A high strength abrasion resistant surgical suture material with improved tie down characteristics and tissue compliance includes poly(p-phenylene-2,6-benzobisoxazole) (PBO). The suture features a multifilament jacket formed of braided strands of PBO, optionally with fibers of polyester, silk, nylon or aramid strands as an enhancer. In one embodiment, the braided jacket surrounds a core formed of twisted strands of PBO. The suture has exceptional strength, is ideally suited for most orthopedic procedures, and can be attached to a suture anchor or a curved needle.

What is claimed is: 1. A braided suture suitable for use as a suture or ligature comprising fibers formed from filaments of poly(p-phenylene-2,6-benzobisoxazole) (PBO). 2. The braided suture of claim 1, further comprising at least one enhancement strand. 3. The braided suture of claim 2, wherein the enhancement strand is selected from the group consisting of polyester, silk, nylon, and aramid. 4. The braided suture of claim 1, wherein the braid is hollow. 5. The braided suture of claim 4, further comprising a core formed within the hollow braid. 6. The braided suture of claim 5, wherein the core comprises fibers formed from PBO filaments. 7. The braided suture of claim 5, wherein the core comprises twisted fibers. 8. The braided suture of claim 1, further comprising a synthetic or natural fiber other than PBO blended with the braided fibers of PBO. 9. The braided suture of claim 8, comprising a plurality of fibers of at least one long chain synthetic polymer or bioabsorbable fiber braided with the PBO. 10. The braided suture of claim 8, wherein the long chain synthetic polymer is polyester, nylon, or both. 11. The braided suture of claim 8, wherein PBO fibers comprise at least 40% of the braided fibers. 12. The braided suture of claim 8, wherein polyester fibers comprise less than about 40% of the braided filaments. 13. The braided suture of claim 2, wherein the at least one enhancement fiber comprises polyester strands. 14. A suture assembly comprising: a suture formed of a plurality of braided fibers of poly(p-phenylene-2,6-benzobisoxazole) (PBO); and a suture anchor attached to the suture. 15. The suture assembly as recited in claim 14, further comprising polyester fibers. 16. A suture assembly comprising: a suture formed of a plurality of braided fibers of poly(p-phenylene-2,6-benzobisoxazole) (PBO); and a half round, tapered needle attached to one or both ends of the suture. 17. A suture strand suitable for use as a suture or ligature including an outer jacket comprising a plurality of braided fibers of poly(p-phenylene-2,6-benzobisoxazole) (PBO).
