Reason: hx of R patellar dislocations, please measure TTTG, assess MPFL, etc History: same MENISCI: The medial and lateral meniscus appear intactARTICULAR CARTILAGE AND BONE: There is partial-thickness articular cartilage degeneration and superficial fraying along the lateral facet and median eminence of the patella. There is bone marrow signal abnormality within the medial aspect of the patella and lateral aspect of the lateral femoral condyle indicating prior transient lateral dislocation of the patella. There is a subcentimeter focus of fluid signal intensity within the medial and posterior aspect of the distal femoral metaphysis likely representing a benign enchondroma.LIGAMENTS: The cruciate and collateral ligaments appear intact. There is increased signal abnormality about the proximal and mid substance fibers of the medial retinaculum raising the possibility of a partial thickness tear, although the medial retinaculum is poorly visualized on this examination due to lack of axial T2 non fat saturated images.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
Findings indicating prior lateral transient dislocation of the patella with probable partial thickness tearing of the proximal/mid substance fibers of the medial patellofemoral ligament. Patella alta can be seen in patellofemoral instability.
