AB  - BACKGROUND: This study was performed to determine if the effectiveness of 
      patellofemoral bracing as a treatment for patellofemoral osteoarthritis is 
      influenced by patellofemoral joint alignment and trochlear morphology. We 
      hypothesized that those with more extreme patellar malalignment would benefit 
      more from bracing. METHODS: Thirty-eight patients who had received bracing as 
      part of a comprehensive treatment plan for patellofemoral osteoarthritis were 
      selected for this study. Ten measures of patellar alignment were taken from 
      X-rays. These alignment measures were divided into percentile groups (tertiles) 
      for contingency table analysis. Treatment outcome was measured by Western Ontario 
      and Macmasters Universities Osteoarthritis Index (WOMAC) scores and these were 
      dichotomised into two groups according to "Improved" or "Not Improved" according 
      to the minimum clinically important difference (MCID). Spearman's rho test was 
      performed for continuous variables and Fisher's exact test was performed for 
      correlation between tertile groups and MCID categories. RESULTS: Thirty-eight 
      patients (9 male and 29 female) between the ages of 51 to 89 were included in 
      this study. WOMAC scores ranged from -25 to 41.67, with a mean change of -3.97, 
      31.6, 44.7 and 31.6% of patients falling into the "Improved" group for Global, 
      Pain and Function scores respectively. We found a non-significant trend shown 
      (p = 0.058, correlation coefficient 0.31) between bisect offset and change in 
      WOMAC global, indicating a trend for higher change in WOMAC scores with 
      increasing bisect offset. Statistically significant correlations were found 
      between mean MCID categories for the WOMAC global and function groups when 
      analysed against percentile groups for bisect offset (p < 0.01) and patellar 
      subluxation distance (p < 0.05), indicating those in higher percentile groups 
      were more likely not to improve after six months. CONCLUSION: Higher bisect 
      offset and patellar subluxation distance measures were associated with poorer 
      outcomes. However, due to the limited sample size, more studies are required to 
      fully examine this relationship.
