When do ligamentous injuries typically occur?

Ligaments are passive stabilizers that limit how far a joint can move. A ligamentous injury usually happens when the joint is moved passively into more than its normal range of motion, allowing the ligament fibers to be overstretched or torn (a sprain). Active muscle contraction tends to stabilize the joint and lessen ligament strain, so injuries from muscle action are less typical. Repetitive impact with the ground is more associated with overuse injuries to bone, tendon, or cartilage, not an acute ligament tear. Sudden joint compression loads the joint surfaces and capsule rather than overstretching ligaments. Therefore, the typical mechanism is a passive stretch into excessive ROM.
