The mean PROM values preoperatively, 3 months and 1 year postoperatively and the mean individual change according to age groups. PROM values range from 0 (no problem) to 100 (worst problem imaginable) * The mean individual improvement in PROM from preoperatively to 1 year postoperatively is presented for patients with responses at both occasion
