AB  - BACKGROUND: Patient satisfaction is increasingly used to measure the success of 
      arthroplasty. Satisfaction with the outcome of a total knee replacement (TKR) is 
      traditionally thought to be associated with improvements in functional status and 
      quality of life measures. This study aims to answer the following questions: 1. 
      What is the level of patient satisfaction, improvement in knee function and 
      patient quality of life associated with mechanically aligned TKR? 2. What is the 
      relationship between OKS, EQ-5d scores and 'outcome satisfaction'? HYPOTHESIS: 
      TKR is associated with a significant improvement in function, satisfaction and 
      quality of life and that there is a strong correlation between OKS, EQ-5d and 
      'outcome satisfaction'. METHOD: Five thousand eight hundred and ninety six 
      patients underwent primary TKR between January 2010 and December 2017 and had 
      complete preoperative and 2-year follow-up data for OKS, EQ-5d and satisfaction 
      scores. Outcomes data were collected prospectively and recorded on our 
      institutional database. Minimal clinically important difference (MCID) and the 
      Patient acceptable symptomatic state (PASS) were calculated for OKS and EQ-5d, 
      the association between OKS, EQ-5d and 'outcome satisfaction' was measured using 
      regression analysis. RESULTS: The median 2-year 'outcome satisfaction' score was 
      90/100 with 79% of patients reporting excellent satisfaction (>/=80/100) and 93.4% 
      of patients satisfied (>/=50/100). Postoperatively, median scores were 39 for OKS 
      and 0.8 for EQ-5d. The mean increase in scores was 15.85 for OKS and 0.32 for 
      EQ-5d. Satisfaction showed moderate positive correlation with postoperative OKS 
      (r=0.69) and EQ-5D (0.58) scores, but weaker correlation with the change in OKS 
      (r=0.57) and EQ-5d (r=0.32) scores from preoperative levels. 
      DISCUSSION/CONCLUSION: Mechanically aligned TKR is overall a successful operation 
      responsible of fair rate of patient satisfaction. OKS and EQ-5d are imperfect 
      predictors for satisfaction as they are significantly influenced by patients' 
      comorbidities. This should be taken into account when evaluating the success of 
      an operation. LEVEL OF EVIDENCE: IIc; observational study (based on prospectively 
      collected data from an institutional registry).
