Sensor-assisted total knee arthroplasty: A narrative review

Abstract

Wireless intraoperative load sensors have been used to improve the quality of soft-tissue balancing during total knee arthroplasty (TKA). Recent studies using the sensors have demonstrated reductions in gap imbalance, as well as early improvement of patient-reported clinical outcomes and low rates of arthrofibrosis. However, well-designed prospective studies are needed to determine whether the application of the sensor technology for TKA will have clinical benefits and improve the survival of prosthesis. Knowl-edge of the load-sensing technology (advantages and disadvantages, potential pitfalls, and future prediction) is crucial to apply this new TKA technique successfully. Herein, we conduct a narrative review of previous studies on this technique. Keywords: Knee, Arthroplasty, Computer-assisted surgery, Sensor, Load.
