What is the typical extracorporeal knot length?

• A. 15 inches
• B. 60 cm
• C. 30 inches or 75 cm
• D. 10 inches

Answer: (C)

Extracorporeal knot length is the amount of suture left outside the patient when tying the knot outside the body. You need enough length to perform the throws, maintain tension, and maneuver the suture with your hands and instruments without losing control. The standard length used is about 30 inches, which is 75 cm. This provides ample material to complete secure throws and then slide the knot into the operative field smoothly. Shorter lengths, like 10–15 inches, would not give enough suture to tie a reliable knot, while 60 cm (about 24 inches) is shorter than the commonly taught standard.
