Ryan Fussy, Teddy Bridgewater, Derrick Rose, these are just a few examples of people that have experienced the dreadful injury. Everybody wonders what really happens when athletes or someone they know goes down with an ACL injury. Ryan Fussy’s story is very simple, he was running at football practice, he planted his foot in a bad position and it all went downhill from there. Teddy Bridgewater had almost the exact same thing happen to him at highly supervised and quarterback friendly NFL practice. Derrick Rose has had multiple ACL injuries and they all resulted from awkward footing while moving at high speeds. The ACL is a blurred spot in many people’s knowledge of the body so, the increased risk of ACL injuries in females, the possible events

Trunk displacement, and specifically lateral trunk displacement, predicted risk of knee, knee ligament and ACL injuries with high sensitivity and specificity in female, but not male, athletes(Hewett). A possible reason for this not showing up in males is because of the increased stiffness of male knees is partially protective against ACL injury, especially when impulsive loads are transmitted across the knee joint(Boden). The overall positioning of the knee might also have a decent affect, as “females demonstrate greater valgus collapse of the lower extremity primarily in the coronal plane”(Hewett). Estrogen is also believed to have an effect, but the idea is heavily …show more content…
In the past medical professionals have assumed that compressive forces to the tibiofemoral joint did not increase the strain to the ACL (Boden). “However, literature published since the mid 1990s supports the concept that adding a compressive force to the knee joint, such as during the transition from non–weight bearing to weight bearing, does cause anterior translation of the tibia.” (Boden) Meaning that these studies said the ACL was under some strain. A recent study done by Simon J. Wall and his colleges suggests the same results as the experiments done in the 1990s, in which they concluded that isolated compressive forces displayed an ability to produce an ACL injury. These forces with the addition of the quadriceps force significantly reduce the force needed to result in an ACL injury
