Tibial collateral ligament

The tibial collateral ligament is also called the superficial medial collateral ligament. It is about eight to nine centimeters long and stretches from femur's medial epicondyle to the two attachments on the tibia bone. It is a flat, band-like thickening object located on the knee's medial aspect. This strong band is under the insertions of the gracillis, sartorius, and semitendinosus. The ligament reinforces the knee's articular capsule's medial surface. It is attached to the medial meniscus. This has clinical relevance because if it the knee suffers a knee an excessive abduction, which is a clipping-type injury, both the medial meniscus and the tibial collateral ligament will tear. As one of the four major ligaments in the knee, such an injury can take a long time to heal. Damage to the ligament can occur due to high impact, bending, or landing on a slightly bent knee and is very painful. A grade one injury may take two to ten weeks to heal, while a grade two or three injury could take months. Skiing and American football are the most common sources for injuries to this ligament.
