First Claim
Patent Images
1. A tibial resection guide for a knee joint comprising:
- a support member including a longitudinal shaft;
a femoral referencing guide rotatably mounted on the longitudinal shaft and configured for referencing a femur of the knee joint, the referencing guide including a referencing slot;
a femoral referencing member having a stylus arm attached to a bar, the stylus arm configured for referencing a posterior condyle of a femur of the knee joint and the bar removably passing through the referencing slot;
a cutting guide rotatably coupled to the longitudinal shaft, the cutting guide defining a cutting slot, the cutting slot positioned at a fixed distance from the referencing slot; and
an adjustment mechanism operable to move the referencing guide and the cutting guide along the longitudinal shaft without changing the fixed distance.

10. A tibial resection guide for a knee joint comprising:
-
a support member including a longitudinal shaft; a femoral referencing guide rotatably mounted on the longitudinal shaft and configured for referencing a femur of the knee joint, the referencing guide including a referencing slot, the referencing guide independently rotatable about the longitudinal shaft; a first guide portion having a first flange, the first guide portion coupled to the longitudinal shaft and independently rotatable about the longitudinal shaft; a second guide portion having a second flange, the second guide portion coupled to the longitudinal shaft and independently rotatable about the longitudinal shaft, the first and second flanges rotatable between a first position of stacked alignment in which the first and second flanges are aligned over one another and define a cutting slot therebetween, and a second position in which the first and second flanges are out of stacked alignment, and wherein the first and second guide portions positioned under the referencing guide along the longitudinal shaft; a base member movably supported on the longitudinal shaft and positioned under the first and second guide portions; and an adjustment mechanism configured to move the referencing guide and the first and second guide portions along the longitudinal shaft by moving the base member along the longitudinal shaft. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A tibial resection guide for a knee joint comprising:
-
a support member including a longitudinal shaft; a referencing guide mounted on the longitudinal shaft, the referencing guide integrally forming a stylus arm configured for engaging posterior femoral condyles of a femur of the knee joint; a cutting guide coupled to the longitudinal shaft, the cutting guide positioned under the referencing guide and including first and second flanges independently rotatable relative to the longitudinal shaft between a first position of stacked alignment in which the first and second flanges are aligned over one another and define a cutting slot therebetween, and a second position in which the first and second flanges are out of stacked alignment, the first and second guide positioned are positioned under the referencing guide along the longitudinal axis, the cutting slot positioned at a fixed distance from the stylus arm; a base member movably supported on the longitudinal shaft and positioned under the first and second flanges; and an adjustment mechanism configured to move the referencing guide and the cutting guide along the longitudinal shaft without changing the fixed distance by moving the base member along the longitudinal shaft. - View Dependent Claims (19, 20)
