Knee arthroplasty assisted by augmented reality: Case report

AR- Assited Knee Arthroplasty

Abstract

Background: Total knee arthroplasty (TKA) is a widely used procedure to treat advanced osteoarthritis, providing pain relief and functional improvement. However, the long-term success of the surgery depends on the precision in the positioning of the prosthetic components and the proper alignment of the operated limb. Objective: Describe the case of a 52-year-old patient, diagnosed with advanced gonarthrosis, who underwent TKA with the aid of augmented reality (AR). The patient had a history of hypertension, grade I obesity, and complaints of chronic pain in the right knee, with functional limitation and claudication. Method: The procedure was performed using prosthetic implants from the brand MicroPort Advanced®, with a navigation system assisted by AR, aiming for greater precision in correcting the mechanical axis and better adaptation of the components. Results: The surgery proceeded without complications, with a satisfactory postoperative evolution, including rapid functional recovery and significant symptom relief. Conclusion: The use of AR can offer significant advantages in surgical precision and functional outcomes, representing a promising alternative to optimize the longevity of implants in environments with limited infrastructure.
