There is a moderate reduction of the medial femorotibial compartment with marginal osteophytes from the peri-articular surface of femur and tibia. There is no fracture/ dislocation/ bone lesion. Soft tissue swelling is present at the medial joint line. There is no suprapatellar effusion.

The long-axis view of the medial side of the left knee shows joint space reduction, marginal osteophytes from femur-tibia, and extruded medial meniscus. The overlying medial collateral ligament is intact.
The less symptomatic contralateral side shows similar findings.
Case Discussion
The case shows medial meniscal extrusion with osteoarthritis.
