How can overuse contribute to stay apparatus injuries?

• A. Decreases injury risk
• B. Repetitive loading causes microtrauma to suspensory ligaments and distal sesamoidean ligaments, increasing injury risk
• C. No effect
• D. Strengthens ligaments

Answer: (B)

Overuse stresses the stay apparatus with repeated cycles of loading, so the suspensory ligaments and distal sesamoidean ligaments keep taking small hits with every stride or stand. This repetitive microstrain causes microtrauma to these ligaments. When this microdamage accumulates faster than the tissues can repair, their structural integrity declines and inflammation or degeneration can set in, heightening the risk of injuries to these ligaments. So, ongoing overuse increases injury risk because the ligaments are repeatedly damaged beyond their capacity to heal promptly. The idea that overuse would reduce risk, do nothing, or strengthen ligaments isn’t accurate—chronic repetitive loading tends to wear them down rather than fortify them.
