BACKGROUND: Static and dynamic balance impairment is seen in multiple cases of knee osteoarthritis (OA). The affection of body perception has also been observed. Balance and body perception are an integral part while performing daily activities. The affection of these further leads to fear of fall. The aim of this study was to find the relation between balance and knee body perception in primary OA knee patients. METHODS: This was a correlational study. Seventy-three patients with primary knee OA were recruited from tertiary care hospitals. Kellgren–Lawrence Grading system (I-IV) was used to assess the severity of knee OA. Patients having pain on the Visual Analog Scale 6/10 or below were included. The Fremantle Knee Awareness Questionnaire was used to assess a patient's body perception about the osteoarthritic knee. Static balance was assessed using four-stage balance test. Dynamic balance was assessed using the Timed Up and Go test. RESULTS: Statistical analysis was performed using Spearman's Correlational test to investigate the correlation between balance performance and knee body perception. The study included 73 patients within 45–80 years (59.4 ± 9.0). An overall strong positive correlation was obtained between balance performance and knee perception (r = 0.76, P = 0.00). Based on the OA grades, this correlation was moderate (r = 0.62, P = 0.00) in mild OA, moderate (r = 0.47, P = 0.05) in moderate OA, and strong (r = 0.71, P = 0.02) in severe OA. CONCLUSION: In knee OA patients, positive correlation exists between balance performance and knee body perception. As the severity of the disease increases, there is more impairment in balance and body perception. This affects the physical performance, quality of life in knee OA patients.
