Tibial resection systems and methods for cruciate ligament retainment
First Claim
1. A tibial resection method, comprising:
- attaching a tibial block to a tibia;
securing an alignment guide, including one or more drill guides and a drill guide adjustment mechanism, to the tibial block;
selecting a tibial implant template to substantially match a size or shape of a proximal end of the tibia;
engaging the selected tibial implant template with the drill guide adjustment mechanism, moving the selected tibial implant template to a desired position on the proximal end of the tibia, including adjusting an axial direction of the one or more drill guides; and
drilling one or more guide pin holes in the tibia using the one or more drill guides, wherein the tibial block includes a horizontal member that includes an alignment guide retaining structure, and wherein the securing of the alignment guide to the tibial block includes positioning the alignment guide at any position along the alignment guide retaining structure, wherein the alignment guide retaining structure comprises a slot that is configured to receive one or more coupling projections on the alignment guide.

Abstract
Tibial resection systems and methods for use in a uni- or bi-cruciate retaining knee replacement procedure are disclosed. A tibial resection system can include a tibial block, an alignment guide, and a tibial implant template. The tibial block can be coupled to an anterior side of a tibia and longitudinally extend from a proximal end portion to a distal end portion. The alignment guide can be coupled to the proximal end portion of the tibial block and can include one or more drill guides and a drill guide adjustment mechanism. The tibial implant template can be engaged with the drill guide adjustment mechanism, such that rotational movement of the tibial implant template can adjust an axial direction of the one or more drill guides. An outer profile of the tibial implant template can be selected to substantially match an outer profile of a tibial prosthesis to be implanted.
