Effects of Preoperative Whey Protein and Exercise Support on Recovery After Total Hip Arthroplasty

Objective: The aim of this project is to evaluate the effects of preoperative whey protein supplementation and a physical exercise program on postoperative recovery outcomes in patients undergoing total hip arthroplasty (THA). Specifically, inflammatory markers (CRP), nutritional status (albumin), mobilization time, length of hospital stay, and physical and social functioning will be assessed. As one of the first randomized controlled trials in Turkey to focus on the preoperative period and to evaluate a combined nutrition and exercise intervention in elderly surgical patients, this study holds pioneering significance in both clinical and academic contexts. Methods: This study is designed as a randomized controlled trial. The intervention group will receive whey protein supplementation and a home-based exercise program for 14 days preoperatively, while the control group will receive standard preoperative care. Data collection will be performed preoperatively and on postoperative days 3 and 5, focusing on metabolic and functional parameters. Expected Outcomes: The findings of this study are expected to contribute to the improvement of patient care through a multidisciplinary approach, inform health policy development, and provide a foundation for larger-scale clinical research in Turkey.
