Dynamic Tendon Grip (DTG™) novel knot array compared to traditional sutures for zone two flexor tendon injury – a biomechanical feasibility study

Table 1 Biomechanical comparison of range of motion, gap formation and load to failure between DTG array and traditional flexor tendon suture

	Combined Range of motion (deg)		Gap formation (mm)	Load to Failure (N)
	Pre-operative	Post-operative
DTG suture array^a	244.0 ± 9.9	235.62 ± 9.4	0.31 ± 0.48	76.51 ± 23.15
Traditional flexor tendon suture^b	234.67 ± 6.51	211.67 ± 10.50	0	66.31 ± 40.22
