<p>Implants for osteo and osteochondral repair have been developed. These implants include a series of channels between the upper and lower surfaces of the implants, such that when implanted the lower surfaces are situated in an area rich in bone marrow and the channels provide a means for the bone marrow to migrate through the implant. Preferably the implants are made from resorbable polymer fibers, preferably arranged in braids that are knitted or woven together such that the braids are substantially parallel with each other. The implants may be rolled into a bundle of braids with the axis of the braids substantially parallel to the axis of the bundle, to provide channels along the axis of the bundle. A preferred embodiment includes P4HB fibers braided and knitted into a structure that is coated with a ceramic, preferably physiologic calcium phosphate.</p> |
