Pain in knee popping. Check for ligamentous injury MENISCI: The lateral meniscus is intact and unremarkable. The medial meniscus however demonstrates pronounced globular signal and loss with mild extrusion of the body of the meniscus extending into the posterior horn. Relative preservation of the anterior horn/aspect. Although there is no definite distinct linear component, a somewhat more oblique tear through the body extending to the inferior articular surface is suggested. Both menisci remain well anchored posteriorly.ARTICULAR CARTILAGE AND BONE: Moderate osteophytic changes with small subchondral cysts and osteophytes involving both medial and lateral compartments, with underlying mild edema. Minimal thinning of the lateral compartment, however near complete cartilaginous loss in the medial compartment, specifically overlying the condylar surface with underlying changes. Or mild to moderate changes are also observed in the patellofemoral compartment with a small fissural shallow cleft observed in the lateral facet (image 22 series 1301).LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Medial meniscal tear and destruction with underlying moderate to marked osteoarthritic changes, as described.
