Usually, an ACL tear takes place in a non-contact circumstance, with 70% occurring in non-contact and 30% occurring with direct contact. Over 150,000 ACLs are torn annually in the USA alone, according to the Orthopedic Sports Society for Medicine. They also report that over $500 millions in health costs are spent annually reconstructing ACLs. The ACL is most likely torn between the ages 15 and 45 years of age mainly because of patients more energetic and active lifestyles. Also, people of this age take part in more sporting activities than others. The tear occurs typically when a person’s knee is unstable due to deceleration, pivoting, cutting, jumping, or side stepping while out of control. A popping noise is most times heard or felt by those who have torn their ACL during the time of the accident. In general, patients are unable to continue sporting and regular activities once torn. After an ACL is torn, all range of motion is lost, along with sensitivity near knee joints, discomfort while moving, and high instability. Surgery is almost always required to repair a torn ACL. Almost half of all ACL injuries occur with damages to the meniscus, MCL, cartilage or other ligaments surrounding the …show more content…
Males only have a higher incidence of ACL’s torn because of the higher participation in male sports than women. The most common sport associated with ACL injury because of direct contact is football. Other common sports associated with injury are basketball, skiing and soccer. Despite males having a higher incidence of ACL tears, athletes who are females are 2-8 times more likely to experience an ACL tear while participating in sports, especially in basketball and soccer. In fact, there are several risk factors that are thought to increase the risk of ACL injury in women include: lower extremity alignment, joint laxity, ACL size, hormonal differences, and hamstring flexibility. The physical condition, muscular strength and the increased looseness of ligaments in women also are causes of why women have an increased risk of tearing their ACL. Women have a strength imbalance between the quadriceps and the hamstrings, typically, a female’s quadriceps are stronger than their hamstrings, causing an imbalance of the muscles leading to an increased likelihood of tearing an
