Knee pain MENISCI: There is blunting of the posterior horn of the medial meniscus likely relating to partial meniscectomy. There is linear branching signal within the posterior horn which appears less extensive than the prior examination and likely relates to degeneration as opposed to true tearing as it does not clearly extend to the articular surface. However there is some irregularity of the superior articular surface of the posterior horn and as a result a small tear cannot be excluded.There is blunting of the posterior horn of the lateral meniscus also likely relating to prior partial meniscectomy. There is globular increased signal within both the anterior and posterior horns of the meniscus which also appear less extensive than the prior examination and are likely reflective of degeneration as opposed to true tearing.ARTICULAR CARTILAGE AND BONE: Again seen is moderate diffuse articular cartilage loss of the medial compartment with areas of near full-thickness loss. Overall this appears similar to the prior exam. The articular cartilage of the lateral compartment is preserved. Heterogeneous signal intensity of the lateral patellar facet is noted without evidence of full-thickness defect.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Abnormal morphology and signal intensity of the lateral and medial menisci which likely reflects a combination of prior meniscectomy and degenerative change. There is irregularity of the articular surface of the posterior horn of the medial meniscus and a small tear in this region cannot be excluded.2. Moderate diffuse articular cartilage loss of the medial compartment, similar to the prior exam.
