Question

Quizplus · Accepted Answer

The anterior cruciate ligament (ACL) is most often injured during activities that involve sudden stops or changes in direction, jumping, and landing. This typically occurs during deceleration with the knee in a valgus position (knee collapsing inward) and the tibia internally rotated. This combination of movements puts excessive stress on the ACL, leading to potential injury.
