Polydioxanone is a monofilament absorbable suture that elicits minimal reaction, is slowly absorbed, and maintains tensile strength for extended periods. It maintains 70% of its tensile strength at 2 weeks, 50% at 4 weeks, and 25% at 6 weeks with complete absorption in approximately 180 days (Bellenger 1982; Ratner et al. 1994; Roush 2003). Initial tensile strength for polydioxanone is greater than surgical gut, polyglycolic acid, or polyglactin 910, but it has the poorest knot security of the synthetic absorbable sutures (Boothe 1998). It is useful when prolonged support of healing tissue is desired (Tan et al. 2003).
