  • Patient-specific partial knee guides and other instruments
    Patent number: 8979856
    Abstract: A surgical kit for unicompartmental knee arthroplasty includes a unitary patient-specific unicompartmental tibial guide and a tibial drill template and other instruments. The tibial guide has a patient-specific body with an inner surface preoperatively configured to nestingly conform and mate in only one position with an anterior portion and a proximal portion of one compartment of a tibial bone of a specific patient. The tibial guide includes a drill guide portion preoperatively configured for drilling first and second anterior holes into the tibial bone for guiding a horizontal tibial resection. The tibial guide includes a vertical resection guide portion preoperatively configured for guiding a vertical resection through the tibial bone before the horizontal resection.

  • Patient-specific high tibia osteotomy
    Patent number: 8828087
    Abstract: A surgical method for tibia osteotomy includes attaching a patient-specific alignment guide to a corresponding surface of a tibia of a patient for whom the alignment guide is customized during a pre-operative planning stage and making a partial bone cut in the tibia through a planar slot of the alignment guide. The planar slot is oriented at a patient-specific angle relative to an anatomic axis of the patient and the angle is customized during the pre-operative planning stage. The method includes opening the bone cut to form an opening wedge, and inserting a patient-specific implantable wedge into the opening wedge.
