ABSTRACT

Background: Obesity is considered as significant independent risk factor for knee osteoarthritis. It is estimated that force of nearly 3 to 6 times one’s body weight is exerted across knee joint. Waist Hip Ratio is the good indicator of visceral fat, the waist hip ratio greater than 0.9 in females and greater than 0.8 in male’s increases excessive load on the knee joint which alters the Q-angle. The Western Ontario And McMaster Universities Osteoarthritis Index scale was used as an outcome measure to assess pain, stiffness, and physical function in patients with hip and knee osteoarthritis. Objective: To find out the early osteoarthritis knee in obese adults and effect of high hip waist ratio on Q-angle and its relation with osteoarthritis knee. Method: 50 subjects including male and female were included in this study with age between 35-45 years and classified into into 2 groups symptomatic and non-symptomatic Patients were clinically assessed for functional status by using Western Ontario And McMaster Universities Osteoarthritis Index scale. Result: The incidence of Osteoarthritis knee was found more in age group ranging from 41-45years and was greater in female population. The symptomatic patients were greater in obese class 2 and 3 with mean of 33.36±4.038. Q-angle was taken with mean deviation of 15.9±2.119 for male and 19.9±2.119 for female. Out of 30 symptomatic patients, 17 patients presented with WOMAC score between 20-40%.Conclusion: In this study, we concluded that incidence of osteoarthritis knee was found greater between age group 41-45years with female population more than male population.
