Reason: eval for recurrence History: GCT right knee MENISCI: Minimal high signal intensity within the medial and lateral menisci likely reflects intrasubstance degeneration. There is no discrete meniscal tear. ARTICULAR CARTILAGE AND BONE: There is moderate degeneration of the articular cartilage of the patella, particularly along the medial facet which appears similar to that seen on the prior study. Articular cartilage degeneration along the lateral tibial plateau also appears similar to that seen on prior study. There is subjective thinning of the articular cartilage of the medial tibiofemoral compartment, which also appears unchanged. The bone marrow signal intensity is within normal limits. LIGAMENTS: The ligaments appear intact.EXTENSOR MECHANISM: The quadriceps and patellar tendons appear intact. Again seen is metallic susceptibility artifact in the anteromedial subcutaneous fat of the knee with band-like low signal intensity medial to the patellar tendon likely representing scarring and appearing similar to the prior study. ADDITIONAL
Mild synovitis, degeneration of the articular cartilage and surgical changes as described above without specific imaging features of tenosynovial giant cell tumor recurrence.
