PATIENT-SPECIFC PARTIAL KNEE GUIDES AND OTHER INSTRUMENTS

摘要

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.
