Abstract：The knee joint is the largest joint in the human body, sustaining the body weight and allowing legs to bend and straighten. An estimation of 70% Anterior Cruciate Ligament (ACL) injuries occurred during jumping, stopping suddenly, and changing directions and 70% of those injuries were through the non-contact mechanism. Athletes with ACL injuries usually need more than 6 months of treatment and rehabilitation before returning to the sport. Nowadays, countries all over the world strive to prevent and reduce ACL injuries. The prevention program for ACL injuries may reach the effects to some extents regardless the length of intervention. However, if the intervention program takes far too long, athletes may feel bored. A short and efficient program is often preferred and executed by most sport teams. Future research directions could promote the effective prevention program among high schools, universities, or club teams and investigate the efficiency in reducing ACL injuries. (Full text)
