Instability and malalignment are among the leading causes of premature implant failure in TKA.1 VeraSense can help you address these challenges by enabling you to objectively determine if you have achieved a balanced knee. With VeraSense, you can Know more. Be sure. Multiple studies have been published that all show the same thing – a balanced knee with VeraSense is a better knee.2-4


Imbalance of soft tissues and improper position of the knee implant can result in pain, stiffness, limited range of motion and instability in the knee. VeraSense sensor technology is a single-use instrument that delivers evidence-based data wirelessly to an intraoperative monitor, enabling surgeons to perform real-time, quantified soft tissue balancing and implant positioning during total knee arthroplasty (TKA).

Key benefits

Reduce MUAs

Overall rate of MUA


VeraSense has been shown to mitigate 90-day post-op complications through soft-tissue balance. In one study, patients who received TKA balanced with VeraSense showed a 67% reduction in MUA rate compared to those who underwent standard manual TKA.2*

Improve Short Term Outcomes

Mean Score Change (pre-op to 6 months)
  Manual VeraSense P-value
KSS Pain 29 36 0.001
KSS Function 23 27 <0.001
KSS Total 52 63 <0.001
Oxford 13 17 0.025
Quantitative knee balance through VeraSense has demonstrated significantly improved patient outcomes during the early postoperative phase.3*,4 In one study, the use of VeraSense led to faster improvement in KSS and Oxford PROMs.3*

In a separate multicenter study, patients whose knees were balanced throughout the range of motion with VeraSense reported significantly higher KSS satisfaction scores compared to patients whose knees were unbalanced.4

Reduce Costs

Physical therapy visits
Adoption of VeraSense may lead to cost savings, primarily associated with the costs of postoperative physical therapy visits. In one study, reduction in physical therapy visits resulted in cost savings of $319 relative to pre-VeraSense adoption and $549 relative to the national average in the 90-day bundle.5*

* This study utilized a non-Stryker VeraSense variant in reaching its conclusions. Outcomes may vary when using a Stryker variant.

VeraSense clinical research summary

Clinical and economic benefits of quantified balance

A knee that is not correctly balanced during total knee arthroplasty may result in pain, stiffness, limited function and range of motion and instability for the patient following surgery.5-9 These patient-reported outcome measurements can influence patient satisfaction and quality of care metrics for reimbursement.

The use of VeraSense has shown statistically significant improvements in patient-reported outcome measurements and increase in physical therapy performance during early post-op recovery and rehabilitation for TKA.2-5 These improvements have translated to shorter treatments and lower overall costs in the complete TKA episode of care.5

How VeraSense works

The VeraSense trial, which replaces the standard Triathlon tibial insert trial, can be used during the trialing and final implantation stages of TKA. It utilizes proprietary sensor technology to provide you the following real-time data:

  • Dynamic medial and lateral compartmental loads, quantified in pounds-force (lbf)
  • The location of the center of load in each compartment**
  • Kinetic tracking of tibiofemoral articulation**

The VeraSense software displays this information on a tablet – the LinkStation MINI – via Bluetooth communication, allowing you to intraoperatively view and capture the compartmental loads at multiple degrees of flexion and assess joint kinetics throughout a range of motion.
