Abstract
OBJECTIVE: We evaluated the loop and knot security of a novel arthroscopic knot, the Wiese knot, using different types of sutures. METHODS: The Wiese knot was tied using four different brands of braided sutures (Ethibond, Orthocord, FiberWire, and UltraBraid) with and without a series of three reversing half-hitches (RHAPs) and tested for loop and knot security. RESULTS: Orthocord provided the greatest amount of loop security. FiberWire delivered the highest knot security. UltraBraid had the greatest ultimate force. Three half-hitches increased the maximal load to clinical failure. CONCLUSION: The biomechanical characteristics of the Wiese knot are affected by suture material qualities.
