How is the square knot recommended to be performed?

The square knot is an essential knot used in surgical procedures, particularly for securing sutures. Performing the square knot as a two-handed tie is the recommended technique because it allows for better control and accuracy in the knot's formation.

Using both hands enables the assistant to create consistent tension and maintain the integrity of the knot, ensuring that it holds securely without slipping. The two-handed approach is essential for creating a reliable and precise square knot, which is crucial in surgical settings to minimize the risk of complications or suture failure.

In contrast, using a single-handed tie may compromise the knot's security and precision, while sliding knots and locking techniques are different knot types with specific applications that may not be suitable for every suturing need.
