The Effect of Perioperative Nutritional Care on Recovery After Knee and Hip Replacement Surgery

This prospective observational study will assess the impact of standardized perioperative nutritional care on postoperative outcomes in patients undergoing elective total hip (THA) or knee arthroplasty (TKA) at the First Department of Orthopaedic Surgery, St. Anne's University Hospital in Brno. The protocol includes preoperative patient education, nutritional risk screening, and carbohydrate loading up to two hours before anesthesia, followed by early postoperative refeeding.

Data collection will include demographic and surgical variables, nutritional status, carbohydrate intake, and the occurrence of intra- and postoperative complications, including infection and delayed wound healing.

As perioperative nutritional care is part of routine clinical practice, the study requires no additional interventions or resources. Results will provide evidence on the effectiveness of structured nutritional support in enhancing recovery and reducing complications after joint replacement surgery.
