At Wimbledon Clinic Physio, we frequently encounter patients with joint-related conditions that can cause discomfort, swelling, and reduced mobility. Two common conditions we treat are ganglion cysts and Baker’s cysts. While both involve fluid accumulation near or within a joint, their origin, symptoms, and treatment approaches differ. Below, we explore these conditions and how innovative therapies like thermal ultrasound can aid recovery.
What Are Ganglion Cysts?
A ganglion cyst is a benign, fluid-filled sac that forms near joints or tendons, most commonly in the wrists and knee area. These cysts are filled with thick, jelly-like synovial fluid, often resulting from localised trauma or repetitive stress on the joint. We see these increasingly due to our relationship with Vista Health and their 3T MRI SCANNING TECH and more ultrasound technology being used. They are often mentioned as incidental findings from surgeons and GPs and are usually not even mentioned to our clients.
Why was I not told about my knee cyst? The NHS sees these as harmless as they cause dysfunction but not disease, and surgeons often don't have the severity of the symptoms to treat them, which is a risk-to-benefit situation. Many surgeons will refer you to physiotherapy, but if the cyst has been there for a chronic length of Time and has started to harden, typical physiotherapy won't work. We suggest you get a copy of your reports. The clinic will review if you think you have a ganglion cyst.
Although generally harmless, ganglion cysts can:
- Cause discomfort or pain if they press on nerves or tendons.
- Restrict movement, mainly when located near weight-bearing joints like the knee.
What Are Baker’s Cysts?
A Baker’s cyst, or popliteal cyst, is a synovial cyst that forms in the back of the knee. It is directly connected to the joint capsule and filled with synovial fluid, typically as a result of:
- Knee joint inflammation, such as arthritis.
- Meniscal injuries or other internal knee trauma.
Symptoms of a Baker’s cyst include swelling, stiffness, and a feeling of tightness in the back of the knee, which can worsen with movement or bending. Unlike ganglion cysts, Baker’s cysts often reflect underlying joint issues rather than being isolated occurrences.
Key Differences Between Ganglion and Baker’s Cysts
Feature Ganglion Cyst Baker’s Cyst
Origin Outside the joint capsule Directly connected to the joint capsule
Location Near tendons or joints (e.g., wrist, knee) Back of the knee (popliteal region)
Contents Thick, jelly-like synovial fluid Normal synovial fluid
Associated Conditions Localized trauma or repetitive stress Arthritis, meniscal tears, synovitis
Symptoms: Visible lump, localised pain or nerve compression, Swelling, knee stiffness, tightness
Thermal Ultrasound Therapy for Cyst Treatment
While ganglion and Baker’s cysts differ in origin, ultrasound therapy offers a non-invasive option to alleviate discomfort and enhance healing. At Wimbledon Clinic Physio, we use advanced thermal ultrasound as part of our treatment protocol for these conditions.
How Does Thermal Ultrasound Work?
Thermal ultrasound delivers deep heat to tissues using high-frequency sound waves, promoting:
- Increased circulation: Enhancing blood flow to the area, reducing inflammation, and encouraging the natural reabsorption of fluid.
- Cleaning cyst walls: Making aspiration (fluid removal) more effective.
- Pain relief: Relaxing surrounding tissues and reducing nerve irritation.
Benefits of Ultrasound Therapy
- Non-invasive: It avoids surgical intervention in mild to moderate cases.
- Improves mobility: Reduces stiffness around the affected joint.
- Quick sessions: Treatment typically lasts 5–10 minutes without downtime.
Limitations
While thermal ultrasound can reduce symptoms and promote healing, it is most effective when combined with other treatments, such as aspiration, strengthening exercises, or addressing underlying joint conditions.
Comprehensive Treatment at Wimbledon Clinic Physio
At Wimbledon Clinic Physio, our approach goes beyond symptom management. For both ganglion and Baker’s cysts, we focus on:
- Diagnosis: Advanced imaging, including ultrasound, is used to identify the root cause of the cyst.
- Personalised care plans: Tailored rehabilitation exercises to strengthen surrounding muscles and reduce joint stress.
- Innovative therapies, Including ultrasound therapy, joint aspiration, and, in severe cases, guided referral for surgical consultation.
- Prevention strategies: Addressing underlying joint issues, like arthritis or meniscal injuries, to minimise recurrence.
When Should You Seek Help?
If you experience persistent pain, swelling, or restricted movement due to a ganglion or Baker’s cyst, it’s essential to seek professional care. While many cysts resolve independently, larger or symptomatic cysts may require intervention to prevent long-term joint damage.
At Wimbledon Clinic Physio, located within the Wimbledon Clinic, we combine advanced technology with expert care to treat various musculoskeletal conditions. Whether you’re dealing with a ganglion cyst, a Baker’s cyst, or general knee discomfort, our team is here to help you achieve long-lasting relief and better joint health.
