We aimed to determine the FGA and influence of preoperative deformity on the FGA, based on the MR technique, in varus knee osteoarthritis.<br><strong>Methods:<\/strong> In 321 navigated TKAs, we released the soft tissues in extension. In 90\u0001 flexion, with the tensioner in situ, we calculated the FGA, the angle between the posterior femoral cut (planned 3\u0001 external rotation to the posterior condylar line, parallel to the surgical<br>transepicondylar axis, or perpendicular to the Whiteside line) and the proximal tibial resection plane.<br><strong>Results:<\/strong> The FGA values varied widely, and the risk of .2\u0001 and .3\u0001 FGA was present in at least 60% and 40% knees, respectively. These risks were high in knees with moderate and severe varus deformity.<br><strong>Conclusions:<\/strong> In varus knee osteoarthritis, the risk of FGA (based on the MR technique) was high, especially when the deformity was moderate to severe. Caution is required in MR TKA, and surgeons must consider safer alternatives (gap balancing or hybrid technique) to<br>achieve a symmetrical flexion gap in these knees.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"330\" src=\"https:\/\/kneeworld.in\/blogs\/wp-content\/uploads\/2024\/02\/Original-1-1024x330.jpeg\" alt=\"\" class=\"wp-image-117\" srcset=\"https:\/\/kneeworld.in\/blogs\/wp-content\/uploads\/2024\/02\/Original-1-1024x330.jpeg 1024w, https:\/\/kneeworld.in\/blogs\/wp-content\/uploads\/2024\/02\/Original-1-300x97.jpeg 300w, https:\/\/kneeworld.in\/blogs\/wp-content\/uploads\/2024\/02\/Original-1-768x247.jpeg 768w, https:\/\/kneeworld.in\/blogs\/wp-content\/uploads\/2024\/02\/Original-1.jpeg 1336w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/kneeworld.in\/blogs\/PDF\/Dr Raj Kanna AAOS.pdf\" data-type=\"URL\" data-id=\"https:\/\/kneeworld.in\/blogs\/PDF\/Dr Raj Kanna AAOS.pdf\">Article Link<\/a><\/p>\n\n\n\n<p><strong>&#8220;Digital Knee Replacement&#8221;<\/strong> which is recognised by the<strong> American Academy of Orthopedic Surgeons,<\/strong> and published in their official journal, AAOS Global.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Influence of Preoperative Deformity on Flexion Gap Asymmetry in Measured Resection Technique: A Theoretical Study in Navigated Gap Balancing Total Knee Arthroplasties, Done for Varu Knee Osteoarthritis Raj Kanna, MS, DNBV.
