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 surgical method, comprising: mounting an end of a graft to bone within a bone tunnel formed in the bone; androtating a screw into the bone tunnel between an inner wall of the bone tunnel and the mounted end of the graft, thereby threading the screw into the inner wall of the bone tunnel and the
1. A surgical method, comprising: mounting an end of a graft to bone within a bone tunnel formed in the bone; androtating a screw into the bone tunnel between an inner wall of the bone tunnel and the mounted end of the graft, thereby threading the screw into the inner wall of the bone tunnel and thereby securing the end of the graft in a fixed position between the screw and the inner wall of the bone tunnel, the screw being biodegradable and being made from poly(lactic acid), poly(glycolic acid), and a bioceramic. 2. The method of claim 1, wherein the bone comprises a femur. 3. The method of claim 1, wherein the bone comprises a tibia. 4. The method of claim 1, wherein the bone comprises a femur; and the method further comprises: mounting a second end of the graft to a tibia within a tibial bone tunnel formed in the tibia; androtating a second screw into the tibia bone tunnel between an inner wall of the tibia bone tunnel and the mounted second end of the graft, thereby threading the second screw into the inner wall of the tibia bone tunnel and thereby securing the end of the graft in a fixed position between the screw and the inner wall of the bone tunnel, the second screw being biodegradable and being made from poly(lactic acid), poly(glycolic acid), and a bioceramic. 5. The method of claim 1, wherein the end of the graft includes a bone block such that the screw is threaded into the inner wall of the bone tunnel and into a surface of the bone block. 6. The method of claim 1, 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. 7. The method of claim 1, wherein the bioceramic comprises [beta]-tricalcium phosphate. 8. The method of claim 1, wherein the poly(lactic acid) and the poly(glycolic acid) are a copolymer comprising 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). 9. A surgical apparatus, comprising: a cannulated bioabsorbable screw made from a bioceramic and a bioabsorbable copolymer including poly(lactic acid) and poly(glycolic acid), the screw having a thread extending around an exterior surface thereof. 10. The apparatus of claim 9, 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. 11. The apparatus of claim 9, wherein 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). 12. The apparatus of claim 9, wherein the thread spirals along an entire longitudinal length of the screw. 13. A surgical system, comprising: a bioabsorable screw made from a bioceramic and a bioabsorbable copolymer including poly(lactic acid) and poly(glycolic acid), the screw having a thread on an exterior surface thereof, and a proximal end of the screw including a mating feature; anda driver including a mating element at a distal end thereof, the mating element being configured to engage the mating feature at the proximal end of the screw, the driver being configured to be rotated, with the mating feature engaged with the mating element, so as to rotate the screw and threadably engage the thread with a bone. 14. The system of claim 13, wherein the screw is cannulated. 15. The system of claim 14, further comprising a guide wire configured to extend through the inner lumen. 16. The system of claim 14, wherein the driver is cannulated; and the system further comprises a guide wire configured to extend through cannulated interiors of the screw and the driver during the rotation of the driver and the screw. 17. The system of claim 13, wherein the mating feature includes a socket formed in the proximal end of the screw. 18. The system of claim 13, 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. 19. The system of claim 13, wherein the bioceramic comprises [beta]-tricalcium phosphate. 20. The system of claim 13, wherein 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).
