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 patientreported 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. Knowledge 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.
