Male, 39 years old. Knee instability MENISCI: There is complex tearing of the posterior horn of the medial meniscus associated with an intrameniscal cyst. When compared to the previous study, the intrameniscal cyst appears much more conspicuous. The anterior horn of the medial meniscus and the lateral meniscus are intact.ARTICULAR CARTILAGE AND BONE: A broad-based exostosis extending posteriorly from the proximal tibia is again noted, with normal bone marrow signal characteristics. The previously described small cartilage cap is not included in the field-of-view of this study. Remaining bony and articular cartilage is within normal limits, without bone marrow signal abnormality or focal cartilage defect.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.Complex tear of the posterior horn of the medial meniscus with an associated intrameniscal cyst.2.Benign-appearing exostosis extending from the posterior tibia is not significantly changed.
