Table 6. Post-hoc test for the pairwise comparison of patient improvement in satisfaction from pre-surgery to post-surgery for the results in Table 5.

The significance seen between the three femoral drilling techniques (noted in Table 5) was due to the significant difference found between transtibial (TT) and anterior medial portal rigid reaming (AMP-RR) techniques. Bonferonni correction was applied to all p-values to reduce the risk of making a Type 1 error.

	Techniques compared	Significant difference	p-value
Δ IKDC Question 4: During the past four weeks, or since your injury, how stiff or swollen was your knee?	TT vs. AMP-RR	None	0.423
