CONCLUSION: Both bone marrow edema and joint effusions existed with a peak occurrence in stage III disease. Bone marrow edema seems to have a stronger association with pain than does joint effusion in osteonecrosis of the femoral head.

Knee effusions may be the result of trauma, overuse or systemic disease. An understanding of knee pathoanatomy is an invaluable part of making the correct diagnosis and formulating a treatment plan. Taking a thorough medical history is the key component of the evaluation. The most common traumatic causes of knee...

A 19-year-old man with a complete cervical spinal cord injury was found to have bilateral hip effusions. Joint aspiration yielded a right sterile hydroarthrosis and a left sterile hemarthrosis.
CONCLUSION: This case indicates that hip effusion may be a similar, less-common occurrence than knee effusion in patients with spinal cord...

Intermittent hydrarthrosis is a condition of unknown aetiology characterized by transient joint effusions which recur at regular intervals; one or both knee-joints are usually affected, but occasionally other joints such as the hip, ankle, or elbow are involved

REVIEW of the American literature since 1941 reveals no reported cases of intermittent hydrarthrosis, a condition which was first reported by Perrin in 1845, and apparently again by the same author in 1878. Relatively few cases have been reported since then, apparently only 120 in all. Two additional cases are...

Clinical evaluation, radiographs, and sonograms together determined the need for US-guided aspiration. US-guided aspiration allowed selection of only those with septic arthritis for operative drainage and shortened that procedure. Negative sonograms allow exclusion of septic arthritis but not osteomyelitis.

More than 200 instances of periodic synoviosis have been recorded. It is related to periodic oedema (hereditary angioedema). Various autonomic disturbances accompany episodes. Confusion with rheumatoid arthritis persists. Theoretically an inherent rhythm or feedback mechanism operates as the cause.

Intermittent hydrarthrosis (IH) is a very uncommon condition characterized by episodic attacks of synovitis, usually in the large joints and most commonly the knees. The features which distinguish it from other periodic syndromes, such as palindromic rheumatism, are the predictable periodicity of the attacks, with one or two episodes per...

Syphilitic effusions of the joints is associated with the original description by Clutton. 3 cases of "Clutton's Joints" are described.

The teardrop sign, which can be seen on the standard lateral radiograph of the ankle in the neutral position, is useful in diagnosing ankle effusions of 5 mL or larger.

Pulse therapy with high doses of corticosteroids, although generally well tolerated, is associated with a variety of side effects, sometimes life threatening but, more often, mild. Among these, joint manifestations are only rarely encountered. Patients sometimes feel transient arthralgias, but the development of synovial effusion is exceptionally reported.
We described the...

Traditionally, joint aspiration has been performed using only external anatomic landmarks ("blind" aspiration) or fluoroscopic guidance. We illustrate the technique and role of joint aspiration of the shoulder, elbow, hip, knee, and ankle with sonographic guidance. Sonographic evaluation and guidance of aspiration offers several advantages over the traditional approaches. The...
