What causes a Baker’s Cyst?
MRI - An MRI (magnetic resonance imaging) exam would help your doctor check for any issues arising from complications with a suspected Baker's Cyst, such as a quickly growing cyst or symptoms of fever.
What appears to be a Baker’s cyst may in fact be something more serious, such as a:
Stiffness of your knee. Limited range of motion and ability to bend your knee. Swelling of your knee and/or leg. Sometimes, a Baker’s cyst can cause swelling and redness in your lower leg that can be similar to the symptoms of a blood clot. A blood clot is an emergency situation. If you are ever in doubt, reach out to your healthcare provider ...
ICD-10 code M71. 21 for Synovial cyst of popliteal space [Baker], right knee is a medical classification as listed by WHO under the range - Soft tissue disorders .
ICD-10 code L72. 3 for Sebaceous cyst is a medical classification as listed by WHO under the range - Diseases of the skin and subcutaneous tissue .
M71. 22 - Synovial cyst of popliteal space [Baker], left knee | ICD-10-CM.
Baker's cyst infection may result in a surgical emergency in which the surgeon should be aware not only of the knee involvement but also about the possible dissemination to the calf. We suggest always suspecting the presence of a cyst, particularly in cases of recurrent septic knee arthritis.
L72. 3 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM L72. 3 became effective on October 1, 2021.

In some cases, a Baker's cyst causes no pain, and you may not notice it. If you do have signs and symptoms, they might include: Swelling behind your knee, and sometimes in your leg.
The synovial fluid is typically sterile, and rupture does not commonly result in infection. Treatment is conservative. In contrast, infected ruptured Baker's cyst may present with painful limb swelling, fever, and persistent leukocytosis.
But in very rare cases, a Baker's cyst can rupture and can have a presentation similar to that of deep vein thrombosis (DVT) or acute thrombophlebitis [2,3]. The ruptured Baker's cyst can also present with infection and, rarely, compartment syndrome [4].
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.
Sometimes, a Baker's cyst can cause swelling and redness in your lower leg that can be similar to the symptoms of a blood clot. A blood clot is an emergency situation. If you are ever in doubt, reach out to your healthcare provider right away.
Baker's cysts aren't dangerous and they may go away on their own. But occasionally they burst, and if that happens, synovial fluid can leak into the calf below, causing pain, swelling, and reddening.
The recommended treatment for a ruptured cyst is rest and elevation (keeping the affected calf raised). Prescription painkillers – usually a combination of paracetamol and codeine – can also be used to control any pain.
Popliteal vein thrombosis happens when a blood clot blocks one of the blood vessels behind your knees. It's a serious condition, but it can sometimes be mistaken for a less-dangerous condition called a Baker's cyst.
