Arm Groups

ArmDescriptionAssigned Intervention
Active Comparator
NOVABLOC Stimulation
Subjects will receive NOVABLOC stimulation prior to their TKA
  • Device: Percutaneous radiofrequency electrical nerve stimulation
    Percutaneous radiofrequency electrical nerve stimulation will be applied to the femoral and sciatic nerves prior to TKA.
Sham Comparator
Sham Stimulation
Subject will receive sham non-therapeutic stimulation
  • Device: Non-therapeutic stimulation
    Electrical square wave stimulation performed to mimic the duration of the active arm and mimic the procedure for blinding purposes.
