ABSTRACT
A suture knot is the starting point of most suture patterns. The ability to tie a proper suture knot is essential for successfully completing any suture pattern. The basic interrupted suture pattern is used to securely close a wound with accuracy of tissue apposition. It can be used in skin, muscle, organs, vessels, nerves, or fascia. The simple interrupted suture pattern is easy to place, has good tensile strength, and has less potential for wound edema. This is a secure pattern that allows the surgeon to make adjustments as needed to align the wound edges while suturing. The interrupted horizontal mattress suture pattern provides good strength and wound eversion. The continuous horizontal mattress suture pattern allows for faster wound closure than the interrupted horizontal mattress suture pattern; however, failure of either knot may result in failure of the entire suture pattern.
