Tibial tubercle osteotomy
First Claim
Patent Images
1. A patient-specific system for a tibial osteotomy, comprising:
- a patient-specific guide comprising a guide body defining,a bone-engaging portion with a bone-engaging surface, wherein the bone-engaging surface is configured during a pre-operative planning stage of a tibial osteotomy to conform as a negative surface to a corresponding surface of a specific patient'"'"'s tibia at, around, or near the patient'"'"'s tibial tubercle;
a first planar slot oriented at a first predetermined angle and at a first predetermined position relative to a proximal-distal axis of the specific patient'"'"'s tibia that is selected during the pre-operative planning stage of the tibial osteotomy;
a second planar slot oriented at a second predetermined angle and at a second predetermined position relative to the proximal-distal axis of the specific patient'"'"'s tibia that is selected during the pre-operative planning stage of the tibial osteotomy; and
a plurality of apertures.

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.
