52-year-old female with pain and swelling. An alternative knee coil was utilized for this examination, rather than the HD coil, presumably due to the patient's body habitus, resulting in suboptimal image quality.MENISCI: The body and posterior horn of the medial meniscus are attenuated which may represent postoperative changes of prior partial meniscectomy, chronic attritional tearing or a combination of both. There is also abnormal intermediate signal intensity within the body of the medial meniscus which extends to the tibial articular surface. We cannot determine if this represents a meniscal tear or residual degenerative signal subsequent to prior partial meniscectomy. No fluid signal intensity is identified within the meniscus to confirm a tear. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is thinning of the articular cartilage of the medial tibiofemoral compartment with additional small foci of near-full-thickness articular cartilage degeneration along the medial femoral condyle which have perhaps progressed slightly when compared to the prior examination.There is superficial degeneration of the articular cartilage of the lateral tibial plateau with degenerative signal abnormality in the underlying subchondral bone. There is also superficial degeneration of the articular cartilage of the patella, particularly along the medial facet. There is a small focus of signal abnormality in the distal femoral metaphysis which likely represents an enchondroma.LIGAMENTS: The cruciate and collateral ligaments appear intact.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Medial meniscus abnormalities which are presumably postoperative in etiology. There is intermediate signal intensity within the body of the medial meniscus which extends to the tibial articular surface which may represent residual mucoid degeneration of the body of the medial meniscus; however, we cannot exclude an undersurface tear of the meniscus. We see no fluid signal intensity entering the meniscus to confirm a tear.2. Articular cartilage degeneration, as described above, which has perhaps progressed slightly when compared to the prior study, particularly along the medial femoral condyle.
