Background and Purpose: Decreased muscle strength, proprioception, balance and mobility in patients with osteoarthritis (OA) give rise to loss of self-efficacy and self-confidence reducing the functional ability to perform activities of daily living thereby contributing to fear of fall. The purpose of the study was to find the association of fear of fall with functional strength, endurance and balance in patients with osteoarthritic knee. Methodology: 50 patients with OA knee were included in present cross-sectional study. Participants were assessed for strength using Stair Climb Test (SCT), balance using 5 times sit-to-stand (5T-STS), endurance using 2 Minute Walk Test (2 MWT) and fear of fall using Fall Efficacy Scale-International (FES-I). Data analysis was done using SPSS software and correlations between fear of fall and functional strength, endurance and balance were obtained using Pearson’s correlation coefficient. Results: There was moderate positive correlation (r = 0.41) between SCT and FES-I, no correlation (r = 0.005) between 5 T-STS and FES-I and weak negative correlation (r = -0.18) between 2 MWT and FES-I in patients with osteoarthritic knee. Conclusion: The study concluded that there were moderate positive, weak negative and no correlation exists of fear of fall with functional strength, endurance and balance respectively in patients with osteoarthritic knee.
