First claim
Opening claim text (preview).
The invention claimed is: 1. A method of resecting a distal end of a patient's femur comprising: advancing an orthopaedic surgical instrument assembly including a first customized patient-specific surgical instrument and a second customized patient-specific surgical instrument into contact with a distal end of the patient's femur to position a customized patient-specific negative contour of each posteriorly-extending arm of the first customized patient-specific surgical instrument over a portion of a corresponding positive contour of one of a patient's femoral condyles and position a customized patient-specific negative contour of the second customized patient-specific surgical instrument over a portion of a corresponding positive contour defining the patient's intercondylar notch, removing the second customized patient-specific surgical instrument from the first customized patient-specific surgical instrument so that the first customized patient-specific surgical instrument remains secured to the distal end of the patient's femur, and advancing a surgical tool through a cutting guide slot extending through a body of the first customized patient-specific surgical instrument. 2. The method of claim 1 , wherein removing the second customized patient-specific surgical instrument further comprises removing a boss attached to, and extending from, a body of the second customized patient-specific surgical instrument from a boss attached to, and extending from, the body of the first customized patient-specific surgical instrument. 3. The method of claim 1 , wherein removing the second customized patient-specific surgical instrument further comprises removing a plurality of tabs extending from a body of the second customized patient-specific surgical instrument from a plurality of catches formed in the body of the first customized patient-specific surgical instrument. 4. The method of claim 3 , wherein the catches are formed in brackets that extend distally from the body of the first customized patient-specific surgical instrument. 5. The method of claim 1 , further comprising advancing a cutting saw blade through the cutting guide slot.
