Background: Mounting evidence supports the use of nutritional supplementation to improve patient outcomes. The intent of this study was to utilize an anonymous questionnaire to determine patients' baseline knowledge, attitude, and belief regarding nutrition before total hip (THA) or total knee arthroplasty (TKA).
Methods: After receiving Institutional Review Board approval, an anonymous questionnaire was administered to 300 patients, comprising 184 women (61.3%) and 116 men (38.6%), averaging 67 years (range, 39 to 89). There were 238 TKAs (79.3%), 12 revision TKAs (4%), 44 THAs (14.6%), and 6 revision THAs (2%).
Results: Almost all (99.6%) subjects recognized the importance of preoperative nutrition. Most (83.0%) claimed that they knew what to eat preoperatively to optimize their surgical outcomes and expressed high levels of self-reported confidence (98.6%). Women were more likely to report having knowledge of preoperative nutrition (P = .05), and advanced education levels were linked to higher confidence (P = .002). Only 169 (56.3%) subjects reported knowing what supplements to take. When asked, 84% of subjects stated that they would purchase a nutrition program if recommended by their surgeon. Most studies show that an improved diet and appropriate supplementation can optimize nutritional status and potentially improve surgical outcomes.
Conclusions: The results of this study confirm that most patients do not know how to achieve optimal nutrition. Therefore, we believe there is a need for patient education on preoperative nutrition and its benefits.
