There are more than 100,000 ACL tears/year in the U.S. ACL tears generally result in surgery, extensive physical therapy, significant time away from an athlete’s sport and friends, and a likelihood of arthritis within 10 years after injury. Most ACL injuries occur without contact, while landing or cutting. For this reason, the highest prevalence of knee injuries occur in soccer, lacrosse, basketball, volleyball, and field hockey. Females are up to 10 times more likely than males to have an ACL injury, playing the same sport. There are multiple reasons for this, but research studies have shown that neuromuscular training to improve landing mechanics can reduce the relative injury risk from 24 to 82 percent.

MedStar NRH-MedStar Harbor Hospital Sports Medicine has developed a comprehensive program to reduce injury risk. In the clinic, this involves learning a proper dynamic warm up, a targeted strengthening program, as well as a progressive plyometric program. Our mission is to help educate and train as many teams, coaches, and parents as possible to help minimize the risk of an athlete suffering this common injury.
