Reason: Assess for medial meniscus tear; possible chondromalacia; PLEASE MEASURE TT-TG History: Medial joint line tenderness; h/o MPFL recon, chondroplasty and microfracture of PF compartment MENISCI: The medial and lateral meniscus appear intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness articular cartilage signal abnormality along the lateral facet of the femoral trochlea with underlying subchondral signal abnormality which may represent a combination of degeneration and postsurgical change from prior microfracture. No full-thickness defects are identified. There is linear decreased T2 signal abnormality along the medial facet of the femoral trochlea likely representing a full-thickness articular cartilage fissure with underlying degenerative subchondral signal abnormality. There is partial-thickness articular cartilage degeneration and thinning along the lateral facet of the patella.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. The Insall Salvati ratio is within normal limits. There is increased intermediate signal intensity within the patellar tendon indicating a mild tendinosis. There is thickening of the medial retinaculum which may represent postsurgical change, however, the retinaculum appears intact.ADDITIONAL
Postsurgical changes of prior MPFL reconstruction. Articular cartilage degeneration and postsurgical change of prior microfracture as well as articular cartilage fissuring affecting the patellofemoral articulation. Elevated tibial tubercle to trochlear groove distance with reference measurement provided above.
