Granny knot
Simple
One throw, incomplete
Square

Areas of high tension
Not for use in vascular ligation
Slip Knot/ Half-Hitch
Accidental
Purposeful (managing tension, working in a cavity)
Buried knot
Upside down square knot
Absorbable suture, interrupted
Start and finish SQ or intradermal suture lines
Aberdeen Knot
Alternative to square knot at end of a continuous line

Challenging to perform
More suture material

Modified Miller’s
Constrictor Knot
Surgeon’s Knot
