Right knee instability MENISCI: There is no definite meniscal tear identified. A focal area of intermediate signal intensity is seen within the periphery of the posterior horn of the medial meniscus adjacent to the femoral articular cartilage. This is suspected to represent an interface with capsular structures rather than a true tear.ARTICULAR CARTILAGE AND BONE: There is a focal cleft of the articular cartilage of the lateral patellar facet which appears to extend through the majority of thickness of the cartilage. This is best appreciated on image 16 of series 3. LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons are intact.ADDITIONAL
Focal cleft of the articular cartilage of the patella with mild edema of the superolateral corner of Hoffa's fat pad, the combination of which may indicate patellar instability. The Insall Salvati ratio is borderline abnormal however the TT to TG distance is normal. If a more accurate TT to TG distance is desired, CT can be obtained.
