ACL injuries are some of the most common injuries in sports medicine. There have been several ACL prevention protocols developed over many years, however, they can be burdensome to implement due to the amount of time required and number of exercises to perform. Dr. Marshall and Dr. Keller have developed a simple prevention program designed to be added to pre-season conditioning programs and become a part of pre-practice workouts. The exercises take about 5 minutes to perform. The goal is to improve hamstring flexibility, quadriceps/hamstring/hip abduction strength, to improve knee stability and landing mechanics. The main goal is to avoid dynamic valgus of the knee during competition. Although ACL injuries cannot be completely prevented, the goal is to decrease the risk.
