Abstract: A method of surgically preparing a distal end of a femur for implantation of a femoral prosthetic component includes positioning a base cutting block and an intramedullary adaptor on the distal end of the femur such that a first end of the intramedullary adaptor is received in the medullary canal of the femur and the intramedullary adaptor is secured to the base cutting block, attaching a first modular cutting block to an anterior side of the base cutting block, resecting a first portion of the distal end of the femur using a cutting guide defined in the first modular cutting block, the cutting guide of the first modular cutting block, and resecting a second portion of the distal end of the femur using a base cutting guide defined in the base cutting block.

Abstract: A modular knee prosthesis system includes a femoral component having a stem and a sleeve. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by controlling the relative axial positions of the stem and the sleeve. Alternative options include providing sleeves with tapered bores of different diameters, providing a shim to be placed between the sleeve and the stem and providing the stems as adapters having different diameters.

Abstract: Surgical instruments for use in implanting a stem component into a knee of a patient include a canal reamer and an associated implant reference guide.

Abstract: An orthopaedic surgical instrument assembly is disclosed. The assembly includes an orthopaedic surgical instrument including a first surface, and a measurement gauge removably coupled to the orthopaedic surgical instrument. The gauge includes an arm having a tip positioned proximal to the orthopaedic surgical instrument, and a plurality of markings defined on the arm. Each marking indicates a predetermined distance from the first surface of the orthopaedic surgical instrument. The assembly may be used during an orthopaedic surgical procedure on a femur, which is also described herein.

Abstract: A modular knee prosthesis system includes a femoral component having a stem and a plurality of different sizes of sleeves mountable on the stem. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by selecting the size of sleeve that will provide the desired joint line. The different sizes of sleeves have different axial lengths but share a common geometry along a substantial part of their lengths so that the same bone cavity will accept multiple sizes of sleeves.

Abstract: An orthopaedic surgical instrument system includes a first broach including a first end configured to be separately secured to a handle and a tapered body having a plurality of cutting teeth defined therein, and a second broach including a first end configured to be separately secured to the handle in place of the first broach, a first tapered body extending distally from a second end positioned opposite the first end, and a second tapered body extending distally from the first tapered body. The tapered body of the first broach and the first tapered body of the second broach have a first outer geometry and the second tapered body has a second outer geometry different from the first outer geometry.

Abstract: A modular knee prosthesis system includes a femoral component having a stem, a plurality of different sizes of sleeves mountable on the stem, and a plurality of different sizes of augments mountable on the femoral component. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by selecting the size of sleeve that will provide the desired joint line. The different sizes of sleeves have different axial lengths but share a common geometry along a substantial part of their lengths so that the same bone cavity will accept multiple sizes of sleeves.

Abstract: An orthopaedic surgical instrument assembly includes a base block, an intramedullary orthopaedic surgical instrument configured to be inserted into a medullary canal of a patient's femur, an adaptor, and a modular cutting block. The base cutting block includes a slot, and the adaptor is positioned in the slot. The adaptor includes a mounting bracket engaged with the base plate, and a fastener coupled to the intramedullary orthopaedic surgical instrument. The modular cutting block is configured to be secured to the base block.
