Chapter 10 154 Abstract Purpose Enhanced recovery pathways after knee arthroplasty have been introduced worldwide with positive results. The present study investigated the improvements of health-related quality of life and functional outcome in patients operated for knee arthroplasty who followed an Outpatient Surgery (OS) or Enhanced Recovery (ER) pathway. Methods We reviewed our institutional database of 361 consecutive patients undergoing knee arthroplasty (total and partial) who followed either the OS-pathway (n=94; 26.1%) or ER-pathway (n=267; 73.9%). Recordedoutcomes included4different patient reported outcome measures (PROMs; EuroQol-5D (both index and VAS), Oxford Knee Score, Western Ontario and McMaster Universities Arthritis Index and the Pain-Numerical Rating Scale) obtained pre-and during the 3-and 12-months postoperative follow-up. Results 93 patients (99%) in the OS-group were discharged on the day of surgery as scheduled, whereas in the ER-group 70% of the patients were discharged<3 days postoperatively. At 12-month follow-up, the EQ-5D (both index and VAS) and other PROMs improved significantly (p<0.000) within each pathway. Therewere no significant differences between both pathways. Conclusion Oneyear after knee arthroplasty, patientswhowere included inanOutpatient Surgery pathway had comparable quality of life and PROMs as patients operated in an Enhanced Recovery pathway.
