Knee pain MENISCI: There is complex branching signal and abnormal morphology of the anterior horn of the lateral meniscus concerning for tear. The medial meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is increased marrow signal within the medial femoral condyle. A small amount of degenerative signal abnormality is seen within the tibial plateau underlying the lateral meniscus. The articular cartilage of the patellofemoral and medial compartment is intact. A full-thickness defect of the articular cartilage of the lateral femoral condyle is noted measuring approximately 1.5 cm in length. The articular cartilage of the remaining compartment is preserved. Small partial-thickness defects of the articular cartilage of the medial patellar facet are noted. Note is also made of a multipartite patella.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Abnormal signal within the anterior horn of the lateral meniscus which may reflect some tearing.2. Full-thickness cartilage defect of the medial femoral condyle superimposed upon mild diffuse thinning of the medial compartment.3. Edema within Hoffa's fat pad which may reflect a component of patellar impingement.4. Small marrow contusion of the medial femoral condyle.
