Updates in Enhanced Recovery Pathways for Total Knee Arthroplasty.

Enhanced recovery after surgery (ERAS) programs for orthopedics involve a multidisciplinary approach to accelerating return to function, reducing pain, improving patient comfort and satisfaction, reducing complications from the surgical procedure, reducing hospital length of stay, and reducing costs. ERAS pathways for patients receiving total knee arthroplasty are different from those having intracavitary surgery; they are less focused on fluid homeostasis and gut motility than they are with optimizing systemic and local analgesics and providing a balance between the highest quality pain control and accelerated return to ambulation.
