Malnutrition and Total Joint Arthroplasty.

Malnutrition is prevalent in patients undergoing elective total joint arthroplasty (TJA). Malnutrition has been shown to be an independent risk factor for multiple postsurgical complications following TJA in addition to increasing postoperative mortality. In the current healthcare environment, it is important to recognize and correct modifiable risk factors preoperatively to minimize perioperative complications and improve patient outcomes. Recently, multiple studies have been published focusing on the association between malnutrition and perioperative complications following TJA. The findings of these studies are summarized in this review. Further research is required to determine if optimization of nutritional status preoperatively influence surgical outcomes in the elective TJA patient.
