VERASENSE Sensor-Assisted Total Knee Replacement

VERASENSE™, a sensor-assisted wireless orthopaedic sensor used during total knee replacement (TKR), enables surgeons to make informed decisions on proper soft tissue balance and implant position - two factors that can improve patient outcomes.1,2

Benefits of Sensor-Assisted TKR
Patients whose knees were balanced with the use of VERASENSE Sensor-Assisted TKR have shown statistically significant improvements over patients whose knees were left unbalanced. Patients whose surgeon uses VERASENSE sensor-assisted technology during total knee replacement may experience:

  • Less Pain
  • Quicker return to normal activity
  • Improved knee function
  • Higher patient-reported satisfaction levels1,2

How Does VERASENSE Work?
This cost-effective disposable sensor is similar to technology used in smartphones and gaming applications. VERASENSE provides your surgeon with real-time data during surgery about your knee, including soft tissue balance and dynamic implant positioning. Lack of proper balance may result in premature implant failure and the need for revision surgery in the future. 3-6

During your TKR procedure, Dr. Gallivan uses the sensor to replace the standard tibial trial spacer. As he takes the knee through a full range of motion, the sensor sends data wirelessly to a monitor in the operating room, which provides him with information on compartmental loads within your knee. While TKR is a common procedure, surgeons previously had to rely on their experience to position and balance the implant effectively. With the use of the the real-time data from the sensor, VERASENSE aids in your surgeon’s decision-making about soft tissue adjustments and implant position, with the goal of resulting in a better balanced knee.

VERASENSE does not change surgical workflow or a surgeon’s decision on which implant design would be best for you. The procedure is the same, but with the use of this sensor device, surgeons can improve the balance and stability of your knee, allowing for improved patient outcomes when compared to a traditional TKR and the potential for a longer lifespan of your knee implant. 1-6
