Abstract: A method of surgically preparing a proximal end of a tibia includes inserting an intramedullary orthopaedic surgical instrument into a medullary canal of the tibia, securing an attachment device to the intramedullary orthopaedic surgical instrument, attaching a cutting block to the attachment device, resecting the proximal end of the tibia using the cutting block to form a surgically-prepared surface, positioning a tibial base trial on the surgically-prepared surface, and inserting a keel punch through a slot defined in the tibial base trial and into the surgically-prepared surface of the tibia.

Abstract: An orthopaedic surgical instrument assembly is disclosed. The assembly includes a tibial base trial adapted to be positioned on a surgically-prepared proximal end of a patient's tibia, a base fastener, and a stem adaptor secured to the base fastener. The stem adaptor includes a first adaptor body engaged with a lower surface of the tibial base trial and a second adaptor body pivotally coupled to the first adaptor body. A stem trial is removably coupled to the second adaptor body of the stem adaptor.

Abstract: An orthopaedic surgical instrument assembly includes a tibial base trial adapted to be positioned on a surgically-prepared proximal end of a patient's tibia, an intramedullary orthopaedic surgical instrument engaged with a lower surface of the tibial base trial, and a fastener configured to pivot relative to the tibial base trial. The fastener is configured to engage with the intramedullary orthopaedic surgical instrument to removably couple the intramedullary orthopaedic surgical instrument to the tibial base trial.

Abstract: An orthopaedic surgical instrument assembly includes an attachment device, an intramedullary orthopaedic surgical instrument, and a cutting block. The attachment device includes a housing, a rail extending outwardly from the housing, and a mounting frame positioned on the rail that is configured to slide relative to the housing along the rail. The intramedullary orthopaedic surgical instrument is removably coupled to the housing, and the cutting block is removably coupled to the mounting frame.
