3. The six tested knot configurations: a 3-throw square knot (A), a 4-throw square knot (B), a 1- throw surgeon’s knot with a 2-throw square knot (C), a 1-throw surgeon’s knot with a 3-throw square knot (D), a 5-throw square knot (E), and a TSOL knot (F).

5. Failure strength (Fig. 4-A) and stiffness (Fig. 4-B) with three different suture materials (braided polyblend [FW], polydioxanone [PDS], and polyester [Ethibond]) and three different knot configurations (8-throw square knot [Intact], TSOL knot, and 4-throw...
