[Treatment of malnutrition in total joint arthroplasty : Consensus statement of the Perioperative Management Committee of the German Society for Endoprosthetics].

Pre- and perioperative management of malnutrition is crucial for the success of hip and knee arthroplasties. Various studies indicate that malnutrition, particularly when associated with vitamin D deficiency, significantly increases the risk of postoperative complications such as periprosthetic fractures and infections, prolonged hospital stays, and higher mortality rates. Adequate preoperative nutritional intake, including vitamin D supplementation, can improve arthroplasty outcomes. Current literature emphasizes the importance of comprehensive nutritional optimization before surgery to minimize the risk of complications and promote recovery.
