A new microsurgical knot-tying technique, "through-the-loop," keeps the suture end secure, preventing tissue adhesion. This method simplifies knot tying for surgeons, especially novices, improving efficiency.

Area of Science:

Microsurgery
Surgical Techniques
Surgical Knot Tying

Background:

Microsurgical knot tying is critical for delicate procedures.
Traditional methods can be challenging due to suture end manipulation.
Suture end adherence to surrounding tissues complicates knot security.

Purpose of the Study:

To introduce and describe the 'through-the-loop' microsurgical knot-tying technique.
To highlight the advantages of this novel knot-tying method.
To assess the technique's utility for surgeons of varying dominance and experience levels.

Main Methods:

A novel 'through-the-loop' technique for microsurgical knot tying was developed.
The technique involves maintaining instrument control of the suture's short end throughout the process.

Applicability for both right- and left-hand-dominant surgeons was considered.

Main Results:

The 'through-the-loop' technique ensures the short suture end remains held by instruments.
This prevents accidental dropping and adhesion to surrounding tissues.
The technique facilitates easier re-grasping and more straightforward knot completion.

Conclusions:

The 'through-the-loop' technique offers a more secure and manageable approach to microsurgical knot tying.
It enhances efficiency and reduces difficulty, particularly beneficial for novice microsurgeons.
This method supports faster and more reliable knot construction in microsurgical procedures.
