Introduction
Baker’s cyst is a fluid-filled swelling that forms behind the knee. It is also called a popliteal cyst. Many women experience knee pain and swelling, and sometimes, a Baker’s cyst is the cause. This condition can affect daily life, especially for women who are active or pregnant. Understanding Baker’s cyst helps you know what to expect and when to seek help.
What is a Baker’s Cyst?
A Baker’s cyst is a lump filled with fluid that appears at the back of your knee. It forms when extra fluid from the knee joint collects in a small sac. This sac can swell and cause discomfort. Although it is not usually dangerous, it can be bothersome. In women, changes in hormones or joint stress during pregnancy may increase the risk.
Symptoms of Baker’s Cyst
Many people with a Baker’s cyst notice a bulge behind their knee. However, some may not have any symptoms. Common signs include:Swelling or a lump behind the kneeKnee pain, especially when bending or straightening the legStiffness or tightness in the kneeSometimes, swelling in the lower legFeeling of pressure or fullness behind the knee
Sometimes, the cyst can burst. If this happens, you may feel sharp pain, redness, or swelling in your calf. If you notice these signs, seek medical help right away.
Causes and Risk Factors
Baker’s cyst often develops when the knee joint makes too much fluid. This can happen for several reasons. For example, arthritis, knee injuries, or overuse can lead to extra fluid. In women, pregnancy and hormonal changes may also play a role. Other risk factors include:Osteoarthritis or rheumatoid arthritisSports injuries to the kneeRepeated stress on the knee jointObesity, which puts extra pressure on the knees
According to the CDC, joint problems are more common in women, especially as they age.
Diagnosis of Baker’s Cyst
