A bone fixation system includes an intramedullary rod, a cage that is configured to receive the intramedullary rod at least partially therethrough, and at least one fixator configured to connect the intramedullary rod to the cage. A method for repairing a bone defect in a patient using the bone fixation system includes implanting the cage into the bone defect, inserting at least a portion of the intramedullary rod into the cage, and securing the cage to the intramedullary rod using the fixator.

A composite comprising: a barrier, said barrier being configured to selectively pass water, and said barrier being degradable in the presence of water; a matrix material for disposition within said barrier, wherein said matrix material has a flowable state and a set state, and wherein said matrix material is degradable in the presence of water; and at least one reinforcing element for disposition within said barrier and integration with said matrix material, wherein said at least one reinforcing element is degradable in the presence of water, and further wherein, upon the degradation of said at least one reinforcing element in the presence of water, provides an agent for modulating the degradation rate of said matrix material in the presence of water.

A tibial implant may include a plurality of implant subunits. The implant subunits may be configured for individual insertion within a wedge-shaped-void of the tibia. The implant subunits may further be configured for assembly in order to provide an implant substantially covering an exposed portion of cortical bone formed when performing a surgical osteotomy. Methods and kits for insertion and assembly of implants are further described.

A prosthetic total knee replacement system comprises a distal femoral implant component, a tibial tray implant component and a fixed bearing tibial tray insert. The fixed bearing tibial tray insert is fixed to the tibial tray and articulates with the distal femoral implant component. The fixed bearing tibial tray insert component has a medial-lateral centerline and a stabilizing post. The stabilizing post has a medial-lateral centerline offset laterally from the medial-lateral centerline of the fixed bearing tibial tray insert.

Patient-specific guides for a tibial tubercle osteotomy are provided. The guides include a guide body defining a portion with a bone-engaging surface that conforms as a negative surface to a corresponding surface of a specific patient's tibia, and a guide portion that guides a surgical instrument to a specific location on the specific patient's tibia, wherein the bone-engaging surface and guide portion are configured during a pre-operative planning stage. Methods for performing a tibial tubercle osteotomy with the patient-specific guides are also provided.

An implant apparatus for use in uniting a pair of bone segments, the apparatus including a first stem configured to be implanted in an intramedullary cavity of a first bone segment; a second stem configured to be implanted in an intramedullary cavity of a second bone segment; and a connector for connecting the first stem to the second stem, the connector including a first connector segment and a second connector segment, wherein the first connector segment and the second connector segment are coupled together at a lap joint connection.

Proposed is a modular augment, and, more specifically, a modular augment in which an additional unit is separably coupled to a center unit so as to selectively couple the additional unit to the center unit according to the degree of a patient's bone loss so that the degree of bone reinforcement can be easily adjusted, and thus a manufacturer is capable of covering various types of patients even though the types of units are minimized, thereby reducing manufacturing costs, the number of products to be prepared for surgery by a user such as a hospital is remarkably reduced, thereby preventing the unnecessary costs and facilitating inventory management, and a patient can receive an optimal augment that is appropriate for the patient' condition.

A method and system provide and use a patellar implant. The patellar implant includes a superior portion, an inferior portion opposite to the superior portion, and an anterior portion. The superior portion being configured to reside below a patellar tendon and to elevate and/or tilt the patellar tendon. The inferior portion is configured to be seated in proximity to a tibia. The anterior portion is between the superior portion and the inferior portion. The anterior portion is placed in proximity to a patella. In one aspect, the method includes inserting the implant beneath the patellar tendon and between the patella and a position at which the patellar tendon is affixed to the tibia. In this aspect, the method also includes affixing the implant.
