The term "ACL" stands for Anterior Cruciate Ligament, which is a crucial ligament located in the knee. It connects the thigh bone (femur) to the shin bone (tibia) and plays a vital role in stabilizing the knee during movement. Injuries to the ACL are common, especially in sports that involve sudden stops or changes in direction, like soccer or basketball. When an ACL injury occurs, it can lead to pain, swelling, and difficulty in moving the knee. Many athletes seek treatment options, which may include physical therapy or even surgery to repair the ligament. Proper rehabilitation is essential for a full recovery and to prevent future injuries.
