Statistical methods / analysis
Changes in mean AOFAS scores before and after surgery will be analysed using paired t-test on GraphPad software. The level of significance will be set at p<0.05. Since no other study of this kind has been performed we can not calculate the appropriate sample size for this study. Based on out bio-statistician's recommendations we estimate that 100 patients will be sufficient to appropriately power our statistical analysis.
