Which characteristic is NOT associated with lipohemarthrosis?

Lipohemarthrosis is a condition that involves the presence of fat and blood within a joint space, typically following trauma. In this condition, the analysis of joint aspirate reveals several key characteristics.

The presence of globules in the fluid indicates the presence of fat, as lipohemarthrosis involves not only blood but also fat that leaks into the joint. The opaquely bloody appearance is due to the combination of the blood and fat, leading to a thick and turbid fluid rather than a clear one. Additionally, the oily and greasy consistency of the aspirated fluid is a hallmark of lipohemarthrosis, reflecting the emulsified fat mixed with the blood.

Clear and thin fluid, on the other hand, is not characteristic of lipohemarthrosis. Such clear fluid is more typically associated with other conditions, such as simple joint effusions without the presence of fat or significant blood, indicating a different underlying pathology. Therefore, the characteristic indicative of lipohemarthrosis would not include clear and thin fluid, as this suggests a lack of both blood and fat.
