Robotically Assisted Total Knee Arthroplasty - Literature Review

Despite the evolution in implant design, surgical technique, rehabilitation and better medical training, a great number of patients are not satisfied with the final result of Total Knee Arthroplasty (TKA). The conventional TKA technique could result in a high number of outliers in limb alignment and are related to a high rate of residual symptoms. Robotically assisted (RA) surgery was introduced to improve these results. Recent studies showed this technique is associated to lower costs, better accuracy in implant placement and limb alignment, improvement in function and patient satisfaction. RA technique is also related to less blood loss, less bone resection and smaller aggression to soft tissues. Besides that, this brings better ergonomics to the surgeon with less caloric waste. In this way, by the benefits showed, the adhesion to the robotic surgery must be encouraged.
