Knee dislocations are a relatively uncommon occurrence in the trauma patient. However, sequelae may be disastrous if this condition and its complications are not recognized early. Perhaps the most significant complication is popliteal artery injury, occurring in 10-32% of knee dislocations (1). This frequent complication can result in amputation (3,6,16). Popliteal artery injury from knee dislo...

Background: Popliteal cysts are common and present as asymptomatic lumps in the medial popliteal fossa. Some have complex internal characteristics such as septa and loose-bodies. However, not all are popliteal cysts and can be aggressive. These lesions need to be differentiated by the absence of the communicating neck with the joint on ultrasound. Presence of Doppler flow of non-communicating c...

Popliteal cyst (Baker’s cyst) was first described by Adams in 1840, popularized by Baker in 1877, and was theorized as an enlarged gastrocnemiussemimembranosus bursa that communicated with the knee and trapped synovial fluid.1 Numerous bursa are located in the popliteal space between the knee ligaments, hamstring tendons, gastrocnemius muscle, and collateral ligaments. The two proposed etiologi...

Popliteal artery pseudoaneurysm is uncommon. They usually result from penetrating or blunt trauma, arterial reconstructive surgery, invasive diagnostic or surgical orthopedic procedures. They can cause arterial thrombosis and limb ischeamia. We report a 53 year old Chinese gentleman with popliteal artery pseudoaneurysm who presented with right lower limb numbness and paralysis in toes extension...

In regard to arthroscopic treatment of popliteal cysts, we explored the refuted pathology for popliteal cysts proposed by others. Here we introduce an arthroscopic technique using posterior portals to treat a popliteal cyst based on our observation that the opening of the cyst in the joint is a slit-like structure in the posterior wall of the capsule. By disrupting this slit-like structure with...

[Purpose] Friction massage (friction) of the popliteal fossa is provided for the purpose of relieving pain related to circulatory disorders by improving venous flow in the lower legs. The purpose of this study is to verify the effects of enhancing the venous flow based on measuring the blood flow velocity of the popliteal vein before and after providing friction to the patients. [Subjects and M...

The popliteal pterygium syndrome is a highly characteristic congenital malformation syndrome affecting the face, limbs, and genitalia. Gorlin et all 2 coined the term 'popliteal pterygium syndrome' on the basis of the most unusual anomaly, the popliteal web. In some publications the names of Fevre and Languepin3 are used as an eponym. A more descriptive term suggested for the condition, on the ...

Although rare, popliteal vein aneurysms can lead to pulmonary emboli, which can be fatal. We present a case of a popliteal vein aneurysm in a 39-year-old female who presented with her third episode of pulmonary embolism despite being on anticoagulants. Computed Tomography Venogram demonstrated a large Popliteal Vein Aneurysm measuring 71×36×77 mm which was surgically repaired. According to the ...

The article describes a case in which a popliteal cyst was identified presenting as a mass on the anterior aspect of theright tibia. This occurred as a result of polyethylene wear debris from previous total knee arthroplasty. Although alternativediagnoses for an anterior tibial mass are more likely, a popliteal cyst must be considered, particularly if the patient has ahistory of total knee arth...
