Studies have shown that female athletes suffer ACL injuries even more frequently than do their male counterparts. There are several theories of why this injury occurs more often in women.
The real cause of this disturbing increase in ACL injuries in women is probably multifactorial. Whether female or male, ACL knee injuries can leave the athlete with a sense of instability within their knee. Ultimately it is this "giving way" or sense that the knee is "not right" that leads the patient to seek medical attention.
