The objective of the study was to evaluate co-relation between fall risk, kinesiophobia, and physical- activity level among elderly females after one year of TKA. Methodology: This study was a cross-sectional survey conducted on females who had their Total Knee arthroplasty from Ghurki Trust & Teaching Hospital and Punjab Medical Centre, Lahore. Data was collected from 200 (n) elderly females who had undergone their Total Knee Arthroplasty at least one year before the study was conducted. Fall risk (Berg Balance Scale), fear of movement (Tampa Scale of Kinesiophobia), and physical activity (IPAQ) were the key outcome measures. Results: Pearson correlation determined higher levels of association between fall risk, fear of movement and physical activity. Higher the berg balance score, lower the score of Kinesiophobia i.e. negatively significant correlation; r (198) = -.54, p=0.00. Higher berg balance scores were also found to be positively related to higher minutes of low, moderate and vigorous exercise per week. Kinesiophobia was found to be negatively significant for physical activity of low, moderate and vigorous intensity i.e. r (198) = -.11, p= .01, r (198) = -.03, p=.00 and r (198) = -.07, p= .02 respectively. Conclusion: A significant negative correlation was observed between fall risk and Kinesiophobia. Moreover, a significant positive correlation was observed between fall risk and physical activity in elderly females who have had TKA
