- Post 34 spans between condylar portions 14, 15.
- Holes 32, 33 receive a correspondingly shaped peg 82 on a trial wedge 77.
- Threaded fastener 81 of wedge 77 fits threaded opening 24 or 25 (see Figure 14) .
- a plurality of cutting guide slots are provided for cutting bone tissue at the patient's distal femur. Often bone is missing from the femur in the distal area. Bone has often been worn or eroded away in revision cases. The surgeon cleans up by cutting some bone from either the medial or lateral distal surface using a selected cutting guide slot 34A, 34B, 35A, 35B, 36A, 36B.
- Cutting guide slots 34A and 34B can be used to track and guide a cutting blade, saw, or the like during a cutting of tissue from the patient's distal femoral surface.
- guide slots 35A, 35B guide a cutting blade during a cutting of the distal femur.
- the cutting guide slots 36A, 36B are chamfer cutting guide slots for making anterior chamfer cuts on the patient's distal femur.
- Raised portions 37, 38 form a thickened reinforcement of trial body 11 at the cutting guide slots 34A, 35A, 36A and 34B, 35B, 36B.

- Module 50 has stem connector 60 with a flat surface 61 at the free end of stem 60.
- Stem 60 has a cylindrical base 64, tapered transition 63 and frustoconical surface 62 that enables a trial coupler 78 (see Figures 14-16) to preferably form a taper lock connection with stem 60 at surface 62.
- Trial coupler 78 can have upper projecting portion 79 that connects (e.g., a threaded connection) to a correspondingly threaded socket at the lower end of each stem 74, 75, 76.
- a selected stem extension 74, 75 or 76 could then be selectively connected to trial coupler 78 by a surgeon.
- the trial prosthesis 10 of the present invention enables a surgeon to vary the length and diameter of the stem portion of a trial body when fitting the trial body 11 and an attached trial coupler and/or a selected stem extension 74, 75 or 76 to a patient's surgically prepared femur.
- Coupler 78 has a lowermost socket 80 that corresponds in size and shape to stem connector 60 so that a taper lock connection can be formed between stem connector 60 and socket 80.
- stem connector 60 is inclined with respect to a plane 65 defined by surfaces 56, 57. The inclination is indicated by arrow 66 in Figure 11.
- Angle 66 can be between 80° - 90° for example, enabling the central axis 67 of stem connector 60 to compensate for the valgus angle of the patient's intramedullary canal at the distal femoral region.
- a generally cylindrically shaped stem extension 74, 75 or 76 affixed to connector 60 will form an angle 66 with the plane 65 of surfaces 56, 57.
- the surfaces 56, 57 register against flat surfaces 28, 29 of trial body 11.
- the surfaces 28, 29 are parallel to the surgically cut distal surface D of the patient's distal femur F (see Figure 7) .
- the surfaces 28, 29 (and 56, 57) are parallel to surface 20 of implant body 11 that fits against the surgically cut distal surface D of femur 11.
- Stem connector 60 attaches to flanges 51, 52 respectively with side walls 68, 69.
- the side walls 68, 69 have sharp cutting edges 68A, 69A proximally.
- the side wall 69 has a plurality of teeth 70 forming a rasping surface 71.
- This rasping surface 71 is helpful in revision cases as it cuts away excess bone as the surgeon taps or hammers the trial prosthesis 10 onto the distal femur F until the trial 10 reaches the position in Figure 7.
- Surface 69 is provided with rasping surface 71 because it is the surface that will likely engage excess bone due to the angle 66 of inclination of connector 60 (and its attached stem extension 74, 75 or 76) with respect to plane 65.
