Kissing contusions are defined as relative bone contusion patterns in the tibia and femur and have been the focus of research into anterior cruciate ligament injury mechanisms (18). The knee is a hinge joint and as such relies heavily on a complex system of soft tissue structures for support and stability. Cruciate ligament reconstruction and meniscal surgery are frequently performed for restoration of knee joint stability and function after cruciate ligament and meniscus injuries, and they contribute to the prevention of secondary osteoarthritis. (The colloquial expression "cartilage damage" might also include meniscal tears, which is an altogether separate category of disease.) An example is a twisting knee injury in basketball or skiing. Patients typically present with symptoms of knee instability, usually after acute trauma. Eighty-nine occult fractures were identified in 56 knees.
