Popliteus tendon tenosynovitis * Commentary

Popliteus tendon tenosynovitis.

This case report highlights an unusual cause of anterolateral knee pain. The popliteus muscle arises from three origins--that is, the lateral femoral condyle, the fibula head, and the lateral meniscus--and inserts into the proximal tibia above the soleal line. It may be subjected to a number of pathologies including tenosynovitis, acute calcific tendonitis, rupture, and even avulsion. In this c...

Magnetic Resonance Imaging Double Popliteus Tendon Sign

The double popliteus tendon sign is seen on sagittal magnetic resonance imaging (MRI) of the knee as a low-signal-intensity band parallel to the popliteus tendon at the level of the popliteus hiatus. It is the result of a displaced complex flap tear of the lateral meniscus. This type of displaced meniscal tear can be easily missed on MRI, unless the clinician is aware of its existence and signi...

Isolated avulsion of the popliteus tendon.

We report four patients with a mean age of 17 years (14 to 22) with external rotation injuries of the knee in slight flexion. Radiographs showed a small fragment in the area of the lateral femoral condyle. At operation, the fragment, consisting of the femoral insertion of the popliteus, was anatomically reduced and fixed. At a mean follow-up of 35 months all the knees had an excellent function ...

Sonographically Guided Popliteus Tendon Sheath Injection

Objective. The purpose of this investigation was to describe two sonographically guided popliteus tendon sheath injection techniques and determine their accuracy in a cadaveric model. Methods. A single experienced operator completed 24 sonographically guided popliteus tendon sheath injections, 12 using a longitudinal approach and 12 using a transverse approach relative to the tendon. The inject...
