1. An implant comprising:

a central portion composed of at least two yarns including at least one primary yarn and at least one high strength yarn interconnected to form openings therein; and

a peripheral portion extending around the central portion, the peripheral portion formed solely from at least one high strength yarn interconnected to form openings therein.

2. The implant according to claim 1 , wherein the at least two yarns of the central portion are interconnected via one of knitting, weaving, and combinations thereof.

3. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion has a tensile strength of at least 1 Gpa.

4. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion has a tensile strength that is at least 2 times stronger than that of the at least one primary yarn of the central portion.

5. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion has a tensile strength that is at least 5 times stronger than that of the at least one primary yarn of the central portion.

6. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion has a tensile strength that is about 10 times stronger than that of the at least one primary yarn of the central portion.

7. The implant according to claim 1 , wherein one of the at least two yarns of the central portion includes a bi-component fiber.

8. The implant according to claim 7 , wherein the bi-component fiber includes a non-absorbable core.

9. The implant according to claim 8 , wherein the bi-component fiber includes an absorbable sheath surrounding the non-absorbable core.

10. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion is a monofilament yarn.

11. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion is a multifilament yarn.

12. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion is composed of ultra high molecular weight polyethylene.

13. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion is composed of high molecular weight polyethylene terephthalate.

14. The implant according to claim 1 , wherein the at least one high strength yarn of the peripheral portion includes a bi-component fiber.

15. The implant according to claim 14 , wherein the bi-component fiber includes a non-absorbable core.

16. The implant according to claim 15 , wherein the bi-component fiber includes a non-absorbable sheath surrounding the non-absorbable core.

17. The implant according to claim 15 , wherein the non-absorbable core is ultra high molecular weight polyethylene.

18. The implant according to claim 1 , wherein the peripheral portion has a tensile strength that is at least 50% greater than a tensile strength of the central portion.

19. The implant according to claim 18 , wherein the tensile strength of the peripheral portion is about 100% greater than the tensile strength of the central portion.

20. The implant according to claim 18 , wherein the tensile strength of the peripheral portion is about 200% greater than the tensile strength of the central portion.

21. The implant according to claim 1 , wherein the central portion and the peripheral portion are formed of separate yarns, the at least one high strength yarn of the peripheral portion being interconnected in a different way than the at least two yarns of the central portion.

22. The implant according to claim 21 , wherein the at least two yarns of the central portion are warp knitted.

23. The implant according to claim 22 , wherein the at least one high strength yarn of the peripheral portion is welt knitted.
