Bioabsorbable coating for a surgical article

A surgical suture or ligature having improved knot repositioning characteristics, comprising a bioabsorbable, multifilamentary strand manufactured from a polymer prepared from one or more monomers selected from the group consisting of glycolide, lactide, 1,3-dioxan-2-one and 1,4-dioxane-2-one, the strand having a bioabsorbable coating, the coating comprising a block copolymer having one or more A blocks comprising caprolactone, wherein the caprolactone in the one or more A blocks is about 40 percent by weight of the copolymer, and one or more B blocks manufactured from the monomer caprolactone randomly polymerized with one or more monomers selected from the group consisting of lactides, the total caprolactone linkages in the copolymer being about 70 percent by weight of said copolymer, wherein the coating comprises about 1/10 to 5 percent by weight of the coated suture or ligature.
