Reason: s/p Right knee arthroscopy microfracture patella and MFC evaluate healing History: right knee pain MENISCI: There is intrasubstance signal within the medial meniscus indicating intrasubstance degeneration. The body of the medial meniscus also appears slightly extruded. There is perhaps mild fraying of the undersurface of the body of the medial meniscus but we see no findings suggestive of an unstable tear.ARTICULAR CARTILAGE AND BONE: There has been progression of the degeneration of the articular cartilage in the medial compartment with areas of full-thickness cartilage loss along the medial femoral condyle and medial tibial plateau just posterior to the anterior horn of the medial meniscus. There is edema-type signal in the underlying subchondral bone that is likely degenerative in etiology and is perhaps slightly less pronounced in the tibia on the current study than on the prior study but slightly more extensive in the medial femoral condyle. There is extensive partial thickness degeneration of the articular cartilage of the medial facet of the patella as well as small foci of full-thickness degeneration that appears similar to that seen on the prior study. A 1 cm disc-shaped focus of low signal intensity in the adjacent joint fluid may represent a displaced cartilage fragment. The articular cartilage of the lateral patellar facet appears unusually thickened, which likely reflects degeneration. There are cysts in the underlying subchondral bone. Note is made of a bipartite patella with cyst formation appearing similar to the prior study. The articular cartilage of the lateral compartment appears relatively spared.LIGAMENTS: The cruciate and collateral ligaments appear intact.EXTENSOR MECHANISM: The quadriceps and patellar tendons are intact. Patella alta is again noted, appearing similar to the prior study.ADDITIONAL
1. Progression of cartilage degeneration within the medial compartment as described above.2. Degeneration of the articular cartilage of the patella appears similar to that seen on the prior study although there may now be a displaced fragment in the adjacent joint fluid.3. Other findings as above.
