Introduction: The knee joint has several tendinous and ligamentous structures, which makes it particularly vulnerable to complex trauma injuries. The aim of our study is to present in detail the general mechanisms of avulsion fractures and major findings in magnetic resonance study, with emphasis on the most common injuries. Materials and Methods: There were evaluated by 1.5 Tesla magnetic ressonance study, between January 2011 and November 2012, 70 patients (57 males and 13 females) who developed severe knee injury, most during the practice of sport.

Discussion: A variety of avulsion fractures in the knee can occur during trauma, including capsuloligament avulsions like Segond fracture, reverse Segond fracture, avulsions of cruciate ligament and arcuate complex; tendon avulsions like avulsions of the femoral biceps, semimembranosus and quadriceps, and lastly, avulsions resulting from repetitive trauma, such as Sinding-Larsen-Johansson and Osgood-Schlatter traction osteochondritis. Conclusion: Although conventional radiography is usually the imaging modality performed at a first time, MRI is the ideal non-invasive method to assess the extent and severity of avulsion fractures of the knee, showing a significant impact on therapeutic management and prognosis.
