Popliteal artery aneurysms representing 80% of peripheral artery aneurysms rarely rupture (a reported incidence of 0.1-2.8 %) and second commonest in frequency after aorto-iliac aneurysms. They usually present with pain, swelling, occlusion or distal embolisation and can cause diagnostic difficulties. We report a 78 year old man who was previously admitted to hospital with a pulmonary embolus s...

Here, we describe a popliteal mass that was initially misdiagnosed as a simple popliteal cyst, which finally turned out to be osteochondrolipoma. A 63-year-old housewife presented with sustained knee pain in association with a palpable mass on the popliteal fossa. The mass was in the posteromedial area and soft, non-tender, non-movable in the posteromedial area. Using plain radiography, the mas...

Pseudoaneurysms of the popliteal artery are a rare clinical entity, accounting for <4% of all popliteal aneurysms. Accurate diagnosis and effective intervention is required to prevent potentially limb-threatening complications. We present the case of a 37-year-old man with acute limb ischaemia due to distal calf vessel thrombosis secondary to a popliteal pseudoaneurysm that was managed with cov...

BACKGROUND The purpose of this study was to evaluate the efficacy of arthroscopic knee cavity internal drainage and cyst cavity debridement operation of popliteal cyst in knee osteoarthritis patients. METHODS From August 2007 to March 2013, 58 knee osteoarthritis patients with popliteal cyst were treated with arthroscopic knee cavity internal drainage through posteromedial portal and poplitea...

For the differential diagnosis of popliteal phymas, popliteal artery aneurysms are evaluated. They are frequent among peripheral aneurysms. However, diagnosis is difficult in some patients because clinical symptoms vary. We report 2 patients who consulted our hospital for popliteal phymas. In these patients, surgery was performed via a posterior approach. In 1 patient, reconstruction was conduc...

Popliteal artery aneurysms (PAAs) are rare in general population but represent the second most common peripheral arterial aneurysms following those located in the aortoiliac segment. They usually affect men over 60 years old with established cardiovascular disease caused by atherosclerosis. Other more unusual conditions such as trauma, congenital popliteal aneurysm, mycotic aneurysm, inflammato...

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...
