Cyclic variations in multiplanar knee laxity influence landing biomechanics.
PURPOSE Females vary substantially in their multiplanar cyclic knee laxity changes across the menstrual cycle. The biomechanical implications of these cyclic changes are relatively unknown. Our purpose was to first cluster females based on their cyclic changes in anterior knee laxity (AKL), genu recurvatum (GR), varus-valgus (VV), and internal-external (IER) rotation knee laxity across the mens...
متن کاملIdentifying multiplanar knee laxity profiles and associated physical characteristics.
CONTEXT A single measure of knee laxity (ie, measurement of laxity in a single plane of motion) is probably inadequate to fully describe how knee joint laxity is associated with anterior cruciate ligament injury. OBJECTIVE To characterize interparticipant differences in the absolute and relative magnitudes of multiplanar knee laxity (ie, sagittal, frontal, and transverse planes) and examine p...
متن کاملA comparison of cyclic variations in anterior knee laxity, genu recurvatum, and general joint laxity across the menstrual cycle.
Changes in anterior knee laxity (AKL), genu recurvatum (GR) and general joint laxity (GJL) were quantified across days of the early follicular and early luteal phases of the menstrual cycle in 66 females, and the similarity in their pattern of cyclic variations examined. Laxity was measured on each of the first 6 days of menses (M1-M6) and the first 8 days following ovulation (L1-L8) over two c...
متن کاملInfluence of relative hip and knee extensor muscle strength on landing biomechanics.
PURPOSE This study aimed to determine whether the tendency of women to exhibit higher knee extensor moments relative to hip extensor moments during the deceleration phase of landing can be explained by the relative strength of the knee and hip extensors. METHODS Forty recreationally active individuals participated in this study (20 men and 20 women). The maximum isometric strength of the knee...
متن کاملKnee joint laxity and its cyclic variation influence tibiofemoral motion during weight acceptance.
PURPOSE to better understand how sex differences in anterior knee laxity (AKL) affect knee joint biomechanics, we examined the consequence of greater absolute baseline (males and females) and cyclic increases in AKL during the menstrual cycle (females) on anterior tibial translation (ATT) as the knee transitioned from non-weight-bearing to weight-bearing conditions, while also controlling for g...
