Abstract
Apparatus for performing an open wedge, high tibial osteotomy, the apparatus comprising: cutting apparatus for forming an osteotomy cut in the tibia, the cutting apparatus comprising: targeting apparatus for identifying a cutting plane through the tibia and a boundary line for terminating a cut made along the cutting plane, wherein the boundary line is located within the tibia, parallel to the anterior-posterior slope of the tibia and parallel to the sagittal plane of the patient. A method for performing an open wedge, high tibial osteotomy, the method comprising: positioning targeting apparatus for identifying a cutting plane through the tibia and a boundary line for terminating a cut made along the cutting plane, wherein the boundary line is located within the tibia, parallel to the anterior-posterior slope of the tibia and parallel to the sagittal plane of the patient; cutting the bone along the cutting plane, with the cut terminating at the boundary line; moving the bone on either side of the cut apart so as to form the wedge-like opening in the bone; and stabilizing the bone.
