Doctor explains Bakers Cyst (Popliteal Cyst) | Causes, symptoms & treatment

In this video, I delve into the topic of Baker's Cyst, a condition that can cause discomfort and concern for many. A Baker's Cyst, also known as a popliteal cyst, is a fluid-filled swelling that forms behind the knee. It can manifest as a noticeable bulge, leading to feelings of tightness or pain, especially when straightening the leg or engaging in physical activity. Understanding this condition is crucial not only for your health but also for the well-being of your family and friends who may experience similar issues.

So, what exactly is a Baker's Cyst? It occurs when synovial fluid, the lubricating fluid within the knee joint, accumulates and forms a small sac behind the knee. This can happen due to various reasons, primarily when the knee joint becomes swollen or inflamed, leading to an overproduction of fluid. Common causes include knee injuries, such as cartilage tears, or underlying joint conditions like osteoarthritis, rheumatoid arthritis, or gout. While Baker's Cysts are more prevalent in individuals aged 30 to 70, they can also occur in younger adults and children.

Now, let’s discuss the symptoms you should be aware of. Some individuals may not experience any symptoms aside from a soft swelling at the back of the knee. However, others may feel tightness or pressure, pain that radiates down the calf, or even a clicking sensation when moving the knee. In more severe cases, the cyst can rupture, leading to sudden sharp pain, swelling, and redness in the lower leg. It’s essential to recognize these symptoms, as a ruptured Baker's Cyst can mimic more serious conditions like deep vein thrombosis (DVT), which requires immediate medical attention.

If you notice a lump behind your knee that doesn’t go away, or if you experience pain, swelling, or clicking in the joint, it’s time to consult your healthcare provider. They will perform a physical examination and may recommend imaging tests, such as an ultrasound or MRI, to confirm the diagnosis and rule out other potential issues.

When it comes to treatment, not all Baker's Cysts require intervention. If you’re asymptomatic and the cyst isn’t affecting your mobility, your doctor may suggest a watchful waiting approach. However, if you’re experiencing discomfort, there are several treatment options available. For mild symptoms, self-care measures can be quite effective. Over-the-counter pain relief, such as paracetamol or ibuprofen, can help manage pain. Applying an ice pack to the affected area can reduce swelling, and resting the knee while avoiding overuse is crucial. A knee support can also provide additional stability. I highly recommend checking out our video featuring Ella Boy, a qualified physiotherapist, where she shares five exercises to help manage knee pain associated with a Baker's Cyst. You can find that video linked in the description box below.

If home treatments don’t alleviate your symptoms, your doctor may consider medical interventions. Corticosteroid injections can help reduce inflammation, while aspiration—draining the fluid with a needle—may be an option for larger cysts. However, this may be less effective for long-standing cysts with thick fluid. If the cyst is a result of an underlying joint condition like arthritis, managing that condition is vital, as reducing inflammation in the joint can lead to improvement in the cyst itself.

In cases where the cyst ruptures, treatment typically involves rest, elevation of the leg, and pain management. The leaked fluid is usually reabsorbed by the body over a few weeks. If there’s any uncertainty regarding the diagnosis, particularly if symptoms suggest a possible blood clot, your doctor may order an ultrasound to rule out DVT.

In rare instances, surgery may be necessary, especially if there’s significant damage within the knee or if the cyst persists despite medical management. The most common surgical procedure is arthroscopy, a minimally invasive technique where a camera is inserted into the knee to repair cartilage or remove inflamed tissue. It’s important to note that simply removing the cyst is rarely done, as it often recurs if the underlying issue isn’t addressed.
