What are the disadvantages of polypropylene sutures?The core of the suture contains less oriented, and weaker, polymer crystals with less tensile strength. This explains why physical damage to the “hardened” outer layer of any polypropylene suture from a stray knot, kinking, or a pinch with forceps will cause early breakage or failure.

Polypropylene suture is a synthetic monofilament suture with greater tensile strength and less tissue adherence compared to nylon. It is commonly used for pull-out subcuticular sutures and running sutures on the face in medical procedures.The core of the suture contains less oriented, and weaker, polymer crystals with less tensile strength. This explains why physical damage to the “hardened” outer layer of any polypropylene suture from a stray knot, kinking, or a pinch with forceps will cause early breakage or failure.
