Introduction
The Two-Hand Tie is the fundamental technique in surgical knot tying and is considered the safest method for creating secure knots. It provides excellent control over knot direction, tension, and symmetry, making it the standard technique taught to surgical trainees. The uploaded reference emphasizes it as the most reliable method for achieving accurate and secure knots.
