Experience of use of the individual cutting block «5 in 1» using total knee arthroplasty

Abstract

BACKGROUND: Total knee arthroplasty is the most progressively developing direction in the modern orthopaedic world. With the new visualization technologies, a whole new field of computer-assisted orthopaedic surgery has emerged. Generally, three groups can be distinguished in computer-assisted orthopedic surgery. The 1st group the use of individual resection blocks, templates or guides remains the most relevant today. However, the use of currently existing individual resection blocks, according to the literature, has contradictory results. CLINICAL CASES DESCRIPTION: This work presents the author's developed technique of a new preoperative 3D modeling for total knee arthroplasty using individual resection blocks. The paper presents a clinical case demonstrating the effectiveness of the new technique. CONCLUSION: The strategy CT+MRI, in our opinion, is the optimal solution not only for competent preoperative planning of total knee arthroplasty, but also for designing individual resection blocks. Our individual resection blocks allowed us to improve the accuracy of total knee arthroplasty.
