The role of sutures is to maintain incised or injured tissue in apposition to allow the tissue to heal (Bellenger 1982; van Rijssel et al. 1989; Roush 2003). The ideal suture material would provide high tensile strength for a sufficient time to allow the tissue to heal, have good knot security, resist infection, and cause no inflammatory, immunogenic, or carcinogenic reactions. The reaction of tissue to sutures depends on several variables such as the type, quantity, and duration of suture implantation as well as the tissues into which suture is implanted.

Surgeons must be familiar with different suture materials in order to make the most appropriate choice for specific clinical situations (Ratner et al. 1994). It is important to have a thorough understanding of the tissues, healing time required, the time the suture retains sufficient tensile strength to support the tissues as they heal, and time to complete absorption. The suture that is chosen may affect wound healing, functional outcome, and cosmetics. The number of suture types available has increased dramatically, and each suture type has specific physical, handling, and tissue reaction characteristics. Sutures are classified in many ways based on their ability to be absorbed and whether they are single, stranded, or braided. Different suture properties can also affect the knot security which must also be considered when choosing suture materials (Marturello et al. 2014).
