What are Bakers Cysts?

Today we delve into a common yet often misunderstood condition affecting the knee joint, Baker’s cysts. Baker’s cysts in the knee are also known as popliteal cysts. They are fluid-filled sacs that develop at the back of the knee. These cysts are usually the result of underlying conditions causing increased production of synovial fluid. This is the fluid that lubricates the knee joint. When excess synovial fluid accumulates, it can bulge into the back of the knee, forming a cyst.

This fluid build-up is usually caused by joint conditions like osteoarthritis and rheumatoid arthritis, injuries/trauma to the knee like with meniscus or ligament injuries, or with other conditions such as gout or infections. These conditions cause an increase in fluid pressure within the knee. This leads to a “bubble” forming or cyst, similar to blowing up a small balloon. The bottom line is anything that causes increased synovial fluid production or increased inflammation in the knee can lead to a Baker’s cyst.
