Overview
The purpose of this study is to determine the effect on hematological markers of nutritional intervention on nutritionally deficient patients following total joint replacement surgery.
Description
Numerous pre-operative modifiable variables have been extensively investigated for their effect on outcomes in TJA. These include metabolic diseases such as diabetes mellitus, obesity, and smoking status. However, nutritional status has not been as thoroughly investigated; to date, no prospective randomized control study has assessed the effect of oral nutritional supplementation for malnourished patients. This study will be a novel investigation into the role for routine serum screening for malnutrition as well as oral nutritional supplementation in TJA patients. This study could serve as a stepping stone towards creating a new pathway to highlight at-risk patients and pre-operatively optimizing their outcomes after TJA.
