Sensor-Assisted Total Knee Replacement
VERASENSETM SENSOR-ASSISTED TOTAL KNEE REPLACEMENT
VERASENSETM, a wireless orthopaedic sensor device used during primary and revision total knee replacement (TKR), enables surgeons to make evidence-based decisions on soft tissue balance and implant position - two factors that can improve patient outcomes. 1,2
How VERASENSETM Works
The disposable sensor device leverages technology similar to those used in smartphones and gaming applications. TKR is a common procedure, but before VERASENSE, surgeons generally relied solely on their “best judgment” in determining what “felt” like a balanced and stable knee.
During your TKR procedure, your surgeon uses VERASENSE to replace the standard tibial trial spacer. As the knee is taken through a full range of motion, the sensor sends data wirelessly to a monitor in the operating room, which provides information on compartmental loads within your knee. 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. Improper soft tissue balance and implant position may result in premature implant failure and the need for revision surgery in the future. 3-6
Benefits of Sensor-Assisted TKR
Patients whose knees were balanced through 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
- Improved patient satisfaction1,2
Knee instability is a leading cause of patient dissatisfaction after total knee replacement surgery.2,7 In a multi-center study, use of VERASENSE has been shown to reduce post-op pain and improve activity and patient satisfaction scores with statistical significance. In fact, 97% of patients whose knees were balanced using VERASENSE reported they were satisfied to very satisfied at one and two years following their total knee replacement. This compares favorably to peer-reviewed publications that show an average of 81% patient satisfaction after a total knee replacement.1,2 That’s a 16% improvement in patient satisfaction for balanced knees; the first significant-notable increase of patient-reported satisfaction in over 30 years.
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 the intraoperative data from this sensor device, surgeons aim to 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
