55-year-old male with right knee pain persisting for greater than 6 weeks. MENISCI: There is globular increased signal abnormality within the posterior horn of the medial meniscus consistent with intrasubstance degeneration. The medial meniscus appears intact. There is increased signal abnormality within the body of the lateral meniscus which extends to the tibial and femoral articular surfaces consistent with a radial tear.ARTICULAR CARTILAGE AND BONE: There is near full-thickness articular cartilage degeneration along the weightbearing portion of the lateral femoral condyle above and anterior to the posterior horn of the meniscus. There is a small serpentine area of increased signal abnormality within the superior patella, centrally, and along the lateral facet, consistent with a bone infarct.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. There is thickening with intermediate signal abnormality within the patellar tendon indicating moderate tendinosis.ADDITIONAL
.1. Small bone infarct of the patella as described above.2. Radial tear of the lateral meniscus.3. Findings consistent with moderate patellar tendinosis.4. Small joint effusion.
