TruMatch™ Personalized Solutions
 |
TruMatch Solutions, only available with Sigma® Knee Replacements, use a three-dimensional computerized scan of your leg to create customized surgical guides that are designed to deliver a personalized solution based on your unique anatomy. DePuy Orthopaedics, Inc. developed TruMatch Solutions to help your surgeon achieve consistency in the placement and positioning of your knee replacement.
Positioning and alignment are crucial to the overall performance of your implant.1,2,3,4 Researchers have found that even a misalignment as slight as three degrees can lead to uneven wear, instability and increased risk of revision surgery following knee replacement.1 That's why precise positioning and placement play such an important role in the success of your implant.

How does the TruMatch Solution work?
DePuy Orthopaedics uses state-of-the-art software, along with your CT scan, to create a virtual 3-D model that shows the structure of your knee and the progression of your arthritis. DePuy Orthopaedics then works with your surgeon to develop customized instrumentation:
| Step 1 A CT scan is taken of your leg at your local hospital or image center. |
 |
Step 3 The structure of your knee is analyzed and your personalized guides are created. |
 |
|
| Step 2 The image is sent to DePuy Orthopaedics where a special team works with your surgeon to develop a 3-D model of your knee. |
 |
Step 4 Your guides are delivered to your surgeon the day of your surgery to help position and place your new knee implant. The guides are removed prior to your new knee being implanted. |

Important Safety Information
The performance of knee replacements depends on age, weight, activity level, and other factors. There are potential risks and recovery takes time. People with conditions limiting rehabilitation should not have this surgery. Only an orthopaedic surgeon can tell if knee replacement is right for you.
