The square knot is traditionally used. First, the tip of the needle holder is rotated clockwise around the long end of the suture for two complete turns (see the image below).
What kind of knot do surgeons use?
[1–2] Flat square knots are the gold standard for surgical procedures because they are more secure when there is a risk of tearing a suture through delicate tissue.
What is the most common knot in suturing?
The two-hand square knot is the easiest and most reliable for tying most suture materials. It may be used to tie surgical gut, virgin silk, surgical cotton, and surgical stainless steel.
What type of stitch do doctors use?
A doctor uses a piece of surgical thread called a suture to sew (or stitch) two ends of skin together. Surgeons once used animal tendons, horsehair, pieces of plants, or human hair to create sutures. Today, they’re made from natural or manmade materials like plastic, nylon, or silk.
What is the difference between a square knot and a surgeon’s knot?
The surgeon’s knot differs from the square knot due to an extra pass through the loop of the first throw. This extra twist in the first throw provides more friction to maintain its position until the second throw is placed.
How strong is a surgeon knot?
Secondly, the Surgeons Knot is strong and estimated to be up to 100 percent strength as if it were a continuous line. This is a knot that can be used to join different materials whether equal or unequal in diameter but with the strength as if it was one piece without separate ends.
What is the difference between a square knot and a granny knot?
The granny knot is a binding knot, used to secure a rope or line around an object. It is considered inferior to the reef knot (square knot), which it superficially resembles. Neither of these knots should be used as a bend knot for attaching two ropes together.

What is an Aberdeen knot?
The Aberdeen knot is an alternative knot used when ending a continuous suture line, most often for subcutaneous and intradermal closure. When used in subcutaneous closure, this knot allows the surgeon to continue directly to an intradermal closure without cutting the subcutaneous suture line.
How many knots are in a suture?
The literature on the accepted number of throws per type of suture material has been largely anecdotal, often referring to 3 throws for silk, 4 for polyglactin 910 (Vicryl), five for polydioxanone(PDS), and six for polyproprolene (Prolene).
What are the types of sutures?
These types of sutures can all be used generally for soft tissue repair, including for both cardiovascular and neurological procedures.
- Nylon. A natural monofilament suture.
- Polypropylene (Prolene). A synthetic monofilament suture.
- Silk. A braided natural suture.
- Polyester (Ethibond). A braided synthetic suture.
How many types of surgical knots are there?
Sutures play a crucial role in surgery. The knot is the weakest part of a suture and is generally the site of failure (1–3). Of the many types of knots, the following 4 are commonly used in small animal practice: square knot, surgeon’s knot, granny knot (technical error), and the sliding half-hitch.
When do you use Vicryl sutures?
Coated Vicryl is indicated for use in ligation or general soft tissue approximation. Vicryl Rapide is indicated only when short-term wound care is needed and for use in superficial soft tissue suturing.
Is there a difference between sutures and stitches?
Although stitches and sutures are widely referred to as one and the same, in medical terms they are actually two different things. Sutures are the threads or strands used to close a wound. “Stitches” (stitching) refers to the actual process of closing the wound.
Is Vicryl suture absorbable?
VICRYL Suture is a synthetic absorbable suture coated with a lactide and glycolide copolymer plus calcium stearate. It is indicated for use in general soft tissue approximation and/or ligation, including ophthalmic procedures, but not cardiovascular or neurological tissues.
