“…A recent cadaveric study demonstrated agreement with the proposed injury mechanism reported from ‘in vivo’ studies; increased knee valgus and anterior tibial translation (and to a lesser extent internal tibial rotation) increase ACL strain 9. Finally, biomechanical laboratory studies have contributed to the current understanding of ACL injury factors as described in a recent literature review of the past 20 years 21. In addition to the prospective coupled biomechanical-epidemiological study discussed above,10 studies have compared the biomechanics of athletes at high risk for ACL injury to those at low risk finding that female athletes, compared to males, perform athletic tasks with patterns consistent with the ligament dominance theory 22…”

Abstract.[Purpose] The purpose of this study was to compare the strength and endurance between open and closed kinematic chain exercises after anterior cruciate ligament reconstruction.[Subjects] Sixty-two subjects actively participating in rehabilitation for anterior cruciate ligament reconstruction for the last 3 month were chosen. Twenty-six subjects were excluded and consequently, the data of 36 subjects were analyzed. The participants were randomly divided into 2 groups for open or closed kinematic chain exercise. [Methods] Open or closed kinematic chain exercises were performed under direct supervision of 3 physical therapists for 30 minutes per session, 3 times a week for 12 weeks. Before and after the intervention, isokinetic strength, endurance, and squat strength were tested. [Results] In the comparison of the before and after exercise results, all variables showed significant differences. Open kinematic chain exercises resulted in a significantly greater gain in isokinetic strength and endurance of the extensor muscles than the closed kinematic chain exercises. [Conclusion] Open kinematic chain exercise is helpful for the development of strength and endurance of the knee extensor mechanism after anterior cruciate ligament reconstruction, and can be used effectively in a rehabilitation program.

“…In particular, Kazemi et al 6 provided a general review of computational models to analyse the mechanical function of the knee joint during different loading conditions; Pappas et al 7 summarised available techniques to measure ligament strain and forces in vivo with an emphasis on their advantages, limitations, and clinical relevance; and Bates et al 4 provided a summary of the literature on the biomechanical evidence regarding ACL loading during physiological or clinical tasks from in vitro cadaveric simulations. The latter group further conducted a meta-analysis of the reported ACL forces during passive knee flexion, in which a strong correlation was found between anterior-tibial translation and ACL ligament forces during passive knee flexion 4 .…”

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
