The clinical anatomy of several pain syndromes of the knee is herein discussed. These include the iliotibial tract syndrome, the anserine syndrome, bursitis of the medial collateral ligament, Baker's cyst, popliteus tendon tenosynovitis and bursitis of the deep infrapatellar bursa. These syndromes are reviewed in terms of the structures involved and their role in knee physiology. All of the dis...

Baker's cysts are one of the most common cystic lesions around the knee joint and mainly caused by fluid distension of the gastrocnemius-semimembranous bursa that is situated along the medial side of the popliteal fossa. Typically, a Baker's cyst extends along the intermuscular planes around the knee joint and may enlarge any direction. However, it is mostly located in the inferomedial or super...

Because of its subcutaneous location prepatellar bursitis is frequently complicated by an infection. Gram-positive organisms, primarily Staphylococcus aureus account for the majority of cases of septic bursitis. Local cutaneous trauma can lead to direct inoculation of the bursa with normal skin flora in patients with occupations, such as mechanics, carpenters and farmers. A 71-yearold male was ...

The object of this study was to determine the mechanism of the production of beat knee and its relation to pathological findings. A clinical study was made among 598 coal-face workers at one large colliery: 579 were examined of whom 233 showed evidence of past or present beat knee. A considerable preponderance of non-inflammatory lesions, most commonly in the prepatellar bursa, was demonstrated...

Lipoma arborescens is a rare benign entity characterized by proliferation of villous fat tissue in subsynovial layer that usually affects the knee joint. We report a case of lipoma arborescens in bicipitoradial bursa of the elbow in a 44 year-old female patient. In spite of this rare location, radiographic findings by ultrasonography and magnetic resonance imaging made diagnosis possible.

A Baker’s (popliteal) cyst is a distention of the gastrocnemius–semimembranous bursa of the knee, which communicates with the posterior portion of the joint capsule. It usually appears in the popliteal fossa as a painless swelling. In adults it is nearly always secondary to pathological changes in the knee joint that cause an effusion. Occasionally the cyst becomes so large that it ruptures, sp...

Baker's cyst is a distension of the gastrocnemius-semimembranosus bursa of the knee, which communicates with the posterior portion of the joint capsule. Baker's cyst is commonly located in the inferomedial or superficial layers of the knee joint and rarely extends laterally or proximally. Complications of Baker's cysts are dissection, rupture, pseudothrombophlebitis, leg ischemia, nerve entrapm...

Background: Lung cancer ranks among the most common and most lethal malignancies worldwide. Once vascular or lymphatic invasions occur, metastatic dissemination to distant sites is common. Bone, liver, adrenals, and brain are the most frequent sites of the distant disease. In this study we present a case of squamous cell carcinoma of lung with metastasis of the left knee bursa.Case presentation...

The anatomy and function of the opening between the knee joint cavity and gastrocnemio-semimembranosus bursa was studied in 120 necropsy specimens of knee joints both by conventional knife dissection and by a newly modified technique of serial cryosectioning of undecalcified joints frozen at various angles of flexion. The communication invariably took the shape of a transverse slit separating t...
