Patent number: 9351835Abstract: The embodiments provide provides devices, instruments, and associated methods for treating joint pain. A joint is evaluated using magnetic resonance imaging to detect any defects in the subchondral bone. For example, using T2-weighted MRI images, bone marrow lesions or edemas can be identified, and using T1-weighted MRI images, associated regions of sclerotic bone adjacent to the bone marrow lesion can be identified. The treatment method may involve introducing a bone void filler material at the site to address the bone marrow lesion or edema, and/or drilling and inserting an implant to address the sclerotic bone, bone marrow lesion or edema, and insufficiency or stress fractures. An access path is mapped to a location in the subchondral region where the insufficiency fracture resides. The access path attempts to preserve an articular surface of the joint. A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path.Type: GrantFiled: May 28, 2015Date of Patent: May 31, 2016Assignee: ZIMMER KNEE CREATIONS, INC.Inventors: Peter F.

Patent number: 9314343Abstract: An orthopaedic tibial prosthesis includes a tibial baseplate sized and shaped to cover substantially all of a resected proximal tibial surface, and a tibial bearing component sized to leave a posteromedial portion of the tibial baseplate exposed when the tibial bearing component is mounted to the baseplate. The exposed posteromedial portion of the tibial baseplate includes a chamfered profile which cooperates with a correspondingly chamfered profile at a posteromedial edge of the tibial bearing component to create a substantially continuous chamfer extending from the resected tibial surface to the medial articular surface of the tibial bearing component. Advantageously, this chamfer leaves an absence of material (i.e., a relief or void) at the posteromedial edge of the tibial prosthesis, thereby enabling deep flexion of the prosthesis without impingement between the tibial prosthesis and adjacent anatomic tissues or prosthetic structures.Type: GrantFiled: September 24, 2013Date of Patent: April 19, 2016Assignee: Zimmer, Inc.Inventors: Raymond C.
