A system that can be used in a knee replacement procedure can include a tibial cut guide and an alignment guide. The tibial cut guide can have a first guide portion coupled to and adjustable relative to a second guide portion. The first guide portion can be configured to define a sagittal cut slot and a proximal cut slot. The alignment guide configured for extramedullary mounting to the patient and configured to couple with the second guide portion of the tibial cut guide, the alignment guide having a first mechanism and a second mechanism of differing construction, the first mechanism and the second mechanism are both configured to be actuated to facilitate extension and retraction of the alignment guide to position the tibial cut guide in a desired proximal-distal location relative a tibia of a patient when the tibial cut guide and the alignment guide are assembled together.

Assembly and system including a tibial cut guide

Systems and apparatuses including a system that can be used in a knee replacement procedure are disclosed. According to one example, the system can include a tibial cut guide and an alignment guide. The tibial cut guide can have a first guide portion coupled to and adjustable relative to a second guide portion. The first guide portion can be configured to define a sagittal cut slot and the second guide portion can be configured to define a proximal cut slot. The alignment guide can be configured for extramedullary mounting to the patient and can be configured to couple with the second guide portion of the tibial cut guide. The alignment guide can have a first mechanism and a second mechanism of differing construction. The first mechanism and the second mechanism can both be configured to be actuated to facilitate extension and retraction of the alignment guide to position the tibial cut guide in a desired proximal-distal location relative a tibia of a patient when the tibial cut guide and the alignment guide are assembled together.

The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.

Modular stem extension

Methods and apparatuses for attaching tissue structures to orthopaedic implants. In one exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal tibial implant. In another exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal femoral implant.

Femoral provisional prosthesis with cut guide

Combination modular femoral provisional prosthesis with cut guide

An easily assembled provisional orthopaedic implant having first and second components. The first component may include a stem which can be inserted into an intramedullary canal and may be a femoral component of a knee joint prosthesis. The second component has a body and a sliding retention member. The retention member can be manually engaged with a groove on the stem of the first component to lock the two components together. The second component may form of an intercondylar box and have a projecting tab engageable with a recess on the femoral component to properly orient the two components when they are placed in registry with each other.
