Background: Postural sway is very common in elderly population. It is mainly associated with balance. There are two factors, Decreased proprioception –which leads to sway when walking and increased reliance on vision. Vestibular weakness – as the person ages it’s common to have vestibular deficits which affects gaze stability and ability to turn head which affects balance. This may cause fall and increase the risk of injury. Objective: 1. To investigate the postural sway in elderly OA knee patients. To investigate the postural sway according to different grades of OA. Methodology: It was a cross-sectional study. Total 60 elderly individuals with OA knee were included using simple random sampling method. Result: The data was collected in OA Knee patients for sway in all four directions was analyzed with eyes open and eyes closed conditions. All 60 subjects having more sway in anterior and left lateral direction with both eyes open and eyes closed condition compared to their sway in posterior and right lateral direction. Conclusion: This study concludes that more sway was observed in anterior and left lateral direction both with eyes opened and eyes closed compared to posterior and right lateral direction in all Grade I, Grade II ,Grade III patients, all males and females, young old and middle old subjects. While in old old subjects the sway was found more in anterior and right lateral direction compared to posterior and left lateral direction.
