Variations in varus/valgus and internal/external rotational knee laxity and stiffness across the menstrual cycle.
Cyclic variations in genu recurvatum (GR), general joint laxity (GJL), varus-valgus (VV), and internal-external (IER) rotational laxities and stiffnesses were examined in 64 females and 43 males at two time points during the females' menstrual cycle [days of minimum (T1) and maximum (T2) anterior knee laxity (AKL)]. Cyclic increases in AKL (9.5%), GR (37.5%), and GJL (13.6%) were observed in fe...
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 کاملKnee Laxity Variations in the Menstrual Cycle in Female Athletes Referred to the Orthopedic Clinic
BACKGROUND Anterior cruciate ligament (ACL) rupture is the biggest concern for orthopedic surgeons who are involved in sports injuries, so most of ACL reconstruction surgeries are sports related. ACL injuries in female athletes are 2 - 8 times more common than male athletes in similar sport injuries. OBJECTIVES The aim of this study was to compare knee laxity changes in the menstrual cycle in...
متن کاملRelationship between sex hormones and anterior knee laxity across the menstrual cycle.
PURPOSE To comprehensively quantify through daily, serial measures changes in knee laxity as a function of changing sex-hormone levels across one complete menstrual cycle. METHODS Twenty-five females, 18 - 30 yr, body mass index < or = 30, who reported normal menstrual cycles (28-32 d) over the past 6 months participated. Participants were tested daily across one complete menstrual cycle; 5-7...
متن کاملRelationship between knee joint laxity and knee joint mechanics during the menstrual cycle.
BACKGROUND An increase in knee laxity during the menstrual cycle may increase the risk of anterior cruciate ligament injury. OBJECTIVE To investigate whether changing knee laxity during the menstrual cycle correlates with changing knee joint loads in a cutting manoeuvre. DESIGN Cross-sectional study. SETTING Laboratory testing. PARTICIPANTS 25 healthy women, with a normal menstrual cycl...
