Patient-Specific Knee Alignment Guide And Associated Method

摘要

A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.

1. A method for accessing a portion of a bone of a patient relative to a soft tissue on a surface of the bone, comprising:
mating a patient-specific three-dimensional curved inner surface of a first guide onto a corresponding three-dimensional surface of the bone, the patient-specific three-dimensional curved inner surface preoperatively configured from three dimensional images of the bone, where the first guide is based on converted scan data to three dimensional images of the bone of the patient's anatomy including a knee joint anatomy including images of the knee joint surfaces of at least one of a distal femur bone or a proximal tibial bone with or without associated soft tissue on the distal femur bone or the proximal tibial bone; drilling a first hole into the bone surface through a first guiding aperture of the first guide; and placing a member in the first hole into the bone near the knee joint surface.
