Knot and Loop Security of High-Strength Suture Tape vs. High-Strength Suture Wire

To evaluate knot security, loop and size of suture tape wire. The single load to failure (LTF) cyclic loading one arthroscopic (Samsung Medical Center [SMC]) hand-tied (surgeon’s knot) using two tapes (Broadband-[BB], Suture Tape-[ST]) No. 2 wires (MaxBraid-[MB], FiberWire-[FW]). A third (FiberTape-[FT]), not commonly tied arthroscopically, was included in the group. Ten samples for each suture-knot combination were evaluated volume. Data compared with analysis variance Tukey post-hoc test considered significant at P < 0.05. In LTF testing, FT stronger than any other configuration. With surgeon’s knots, BB MB FW, while ST superior FW. loading, had less elongation Among smallest BB. largest among all configurations. No differences detected SMC-knot configurations LTF, elongation. Measuring FW greater volume ST, larger ST. Excluding FT, knots smaller SMC-knots. SMC-knots, bulkier MB. overall. best but poorest security better both wires; also bested Hand-tied BB, their counterparts. demonstrated knots; no seen between Thinner designs (BB, ST) wire when
