• To establish recommendations for optimal suture use in surgical settings.

Main Methods:

• Utilized an Instron Tensile Tester for knot construction and performance analysis.
• Measured the number of throws to knot break.
• Assessed knot slippage and maximal holding force at knot break.

Main Results:

• Quantified the mechanical reliability of different knotted suture configurations.
• Identified critical parameters influencing knot security, including throws, slippage, and holding force.
• Established a data-driven basis for evaluating knotted suture performance.

Conclusions:

• Recommendations are provided for the appropriate use of specific sutures based on mechanical performance data.
• This analysis enhances understanding of knotted suture behavior under tensile load.
• The study offers valuable insights for surgeons selecting sutures for operative procedures.
