Symptoms of a Baker’s cyst may include:
The cyst can rupture, leaking fluid down the inner leg and will sometimes cause the appearance of a painless bruise under the inner ankle. A baker's cyst rupture can mimic phlebitis - a swelling or inflammation of a vein that impairs the flow of blood - of the leg.
A Baker’s cyst is a fluid-filled swelling that causes a lump at the back of the knee. This condition is due to a problem that affects the knee joint, such as arthritis, inflammation from repetitive stress, or a cartilage injury. A Baker’s cyst often doesn’t need treatment and will go away on its own.
The presence of a knee effusion, which is excessive fluid inside the knee , will create fluid pressure that allows unidirectional passage of the fluid from the knee joint, through the valve, and into the cyst (Figure 2). A Baker's cyst is easier to see with the knee fully extended, especially when the patient is in the prone position.
M71. 22 - Synovial cyst of popliteal space [Baker], left knee. ICD-10-CM.
A Baker's cyst can form when joint-lubricating fluid fills a cushioning pouch (bursa) at the back of your knee. A Baker's cyst is a fluid-filled cyst that causes a bulge and a feeling of tightness behind your knee. The pain can get worse when you fully flex or extend your knee or when you're active.
Also called Baker cysts, these occur more frequently in boys, are usually found on the medial side of the popliteal fossa, and are painless. In children, the cysts are rarely associated with intra-articular pathology.
M71. 21 - Synovial cyst of popliteal space [Baker], right knee. ICD-10-CM.
The condition is named after the 19th century surgeon who first described it, Dr. William Morrant Baker. Baker's cysts typically result from a problem inside the knee joint, such as osteoarthritis or a meniscus tear. These conditions cause the joint to produce excess fluid, which can lead to the formation of a cyst.
Ganglion cysts are filled with gelatinous and viscous fluid in the neighbourhood of joints or tendon sheaths. They are frequently seen at joints and tendons of the wrist but are rare in the region of knee joint. The most common cysts in the knee region are popliteal also called Baker's cysts.
The knee contains sacs of fluid, called bursa, that help to cushion the joint and reduce friction between the structures around it. A Baker's cyst is a swelling on the back of the knee, caused by a build-up of excess fluid inside the bursa.
A Baker's cyst is a swelling behind the knee caused by an outpouching of the capsule. Like a meniscal cyst, a Baker's cyst can form from a meniscal tear. However, they also form from any knee condition that increases knee joint fluid, such as arthritis or ligament damage.
They are more common in adults. Significant trauma, juvenile idiopathic arthritis, infections (especially Lyme disease), and malignancy have all been associated with secondary cyst formation.

TreatmentMedication. Your doctor may inject a corticosteroid medication, such as cortisone, into your knee to reduce inflammation. ... Fluid drainage. Your doctor may drain the fluid from the knee joint using a needle. ... Physical therapy. Icing, a compression wrap and crutches may help reduce pain and swelling.
The knee joint is filled with a special fluid (synovial fluid) that cushions the joint. A Baker cyst forms when an injury or disease causes extra synovial fluid to leak into the extra space behind the knee. Baker cysts are common in both adults and children. But they're more common as a person gets older.

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as M71.2. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
