1–year follow–up of 920 hip and knee arthroplasty patients after implementing fast–track

Figures & data

Figure 2. Pain at rest (upper panel) and mobilization (lower panel) at 8 time points, from preoperatively until 1 year postoperatively. Lines represent mean pain score for each patient group.

Table 2. Patient–reported outcome scores (PROMS) in the 4 different groups: EQ–5D, HOOS–PS, KOOS–PS, and the physical function scores HHS and KSS. For abbreviations, see text. All scores were obtained preoperatively, 8 and 12 weeks postoperatively, and 1 year postoperatively. Data are mean (SD)
