- Page 4 PROXIMAL TIBIAL RESECTION The tibial pin guide (in addition to the product packaging label) will have patient specific identifiers: Patient Name, Lot No., Size and Patient Anatomy (R/L). Verify the accuracy of these identifiers prior to opening the sterile package (Figure 1). Note: The size information was selected pre- operatively based on the Patient Proposal.
- Page 5 With the knee flexed at 90 degrees, place the tibial resection guide with uprod assembly onto the proximal anterior medial aspect of the tibia and both plateaus. Avoid using excessive force to seat the guide. Apply most of the force anterior to posterior while holding the guide as described.
- Page 6 PROXIMAL TIBIAL RESECTION After drilling the two anterior pins, the TRUMATCH Solutions Drill Guides are removed by twisting in a counter-clockwise direction, while leaving the two anterior pins in place (Figure 7). Remove the tibial pin guide by moving it up and pulling it away from the anterior fixation pins.
- Page 7 DISTAL FEMORAL RESECTION The femoral pin guide (in addition to the product packaging label) will have patient specific identifiers: Patient Name, Lot No., Size and Patient Anatomy (R/L). Verify the accuracy of these identifiers prior to opening the sterile package (Figure 9). Note: The size information was selected pre- operatively based on the Patient Proposal.
- Page 8 DISTAL FEMORAL RESECTION Evaluate the lack of toggling or rocking of the femoral pin guide to confirm the optimum placement of the guide. It is not uncommon to see a 1 to 2 mm gap around the periphery of the guide. Next drill two anterior pins and two distal pins through the drill guides (Figure 12).
- Page 9 Evaluate the distal cut using the reference guide or angel wing (Figure 14A). If needed, the block may be shifted 2 mm proximally or distally by selecting the appropriate offset holes adjacent to the “0” mm hole. For additional stability during the cut, an optional third, fixation pin can be placed through the cutting block in either the lower medial or lateral holes.
- Page 10 FEMORAL PREPARATION - A/P AND CHAMFER CUTS Attach the HP Universal Handle to the Femoral Fixed Reference Guide (P/N 2004-20-920) and position the guide’s spikes through the “0” mm holes marked with a square located at the bottom of the SIGMA Femoral Fixed Reference Femoral 4-in-1 Cutting Block (Figure 15).
- Page 11 Note: If the Femoral Fixed Reference Guide (P/N 2004-20-920) is unavailable, two fixation pins can be inserted in the previously drilled distal femoral holes and used to set the location of the HP Femoral 4-in-1 Cutting Block. The TRUMATCH Solutions Femoral Pin Guide is designed to position the pin holes posteriorly on the femur which maintains the ability to move the block to resect 2 mm more bone anterior...

- Page 13 INTRA-OPERATIVE CONSIDERATIONS Fixation Pins and Saw Blades a. The SIGMA HP Threaded Headless Sterile Pins (P/N 9505-02-302), combined with the HP driver (P/N 9505- 02-071) are recommended for firmly securing the guides, especially when used in soft bone. b. For efficient resection of large bones, select the longest blade possible, such as 12.7 mm wide x 1.19 mm thick (The blade is 13 mm wide and 21 mm wide at teeth.).
- Page 14 SURGICAL TIPS AND PEARLS Tibial Resection Guide a. The tibial guide’s primary reference surface is the anterior/medial aspect of the tibia. This area, roughly triangular in shape, matches the guide’s largest surface contact area (Figure 21). When positioning the guide, apply most of the pressure (~75%) against the anterior aspect of the tibia.
- Page 16 Indications For Use: The TRUMATCH Patient Specific Instruments are intended to be used as patient-specific surgical instrumentation to assist in the positioning of a joint replacement component intra-operatively and in guiding the marking of bone before cutting. The anatomical landmarks necessary for the creation of the TRUMATCH Patient Specific Instruments must be present and identifiable on CT. The TRUMATCH Patient Specific Instruments are intended for use with SIGMA ®...
