Short summary
This retrospective study analyzed 682 patients who underwent primary total hip or knee arthroplasty to evaluate the impact of malnutrition on post-operative outcomes. Malnutrition, as defined by the Nutritional Risk Screening 2002 (NRS-2002) and controlling nutritional status (CONUT) scores, was significantly associated with higher rates of post-operative infection and poorer quality-of-life scores. Early nutritional assessment may improve post-operative recovery and reduce complication rates.
