Ligamentous Injury

The knee is held together by bands of tissue known as ligaments. These provide stability to the knee. The ligaments on either side of the knee are called collateral ligaments (medial and lateral), and the two ligaments on the inside of the knee are called cruciate ligaments (anterior and posterior). The Anterior Cruciate Ligament (ACL) is one of the most commonly injured ligaments, often occurring as a result of a pivoting or twisting injury during sport. This can leave the knee feeling unstable, with an inability to return to sport or other normal activities. It is possible to injure more than one ligament at a time, making for a more complex injury and increasing the potential for ongoing instability.
