ACL is key for stability and movement in the knee. injuries frequently happen during athletic play, especially with sudden cuts, sudden stops, or jumps, including soccer, basketball, and tennis. minor injuries may not produce much swelling or sound, but serious injuries may cause a loud popping sound and substantial swelling. Women are more prone than the men, because of factors including anatomy, muscle strength, and playing style. rehabilitation and reconstruction surgery are typical treatments for ACL injuries, with the goal of restoring knee function and strength.
