Fracture Morphological Characteristics And Associated Soft-Tissue Injuries In Flexion Varus Tibial Plateau Fractures

Description

In this episode of AI Talks with Bone & Joint, Simon and Amy discuss a March 2026 study by T Ye and colleagues on flexion varus tibial plateau fractures. They explain why these injuries are challenging, describing them as the result of axial loading combined with varus force on a flexed knee, often leading to poor outcomes and high reoperation rates. The study used CT and MRI data to create 3D fracture maps and heat maps, analyzing 108 patients and classifying medial tibial plateau fracture patterns into three groups: posteromedial coronal split, entire medial condyle fragment, and comminuted medial condyle fragments. They also review the very high rate of associated soft-tissue injuries, including ACL avulsion fractures in about 85% of cases and lateral meniscus injuries in more than half of patients, with entrapment especially common in comminuted fractures. The hosts highlight that maximal depression depth on CT was the best predictor of lateral meniscus entrapment, with a cutoff of 18.4 mm showing strong sensitivity and specificity. The episode concludes by emphasizing the importance of assessing both bony and soft-tissue damage to improve preoperative planning and guide more tailored surgical treatment.
