Nutritional and Physical Prehabilitation in Elective Orthopedic Surgery: Rationale and Proposal for Implementation.

Abstract

In the past, good food and exercise were not considered effective interventions to promote recovery in orthopedic surgery, and prolonged bed rest with not many calories has been deemed sufficient for the proper health restoration until the end of the nineteenth century. The advancement of scientific knowledge proved just the opposite, thus pushing health professionals to sustain the nutritional status and physical fitness of surgical patients. Nevertheless, the impoverishment of lifestyles and the lengthening of life expectancy have invariably contrasted the strength of constitution, giving rise to two of the most hazardous conditions for orthopedic patients: malnutrition and sarcopenia, often hiding nutrient deficits and poor body composition. These conditions are known to be negative prognostic factors in several areas of major surgery, including hip replacement, knee replacement, and spine surgery. Scoring systems to screen for malnutrition and physical inabilities exist, but disciplined management of the derived risks remains untested, potentially hindering the implementation of research findings into practice. A methodical approach of preoperative analysis, critical monitoring, and risk correction before surgery could lead to a substantial improvement of the prognosis while warranting the safety of patients and the efficiency of enhanced recovery after surgery pathways. The aim of this article is to discuss from a dietetic and exercise perspective the ideal nutritional and physical prehabilitation to lay the foundations for designing the appropriate integration of dietitians and physiotherapists in a preoperative enhanced recovery pathway. This methodical analysis could effectively calculate the patient’s risks, detect the best choices for resolving the risk, underline the ignored aspects of perioperative care, and represent a concrete means to integrate novel discoveries.
