Porous metal device for regenerating soft tissue-to-bone interface

摘要

The present disclosure relates, in some aspects, to orthopaedic implants for securing soft tissue to bone and methods for using the same. One particular implant comprises a first exposed porous surface region, having pores for promoting bone ingrowth, and a second exposed porous surface, having pores for promoting soft tissue ingrowth. At least some of the pores of the first exposed porous surface region may be seeded with osteocytic factors and at least some of the pores of the second exposed porous surface region may be seeded with fibrocytic factors. Such orthopaedic implants can advantageously facilitate regeneration of the soft tissue to bone interface.

主权项

1. An implant for securing soft tissue to bone, comprising:
a tubular body providing an inner passageway for receiving soft tissue of a patient, wherein said inner passageway includes an interior side wall provided by a tubular first open porous metal structure with pores of a first nominal pore diameter for suitably receiving soft tissue ingrowth, said tubular body including an exterior side wall provided by a plate-shaped second open porous metal structure with pores of a second nominal pore diameter greater than said first nominal pore diameter for suitably receiving bone ingrowth, wherein said plate-shaped second open porous metal structure is located to a side of said tubular first open porous metal structure along a length of said tubular first open porous metal structure such that said inner passageway does not pass through said plate-shaped second open porous metal structure.
