Table 7. Return to sport and additional procedures after ACL reconstruction compared between the femoral tunnel drilling techniques.
The chi-square test of homogeneity with the post-hoc test (z-test of two proportions) found no significant differences for pairwise comparison when analyzing the above outcome measures.
