Outpatient surgery and early discharge is the hottest topic in hip and knee arthroplasty and will continue to be in the coming years: It is expected that over 50% of all hip and knee arthroplasties will be performed in the outpatient setting by 2026. Currently, a central text that encompasses all of the unique aspects of performing hip and knee arthroplasty in the outpatient setting does not exist. Furthermore, as surgeons across the US and abroad are incentivized and encouraged by government and commercial payors, as well as patients, to perform these surgical procedures in the outpatient setting, the educational material must be available to disseminate the unique perioperative and surgical strategies and techniques accordingly.
