Background : Since the osteoarthritis (OA) mainly knee joint (OA) remains a major concern in term of cost, work loss, and life disturbing dilemma in the world as a whole. Therefore, in Egypt knee (OA) is one of the public health challenges that put a large social and economic burden as well as affected individuals. It was therefore speculated that hip muscle weakness could play a role in knee injuries. Many studies included the hip abductors but still little studies that include hip adductors. OBJECTIVES: The purpose of this study was to investigate if there is a relationship between the isokinetic strength for each of hip abductor peak torque, and hip adductor peak torque with the clinical manifestation of knee (OA) (pain, stiffness, functional disability) in women. METHODS: Forty women patients participated in this study represented with mean age (52.1) years, mean weight (89.5) (Kg), mean height (159.9) (Cm) and mean BMI (35.1) (Kg/m2).diagnosed as knee (OA) with different grades (according to Kellgren and Lawrence criteria). The concentric hip abductors and adductors were assessed using a Biodex Isokinetic Dyna- mometer, Multi-Joint System 3, at a speed of 90{u00B0}/s. Self-reported symptoms and disability were assessed using the WOMAC questionnaire. This questionnaire was translated and validated for Arabic language. RESULTS: The results of this study demonstrated that there was significant moderate negative correlation between the concentric hip abductors and abductor peak torque and pain (r=-0.339 p=0.033)and (r=-0.337 p=0.031) respectively. Also there was strong significant negative correlation between hip abductors torque and physical function (r=-0.420 p=0.007)
