Sham Comparator: Group A TKA without VERASENSE
will consist of 250 consecutive patients who will undergo primary PCL-retaining or - sacrificing TKA without the use of VERASENSE to guide rotational alignment and balance.

Procedure: TKA without "Verasense"
TKA will be performed manually without the use of Verasense |
Active Comparator: Group B TKA with VERASENSE
will consist of 250 consecutive patients who will undergo primary PCL-retaining or - sacrificing TKA with the use of VERASENSE to guide rotational alignment and balance.

Device: TKA with "Verasense"
VERASENSE replaces the standard tibial trial inserts and is embedded with microelectronics and sensors to provide surgeons with real-time knee kinetic data. The data is wirelessly transmitted to a graphic display (VERASENSE Knee Application), allowing surgeons to quantify and assess soft tissue intercompartmental loads throughout the range of motion. The VERASENSE sensor is not an investigational device. OrthoSensor, Inc., received FDA 510K clearance in 2009. The indication for use is a tool for adjustment of the femoral knee implant to reduce instability from flexion gap asymmetry. The VERASENSE sensor is sterile and single patient use. |
