1 Customized Patient Instruments for Total Knee Replacement

3 Delivering customized patient instrumentation through advanced technology. TruMatch Personalized Solutions is based on the proven philosophy of mechanical alignment. Instruments that match the natural anatomy of your patient. Individually shaped to fit securely to the bone. Predetermined key surgical cuts - based on the patient's mechanical alignment. Our rigorous approach to technological innovation means you can have confidence in offering a knee treatment that is right for you, and your patient. The TruMatch Solutions program from DePuy Orthopaedics brings a new level of personalized Total Knee Replacement surgery to your OR, allowing you to work with femoral and tibial cutting guides individually prepared to match the alignment criteria and actual bone surfaces of each patient. The design software takes into account your own surgical preferences. With TruMatch Solutions, you are able to provide a knee treatment designed around the individual needs of your patients.

5 Efficiency Reduced surgical steps Fewer standard instruments needed Fewer instrument cases to resterilize Facilitates faster OR turnover Function Elimination of up to nine steps from the surgical workflow Eliminates the need, and assembly, of the femoral IM rod guide, sizing guide and the tibial resection guide Based on the patient s mechanical alignment Wear Resistance 3D plan of the whole leg structure Facilitates proper implant placement and alignment, a key factor in reducing polyethylene wear in total knee replacement Determination of distal femoral and proximal tibial resection levels, varus/valgus alignment, femoral rotation and tibial slope

7 Software that delivers your plan. Your patient's 3D anatomy data and your personal surgical preferences are used together to define the Patient Proposal. DePuy Orthopaedics takes this information and then creates a Patient Proposal based on mechanical alignment. The TruMatch Solutions website allows you to review, approve, change, re design or cancel any Patient Proposal at any stage of the process.

9 With a three-dimensional plan of the whole leg structure, the TruMatch Solutions team of engineers will model resection guides to provide mechanical alignment through the new total knee. These will determine distal femoral and proximal tibial resection levels, varus/valgus alignment, femoral rotation and tibial slope. Wear Resistance, a key factor in an implant s long-term success is, in addition to implant design, strongly driven by correct implant alignment. Proper alignment is enabled by a combination of surgical skill and precise instrumentation.

10 The seamless TruMatch Solutions process Patient Imaging Following an assessment and recommendation from the surgeon, the TruMatch Solutions process begins with a CT scan of the whole leg, from hip to ankle, per a defined TruMatch Solutions scanning protocol. The CT scan will be conducted at a certified imaging center (local to the surgeon) and will then be electronically forwarded to our TruMatch Solutions team. The team will confirm the quality of the scan and create a new patient record for later submission by the surgeon s office. Case Submission Through a simple web interface, the surgeon s office finalizes the pertinent case information and submits the order to the TruMatch Solutions design team. Immediately, the system will provide the delivery date of the finalized blocks. Surgery can be scheduled any time thereafter, up to six months. The case information will be collated with the surgeon s surgical preferences already recorded in the system. Together with the implant geometry, the TruMatch Solutions design team will prepare a customized patient proposal. Image Processing and Patient Proposal Utilizing proprietary software, the TruMatch Solutions design team will create a complete three dimensional model of the whole leg structure, which will be combined with the patient s information and the surgeon s surgical preferences to create a customized patient proposal. The patient proposal will include information such as distal femoral and proximal tibial resection levels, varus/valgus alignment, femoral rotation and tibial slope.

11 Patient Proposal Approval An will alert the surgeon when the case specific patient proposal is ready for his/her comment and approval. The surgeon is then able to visit a password protected area of the TruMatch Solutions website to make, if necessary, any revisions and approve the proposal. Instrument Preparation and Kit Consolidation Once the surgeon approves the details of the proposal, preparation of the customized patient instruments takes place within our dedicated manufacturing center. Individual patient name and data are etched on each, to confirm identification in the OR. Stainless steel guides within the RenShape plastic blocks are designed to minimize particle generation during cutting. Delivery and Surgery The TruMatch Solutions resection guides are delivered sterile. The guides are delivered on, or prior to, the stated delivery date communicated during the case submission step. Surgery can take place any time thereafter up to six months.
