Classification of surgical sutures

Depending on their chemical and physical characteristics, sutures can be divided into 

Monofilament sutures have no interstices in which to lodge bacteria, but they are more difficult to handle and require more throws to each knot for security than braided sutures. Multifilament sutures are generally easier to handle, with greater knot security, but do allow capillarity and interstitial bacteria colonization which can increase the risk of wound infection, particularly with nonabsorbable sutures. Both monofilament and multifilament sutures can be absorbable or nonabsorbable.
