How to Treat a Baker’s Cyst Behind the Knee


A Baker’s cyst, also known as a popliteal cyst, is a fluid-filled swelling that develops behind the knee. It is typically caused by an underlying knee joint condition, such as arthritis or a meniscal tear. This article will discuss the symptoms, causes, treatment options, prevention, and when to seek medical attention for a Baker’s cyst.

What is a Baker’s Cyst?

A Baker’s cyst is a cystic mass that forms at the back of the knee joint. It is filled with synovial fluid, which is the lubricating fluid that surrounds the knee joint. The cyst usually develops as a result of increased production of synovial fluid or a blockage in the normal flow of the fluid.

Symptoms and Causes

The most common symptom of a Baker’s cyst is a visible swelling behind the knee. The swelling may be accompanied by pain, stiffness, and limited range of motion. The cyst is typically caused by an underlying knee joint condition, such as osteoarthritis, rheumatoid arthritis, or a meniscal tear. These conditions can lead to increased production of synovial fluid, which can accumulate and form a cyst.

Treatment Options

1. Rest and Ice

One of the initial treatment options for a Baker’s cyst is rest and ice. Resting the affected knee and applying ice packs can help reduce swelling and relieve pain. It is important to avoid activities that worsen the symptoms and to give the knee time to heal.

2. Medications

Over-the-counter pain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), can help reduce pain and inflammation associated with a Baker’s cyst. However, it is important to consult a healthcare professional before taking any medication, especially if you have any underlying medical conditions or are taking other medications.

3. Physical Therapy

Physical therapy can be beneficial in managing a Baker’s cyst. A physical therapist can provide exercises and stretches to improve knee strength, flexibility, and range of motion. They may also suggest modalities such as ultrasound or electrical stimulation to help reduce pain and swelling.

4. Corticosteroid Injections

Corticosteroid injections may be recommended for individuals with persistent pain and swelling from a Baker’s cyst. These injections help reduce inflammation and provide temporary relief. However, repeated corticosteroid injections should be avoided as they can weaken the surrounding tissues.

5. Aspiration

In some cases, a healthcare professional may recommend aspiration of the Baker’s cyst. During this procedure, a needle is used to drain the fluid from the cyst. This can provide immediate relief of symptoms, but the cyst may reoccur if the underlying knee joint condition is not addressed.

Prevention and Management

1. Strengthening Exercises

Engaging in regular strengthening exercises can help prevent the development of a Baker’s cyst. Strong muscles around the knee joint provide stability and support, reducing the risk of fluid accumulation and cyst formation. Consult a physical therapist or exercise specialist for a personalized exercise program.

2. Avoiding Overuse

Avoiding overuse of the knee joint can help prevent the development or worsening of a Baker’s cyst. This includes avoiding repetitive activities that put excessive stress on the knee, such as running or jumping. If you participate in high-impact activities, make sure to incorporate rest days and cross-training exercises to reduce the strain on the knee joint.

3. Proper Posture and Body Mechanics

Maintaining proper posture and body mechanics while standing, walking, and performing daily activities can help reduce the risk of developing a Baker’s cyst. Avoid excessive bending or twisting of the knee, and make sure to use proper lifting techniques to avoid straining the knee joint.

4. Maintaining a Healthy Weight

Excess weight puts additional stress on the knee joint, increasing the risk of developing a Baker’s cyst. Maintaining a healthy weight through a balanced diet and regular exercise can help reduce the strain on the knee and lower the risk of cyst formation.

5. Wearing Supportive Footwear

Proper footwear with adequate arch support and cushioning can help distribute the weight evenly and reduce the strain on the knee joint. Avoid wearing high heels or shoes that do not provide proper support, as they can increase the risk of knee injuries and cyst formation.

When to See a Doctor

It is important to consult a healthcare professional if you experience persistent pain, swelling, or limited range of motion in the knee. A doctor can evaluate your symptoms, perform a physical examination, and order additional tests, such as imaging studies, to confirm the diagnosis and develop an appropriate treatment plan.


In conclusion, a Baker’s cyst behind the knee is a fluid-filled swelling that can be caused by underlying knee joint conditions. Treatment options include rest and ice, medications, physical therapy, corticosteroid injections, and aspiration. Prevention and management strategies involve strengthening exercises, avoiding overuse, maintaining proper posture and body mechanics, maintaining a healthy weight, and wearing supportive footwear. If symptoms persist, it is important to seek medical attention to determine the underlying cause and receive appropriate treatment.
