Correlation between preoperative nutritional status and postoperative clinical outcomes in patients undergoing artificial hip and knee replacement

Key Points

Low preoperative nutritional index levels correlate with poor postoperative outcomes, indicating risk.
The nomogram model combining PNI, T2DM, disease duration effectively predicts clinical outcomes.

Structured PICO

Does a low preoperative PNI level increase the risk of poor outcomes in patients undergoing artificial hip and knee replacement?

Population

Patients undergoing artificial hip and knee replacement (THA/TKA)

Intervention

Preoperative nutritional status assessment (Prognostic Nutritional Index - PNI)

Outcome

Postoperative clinical outcomes (poor outcomes)

A nomogram incorporating preoperative nutritional status (PNI), T2DM, disease duration, and WOMAC score can help assess postoperative risk in patients undergoing hip and knee replacement.

Abstract

A low preoperative PNI level may increase the risk of poor outcomes in THA/TKA patients. The nomogram model incorporating PNI, T2DM, disease duration, and WOMAC score provides good reference for clinical assessment of postoperative risk.
