Posteromedial knee friction syndrome

Posteromedial knee friction syndrome is a recently described cause of posteromedial knee pain in active young individuals. It is thought to be due to narrowing of the space between the posteromedial femoral condyle, sartorius and/or gracilis tendons.

Clinical presentation

Patients present with medial knee pain which is often clinically suspected to be due to a meniscal tear. 

Radiographic features

It is occult on radiographs and CT.

MRI

Focal area of high signal intensity on T2 or PD weighted fat saturated images (oedema) involving the soft tissue between the posteromedial femoral condyle (PMFC) and the sartorius and/or gracilis tendons. In severe cases, it is associated with bone marrow oedema of the PMFC.

In 27%, it is associated with patellar tendon lateral femoral condyle friction syndrome.
