Noncontact anterior cruciate ligament (ACL) injuries often occur during unbalanced jump landings with most body weight on the injured leg, 1 – 4 and females have higher incidences of ACL injuries compared with males in most sports events. 5 – 7 In vitro and in vivo studies have shown that

The anterior cruciate ligament (ACL) is a commonly injured ligament in the body, often but not always requiring operative intervention. 1 The incidence of ACL reconstruction continues to rise, increasing by 20% over the last decade, with the most rapid increase occurring in patients aged between

Clinical Scenario A common injury among elite, recreational, and youth athletes is the anterior cruciate ligament (ACL) tear. 1 Approximately 200,000 ACL injuries occur every year. 2 The gold standard in ACL injury evaluation is diagnostic arthroscopy 3 , 4 ; however, the diagnostic accuracy of

Joint loading following anterior cruciate ligament reconstruction (ACL-R) continues to be a topic of interest among researchers, because altered joint loading can contribute to compensatory movements, commonly seen in this patient population. Joint loading has been examined using a variety of

Anterior cruciate ligament (ACL) injuries are among the most common knee-related injuries sustained by physically active individuals. 1 A recent population study from the United States demonstrated an overall estimated incidence of 69 ACL injuries per 100,000 person years. 2 Younger individuals

Injury to the anterior cruciate ligament (ACL) is one of the most common knee injuries to occur during athletic participation. 1 It is estimated that up to 250,000 ACL injuries occur each year in the United States, with roughly 130,000 of the injured individuals electing to undergo surgical

Nearly 200,000 anterior cruciate ligament (ACL) tears occur yearly in the United States, with up to 90% resulting in reconstructive surgery. 1 Although various surgical methods and rehabilitation protocols have been utilized with the intention of improving patient outcomes following anterior

Athletes are particularly at risk for anterior cruciate ligament injury, and there is some evidence that female athletes are more at risk than males. The conflicting principles of stability and mobility are at odds within the knee, setting the stage for potentially serious injuries. Some investigators suggest that the size of the intercondylar notch should be used to identify athletes at risk for ACL damage, but more research is required before clinical decisions can be based on notch width measurements. Athletic shoe modifications and artificial playing surfaces may influence the incidence of ACL injures. Functional knee braces appear to have beneficial strain shielding effect on the ACL for anterior directed loads and internal–external torques applied to the tibia, but this effect appears to decrease as the magnitude of these anterior directed loads and torques increases. Ski equipment is often pointed to as a contributing factor in ACL injuries, but there is no evidence that modifications in ski equipment will decrease ACL disruptions. An education program based on recognizing the events that lead to ACL injury in skiing may reduce knee injuries in the future.

Clinically, anterior cruciate ligament (ACL) injuries are hypothesized to occur within 50 milliseconds of initial contact with the ground during landing tasks. 1 This rapid loading of the ACL is corroborated by in vitro simulation, which has shown that ACL strain immediately increases and peaks
