Video Summary

The speaker discusses imaging techniques for diagnosing patellofemoral instability and dislocation, focusing on radiographs, MRI, and CT. Key predisposing factors reviewed include patella alta, trochlear dysplasia, abnormal TTTG distance, and patellar tilt. Radiographs are emphasized as first-line, with specific views and measurements detailed. Trochlear dysplasia is highlighted as a critical factor, assessable via x-ray and MRI. The medial patellofemoral ligament's anatomy and injury patterns in dislocations are explained. MRI is crucial for evaluating cartilage lesions. Proper imaging technique is stressed to accurately identify and measure these factors, aiding diagnosis and management of patellofemoral instability.
