What Is a Baker’s Cyst?
A Baker’s cyst is a fluid-filled lump that forms behind the knee. Doctors also call it a popliteal cyst. Often, it happens when extra fluid builds up in the knee joint. This can cause swelling and discomfort. Many people notice Baker’s cyst symptoms like a bump or tightness behind the knee. Sometimes, the cyst is linked to knee problems such as arthritis or injury. According to the CDC, knee swelling is a common reason people visit their doctor.
