Abstract

The next generational leap in computer navigation will hopefully aid surgeons in personalizing surgical techniques to patients' individual anatomical variables to optimize outcomes. To effectively use the information obtained in the operating room, a multitude of kinematic variables must be conveyed to the orthopedic surgeon in a usable and coherent manner. This study used an intraoperative navigation system to record passive knee kinematics after a total knee arthroplastyperformed. The clinical measures were taken via research software with the ability to record kinematic data in 10-second intervals. The data from 10 consecutive clinical cases were averaged, and the translation (anterior/posterior) and rotation (internal/external) were recorded and compared from 0° to 100° of flexion to allow for comparison with the previously recorded computer model. Model and clinical curves compared favorably, with less than 1° rotational and 1.5-mm differences, on average. The comparison of information and analyses were reviewed to indicate how they might be interpreted in the operating room for future use during surgery to allow a more personalized approach to improving functional outcomes after total knee arthroplasty.
