AB  - PURPOSE: To compare patient-reported outcomes measures, health-related quality of 
      life and satisfaction rates between a new Modern TKA system (M-TKA) and an 
      existing Traditional TKA system (T-TKA). METHODS: Prospectively collected 
      registry data of 65 patients who underwent T-TKA and 65 patients who underwent 
      M-TKA at a single institution from 2014 to 2015 was reviewed. The range of 
      motion, Knee Society Knee Score (KSKS), Function Score (KSFS), Oxford Knee Score 
      (OKS), SF-36, satisfaction and expectation fulfilment were compared at Pre-op, 
      6 months and 2 years. Patellofemoral joint-related OKS subscores (3, 5, 7, 12) 
      were also compared between the groups. Minimal clinically important difference 
      (MCID) in OKS/SF-36 were analysed for both groups. Propensity scores generated 
      using logistic regression were used to adjust for confounding variables, thus 
      allowing matching of T-TKA to M-TKA in a 1:1 ratio. RESULTS: Both groups showed a 
      significant improvement in all measured variables at 6 month and 2 years 
      (p < 0.001) when compared to baseline. There was no significant difference in 
      KSKS, KSFS, OKS, SF-36 and Patellofemoral joint-related OKS subscores (3, 5, 7, 
      12) between the two groups (n.s.). At 2 years, there were high satisfaction rates 
      of 89.2% and 92.2% in the T-TKA and M-TKA groups, respectively (n.s.). Similarly, 
      both groups demonstrated high expectation fulfilment rates of 84.6% and 90.6% for 
      the T-TKA and M-TKA groups, respectively (n.s.). CONCLUSION: Using an extensive 
      battery of standardized patient-reported, health-related quality of life and MCID 
      assessments, our study demonstrated no difference in clinical outcomes between 
      M-TKA and T-TKA that would justify the use of the newer and costlier M-TKA. 
      Longer follow-up is necessary to evaluate the possible advantages of this new 
      implant design. LEVEL OF EVIDENCE: Level III, Retrospective Study.
