Baker's Cyst: Treating the Cause, Not Just the Cyst
A Baker’s cyst (popliteal cyst) is a fluid-filled sac that forms at the back of the knee, causing a visible bulge, tightness, or aching in the popliteal fossa. Contrary to common belief, the cyst itself is rarely the primary problem. It is a symptom of an underlying intra-articular condition such as knee OA or a meniscus tear that is generating excess synovial fluid.
At Palm Beach Regenerative, the approach to Baker’s cyst is to identify and treat the underlying knee pathology driving the fluid production, which typically causes the cyst to resolve on its own. Reach out today to Request a Consultation at our practice.
What Is Baker's Cyst?
The knee joint communicates with the popliteal bursa at the back of the knee in many adults. When excess synovial fluid accumulates in the knee from arthritis, meniscus tears, or other joint pathology, it can push into this bursa, creating the Baker’s cyst. Treating the cyst alone without addressing the underlying cause leads to recurrence.
Signs and Symptoms
- A palpable bulge or swelling behind the knee
- Tightness or fullness at the back of the knee, particularly with knee bending
- Aching in the popliteal area
- In some cases, calf pain or swelling if the cyst ruptures (must be distinguished from deep vein thrombosis)
Common Causes and Risk Factors
- Knee osteoarthritis (most common cause in older adults)
- Meniscus tears generating excess joint fluid
- Inflammatory arthritis (rheumatoid, gout)
- Any intra-articular condition producing synovial effusion
How It Is Diagnosed
Ultrasound clearly identifies the Baker’s cyst, its size, and whether it has ruptured. MRI is the most valuable imaging tool for identifying the underlying intra-articular pathology driving the cyst.
Dr. Ghattas focuses the evaluation on identifying the underlying knee diagnosis rather than simply characterizing the cyst.
Conventional Treatment Options
- Aspiration of the cyst: Provides temporary relief but high recurrence without treating the source
- Steroid injection into the knee joint
- Treating the underlying condition (arthritis, meniscus tear) surgically or conservatively
The Palm Beach Regenerative Approach
Dr. Ghattas treats the underlying intra-articular knee condition driving the Baker’s cyst with image-guided orthobiologic injection into the knee joint. When the synovitis and joint inflammation is addressed at its source, the excess fluid production decreases and the cyst typically resolves without direct aspiration.
This root-cause approach to Baker’s cyst is what distinguishes the Palm Beach Regenerative philosophy. Give us a call today to learn more.
The BioMod Advantage: MLS Robotic Laser Therapy to the knee reduces the intra-articular synovitis driving Baker’s cyst formation. Xymogen anti-inflammatory and joint support protocols reduce the systemic inflammatory burden contributing to knee synovial fluid overproduction.
Like all medical procedures, interventional orthobiologics have potential risks and benefits. Results vary by individual. Not all patients are candidates. Dr. Ghattas will discuss your specific situation, realistic expectations, and all treatment options, including when surgery or other interventions may be more appropriate.

Patient Experiences
"I had severe knee pain and was looking for proper knee pain treatment, which is how I found Dr. Ghattas on Instagram. I was a bit hesitant at first, but it turned out to be one of the best decisions I’ve made for my health. Francia was amazing at coordinating all my consultations and making the whole process easy and stress-free.

"Over a year ago, both my daughter and I underwent PRP treatment with Dr. Ghattas—PRP for my left knee and PRP for my daughter’s L4-L5 and sacral region. We wanted to wait long enough to truly evaluate the results before sharing our experience. I am pleased to say that the outcomes have been outstanding. My daughter’s improvement has been remarkable, and the treatment has made a significant difference in her quality of life. I have also experienced excellent results with my knee. Dr. Ghattas is an exceptional physician who combines expertise, professionalism, and genuine care for his patients. We are incredibly grateful for the treatment we received and the positive impact it has had on our lives. Thank you, Dr. Ghattas. We are truly grateful for everything you have done. You are simply the best."

“Apart from the exemplary personal service by the reception and the staff that makes us feel we're at home at the clinic, I have experienced remarkable healing in several episodes from shoulder issue to knee injuries and hip pain. The doctor is so thorough in the diagnosis phase that he administered exactly what was needed, no more no less! Thank you folks for a wonderful experience.”
RG G
“I am quite active and go to pilates 3-4 times per week. I was having left knee pain and which was treated with PRP. It took about 3 months for me to feel better but then the pain completely subsided. I now am able to exercise without the fear that I will tear a ligament and am pain free.”

"The Regenexx process has been nothing short of amazing. The pre-treatment MRI (performed at an independent facility) indicated that my knee was far worse than the physical symptoms I was experiencing. The treatment process was exactly as Dr. Ghattas explained...."
