There are no blood vessels inside of the hyaline cartilage, the alimentation is performed per diffusion. The knee permits flexion and extension about a virtual transverse axis, as well as a slight medial and lateral rotation about the axis of the lower leg in the flexed position. Within a few weeks of pain management, icing and elevation, the stiffness usually subsides and greater range of movement is experienced. With the leg held close to the knee joint, steady progressive pressure is applied until the surgeon can hear and feel the adhesions breaking away. A completely torn tendon requires surgery but a partially torn tendon can be treated with leg immobilization followed by physical therapy.
