This facilitates attachment of the ligament of the head of the femur (also called the ligamentum fovea or ligamentum teres). These vessels are not as vulnerable as those at the neck of the femur. The tibia also has a mechanical axis (the mechanical axis of the tibia) which runs from the knee joint line to the center of the ankle joint. This problem has been solved! As the method of injury is typically high energy, the surrounding soft tissues may also be damaged.
