BACKGROUND: One-in-five patients are dissatisfied following knee arthroplasty and <50% have fulfilled expectations. The relationship between knee-arthroplasty expectations and surgical outcome remains unclear. PURPOSE: Are expectations regarding the impact of pain on postoperative life predictive of one-year outcome? Does the impact of pain on preoperative quality of life (QOL) influence this relationship? METHODS: Longitudinal cohort of 1044 uni-compartmental (43%) or total knee-arthroplasty (57%) (UKA or TKA) patients, aged mean 69 ± 9 years. Preoperatively, patients reported the impact of pain on QOL and expected impact of pain on life one-year post-arthroplasty. One-year postoperative outcomes: non-return to desired activity, surgical dissatisfaction, not achieving Oxford Knee Score minimal important change (OKS
