Osteoarthritis has a multifactorial etiology. It may be primary (idiopathic) or secondary to trauma, infiltrative disease, or connective tissue disease. Age, obesity, trauma, female gender, labour activities, heavy sports are the risk factors for OA. The risk of developing osteoarthritis increases with each decade after 45 years of age. 500 patients were diagnosed with knee OA (Osteoarthritis) were included in the study. The study includes all patients who underwent total knee arthroplasty, who have fulfilled the inclusion criteria. Preoperative long leg standing radiographs (Scannogram) by CR (computed Radiography) technique were taken for each patient. A statistically significant difference between the mean age of male and female patients when they opt to undergo total knee arthroplasty (P<0.05). Females were affected by osteoarthritis at a comparatively younger age than males.
