@instituteofhumananatomy: 70% of ACL tears happen with zero contact. Here is why. Your ACL does two big jobs in the knee: it resists excessive internal rotation and it limits hyperextension. Push the knee too far in either direction, or a combination, and the ligament can tear. Contact can do it, like a hit to the lower leg in football, but most ACL tears are non-contact: a bad landing from a jump, or a plant and twist, and it pops. Degrees matter too. Micro tears in the collagen fibers often mean physical therapy. A full tear, if you want to keep competing, usually means surgery. Want the knee and lower limb at this depth?

i tore mine playing beach volleyball. was jumping up, and it popped on the jump up. i think it happened because i twisted as i jumped, and as the sand gave way below me, it twisted more. would not reccomend 😅
