Distal Femoral Cutting Guide
First Claim
1. An apparatus for resecting the distal face of the femur at a predetermined valgus angle relative to the patient'"'"'s intramedullary canal prior to implanting the femoral component of a total knee prosthesis, comprising:
- a) a distal elongate sword having a longitudinal axis and being adapted for insertion into the intramedullary canal of the femur;
b) a proximal handle connected to and having a longitudinal axis coaxial with said sword;
c) a base cartridge being fixed intermediate said sword and handle and having an axial passage extending therethrough;
d) a face plate at the distal end of the base cartridge adapted to abut the face of the natural distal femur, said plate oriented at the predetermined valgus angle relative to the longitudinal axis of the sword; and
,e) a cutting jig having;
(i) a guide plate with at least one blade slot adapted to receive and guide a cutting blade; and
, (ii) a bracket that supports said guide plate and detachably engages said axial passage and orients said at least one blade slot at the predetermined valgus angle relative to the longitudinal axis;
wherein said apparatus can be attached to and used for resecting either the left or right femur.

Abstract
An apparatus for resecting the distal face of either the left or right femur at a predetermined valgus angle relative to the patient'"'"'s intramedullary canal prior to implanting the femoral component of a total knee prosthesis. The apparatus has a distal elongate sword having a longitudinal axis and being adapted for insertion into the intramedullary canal of the femur. A proximal handle is connected to and has a longitudinal axis coaxial with the sword. A base cartridge is fixed intermediate the sword and handle and has an axial passage extending therethrough. A face plate is fixed at the distal end of the base cartridge and is adapted to abut the face of the natural distal femur. The face plate is oriented at the predetermined valgus angle relative to the longitudinal axis of the sword. A cutting jig connects to the base cartridge. The cutting jig has a guide plate with at least one blade slot adapted to receive and guide a cutting blade, and a bracket that supports the guide plate and detachably engages the axial passage and orients the at least one blade slot at the predetermined valgus angle relative to the longitudinal axis.

12. An apparatus for resecting the distal face of the femur at a predetermined valgus angle relative to the patient'"'"'s intramedullary canal prior to implanting the femoral component of a total knee prosthesis, comprising:
-
a) an elongate rod having a distal sword portion for insertion into the intramedullary canal of the femur and a proximal handle portion, said rod having a longitudinal axis that aligns with the patient'"'"'s intramedullary canal; b) a cutting jig having a support bracket and a guide plate with at least one blade slot adapted to receive and guide a cutting blade; c) means for mounting the cutting jig on said rod in a first orientation wherein the guide plate is arranged to resect the left femur at the predetermined valgus angle, and for mounting the cutting jig on said rod in second orientation wherein the guide plate is arranged to resect the right femur at the predetermined valgus angle. - View Dependent Claims (13, 14, 15, 16, 17, 18)
