Biomechanical Comparison of Banarji Knot with Various Sliding Locking Knots

Abstract

Abstract Background: The most essential part of arthroscopic shoulder surgery is tying a secure knot. A knot should be a low profile, nonbulky, and more stable construct. In the present research, we have compared the biomechanical performance of the new sliding locking knot-the Banarji knot, with two different sliding locking knots: The Samsung Medical Centre (SMC) Knot and the Weston Knot. Methods: Two samples of arthroscopic sliding locking knot, Banarji knot with three and five half hitches were taken. They were named Banarji Knots 1 and 2 in the study. The SMC Knot and Weston Knot were taken for comparison with the Banarji Knot. All knots were prepared with high-strength suture material fiber wire (Arthrex, Naples, FL, USA) and were tested in Bose Testing Machine to evaluate the load to failure of knots taken in the research. The statistical significance was determined using a P = 0.05. Results: The maximum load to failure was higher with the Banarji Knot, and it showed significantly better performance when compared with other knots taken in this study. The maximum load to failure in Banarji Knot 1 was 23% and 17% higher than SMC Knot and Weston groups, respectively, and that for Banarji Knot 2 was 29% and 22% higher than SMC and Weston groups, respectively. Conclusion: The Banarji knot is a low-profile, stronger, and stable knot. The biomechanical properties of the Banarji knot were better, and the load to failure was superior to SMC and Weston Knot.
