VERASENSE SENSOR-ASSISTED TOTAL KNEE ARTHOPLASTY

Quantify Soft Tissue Balance and Customize Implant Position

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.1-4

VERASENSE enables surgeons to quantify ligament balance and customize implant position by giving them real-time, evidence-based data during primary and revision total knee arthroplasty (TKA). This disposable, intelligent device delivers data wirelessly to an intra-operative monitor that enables surgeons to make informed decisions regarding implant position and soft-tissue releases to improve knee balance and stability through the range of motion. This monitor – the LinkStation MINI – displays intraoperative data on a high definition tablet screen that occupies minimal space in the OR.

How Verasense Technology Works

Historically, surgeons have applied subjective feel and judgment when determining whether or not the knee is balance during TKA. The traditional techniques used by surgeons to determine the state of balance of the knee during surgery did not make use of quantified load data, nor did they have the ability to judge balance dynamically throughout the range of motion, including mid-flexion.

When using the VERASENSE sensor device in TKA, the surgeon performs the surgery in their usual way – the use of the sensor technology does not change the surgeon’s workflow in the operating room. Once the surgeon has employed his or her usual techniques and feels the knee is balanced, the operating room staff activates the sensor using the magnet on the LinkStation MINI. The surgeon then places VERASENSE into the tibial tray and examines the mediolateral loading values and contact point rotation* at 10°, 45° and 90° of flexion. Based on this real-time data, the surgeon makes adjustments to arrive at a better balanced knee. The current definition of balance, as applied to various knee designs, is a load differential between the medial and lateral compartments of ≤ 15 lbf through the range of motion.23,24,26
