Abstract
An apparatus for resecting a distal femoral condyle includes a resection guide defining a first bone fixation aperture extending about an axis. The resection guide further defines a first bone saw slot and a second bone saw slot. The resection guide is configured to position the first bone fixation aperture relative to the condyle. The resection guide is further configured to concurrently arcuately translate the first bone saw slot and the second bone saw slot relative to the axis. A knee replacement kit includes a femoral implant defining a first plan contour. The kit further includes a resection guide defining a second plan contour modeling the first plan contour.
Claims28
An apparatus for resecting a distal femoral condyle, the apparatus comprising:
- a resection guide defining a first bone fixation aperture extending about an axis, the resection guide further defining a first bone saw slot and a second bone saw slot;
- wherein the resection guide is configured to position the first bone fixation aperture relative to the condyle, and the resection guide is further configured to concurrently arcuately translate the first bone saw slot and the second bone saw slot relative to the axis.
An apparatus for resecting a distal femoral condyle, the apparatus comprising:
- means for defining an axis;
- means, coupled to the axis defining means, for defining a first bone saw slot;
- means, coupled to the axis defining means, for defining a second bone saw slot;
- means, coupled to the axis defining means, for positioning the axis relative to the condyle;
- and
- means, coupled to the axis defining means, for concurrently arcuately translating the first bone saw slot and the second bone saw slot relative to the axis.
A knee replacement kit, comprising:
- a femoral implant defining a first plan contour;
- and
- a resection guide defining a second plan contour modeling the first plan contour.
A kit for resecting a distal femoral condyle, the kit comprising:
- a femoral implant defining a first plan contour;
- and
- a resection guide defining a second plan contour modeling the first plan contour, the resection guide further defining a first bone fixation aperture extending about an axis, and the resection guide further defining a first bone saw slot and a second bone saw slot;
- wherein the resection guide is configured to position the first bone fixation aperture based on the anterior-posterior dimension of the distal femur, and the resection guide is further configured to concurrently arcuately translate the first bone saw slot and the second bone saw slot relative to the axis.
A method for resecting a distal femoral condyle, the method comprising the steps of:
- defining an axis;
- defining a first cutting path;
- defining a second cutting path;
- positioning the axis relative to the condyle;
- concurrently arcuately translating the first cutting path and the second cutting path relative to the axis;
- resecting the distal femur along the first cutting path;
- and
- resecting the distal femur along the second cutting path.
