2017 Clinical Research Summary

VERASENSE Sensor-Assisted Total Knee Arthroplasty offers proven clinical and economic advantages for surgeons and hospitals.

This downloadable booklet highlights VERASENSETM data from a compilation of research performed through January 2018 either in collaboration with or independent from OrthoSensor, Inc. The content of this booklet is to be used for reference only. The summaries include clinical studies that have resulted in the following proven results from the use of VERASENSE in Sensor-Assisted Total Knee Arthroplasty:

  • 98% of balanced patients  report being satisfied to very satisfied 3 years post-op1
  • Significantly higher Forgotten Joint Scores compared to unbalanced patients2
  • VERASENSE patients require less PT and 67% fewer MUAs post-op2-4
  • Decreased the need for all-component revision by 88%, facilitating implant cost mitigation5
  • Almost 75% lower rate of soft tissue balance-related early revision TKA (<2 years) compared to national averages1,6-10


A multi-center randomized controlled trial proved that - without VERASENSE - TKAs are only balanced approximately 50% of the time

Details and references for the above clinical and economic advantages are available within the 2017 Clinical Research Summary.
