A Baker’s Cyst, or popliteal cyst, is a fluid-filled swelling that forms in the back of the knee joint, typically between the tendons of the hamstring and the calf. This occurs when there is an overproduction of synovial fluid (the lubricating fluid in the joint), which builds up and creates pressure, forming a bulge behind the knee.

While the cyst itself is not always dangerous, it is often a sign of an underlying joint problem—most commonly arthritis, meniscal tears, or other chronic inflammatory conditions. Left untreated, it can lead to joint stiffness, restricted mobility, and even rupture of the cyst, causing pain and swelling in the calf area.

What Causes a Baker’s Cyst?

Baker’s Cyst isn’t a condition on its own—it’s usually the result of a deeper knee joint issue. The following problems may cause inflammation and excess fluid, leading to cyst formation:

• Knee Osteoarthritis – age-related wear and tear of the knee joint.
• Rheumatoid Arthritis – chronic autoimmune inflammation that increases synovial fluid.
• Meniscus Tear – particularly the medial meniscus, which irritates the joint lining.
• Knee Ligament Injuries – such as ACL or MCL sprains that cause inflammation.
• Overuse and Repetitive Movements – common in athletes or runners.
• Knee Trauma or Post-Surgical Inflammation – increases joint fluid production.

These underlying conditions increase joint pressure, pushing excess fluid into the back of the knee, where it collects in a pocket and forms a cyst.

Symptoms of a Baker’s Cyst

Symptoms may vary based on the size and pressure of the cyst. Common signs include:

• A visible swelling or lump behind the knee
• Tightness or stiffness when bending or extending the knee
• Pain or pressure in the back of the knee that worsens with activity
• Reduced range of motion
• A clicking or locking sensation in the joint (if associated with a meniscus tear)
• Swelling in the lower leg if the cyst ruptures and fluid travels downward

Some smaller cysts may go unnoticed and are only discovered through imaging.

How is a Baker’s Cyst Diagnosed?

At RegenOrthoSport, we begin with a thorough physical exam, followed by diagnostic imaging to confirm the presence of a Baker’s cyst and to identify the underlying cause. Diagnostic tools include:

• Ultrasound – quick and effective for identifying fluid-filled cysts.
• MRI – provides detailed images of joint structures, meniscus, and surrounding tissue.
• X-rays – useful in detecting arthritis or bone changes contributing to cyst formation.

Understanding the source of inflammation or joint damage is key to planning effective treatment—not just draining the cyst.

Why Regenerative Medicine Works Better Than Conventional Treatment

Traditional treatments like pain relievers, ice therapy, physical therapy, corticosteroid injections, or aspiration (draining the fluid) may provide temporary relief, but they rarely prevent recurrence. The key to long-term resolution lies in treating the root cause.

This is where non-surgical regenerative treatments such as Platelet-Rich Plasma (PRP) and Bone Marrow Aspirate Concentrate (BMAC) offer a powerful advantage. These non-surgical treatments repair underlying tissue damage, reduce inflammation at the joint level, and help normalize fluid production—eliminating the reason the cyst formed in the first place.

Regenerative Treatment Options at RegenOrthoSport

We offer several cutting-edge, non-surgical orthopedic treatment options for patients suffering from recurrent or painful Baker’s cysts:

Platelet-Rich Plasma (PRP) Therapy

PRP involves drawing a small amount of the patient’s blood, processing it to concentrate the platelets, and injecting the PRP into the affected knee. The growth factors in PRP stimulate tissue repair, reduce inflammation, and help heal meniscal or cartilage injuries that contribute to cyst formation.

Bone Marrow Aspirate Concentrate (BMAC)

BMAC is rich in mesenchymal stem cells and healing cytokines. When injected into the inflamed joint under ultrasound guidance, it promotes deep healing of arthritis and soft tissue damage—addressing the primary driver of excessive joint fluid.

Image-Guided Precision

All injections are performed using real-time ultrasound or fluoroscopic guidance to ensure that the biologics are placed exactly where healing is needed. This maximizes the effectiveness of each treatment.

Frequently Asked Questions (FAQs)

Will a Baker’s cyst go away on its own?
Sometimes small cysts resolve naturally, but larger or symptomatic ones usually require treatment of the underlying joint condition.

What happens if the cyst ruptures?
You may feel sharp pain, swelling, and redness in the calf. It’s important to get evaluated to rule out other complications like DVT.

Can PRP or stem cell therapy remove the cyst?
These therapies don’t “remove” the cyst directly, but by healing the internal joint, they stop the fluid buildup that causes the cyst.

Is cyst aspiration effective?
Draining the fluid can offer quick relief, but the cyst often returns unless the underlying cause is treated.

How long does recovery take after regenerative therapy?
Most patients resume light activities within a few days, with pain and swelling improving over 2–6 weeks.

Is the procedure done under anesthesia?
No general anesthesia is needed. The procedures are minimally invasive and performed in-clinic.

Is this treatment safe for older adults with arthritis?
Yes. Regenerative therapies are safe, natural, and well-tolerated across age groups.
