Enhanced recovery pathways in orthopedic surgery

The enhanced recovery after surgery (ERAS)() concept, sometimes referred to as “fast track”, “accelerated,” or “Rapid Recovery” surgery, was first introduced in 1997. The concept of ERAS targets factors that delay postoperative recovery such as surgical stress and organ dysfunction. ERAS protocols or programs are a care package of evidence-based interventions used in a multimodal and coordinated clinical care pathway. They represent a multidisciplinary approach directed to reducing postoperative complications, shortening length of hospital stay, improving patient satisfaction, and accelerating recovery. ERAS was initially centered on abdominal and colorectal surgery patients; however, ERAS protocols have been widely extended to include other specialties. Orthopedic surgery, particularly elective hip and knee arthroplasty is one of such areas where ERAS principles have been adopted. It has been associated with reduced length of hospital stay, readmission rate, and improved functional recovery. The common interventions used in orthopedic ERAS programs have been divided into those performed in the preoperative, intraoperative, and postoperative phases of care. A PubMed literature search was performed for articles that included the terms enhanced recovery and orthopedic surgery. In this article, we summarized the clinical application of ERAS and highlighted the key elements that characterize an enhanced recovery program.
