How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Background: This article presents a mathematical justification for a new approach to arthroscopic stitching of the knee joint meniscus, based on a 3D computer model of the meniscus developed using the COMPASS-3D (APMFEM) program and AutodeskInventorPRO. The research with the patent RK No. 35413 dated 10.12.2021, titled "Method of arthroscopic stitching of the meniscus of the knee joint" builds upon the work of Yu.V. Labunsky. Methods: Mathematical analysis was performed to compare two methods of stitching the meniscus: the new oblique-vertical stitch and the classical vertical stitch. The contact area of the meniscus tissues in the area of the rupture was measured for both stitching methods. Results: The findings demonstrate that the new oblique-vertical stitch offers a 1.5 times larger contact area of the meniscus tissues in the area of the rupture, compared to the classical vertical stitch. Additionally, the new method provides a more significant grip on the radial and circular fibers of the meniscus, surpassing the capabilities of the classic seam. Conclusion: The results of this study can be utilized to develop practical recommendations for traumatologists regarding arthroscopic stitching of the meniscus in the knee joint. The new approach, supported by mathematical analysis and a 3D computer model, offers improved outcomes in terms of contact area and grip on the meniscus fibers, potentially leading to enhanced surgical techniques and patient outcomes.
