Recently, there has been a dramatic rise in the number of children participating in competitive sports. Adolescents involved in sports that require cutting, pivoting or body contact are at greatest risk for sustaining an anterior cruciate ligament (ACL) rupture of the knee, however, appropriate management remains controversial. The surgical technique is commonly performed in the adult population has been associated with risks for growth disturbance when performed on skeletally immature individuals. Therefore, the recommended standard of care in children is to initially follow a non-surgical management protocol that allows a patient to skeletally mature prior to ultimately receiving surgical reconstruction. Unfortunately, current non-surgical management protocols are ineffective at enhancing knee joint stability and dynamic function. There has been no research to indicate the most appropriate exercise program for the ACL deficient skeletally immature individual. A neuromuscular exercise program proven to be safe and effective in the ACL deficient adult population is perturbation training. In adolescents, research suggests neuromuscular exercises can reduce the rate of ACL injuries by 50%. However, currently there is no research investigating the benefits of a neuromuscular exercise on the management of a skeletally immature ACL-deficient individual. The results of this investigation will provide researchers and clinicians valuable information on the effect of neuromuscular perturbation exercises on knee joint stability and function immediately following injury. This has the potential to minimize the development of secondary meniscal tears and premature joint degeneration commonly demonstrated following an ACL injury.
