The most common knee ligament injuries often involve the medial aspect of the knee. Within this area, there are several crucial anatomical structures, with the medial collateral ligament (MCL) standing out as the largest and strongest. Many isolated MCL injuries to the medial knee are a result of sports-related activities. These injuries can occur due to either direct contact or non-contact stress applied to the outside of the knee, which can lead to stretching or tearing of the medial knee structures located on the inner side.
