Other information
Malnutrition is a common and modifiable risk factor for postoperative complications and adverse outcomes in orthopaedics.

The purpose of this study was to identify biomarkers of malnutrition in patients undergoing elective total knee arthroplasty (TKA) that are predictive of adverse in-hospital postoperative complications, to facilitate the identification of at-risk patients for nutritional optimization before surgery.

Study Design & Methods
A total of 626 patients who underwent elective TKA between 2013 and 2017 were evaluated; potential biomarkers of preoperative malnutrition, including hypoalbuminemia (serum albumin <3.5g/dL), total lymphocyte count (TLC <1,500cells/mm3), and body mass index (BMI), were assessed for any association with in-hospital postoperative complications.

The prevalence of hypoalbuminemia, low TLC, overweight, obese class I, and obese class II were respectively 2.72%, 33.4%, 14.8%, 44.5%, and 26.9%. There was a significant association between obesity class II (BMI ≥30.0kg/m2) and rates of postoperative complications (p<0.001), and no significant association between such complications and hypoalbuminemia (p=0.539), low TLC (p=0.583), overweight (p=0.436), or obesity class I (p=0.749).

Obesity class II is a reliable biomarker of preoperative malnutrition for predicting in-hospital postoperative complications after elective TKA, whereas hypoalbuminemia, low TLC, overweight, and obesity class I was not significantly associated with increased risk of such complications.
