Patent number: 10646326Abstract: 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.

Patent number: 9918845Abstract: Augments systems and methods for attaching two or more augments to an underside (50) of a tibial baseplate (16) are disclosed. An augment system (100) can include a first augment (102) having a superior surface (106) and an inferior surface (108), the superior surface configured for attachment to the underside of the tibial baseplate. The augment system can include a second augment (104) having a superior surface (110) and an inferior surface (112), the superior surface configured for attachment to the inferior surface of the first augment. The first and second augments can be formed of different materials. One or more additional augments can be used with the first and second augments, and the augment system can be stacked on a resected surface of the tibia. In an example, the augment that directly contacts the resected surface of the tibia can be formed of a porous material, such as to facilitate bone growth.Type: GrantFiled: November 13, 2014Date of Patent: March 20, 2018Assignee: Zimmer, Inc.Inventors: Keith A.

Patent number: 9517138Abstract: A tibial support structure includes a platform portion and a medullary portion that are monolithically formed as a single piece. The medullary and platform portions of the augment component are adapted to accommodate and mechanically attach to a tibial baseplate, and are individually shaped and sized to replace damaged bone stock both within the tibia, as well at the tibial proximal surface. The monolithic formation of the tibial support structure provides a strong and stable foundation for a tibial baseplate and facilitates restoration of the anatomic joint line, even where substantial resections of the proximal tibia have been made. The tibial support structure may be made of a bone-ingrowth material which facilitates preservation and rebuilding of the proximal tibia after implantation, while also preserving the restored joint line by allowing revision surgeries to be performed without removal of the tibial support structure.Type: GrantFiled: November 21, 2014Date of Patent: December 13, 2016Assignee: Zimmer, Inc.Inventors: Ray Zubok, Jorge Montoya, Timothy A. Hoeman, John Chernosky, Keith A. Roby
