joint lies between the thigh bone (femur) and shin bone (tibia) and at the front is the kneecap (patella). It is made up of a number of structures including ligaments, muscles, joint capsule, and two ‘c’ shaped pieces of cartilage or menisci which sit between the thigh and shin.
The causes of knee pain can be divided into two main areas with problems caused by local structures in the knee itself or knee pain due to problems with surrounding joints.
