    Outpatient total hip and knee arthroplasty.
    Acta Orthop 2017 Dec 5:1-4. Epub 2017 Dec 5.
    d Section of Surgical Pathophysiology, Rigshospitalet , University of Copenhagen , Copenhagen , Denmark.
    As a result of the introduction of fast-track programs, the length of hospital stay after arthroplasty has decreased to a point where some patients meet the discharge criteria on the day of surgery. In several studies, well-established fast-track centers have demonstrated the feasibility of outpatient procedures in selected patients. However, in literature the term "outpatient" is sometimes also used for patients who spend one or more nights in hospital. Read More
