Total Knee Replacement Using Sensor Technology | OrthoSensor

Learn About Sensor-Assisted Knee Replacement with VERASENSE

Smart sensor technologies, like those used in cellphones and gaming devices, are changing the way we live our daily lives.  OrthoSensor is leading the way, leveraging the latest sensor technology to assist your surgeon in performing a successful knee replacement surgery.

Real-Time Data in Your Surgeon’s Hands

OrthoSensor has harnessed the latest breakthroughs in sensors, microelectronics and wireless communications to develop and manufacture one of the most advanced technology in knee replacement. This sensor device provides surgeons real-time data during surgery that may help you return to normal activities faster, improve your activity level and experience better knee function.28, 32 This knee replacement technology is transforming primary and revision total knee replacement around the world.

VERASENSE Sensor-Assisted Surgery

VERASENSE was developed by OrthoSensor® to assist surgeons with an unmet technical medical challenge of measuring compartmental loads to better balance soft tissues. This low-cost, single-use sensor temporarily replaces the standard plastic tibial trial spacer used during knee replacement surgery, providing surgeons immediate visual feedback during the surgery. This feedback, transmitted wirelessly by the sensor, gives surgeons information on soft tissue balance and implant position — two key factors for a successful knee implant.

While previously surgeons had to rely on their judgment and experience to balance the knee, VERASENSE is making soft tissue balance a more precise science. In the future, OrthoSensor will continue to deliver intelligent orthopaedic solutions, including implantables, for ongoing and remote monitoring of knee implants.

The Same Knee Replacement Surgery, But Better

VERASENSE doesn’t influence your surgeon’s decision regarding which type of implant design is best for you. VERASENSE doesn’t change the typical surgical flow. The procedure fundamentally stays the same, but with the help of VERASENSE, surgeons can make informed evidence-based decisions – instead of relying solely on feel or experience – to improve the position and balance of your knee implant through the range of motion.

VERASENSE Use in Revision Total Knee Replacement

Revision knee replacement can be necessary for various reasons. Sometimes, improper soft tissue balance of a patient’s original total knee replacement procedure – resulting in persistent pain, instability and stiffness – may be the cause.1-5  In cases where the total knee replacement “looks good, but feels bad,” your surgeon may be able to use VERASENSE to correct this imbalance and potentially replace fewer metal components than planned.
