Quality of life after outpatient and fast-track hip and knee arthroplasty 157 10 Results 94 cases (26.1%) followed the outpatient surgery pathway (OS), while 267 patients (73.9%) followed the protocols of an enhanced recovery pathway (ERP). Baseline and operative data are presented in Table 2. 93 patients (99%) in the OS pathway were discharged on the day of surgery as scheduled, whereas in the ERP pathway 70%of the patients were discharged<3 days postoperatively. One patient in the OS pathway had prolonged hospital stay because not fulfilling the discharge criteria walking stairs. The first day postoperative the patient was discharged. At 12-month follow-up, the EQ-5D (both index and VAS), the OKS, WOMAC and NRS-pain score improved significantly (p<0.000) within each pathway. There were no significant differences between both pathways. Outcome measures data are summarized in Table 3. Table 2. Baseline and operative data presented as mean (±SD) or absolute numbers for both groups.
