Alignment Comparison Between TruMatch™ Personalized Solutions and Conventional Total Knee Replacement Instrumentation

TruMatch™ Personalized Solutions is the brand name of DePuy Orthopaedics, Inc. custom patient instrumentation. TruMatch™ is a pair of custom-made cutting blocks that allow distal femoral and proximal tibial cuts to be made according to a predefined surgical plan. The inner surface of the femoral block is manufactured to match the geometry of the patient's distal femur. The inner surface of the tibial block is manufactured to match the patient's proximal tibia. The geometric data is obtained from a CT scan and a preoperative plan approved by the surgeon.

Total Knee Arthroplasty (PFC Sigma System) implanted using conventional instruments, not TruMatch™ instrumentation.
