Benefits of VERASENSE Sensor-Assisted Knee Replacement

Increased Patient Satisfaction

Patients in a three-year multicenter study whose knees were balanced using VERASENSE showed 98% patient satisfaction. When compared to studies done within the same post-op interval, published literature shows that these patients whose knees were not balanced with VERASENSE only reported an 87% patient satisfaction.

Forgotten Joint Score

In a multicenter blinded control trial, patients whose knees were balanced using VERASENSE reported being less aware of their knee replacement compared to unbalanced patients at six weeks, six months and one year after surgery.

Other Patient-Reported Outcome Measures

In addition to increased patient satisfaction, VERASENSE patients have also reported having:

  • Less pain
  • Quicker return to usual activities
  • Improved knee function
  • Increased activity levels

Improved Physical Therapy After Surgery

A study performed by the same surgeon comparing 57 VERASENSE TKR patients to 57 manual TKR patients showed that:

  • VERASENSE patients experienced significantly higher Clinic Range of Motion (ROM)
  • VERASENSE patients had significantly higher improvement in Clinic ROM from the measurements before surgery.
