Anterior Cruciate Ligament Injury

An anterior cruciate ligament (ACL) injury involves damage to one of the key ligaments that stabilize the knee joint. The ACL connects the thigh bone (femur) to the shin bone (tibia) and helps prevent the knee from sliding forward or turning excessively. Such injuries often happen during activities that involve sudden stops, pivots, or changes in direction, especially in sports like soccer, basketball, or skiing. Symptoms include a loud pop, swelling, pain, and a feeling of instability. Treatment may involve physical therapy or surgery, depending on the injury’s severity, to restore knee stability and function.
