Baker's Cyst

A Baker's cyst, also known as a popliteal cyst, is a fluid-filled swelling that develops at the back of the knee. It often feels like a tight, water-filled balloon and can cause a visible bulge. This happens when your knee joint produces too much lubricating fluid, known as synovial fluid. When the joint is irritated or injured, this extra fluid is pushed into a small sac behind the knee, leading to pressure and discomfort.

You might notice that its harder to fully straighten your leg or bend your knee completely. The area may feel tight or achy, especially after you have been active or standing for a long period. While the cyst itself is the visible symptom, it is usually a sign that something else is happening inside the knee joint that needs professional attention.

• Swelling behind the knee
• Stiffness and tightness
• Pain that worsens with activity
• Difficulty fully bending the knee

• Osteoarthritis resulting in joint wear and tear
• Meniscus tears causing fluid overproduction
• Rheumatoid arthritis or other inflammatory conditions
• Direct trauma or sports injuries to the knee
• Chronic knee joint swelling (effusion)
• Gout causing irritation within the joint

• Adults aged 35 to 70 due to degenerative changes
• Athletes with a history of meniscus or ligament tears
• Individuals with existing joint conditions like arthritis
• People with past knee surgeries who have lingering stiffness
• Those with physically demanding jobs requiring frequent kneeling
• Patients with chronic inflammatory disorders

At Physical Therapy Now, we focus on treating the underlying cause of the Baker's cyst to reduce the swelling and prevent it from returning. You will work 1-on-1 with a licensed physical therapist who will first assess your knee's range of motion and joint stability. We use manual therapy techniques, including gentle joint mobilizations and soft tissue massage, to improve fluid drainage and restore normal movement to the knee joint. We also utilize modalities like cryotherapy and electrical stimulation to manage pain and decrease the pressure behind your knee.

Your treatment plan will include specific exercises designed to strengthen the muscles surrounding the knee, such as the quadriceps and hamstrings. Strengthening these areas takes the pressure off the joint itself, which helps regulate fluid production. We also focus on flexibility, using guided stretching to ensure the back of the leg doesn't become too tight. As you progress, we will incorporate functional movements like squats or balance work to ensure your knee can handle daily activities without irritation.

Our goal is to get you back to your normal routine without the constant feeling of tightness or pain. Physical therapy is a highly effective, conservative first step in managing these cysts and avoiding more invasive measures. If your pain persists, is not improving in 2-3 weeks, or is getting worse, call us or schedule an appointment today at Physical Therapy Now.

Recovery usually occurs in phases over 4 to 8 weeks. The first phase focuses on reducing inflammation and regaining initial mobility. In the middle phase, you will build strength to support the joint. The final phase involves a return to full activity levels. While the cyst may physically shrink quickly, the underlying joint health must be addressed to ensure long-term relief and prevent the fluid from accumulating again.

• Apply ice packs to the back of the knee for 15 minutes several times a day
• Keep your leg elevated above your heart when resting
• Wear a compression sleeve to provide support and control swelling
• Avoid high-impact activities like running or jumping temporarily
• Perform gentle ankle pumps to encourage circulation
• Use a stool to avoid deep squatting or kneeling
• Limit your standing time if you notice the tightness increasing
• Wear supportive footwear to maintain proper leg alignment

These tips support recovery but don't replace a professional evaluation. If you're unsure or symptoms worsen, please reach out.
