AB  - PURPOSE: Despite reduction in radiological outliers in previous randomized trials 
      comparing robotic-assisted versus conventional total knee arthroplasty (TKA), no 
      differences in short-term functional outcomes were observed. The aim of this 
      study was to determine whether there was improvement in functional outcomes and 
      quality-of-life (QoL) measures between robotic-assisted and conventional TKA. 
      METHODS: All 60 knees (31 robotic-assisted; 29 conventional) from a previous 
      randomized trial were available for analysis. Differences in range of motion, 
      Knee Society (KSS) knee and function scores, Oxford Knee scores (OKS), SF-36 
      subscale and summative (physical PCS/mental component scores MCS) were analysed. 
      In addition, patient satisfaction, fulfilment of expectations and the proportion 
      attaining a minimum clinically important difference (MCID) in KSS, OKS and SF-36 
      were studied. RESULTS: Both robotic-assisted and conventional TKA displayed 
      significant improvements in majority of the functional outcome scores at 2 years. 
      Despite having a higher rate of complications, the robotic-assisted group 
      displayed a trend towards higher scores in SF-36 QoL measures, with significant 
      differences in SF-36 vitality (p = 0.03), role emotional (p = 0.02) and a larger 
      proportion of patients achieving SF-36 vitality MCID (48.4 vs 13.8 %, p = 0.009). 
      No significant differences in KSS, OKS or satisfaction/expectation rates were 
      noted. CONCLUSION: Subtle improvements in patient QoL measures were observed in 
      robotic-assisted TKA when compared to conventional TKA. This finding suggests 
      that QoL measures may be more sensitive and clinically important than 
      surgeon-driven objective scores in detecting subtle functional improvements in 
      robotic-assisted TKA patients. LEVEL OF EVIDENCE: II.
