A method of replacing an ACL with a graft. The method provides for the drilling bone tunnels in a femur and a tibia. A replacement graft is provided having first and second ends. A biodegradable composite screw is provided. The screw is made from a biodegradable polymer and a bioceramic or a bioglas
A method of replacing an ACL with a graft. The method provides for the drilling bone tunnels in a femur and a tibia. A replacement graft is provided having first and second ends. A biodegradable composite screw is provided. The screw is made from a biodegradable polymer and a bioceramic or a bioglass. At least one end of the graft is secured in a bone tunnel using the biodegradable composite screw.

1. A method of manufacturing, comprising: introducing a dry bioceramic and a dry biodegradable polymer including poly(lactic acid) and poly(glycolic acid) into an extruder;blending the dry biodegradable polymer and the dry bioceramic in the extruder to form a composite; andmolding the composite to form a surgical screw having a thread on an exterior surface thereof. 2. The method of claim 1, further comprising heating the dry biodegradable polymer and the dry bioceramic in the extruder. 3. The method of claim 1, further comprising cooling the composite before the molding of the composite. 4. The method of claim 1, further comprising creating pellets of the composite before the molding of the composite; wherein molding the composite includes molding the pellets. 5. A surgical apparatus, comprising: a bioabsorable screw made from a bioceramic and a bioabsorbable copolymer including poly(lactic acid) and poly(glycolic acid), the screw being formed by the method of claim 1. 6. The apparatus of claim 5, wherein the screw is bioabsorbable. 7. The apparatus of claim 5, wherein the screw is cannulated. 8. The apparatus of claim 5, wherein the bioceramic comprises a bioceramic selected from the group consisting of mono-, di-, tri, [alpha]-tri-, [beta]-tri and tetra-calcium phosphate, hydroxyapatite, calcium sulfates, calcium oxides, calcium carbonate, and magnesium calcium phosphates. 9. The apparatus of claim 5, wherein the bioabsorbable copolymer comprises about 85 mole percent to about 95 mole percent of poly(lactic acid) and about 5 mole percent to about 15mole percent of poly(glycolic acid). 10. A surgical method, comprising: introducing a graft into a bone; andafter introducing the graft, inserting a screw into the bone such that an exterior surface feature of the screw penetrates into the bone, thereby securing the graft in a fixed position between the screw and the bone, the screw comprising poly(lactic acid), poly(glycolic acid), and a bioceramic. 11. The method of claim 10, further comprising, before inserting the screw, mounting the graft to the bone. 12. The method of claim 10, further comprising, before inserting the screw, mating a distal end of a driver tool to a proximal end of the screw; wherein inserting the screw includes rotating the driver tool having the screw mated to the distal end thereof. 13. The method of claim 10, wherein the exterior surface feature is a thread. 14. The method of claim 10, wherein the screw is bioabsorbable. 15. The method of claim 10, wherein the screw is cannulated. 16. The method of claim 10, wherein the screw is bioabsorbable and is cannulated. 17. A surgical method, comprising: forming a bone tunnel in bone;securing a graft to the bone within the bone tunnel; androtating a screw into the bone tunnel such that the graft is pinned between the screw and a wall of the bone tunnel, the screw comprising poly(lactic acid), poly(glycolic acid), and a bioceramic. 18. The method of claim 17, wherein rotating the screw includes rotating a driver tool having the screw mounted on a distal end thereof. 19. The method of claim 17, wherein the screw is threaded, cannulated, and bioabsorbable. 20. The method of claim 17, wherein the bioceramic comprises a bioceramic selected from the group consisting of mono-, di-, tri, [alpha]-tri-, [beta]-tri and tetra-calcium phosphate, hydroxyapatite, calcium sulfates, calcium oxides, calcium carbonate, and magnesium calcium phosphates; and the copolymer comprises about 85 mole percent to about 95 mole percent of poly(lactic acid) and about 5 mole percent to about 15 mole percent of poly(glycolic acid).
