I tore my anterior cruciate ligament 4 days ago now. do i require surgery?

Discuss w/ Ortho MD: Most torn acls eventually require surgical reconstruction in young active patients who desire to return to any sort of activities that require changing direction or quick starting and stopping. A thorough examination of your knee detailing any other concomitantly injured structures (meniscal tear, cartilage injury, etc.) will also dictate your indication and timing for potential acl surgery.
