The Anterior Cruciate Ligament is key for stability and movement in the knee. Injuries often occur during athletic play, especially with quick direction changes, sudden stops, or leaps, like soccer, basketball, and tennis. less severe injuries may not lead to much sound or swelling, but serious injuries may cause a loud popping sound and major swelling. Women are more prone than the men, due to factors like anatomy, muscle strength, and playing style. physical therapy and reconstructive surgery are common treatments for ACL injuries, with the goal of restoring knee function and strength.
