    摘要: A fiber-reinforced, polymeric implant material useful for tissue engineering, and method of making same are provided. The fibers are preferably aligned predominantly parallel to each other, but may also be aligned in a single plane. The implant material comprises a polymeric matrix, preferably a biodegradable matrix, having fibers substantially uniformly distributed therein. In preferred embodiments, porous tissue scaffolds are provided which facilitate regeneration of load-bearing tissues such as articular cartilage and bone. Non-porous fiber-reinforced implant materials are also provided herein useful as permanent implants for load-bearing sites.

    摘要: Various exemplary methods and devices are provided for fixing an implant to native tissue, such as bone. The devices can include a body with a tissue implant receiving opening and an aperture for receiving a fixation device. The body provides a large contact area for fixing the tissue implant to bone, such that the implant can be securely held in position without requiring penetration of the implant. Also provided is a tissue implant that includes pre-formed buckets for receiving fixation devices. The fixation devices can be positioned in the buckets of the tissue implant and implanted in bone holes without contacting native tissue.

    摘要: Various exemplary methods and devices are provided for fixing an implant to native tissue, such as, bone. The devices can include a body having an upper surface, a lower tissue contacting surface, and an implant receiving opening extending therebetween. The body can further include first and second portions each having an implant contacting surface and a hinge for connecting the first and second portions. In use, the hinge can allow pivotal movement between the first and second portions such that an implant can be fixed therebetween.
