Abstract

Systems and methods are described for treating osteochondral pathologies. An implantable prosthesis for treating osteochondral pathologies includes: a porous substrate; and a substance positioned within the porous substrate that is elutable with regard to the porous substrate. The systems and methods provide advantages because a baited route is provided to attract mesenchymal stem cells from the cancellous bone underlying the articular surfaces up to chondral lesions within the joint, thereby promoting the growth of chondrocytes in the area of the chondral lesions.

Description

[0001] 1. Field of the Invention

[0002] The invention relates generally to the field of treating osteochondral pathologies. More particularly, the invention relates to methods and apparatus for implanting a substance eluting porous substrate into a bony defect to promote repair of osteochondral lesions.

[0003] 2. Discussion of the Related Art

[0004] Interventions for the treatment of chondromalacia and osteoarthritis include a variety of modalities, which include arthroscopic debriedment, microfracture techniques, intraarticular injection of medicaments, osteochondral transplants, and open surgical interventions such as chondrocyte transplantation via cell culturing techniques. None of these techniques has achieved the goal of offering a technically and economically feasible technique for promoting the growth of hyaline cartilage cells within osteochondral lesions.

[0005] Cartilaginous tissues covering the articulating ends of bones are composed of collagen, primarily Type II collagen a...
