MRI signs include the "tail sign," which is seen with a narrow neck or pedicle connecting the intraneural cyst to the joint; denervation of the popliteus muscle and resulting fatty atrophy, i.
The most common overuse syndromes of the knee are iliotibial band friction syndrome, patellar tendinopathy, popliteus tendinopathy and pes anserine bursitis.
30) The function of the meniscofemoral ligament is to stabilize the lateral meniscus against the pull of the popliteus muscle.
From a musculoskeletal perspective, popliteus has been implicated in complaints of posterior knee pain that is exacerbated with activities such as crouching and either walking or running, downhill or downstairs.
Popliteus is described as a thin or flattened triangular shaped muscle.
1,3) The physical findings, however, are not specific for ITB syndrome, and the differential diagnosis includes a wide variety of disorders ranging from arthritic changes to the lateral compartment of the knee, LCL injury, popliteus or hamstring tendon strain, and/or meniscal injuries, as well as patellar subluxation/dislocation.
After orthopaedic evaluation and magnetic resonance imaging (MRI) were performed at an outside institution, he was diagnosed with a medial meniscal tear and strain of the popliteus tendon.
Review of the previously performed MRI revealed grade I signal change in the medial meniscus and marked thickening within the intrasubstance of the popliteus tendon.
The investigators hypothesized that secondary restraints, such as the LCL and popliteus, may provide additional restraints under posterior loading of the knee, but may also be at increased risk of injury.
7) The deep lamina of the third layer contains the popliteofibular ligament (PFL), arcuate ligament, and the popliteus muscle and tendon complex.
The femoral site of origin is posterior to the popliteus origin (8) and the fibular site of insertion is distal to the insertions of the arcuate and PFL.
In the deep posterior compartment lie the flexor digitorum longus, flexor hallicus longus, and proximally, the popliteus.
