PEAK PlasmaBlade 4.0 Versus Traditional Electrosurgery in Total Knee Replacement.

Total knee replacement is a surgical procedure performed to replace the weight-bearing surfaces of the knee joint. The goal of total knee replacement is to improve a patient's mobility by improving the function of the the knee joint. The PEAK PlasmaBlade® uses pulsed radiofrequency (RF) energy and a highly-insulated handpiece design to enable precision cutting and coagulation at the point of application. The PlasmaBlade has received FDA clearance for use in plastic, general, orthopedic, and ear, nose, and throat (ENT) surgery, and has demonstrated a significantly reduced thermal injury profile in incised tissue compared to traditional electrosurgical devices. It is hypothesized that this benefit may improve the post-operative outcome of patients undergoing total knee replacement.
