Rationale: Obesity is a major risk factor for knee osteoarthritis, yet BMI alone may not fully reflect functional impairment before total knee replacement. This study aimed to evaluate the association of sarcopenia risk and nutritional intake with symptom severity in overweight and obese adults awaiting Total Knee Replacement surgery.

Methods: This cross-sectional study included adults aged ≥55 years with BMI ≥27 kg/m² awaiting total knee replacement. Nutritional status was assessed using the MNA-SF, dietary intake was evaluated using a food frequency questionnaire, and adherence to the Mediterranean diet was assessed by the PREDIMED score. Sarcopenia risk was evaluated using SARC-F, handgrip strength, and Timed Up and Go (TUG). Symptom severity and function were assessed using the WOMAC index. Associations were analyzed using Spearman correlations and group comparisons.

Results: A total of 52 participants (mean age ~69 years, 79% women) were included. Sarcopenia-related measures (SARC-F, low handgrip strength, and prolonged TUG) were significantly associated with higher WOMAC scores, indicating worse symptoms and function. Lower energy and protein intake were also associated with greater symptom severity. In contrast, BMI was not significantly associated with WOMAC outcomes.

Conclusion: Sarcopenia risk and low nutritional intake, rather than BMI, are associated with worse symptom severity in overweight and obese adults awaiting total knee replacement. These findings highlight the importance of comprehensive nutritional and functional assessment in the preoperative setting.
