“…Despite several published studies having revealed the significant valgus moment at the knee joint during side-step cutting in females 2,4,7) , only a few studies have investigated the association between peak knee valgus moment and the posture of lower extremity joints 2,8) . McLean et al 2) found that a greater peak knee valgus moment was associated with larger initial hip flexion and internal rotation and with larger initial knee valgus angle during side-step cutting. Sigward and Powers 8) studied the loading characteristics of female athletes who exhibited excessive knee valgus moment during side-step cutting.…”

“…Based on reports that females produce significantly greater knee valgus moment than males during side-step cutting 2,4,7) , the second purpose of the current study was to further evaluate whether lower extremity joint posture associated with peak knee valgus moment was related to gender.…”

“…Joint angle at initial contact has been suggested to be the source of a subsequent peak knee valgus moment 2) . However, the angles of the hip, knee and ankle at peak knee valgus moment may also influence the magnitude of peak knee valgus moment.…”

“…Peak knee valgus moment is considered to be a risk factor predisposing athlete to anterior cruciate ligament (ACL) injury in non-contact episodes, especially females [1][2][3][4][5][6] . ACL injury is a common traumatic sport injury and is a potential cause of loss of sport participation, prolonged disability and heightened risk of osteoarthritic knee 1) .…”

Abstract. [Purpose] To determine the associations between peak knee valgus moment and lower extremity joint angles at initial contact and at peak knee valgus moment during side-step cutting and to investigate their associations with gender. [Subjects and Methods] Twenty healthy subjects and twenty basketball players participated in this study. Three-dimensional kinematics and kinetics of hip, knee and ankle joints were recorded during a side-step cutting protocol by six video cameras and a forceplate. Associations between peak knee valgus moment and three-dimensional hip, knee and ankle joint angles were analyzed using Pearson's product moment correlation.[Results] Peak knee valgus moment was significantly associated with increased hip flexion, knee flexion, ankle inversion and ankle external rotation at initial contact and at peak knee valgus moment. With regard to gender, significant associations between peak knee valgus moment and hip, knee and ankle joint angles were found only in females.[Conclusion] The results provided data on lower extremity joint posture related to peak knee valgus moment during side-step cutting and indicate that females are more sensitive to increased peak knee valgus moment while performing side-step cutting.

Anterior cruciate ligament injury (ACLi) reduces mechanical knee joint stability. Differences in muscle activation patterns are commonly identified between ACLi individuals and uninjured controls (CON); however, how and which of these differences are adaptations to protect the knee or adversely increase risk of joint instability remain unclear. Since the neuromuscular system integrates activity of all muscles crossing the knee to create a moment‐of‐force that opposes an external load, this study sought to quantify differences in individual muscle electromyography (EMG)–moment relationships between ACLi and CON. Participants isometrically modulated ground reaction forces during a standing force matching protocol to elicit combinations of sagittal, frontal and transverse plane moments. Partial least squares regressions determined which internal joint moment(s) predicted activation of 10 leg muscles for each group. Compared to CON, ACLi demonstrated greater contribution of rectus femoris to knee extension, semitendinosus and gastrocnemii to knee flexion, and lateral gastrocnemii to knee external rotation moments. ACLi also showed lower contributions of biceps femoris to knee flexion, medial gastrocnemius to internal rotation, and varied hip muscle contributions to frontal plane hip moments. Between group differences in EMG–moment relationships during static conditions suggest neuromuscular contributions to sagittal plane stability increases after ACL injury, while knee stability during knee abduction and external rotation is reduced. Clinical Significance: Clinical assessments of ACLi should account for deficits in frontal and rotational plane stability by including tasks that elicit such loads. Improving hamstring muscle balance, hip abductor and gastrocnemius function may benefit ACLi rehabilitation interventions and should be studied further. © 2018 Orthopaedic Research Society.
