Reason: left knee pain for 1 year, minimal response to prior injections, eval for meniscal/tendon pathology; +medial McMurray History: as above. MENISCI: Extrusion of the medial meniscus into the medial gutter. Fraying on the undersurface of the anterior horn of the medial meniscus. Irregularity and small size of the posterior horn of the medial meniscus compatible with degenerative tearing. The lateral meniscus is intact. ARTICULAR CARTILAGE AND BONE: Severe osteoarthritis of the medial tibiofemoral compartment with marked thinning of the cartilage, near bone on bone apposition, osteophyte formation, and subchondral edema. Moderate osteoarthritis of the lateral tibiofemoral compartment with mild cartilage thinning. Severe osteoarthritis of the patellar compartment with complete cartilage loss along the lateral facet of the patella and marked thinning along the medial facet of the patella and osteophyte formation. No acute fracture or malalignment.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Degenerative tearing of the posterior horn of the medial meniscus. Extrusion of the medial meniscus into the medial gutter. 2.Severe tricompartmental osteoarthritis with complete cartilage loss involving the medial tibiofemoral and patellar compartments.3.Moderate size joint effusion.
