Abstract

Introduction: Total knee replacement (TKR) is the treatment of choice in the final stages of degenerative joint disease, and its survival depends largely on the alignment, positioning, and stability of the joint. This research aims to compare the mechanical axis of the lower limb measured by telemetry, after a computer navigation-assisted TKR vs. conventional techniques, performed by the same surgeon and using the same prosthesis. Secondly, to evaluate the degree of satisfaction of the patients submitted to this procedure and its possible variation between these two techniques.
Materials and Methods: Retrospective, comparative, observational, descriptive study of 200 patients undergoing TKR, divided into two groups: Group A (100 patients), with Columbus® prostheses placed with the OrthoPilot® navigation system; and Group B (100 patients), with the same prosthesis placed with the conventional technique. Postoperative telemetry was performed on all patients to determine and compare the results in both groups. Secondly, the degree of satisfaction with the procedure and body mass index (BMI)—and its possible relationship with the results—were compared.
Results: Computer navigation-assisted TKR obtained better outcomes with statistically significant differences both in the postoperative mechanical axis and in the degree of satisfaction with the procedure.
Conclusion: Computer navigation-assisted primary TKRs were shown in our study to be more accurate in achieving final limb alignment on a 0 ° +/- 3 ° limb mechanical axis.
