 Mean force is presented in Newtons. Actual difference is calculated by subtracting the force of the nonoperated leg from that of the operated leg. Relative difference is calculated by dividing the force of the operated leg by that of the nonoperated leg. SD standard deviation. pvalues from the paired Wilcoxon signedrank test
