Outpatient unicompartimental knee arthroplasty 89 6 Discharge Prolonged hospital stay Complications/readmission 100%, <23hrs None N=1, developed a foot drop and a heel ulcer secondary to peroneal nerve dysfunction. N=1, revisions for a genu recurvatum deformity <10 N=1, tibial plateau fracture >1 YPO N=2, manipulation under anaesthesia to treat knee stiffness >3 and>6 MPO 85%, <11hrs N=2, high pain intensity N=1, fear to go home N=1, manipulation under anaesthesia to treat knee stiffness >6 WPO Finally, we recommend that further well designed randomized controlled trials with larger patient series will be needed to confirmour preliminary results. After this, health care organizations and hospital management will probally be convinced of the need of optimised clinical pathways. Conclusion Well-established and adequate protocols, standardized general applicable in- and exclusion criteria and a change inmindset for both the patient and themultidisciplinary team are the key factors for the successful implementation of an outpatient surgical pathway for unicompartimental knee arthroplasty.
