Why might females be more likely to tear their ACL than males? How would you prevent this injury?
Elan Coil [88]

Answer:

Anatomical differences between men contribute to an increased risk of ACL injury.

The width of the intercondylar notch in women is smaller than in men.

The transverse area of ​​the ACL is more difficult in men, which may be a smaller diameter of the ACL in women may be a risk factor for rupture.

Additionally the  Angle Q (angle between femur and pelvis), whose normal value is 8 to 17 °, is consistently higher in women because on average, the woman's pelvis is wider and the femur shorter than in men. The existence of an increased Q angle increases the medial stress on the knee ligaments.

Finally, in female athletes, the menstrual cycle produces early changes in the synthesis of fibroblasts and procollagen type I in the ACL.

To prevent, the thigh muscles (quadriceps and ischia) and the twins must be specifically worked on. It is also necessary to train the proprioceptive mechanisms of reflex response.
