Disclosed is a method of selecting a femoral prosthetic for implantation relative to a femur using a femoral sizing guide. An extension portion of the femoral sizing guide is placed adjacent to a posterior condyle surface of the femur. A stylus is located proximate to an interior condyle surface of the femur. A first actuator disposed between the extension portion and a base portion is moved to rotatably displace the extension portion with respect to the base portion until the stylus is centrally located on top of the interior condyle. A measurement of the femur is identified with the sizing guide based on a relative location of the stylus, the extension portion and the base portion. A femoral prosthesis is selected based on the measurement.
1. A method of selecting a femoral prosthetic for implantation relative to a femur using a femoral sizing guide, the method comprising: placing an extension portion of the femoral sizing guide adjacent to a posterior condyle surface of the femur, the extension portion having a base portion pivotally
1. A method of selecting a femoral prosthetic for implantation relative to a femur using a femoral sizing guide, the method comprising: placing an extension portion of the femoral sizing guide adjacent to a posterior condyle surface of the femur, the extension portion having a base portion pivotally connected thereto;locating a stylus proximate to an interior condyle surface of the femur;moving a first actuator disposed between the extension portion and the base portion to rotatably displace the extension portion with respect to the base portion until the stylus is centrally located on top of the interior condyle;identifying a measurement of the femur with the sizing guide based on a relative location of the stylus, the extension portion and the base portion; andselecting a femoral prosthesis based on the measurement;wherein moving the first actuator comprises rotating a worm gear disposed between the extension portion and the base portion. 2. The method of claim 1, further comprising: translating the stylus along an axis relative to the base portion. 3. The method of claim 2 wherein translating the stylus further comprises translating a superstructure associated with the stylus along the axis and relative to the extension portion. 4. The method of claim 3 wherein translating the stylus comprises rotating a second actuator causing a threaded distal end of the second actuator to rotate within a threaded hole of the base portion. 5. The method of claim 2 wherein translating the stylus comprises translating the stylus relative to drill guides extending from the superstructure. 6. The method of claim 1 wherein identifying the measurement comprises identifying a first gradation of a plurality of indexing gradations provided on a worm gear mount of the worm gear. 7. The method of claim 6 wherein identifying the measurement further comprises identifying a second gradation of a series of gradations provided on the stylus. 8. The method of claim 1, further comprising: drilling at least one retaining hole into the femur referencing drilling guides extending from the superstructure. 9. A method of selecting a femoral prosthetic for implantation relative to a femur using a femoral sizing guide, the method comprising: placing an extension portion of the femoral sizing guide adjacent to a posterior condyle surface of the femur, the extension portion having a base portion pivotally connected thereto;locating a stylus extending from a superstructure proximate to an interior condyle surface of the femur;sliding the stylus within an index slot of the superstructure to position a tip of the stylus relative to the interior condyle surface of the femur;rotatably displacing the extension portion with respect to the base portion until the stylus is centrally located on top of the interior condyle by moving a first actuator;translating a superstructure associated with the stylus along an axis and relative to the extension portion by rotating a second actuator, the second actuator is laterally spaced apart from the axis;identifying a measurement of the femur with the sizing guide based on a relative location of the stylus, the extension portion and the base portion; andselecting a femoral prosthesis based on the measurement. 10. The method of claim 9 wherein rotatably displacing the extension portion comprises moving a first actuator disposed between the extension portion and the base portion. 11. The method of claim 10 wherein translating the superstructure comprises rotating the second actuator causing a threaded distal end of the second actuator to rotate within a threaded hole of the base portion. 12. The method of claim 10 wherein translating the superstructure moves drill guides relative to the base portion. 13. The method of claim 10 wherein rotatably displacing the extension portion comprises rotating a worm gear disposed between the extension portion and the base portion. 14. The method of claim 13 wherein identifying the measurement comprises identifying a first gradation of a plurality of indexing gradations provided on a worm gear mount of the worm gear. 15. The method of claim 14 wherein identifying the measurement further comprises identifying a second gradation of a series of gradations provided on the stylus. 16. The method of claim 8, further comprising: drilling at least one retaining hole into the femur referencing drilling guides extending from the superstructure. 17. A method of selecting a femoral prosthetic for implantation relative to a femur using a femoral sizing guide, the method comprising: placing an extension portion of the femoral sizing guide adjacent to a posterior condyle surface of the femur, the extension portion having a base portion pivotally connected thereto;locating a stylus extending from a superstructure proximate to an interior condyle surface of the femur;sliding the stylus within an index slot of the superstructure to position a tip of the stylus relative to the interior condyle surface of the femur;rotating a worm gear disposed between the extension portion and the base portion to displace the extension portion with respect to the base portion until the stylus is centrally located on top of the interior condyle;translating the stylus relative to the base portion;identifying a measurement of the femur with the sizing guide based on a relative location of the stylus, the extension portion and the base portion; andselecting a femoral prosthesis based on the measurement. 18. The method of claim 17 wherein translating the stylus comprises rotating an actuator causing a threaded distal end of the actuator to rotate within a threaded hole of the base portion.
