Background: This study was to investigate the characteristics and the basic data of two sizes of the JuggerKnot Mini 1.0 mm.
Methods: Twenty-three 3-0 and thirty-four 2-0 anchors were inserted into synthetic bone, and we used twenty 3-0 and 2-0 anchors each which had been inserted correctly on the first attempt. After a preload of 10 N, cyclic testing was performed at 10-30 N for 200 cycles, after which destructive testing was performed. The parameters included the insertion form, the failure mode, the load to failure, and elongation at rupture.
Findings: 3-0 suture was more likely to be completely inserted at first insertion compared with a 2-0 suture. The mean strength of each anchor was 73.0 N and 118.7 N for 3-0 and 2-0, respectively. The average elongation at rupture of the 3-0 and 2-0 anchors was 2.63 mm and 3.66 mm, respectively.
Conclusions: These basic data and characteristics should be taken into account when using the JuggerKnot mini 1.0 mm in a clinical setting.
