What does all this mean 1. Cartilaginous thinning seen in the lateral facet of the patella. Lateral subluxation of the patella. Minor patellofemoral compartment osteoarthritis. Some subchondral cystic change and edema noted in the trochlea of the femur. 2. Small effusion. No meniscal injuries. Fluid seen about the medial collateral ligament is most likely due to the accompanying joint effusion, although I cannot rule out a low-grade proximal MCL sprain. The cruciate ligaments are intact. There are no fractures. 3. Trace cartilaginous fissuring of the lateral tibial plateau noted.
