“…In the present study, we used the flexor/extensor (FLX/EXT) ratio as an assessment parameter, because it is an indicator of normality with regard to the balance between the function of the extensors and flexors of the knee. There is a 50-70% oscillation in the flexor/extensor ratio of the healthy knee joint (12,16,17,18,19).…”

Introduction The incidence of knee injuries is very high in young adults. Anterior cruciate ligament (ACL) rupture is the most frequent of them. The isokinetic dynamometry evaluation determines the functional patterns of strength and muscle balance.Objective To compare the isokinetic hamstring/quadriceps peak torque and work ratios of young adults after surgical reconstruction of the anterior cruciate ligament.Methods We selected 33 medical records filed by the Isokinetic laboratory of the Physiotherapy Clinic of the Catholic University of Paraná (PUCPR), which belonged to patients who had undergone isokinetic assessment at the request of a physiotherapist or physician in Curitiba, Paraná. The tabulated data were: Hamstring/Quadriceps peak torque and work ratios of all injured and non-injured limbs at an angular velocity of 60°/s. Data were processed by the statistical software LHstat. Inferential statistics was used in order to apply the comparison test between means (unpaired t-test) with a confidence interval of 95%.Results The average flexion-extension ratio of the non-involved limb was lower than the involved limb both for peak torque (peak torque ratio of the non-involved limb: 56.1%; peak torque ratio of the involved limb: 66.3%; difference: 10.2%) and work (work ratio of the non-involved limb: 60.1%; work ratio of involved limb: 66.1%; difference: 6%).Conclusion : The average flexion/extension ratio found was adequate for both limbs and variables, however, the subjects presented a greater number of muscle asymmetries in the involved limb than in the non-involved limb.

“…They suggested that increased knee joint laxity during menstrual cycle leads to greater knee joint loads in selected high risk movements in healthy young females ). Although, some researchers said knee joint laxity may not explain the higher incidence of females' ACL injury, they suggested that muscle strength and dynamic stability are more important (Bowerman et al, 2006). Some others measured knee JPS with isokinetic dynamometer in sitting position with high skin stimulations and suggested passive joint position sense and joint laxity don't change across the menstrual cycle (Hertel et al, 2006).…”

“…For muscular capacity, 11 studies have looked into its association with sustaining a non-contact ACL injury (Ahmad, et al, 2006;Bee-Oh, et al, 2009;Bowerman, Smith, Carlson, & King, 2006;Grygorowicz, Kubacki, Pilis, Gieremek, & Rzepka, 2010;Hiemstra, Webber, MacDonald, & Kriellaars, 2007;Holcomb, Rubley, Lee, & Guadagnoli, 2007;Hosokawa, et al, 2011;Mattacola, et al, 2002;Roberts, Ageberg, Andersson, & Fridén, 2007;Wilkerson, et al, 2004;. These studies have associated muscular capacity with risks of acquiring ACL injury, validating ACL screening tools to be used in intervention programs to prevent ACL injury.…”
