Fast-tracking for total knee replacement reduces use of institutional care without compromising quality

Figures & data

Figure 1. Median length of stay in days (LOS; left panel) and of uninterrupted institutional care (LUIC; right panel) in 2 2-year periods for primary total knee arthroplasty in 4 different hospitals. Hospital A was defined as a fast-track hospital after 2011.
