POLYDIOXANONE Absorbable Sutures


Absorbable Sutures


Polydioxanone (PDS II) is a synthetic, absorbable, monofilament suture made from a polymer of paradioxanone (Figure 2). It has greater initial tensile strength than polyglycolic acid and polyglactin 910 but has the poorest knot security of all the synthetic absorbable sutures.24 The suture retains 74% of its tensile strength after 2 weeks, 50% after 4 weeks, and 25% after 6 weeks. There is minimal absorption by 90 days and absorption is not complete until 6–7 months after implantation.
