Geriatric Nutritional Risk Index is a risk factor for long-term decreases in patient-reported outcome measures following total knee arthroplasty.

ABSTRACT:

Purpose

Total knee arthroplasty (TKA) is an effective treatment for alleviating pain and improving function in patients with end-stage knee osteoarthritis. However, factors influencing long-term patient-reported outcome measures (PROMs) remain underexplored. This study aimed to evaluate the relationship between preoperative nutritional status, specifically the Geriatric Nutritional Risk Index (GNRI), and the long-term decline in PROMs following TKA.

Methods

We conducted a retrospective cohort study including patients who underwent TKA between 2000 and 2009. PROMs were assessed using the Knee Society Score (KSS) at two time points: an initial evaluation in 2012 (median postoperative 4 years) and a follow-up in 2023 (median 13 years). Preoperative GNRI, body mass index (BMI),
