AB  - PURPOSE: The aims of this study are to evaluate whether improvements in 
      functional outcome and quality of life are sustainable 10 years after total knee 
      arthroplasty (TKA), and the age cut-off for clinical deterioration in outcomes 
      METHODS: Prospectively collected registry data of 120 consecutive patients who 
      underwent TKA at a tertiary hospital in 2006 was analysed. All patients were 
      assessed at 6 months, 2 years and 10 years using the Knee Society Function Score, 
      Knee Society Knee Score, Oxford Knee Score, Short-Form 36 Physical/Mental 
      Component Scores and postoperative satisfaction. One-way ANOVA was used to 
      compare continuous variables, while Chi-squared test to compare categorical 
      variables. Multivariate logistic regression and receiver operating curve analysis 
      was performed to evaluate the predictive factors associated with deterioration of 
      scores postoperatively. RESULTS: Significant improvements were noted in all 
      functional outcome and quality of life scores at 6 months after TKA. Between 
      6 months and 2 years, the KSFS and OKS continued to improve but the KSKS, PCS and 
      MCS plateaued. Between 2 and 10 years, there was a deterioration in the KSFS and 
      OKS, whilst KSKS, PCS and MCS were maintained. Increasing age was noted to be a 
      significant risk factor for deterioration of KSFS at 10 years with age >/= 68 as 
      the cut-off value. 91.7% of patients with KSFS Minimally Clinically Important 
      Difference(MCID) (>/= 7 points) continued to be satisfied after 10 years compared 
      to 100.0% who did not experience KSFS MCID deterioration (p = 0.02). CONCLUSION: 
      Patients >/= 68 years experience deterioration in functional outcomes and quality 
      of life from 2 to 10 years after TKA. LEVEL OF EVIDENCE: Retrospective study, 
      Level III.
