Appl. No.:

17/122581

Inventors:

- Warsaw IN, US
Keith R. Berend - Columbus OH, US
Michael E. Berend - Indianapolis IN, US
Lance Dean Perry - Warsaw IN, US
Ryan John Schoenefeld - Fort Wayne IN, US

International Classification:

A61B 17/17
A61B 17/15
A61B 34/10
A61B 17/56

Abstract:

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.
