Most ACL injuries are non-contact.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

The statement is true. In many sports, the majority of ACL injuries occur without any direct contact. The common scenario involves rapid deceleration, a change of direction or pivot with a planted foot, and knee positions that place the ligament under high anterior tibial shear and valgus/rotational stress. This combination can tear the ACL during landing or cutting moments, often with near hyperextension or knee valgus. While contact injuries do happen when a direct blow or collision injures the knee, they are less frequent overall compared to the non-contact mechanism. Understanding this helps emphasize the importance of training focused on cutting and landing mechanics, neuromuscular control, and strength to reduce the risk of non-contact ACL tears.
