A systematic review of 58 studies involving 2,076,289 patients found that nutritional disorders were associated with adverse outcomes after hip and knee arthroplasty.
2
Frailty was associated with higher mortality, more postoperative complications and infections, and longer hospital stays across arthroplasty populations.
3
ESPEN-defined malnutrition was associated with increased mortality, postoperative pain, and longer hospital stays.
4
Sarcopenia was associated with adverse outcomes, including prosthetic joint infection and poorer functional outcomes.
5
Associations varied by nutritional measure, and study heterogeneity and risk of bias prevented meta-analysis.
