Abstract
A tibial implant includes one or more stiffness-modifying features to reduce the stiffness of one or more sections of the tibial implant. The stiffness-modifying features may include slots, recesses, or passageways defined in various locations of the tibial implant to selectively reduce the stiffness of a tibial insert and/or tibial base of the tibial implant.
Claims7
A tibial insert of a tibial implant, the tibial insert comprising:
- a medial articular surface;
- a lateral articular surface;
- and
- a central body formed between the medial articular surface and the lateral articular surface, wherein the central body includes a stiffness-modifying feature that selectively reduces stiffness of one or more sections of the tibial insert when implanted,
- wherein the stiffness-modifying feature includes (i) a passageway extending through the central body from an anterior side of the tibial insert to a posterior side of the tibial insert, and (ii) a groove defined on a top surface of the central body from the anterior side of the tibial insert to the posterior side of the tibial insert, wherein the groove is in fluid communication with the passageway,
- wherein the tibial insert further comprises a therapeutic agent disposed in the passageway.
