Name a common knot-tying pattern used in intracorporeal suturing?

• A. Square knot.
• B. Slip knot.
• C. Granny knot.
• D. Bow knot.

Answer: (A)

When tying sutures inside the body, you want a knot that is secure, reliable, and sits neatly against the tissue so it doesn’t irritate or bulk up the closure. The square knot fits that need well. It’s formed by two opposite-direction throws, creating a symmetrical, locking pattern that holds tension evenly and resists slipping. This makes it dependable under the forces you apply during intracorporeal suturing with long instruments, where tactile feedback is limited and knots must hold in a confined space. The knot also tends to lie flat, which helps with tissue approximation and healing.

Other patterns don’t provide the same combination of security and practicality in this setting. A slip knot is prone to changing tension and loosening; a granny knot is less stable and more likely to loosen if formed imperfectly; a bow knot isn’t a standard, reliable choice for surgical tissue closure and can create bulk. So the common knot used in intracorporeal suturing is the square knot.
