  • Descrição: To assess the diagnostic accuracy of magnetic resonance imaging (MRI) in evaluating patello-femoral instability as a cause of anterior knee pain (AKP) and its predisposing factors. 55 knees of 50 adult patients below 40 years complaining of AKP underwent MRI between February 2013 and February 2015. The patients were analyzed prospectively for the presence of bone, hyaline cartilage and soft-tissue abnormalities, as well as anatomic variants that may contribute to patello-femoral maltracking or impingement abnormalities. Our results were compared to those of the arthroscopic and mini open exploration procedures. In the 55 knees analyzed for patello-femoral instability cartilaginous injuries were found in 58%, with an MRI sensitivity of 88%, disruption of the medial patello-femoral ligament (MPFL) in 31% with an MRI sensitivity 84%, joint morphology abnormalities in 74.5% of patients, bone edema in 27% of patients and Hoffa’s fat pad edema in...
