Abstract Background: Obesity is a well-established risk factor for knee osteoarthritis (OA). Although findings are somewhat inconsistent, many studies report a strong association between increased body weight and degenerative changes in the knee. Assessment of body composition may offer additional insights beyond body mass index (BMI) alone. Aims and Objectives: This study aimed to evaluate the association between body composition parameters and radiographic knee osteoarthritic changes in males aged 40–50 years with a BMI of 18.5–29.9 kg/m 2 , using bioelectrical impedance analysis (BIA). Materials and Methods: Eighty male participants underwent bilateral knee radiography and body composition assessment using BIA. Radiographic severity of OA was graded according to the Kellgren–Lawrence classification system. Correlation analysis was conducted between OA grade and BMI, body fat percentage, fat-free mass, skeletal (bone) mass, and muscle mass. Results: No significant correlation was found between radiographic OA grade and BMI or body fat percentage ( r = –0.001 and 0.073, respectively). Mild, nonsignificant negative correlations were observed between OA grade and fat-free mass, skeletal mass, and muscle mass ( r = –0.092, –0.125, and –0.083, respectively). Conclusion: Among males aged 40–50 years with a BMI of 18.5–29.9 kg/m 2 , body composition parameters, including BMI, body fat percentage, and lean mass components, were not significantly associated with radiographic knee OA.
