Abstract
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.
Claims6
A method for performing a tibial tubercle osteotomy on a patient's tibia, comprising:
- positioning a patient-specific guide on the patient's tibia, wherein the guide comprises a guide body defining a bone-engaging portion with a bone-engaging surface configured during a pre-operative planning stage of a tibial osteotomy to conform as a negative surface to a corresponding surface of the patient's tibia at, around or near the tubercle of the patient's tibia, and a plurality of apertures;
- resecting the tibia in three intersecting planes with a saw to generate a tubercle flap, wherein the patient-specific guide provides visual indicia for resecting;
- and
- repositioning the tubercle flap in an anterior direction or in both anterior and medial-lateral directions to form a gap between the tubercle flap and the resected surface of the tibia.
