What is a joint effusion?

It is important to exclude septic arthritis because of rapid joint destruction in bacterial infection.\n\nMost effusions are due to bruising within the joint from acute trauma or from unaccustomed overuse of the joint. The wcause may not be immediately apparent owing to the delay in symptoms developing. Cartilage bruising subsides slowly and so warn the patient of the risk of wear if the cartilage is not treated gently while softened by oedema.\n\nEffusions serve to separate, nourish and lubricate bruised cartilage and so NSAID's and tight compression should probably be used with caution to avoid long term harm. The RICE physiotherapy plan remains the best treatment.\n\nSometimes there is more serious joint derangement requiring surgical, usually arthroscopic, intervention, such as for a bucket-handle tear of a meniscus in the knee.

abnormal fluid collection in the knee joint.  Usually from some sort of problem such as: arthritis, infection, torn cartilage, brusies, injuries, too thin blood causing bleeding into the joint, and extremely rarely tumors.  You should make sure you see a doctor.

Joints\n\nA joint, or articulation, is the place where two bones come together. There are three types of joints classified by the amount of movement they allow: immovable, slightly movable, and freely movable.\n\nImmovable joints are synarthroses. In this type of joint, the bones are in very close contact and are separated only by a thin layer of fibrous connective tissue. An example of a synarthrosis is the suture in the skull between skull bones.\n\nSlightly movable joints are called amphiarthroses. This type of joint is characterized by bones that are connected by hyaline cartilage (fibro cartilage). The ribs that connect to the sternum are an example of an amphiarthrosis joint.\n\nMost of the joints in the adult human body are freely movable joints. This type of joint is called a diarthrosis joint. There are six types of diarthroses joints. These are:\n\nBall-and-Socket: The ball-shaped end of one bone fits into a cup shaped socket on the other bone allowing the widest range of motion including rotation. Examples include the shoulder and hip.\n\nCondyloid: Oval shaped condyle fits into elliptical cavity of another allowing angular motion but not rotation. This occurs between the metacarpals (bones in the palm of the hand) and phalanges (fingers) and between the metatarsals (foot bones excluding heel) and phalanges (toes).\n\nSaddle: This type of joint occurs when the touching surfaces of two bones have both concave and convex regions with the shapes of the two bones complementing one other and allowing a wide range of movement. The only saddle joint in the body is in the thumb.\n\nPivot: Rounded or conical surfaces of one bone fit into a ring of one or tendon allowing rotation. An example is the joint between the axis and atlas in the neck.\n\nHinge: A convex projection on one bone fits into a concave depression in another permitting only flexion and extension as in the elbow and knee joints.\n\nGliding: Flat or slightly flat surfaces move against each other allowing sliding or twisting without any circular movement. This happens in the carpals in the wrist and the tarsals in the ankle. \n\nP.S.  does this help you?

I've heard it called a bursa before.  My doctor described it as a collection of fluid - sometimes they will use a cortisone shot to reduce it.  I had one in my knee, but they couldn't use cortisone bc it's back for the tendon.  Good luck!

when you get a pancreatitis (inflammation of the pancreas), the pancreatic secretion may enter the pleural space through retroperitoneal space. so if amylase raises in pleural fluid, it may indicates that effusion is of pancreatic origin. \nglucose helps differentiate the nature of pleural fluid.\nfor example, glucose > 40 mg/dl: no infection\nglucose < 40mg/dl: infection probable.

CO2 is carried through the blood in the body to the lungs to be exhalated.

Sometimes fluid accumulates between the thin, transparent membrane (pleura) covering your lungs and the membrane that lines the inner surface of your chest wall — a condition known as pleural effusion\n\nNormally, the pleurae are silky smooth, allowing your lungs to slide easily along your chest wall when you breathe in and out. But when the pleurae around your lungs become inflamed (pleurisy) — often as a result of pneumonia — fluid can accumulate and may become infected (empyema). In that case, you may have a tube placed between your ribs to drain the fluid or, occasionally, a surgical procedure to clear out some of the infected material.

diffusion, which is the tendency of molecules to move from a higher area of concentration (more molecules) to an area of lesser concentration (less molecules). when an equilibrium is reached (both areas have same concentration) diffusion ends.\ndiffusion of water is called osmosis\nions are diffused using facilitated diffusion, which use protein channels http://en.wikipedia.org/wiki/Facilitated_diffusion\ncarbon dioxide is also transported by diffusion

Synovial joints (or Diarthroses, or diarthroidal joints) are the most common and most moveable type of joint in the body.\n\nWHICH MEANS IT IS A SYNOVIAL JOINT THERE ARE NO "TYPES"

A pulmonary embolism is a blood clot that has traveled into the pulmonary (lung) circulation and lodged there, blocking blood flow.  This prevents blood from picking up oxygen at the lungs, so the body tissues can starve from hypoxia.  A saddle pulmonary embolus is probably the worst case scenario.  Whereas most pulmonary emboli are very small (and probably not even clinically significant), saddle emboli lodge where the pulmonary artery divides to the left and right lung.  Blood flow is blocked to both lungs, and death is imminent.\n\nBig emboli like that often form in the large leg veins, especially if someone has been very inactive for an extended period (e.g. a long hospital stay).  Clotted blood isn't the only material that can cause an embolus.  Anything that gets in the bloodstream can cause a blockage -- air, fat, amniotic fluid, bacterial vegetations, and on and on.

Arthritis, because every time you crack a joint, you're bursting out the liquid between the joints that keep the bones from rubbing against each other.

arthritis? or lack of liquid and cushion left between the joint?

The knee is a complex, compound, condyloid variety of a synovial joint. It actually comprises two separate joints. The femoro-patellar joint consists of the patella, or "kneecap", a so-called "sesamoid bone" which sits within the tendon of the anterior thigh muscles, and the patellar groove on the front of the femur through which it slides. The femoro-tibial joint links the femur, or thigh bone, with the tibia, the main bone of the (lower) leg. The joint is bathed in a viscous fluid which is contained inside the "synovial" membrane, or "joint capsule". The recess behind the knee is called the "popliteal fossa".

The effusion is drained based on symptoms.  Pain or shortness of breath are the prime indicators.  Otherwise it is not necessary to routinely drain the effusion if he is asymptomatic.
