Abstract
OBJECTIVE: Evaluate the correlation between magnetic resonance imaging, clinical examination and intraoperative identification of posterolateral corner injuries of the knee. METHODS: We compared the findings of physical examination under anesthesia and intraoperative findings as the gold standard for the posterolateral corner injury with the reports of the MRIs of patients who underwent reconstruction of the posterolateral corner. Thus, we evaluated the use of MRI for the diagnosis of lesions. RESULTS: We found a sensitivity of 100% in lesions of the anterior cruciate ligament (ACL), 86.96% in lesions of the posterior cruciate ligament (PCL), 57.58% in lesions of the lateral collateral ligament (LCL) and 24.24 % in tendon injuries of the popliteal muscle (PMT). CONCLUSION: Posterolateral corner injury is difficult to visualize and interpret; therefore, MRI imaging should not be used alone for diagnosis.
