Are Silk Sutures Absorbable

Silk suture, composed of a protein called fibroin, is not absorbed. Silk suture has a smooth flow through tissue while maintaining knot security, and it is indicated for use in general soft tissue approximation and/or ligation. Although silk suture is not absorbed, progressive degradation of the proteinaceous silk fiber in vivo may result in a gradual loss of the suture tensile strength over time.
