Preoperative Malnutrition Is Associated With Increased Rates of Periprosthetic Fractures in Total Knee Arthroplasty.

ABSTRACT:

Background

Periprosthetic fractures (PPFx) after total knee arthroplasty (TKA) are associated with high morbidity and mortality. While previous studies have shown the potential role of malnutrition as a predictor of PPFx in total hip arthroplasty, no studies have evaluated malnutrition as a risk factor for PPFx in TKA patients. This study aims to evaluate the relationship between preoperative nutrition status and PPFx after TKA.

Methods

We conducted a retrospective cohort study using data from the TriNetX Registry to identify patients who underwent primary TKA or revision TKA (rTKA) from 2005 to 2025. Preoperative nutrition status was assessed using albumin levels within 3 months prior to TKA based on prior arthroplasty and nutrition literature. Hypoalbuminemia was defined a
