Osteoarthritic changes of the left knee joint evidenced by narrowing of joint spaces, marginal osteophytosis of the articular surfaces, denudation of the articular cartilage and sub-chondral degenerative marrow changes of the lateral femoral and to less extent tibial condyles. Grade II degeneration of posterior horn of lateral meniscus and torn posterior horn of medial meniscus.
Chronic complete tear of the anterior cruciate ligament with the anterior inter-condylar notch showing a soft tissue signal eliciting central intermediate to high signal on T2WI and peripheral low T2WI signal. It is seen measuring 2.3 X 2.2 X 1.4 cm along its maximal axial and cranio-caudal dimensions.
Mild left knee joint effusion is noted with a distended gastrocnemius/semimembranosus bursa.
