Knee injuries are common injuries in most sports, commonly seen in football, soccer, basketball, and baseball. We have all heard of one of our favorite athletes sustaining a “knee injury,” however these injuries can range anywhere from meniscal tears and cartilage damage to tendon or ligament injuries. The knee joint is a large but simple joint. Unlike the shoulder and hip joint the knee joint basically functions as a hinge, creating both flexion and extension. The knee does have a rotational component as well. The function of the knee joint is heavily reliant on its strong muscles, tendons and ligaments. Tendons are strong bands of fibrous tissue that connect muscle to bones across joints in order to affect motion. Ligaments are strong fibrous bands that connect bone to bone across joints to help stability. (Figure 1) They prevent abnormal motion in any direction. By maintaining normal joint motion, these tendons and ligaments also protect the cartilage of the knee. This is perhaps one of their most important roles, as cartilage lines the surfaces of the bones within the joint, allowing for smooth, frictionless joint motion. When this joint cartilage is damaged, significant pain results. In fact, the definition of osteoarthritis (“arthritis”) is damage or loss of this joint surface cartilage.
