Does Discharge Destination Matter after Total Knee Arthroplasty? A Single-Institution Korean Experience

PURPOSE: To compare extended care facility (ECF) and home as discharge destination after total knee arthroplasty (TKA) at a single high-volume tertiary center in South Korea. MATERIALS AND METHODS: We retrospectively analyzed 1,120 primary TKAs (614 patients) performed between January 2012 and December 2013. A telephonic survey was conducted to determine discharge destination. The data reviewed included demographic and surgical data, functional outcome at 2 years and complications within 3 months. RESULTS: ECF and home received 316 patients (51%) and 298 patients (49%), respectively. The ECF group had more bilateral TKA patients than the home group (272 vs. 234; p=0.014) and more patients with additional hospital stay (44 vs. 22; p=0.009). A higher tendency of complications was seen at home (n=8, 2.7%) than the ECF (n=2, 0.6%) (p=0.057). No significant differences were found in any functional outcome measure. Home patients had better patient satisfaction than ECF patients (81.9% vs. 54.3%; p<0.001). CONCLUSIONS: Patients who returned home after discharge had similar functional outcome at 2 years after surgery and higher patient satisfaction than those in the ECF in spite of the higher tendency of complications. Patients need adequate counseling and education regarding advantages and limitations of the two discharge destinations.
