Knee Ligament Injuries

Learn about knee ligament anatomy with this interesting sports injury video. The four main ligaments that stabilize the knee are known as the anterior cruciate ligament (ACL), posterior cruciate ligament, medial collateral ligament and lateral collateral ligament. Damage to the ACL is the most common knee ligament injury among athletes and can take a long time to repair after surgery and reconstruction of the knee. ACL tears can be common in sports that require sharp cutting and twisting motions such as basketball, American football and soccer.
