Posterior medial longitudinal scan of the knee

The patient lies prone with the knee in neutral position. The probe is placed longitudinally over the medial femoral condyle. The curvature of the femoral condyle with hypoechoic cartilage is identified and the transducer is moved inferiorly to centre on the joint.

Skin, subcutaneous fat, medial gastrocnemius muscle, semimembranosus tendon, femoral condyle and tibia are visualised. The probe is now moved inferiorly to assess for a Baker’s cyst.
