Knee Anatomy
The knee is the largest joint in the body, and one of the most commonly injured. It consist lower end of the thigh bone (femur), which moves on the upper end of the leg bone (tibia), and the knee cap (patella) in the front, which slides in a groove on the distal end of the femur (Trochlea).These bone ends ar covered with thick cartilage. The knee also contains many ligaments which stabilise the joint against abnormal types of motion. Another important structure is the meniscus, it is a semi lunar shaped wedge of soft cartilage between the femur and tibia that serves to cushion the joint surfaces and helps it absorb shock during motion and protect the articular cartilage.
