“…II). The resulting peak relative AM-ACL strain ranged from 9.4 to 27%, which is also substantially higher compared to the results reported in 19,[21][22][23][24][25][26] . It is likely that the larger strain magnitudes are due to the larger VIF magnitudes as well as differences in simulating the contribution of muscle-tendon forces prior to and during landing.…”

“…The resulting peak relative AM-ACL strain spanned a wide range that could not be explained by differences in the applied VIF, e.g. 0.8% peak relative AM-ACL strain at a peak VIF of 2093N 26 versus 8.69% peak relative AM-ACL strain at a peak VIF of 1196N 19 . Contradictory results were also reported between the H:Q ratio during landing and the peak relative AM-ACL strain, with two studies reporting a positive correlation 20,21 and one study reporting a negative correlation 26 .…”

“…I). The most commonly applied cadaveric simulator was introduced by Withrow et al 18 , and used to analyse AM-ACL strain during jump landing in approximately 90 cadaveric specimens [18][19][20][21][22][23][24][25][26] . To replicate the passive muscle forces during jump landing, the quadriceps, hamstrings and gastrocnemius tendons were attached in series to aircraft cables with a known stiffness and pretension 18 .…”

“…Thus, the representation of the muscle stretch response to loading using nonlinear passive springs was considered valid. Later modifications to the initial design of the Withrow testing apparatus included the replacement of the aircraft cables with nonlinear springs to account for the muscle's bilinear elastic and viscous resistance to rapid stretch during dynamic movement 21,24 , as well as the consideration of the external hip rotator muscles, in addition to the quadriceps, hamstrings and gastrocnemius 19 .…”

SummaryBackground: The goal of this review is to summarise and discuss the reported influence of muscle-tendon forces on anterior cruciate ligament (ACL) loading during the jump-landing task by means of biomechanical analyses of the healthy knee. Methods: A systematic review of the literature was conducted using different combinations of the terms "knee", ''ligament'', ''load'', "tension ", "length", ''strain'', "elongation'' and ''lengthening''. 26 original articles (n=16 in vitro studies; n=10 in situ studies) were identified which complied with all inclusion/exclusion criteria. Results: No apparent trend was found between ACL loading and the ratio between hamstrings and quadriceps muscle-tendon forces prior to or during landing. Four in vitro studies reported reduced peak ACL strain if the quadriceps force was increased; while one in vitro study and one in situ study reported reduced ACL loading if the hamstrings force was increased. A meta-analysis of the reported results was not possible because of the heterogeneity of the confounding factors. Conclusion:The reported results suggest that increased hip flexion during landing may help in reducing ACL strain by lengthening the hamstrings, and thus increasing its passive resistance to

“…Recently, the mechanics of the hip, especially a restricted passive range of internal rotation at the hip, has been correlated with ACL injury and reinjury in soccer players [171,172]. Beaulieu et al [173] evaluated the impact of decreased internal femoral rotation on peak ACL strain during simulated singleleg pivot landing and found they were inversely related. A decelerating motion that develops a large tibial internal rotation torque result in particularly high-peak ACL strain [174].…”

ACL injury is one of the most frequent and costly injuries in sports, and is a major risk factor for early knee osteoarthritis. Although female gender is a major risk factor for ACL injury, differences in the injury mechanism between males and females have not yet been determined. The goal of this review was to determine whether there is any evidence of gender differences in the mechanisms of ACL injury. MRI studies demonstrated that the location of bone bruises after ACL injury was similar between genders and that males demonstrated more extensive damage in the joint, suggesting the involvement of higher energy but not a difference in injury mechanism. Video analyses of the process of ACL injury has shown common body positions at the time of injury, but failed to reveal differences in the joint motions between genders. Therefore, the mechanism of ACL injury is likely to be similar across genders.

The femoral enthesis of the human anterior cruciate ligament (ACL) is known to be more susceptible to injury than the tibial enthesis. To determine whether anatomic differences might help explain this difference, we quantified the microscopic appearance of both entheses in 15 unembalmed knee specimens using light microscopy, toluidine blue stain and image analysis. The amount of calcified fibrocartilage and uncalcified fibrocartilage, and the ligament entheseal attachment angle were then compared between the femoral and tibial entheses via linear mixed-effects models. The results showed marked differences in anatomy between the two entheses. The femoral enthesis exhibited a 3.9-fold more acute ligament attachment angle than the tibial enthesis (p < 0.001), a 43% greater calcified fibrocartilage tissue area (p < 0.001), and a 226% greater uncalcified fibrocartilage depth (p < 0.001), with the latter differences being particularly pronounced in the central region. We conclude that the ACL femoral enthesis has more fibrocartilage and a more acute ligament attachment angle than the tibial enthesis, which provides insight into why it is more vulnerable to failure.
