When deadman theory meets footprint decortication: a suture anchor biomechanical study

Table 1 Completed cycles, ultimate failure load, and failure modes in the different groups

Insertion angle	Completed cycles	Ultimate failure load (mean ± SD)	p value	Failure modes
Decorticated synthetic bone model
45°	10	67.5 ± 5.3 N	< 0.001*	10 anchor pullout
90°	20	114.1 ± 9.8 N	< 0.001*	10 anchor pullout
Non-decorticated synthetic bone model
45°	40	591.8 ± 58 N	0.003*	3 anchor pullout 2 suture rupture at eyelet 5 broken eyelet
90°	40	724.9 ± 94 N	0.003*	5 anchor pullout 5 suture rupture at eyelet

*Significantly different in ultimate failure load between two groups with the Mann-Whitney U test (p < 0.05)
