ABSTRACT
The knee is a frequently injured joint in athletic and recreational activities. According to some statistics, one half, or possibly even more, of all sports-related injuries are incurred in the knee joint. The precise statistics differ between various athletic activities and depend on the specific movements habitually performed in these activities. Overuse injuries are also frequent in the knee joint; the reasons for this are that the knee joint participates in all sports activities (running, jumping, kicking, etc.) and that its joint area is characterized by numerous attachment sites for muscles and their tendons as well as by numerous bursae. It is also because of the nature of the specific joint between the patella and the femur (articulatio femoropatellaris) that constitutes a part of the knee joint.
