patellar instability MENISCI: The medial lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage of the medial and lateral compartments is intact. There is signal heterogeneity and deep fissuring of the articular cartilage of the lateral patellar facet but otherwise patellofemoral compartment is also preserved. There is a small focus of increased signal within the inferior aspect of the lateral patellar facet but otherwise the marrow signal of the patella and femoral trochlea is normal.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons are intact.ADDITIONAL
Findings suggestive of remote patellar subluxation with chronic tearing of the MPFL, edema within Hoffa's fat pad, and heterogeneous signal/measuring of the underlying patellar cartilage. There is lateral patellar tilting and the TT to TG distance and Insall Salvati ratios are elevated although there is no evidence of trochlear dysplasia.
