TO EVALUATE THE FUNCTIONAL OUTCOME IN PATIENTS WITH FLOATING KNEE WHO UNDERWENT MRI

Abstract

Background: The reported occurrence of Floating knee has historically been underestimated, but with the expanded utilization of MRI and arthroscopy, their frequency has shown an uptick. There is a pressing need to classify this complex injury pattern taking into consideration associated soft tissue injuries as well. Soft tissue injuries might go unnoticed during clinical examination due to tenderness and swelling, but can be visualized through immediate MRI scans. The study aimed to evaluate the functional outcome of patients of floating knee who underwent MRI for soft tissue injury. Methods: The study was conducted at a tertiary care centre from February 2021 to January 2024. The research involved 100 patients with floating knee injuries who underwent MRI assessments for soft tissue injuries. Follow-ups were conducted at regular intervals: 1 month, 3 months, 6 months, 1 year, with a maximum follow-up duration of two and a half years. The outcome of floating knee injuries was assessed according to Karlstrom Olerud criteria. Results: Out of 100 patients of floating knee injuries who underwent MRI, seventy-two patients had meniscus/ ligament injury. 9 patients had patellar fractures with extensor mechanism rupture. As per the Karlstrom and Olerud criteria, there were 7 excellent, 46 good, 33 fair and 6 had poor outcome. 8 patients lost to follow up. Conclusion: Our aim is to initiate timely and accurate treatment by comprehensively addressing all associated injuries, including previously overlooked ligament damage around the knee. To enhance clinical outcomes, we advocate for a multidisciplinary approach involving various specialists in the care of these patients.
