“…The manifestations of the partial MPFL tear were defined as thickening and irregularity of the contour, including discontinuity of normal fibres and intra-ligamentous or extensive peri-ligamentous edema. The manifestations of the complete MPFL tear were defined as fibres in the expected region of the MPFL being completely discontinuous or appearing absent, with extensive surrounding edema (13) .…”

“…The partial or complete disruption of the MPFL was evaluated in three locations: at its patellar insertion (PAT), its mid-substance (MID) and its femoral attachment (FEM), including avulsiontype fracture at PAT or femoral origin. Injuries occurred simultaneously in more than one location of the MPFL were classified as combined injury (13) . This study aimed to evaluate the role of MRI in the detection of predisposing factors that may contribute to the development of patello-femoral instability.…”

Background: Patello-femoral stability is principally influenced by anatomic factors. Understanding the anatomy and biomechanics of the patello-femoral joint provides insight on the etiology and management of patellar instability. Magnetic resonance imaging (MRI) has emerged as an auxiliary method for investigating patello-femoral instability, particularly for detecting osteochondral lesions and for evaluating the medial patello-femoral ligament (MPFL). Objective: descriptive study including analysis of MRI knee done for patients with patellar instability suspected clinically with or without history of trauma. Patients and Methods: thirty patients were included in this study, all with suspicious patellar instability from Ain-Shams University, orthopedic clinic and other private clinics. A cross-sectional study was held where all the patients underwent MRI routine knee protocol. MRI knee images were interpreted for identification of different pathologies contributing to patellar instability. Results: sixty percent of the patients included in our study had MPFL injury, 43% showed patella alta, 83% showed trochlear dysplasia (by different measurements) and 43% showed lateral displacement of TT. Conclusion: MRI the modality of choice in diagnosing different pathologies of patellar instability, for its value in assessing soft tissue structures, detailed imaging of the cartilage and applying all measurement required.

A 20-year-old National Serviceman presented with six weeks of left anterior knee pain and swelling after training for his individual physical fitness test. The pain was predominantly over the lateral aspect of his patella and was exacerbated by running and squatting for prolonged periods. There was also occasional clicking in the knee and the sensation of instability.Physical examination revealed tenderness over the lateral joint line and lateral patellar edge. Although there was full range of movement of the knee, pain was elicited at extreme flexion. Patellar grind test and lateral McMurray's test were positive. What do the radiograph (Fig. 1) and subsequent magnetic resonance (MR) images (Fig. 2) of the knee show? What is the diagnosis?
