Baker’s Cyst

Baker’s cyst symptoms can vary depending on the size of the cyst and underlying knee conditions. Many patients experience:

• Visible swelling or bulge behind the knee
• Feeling of tightness or fullness in the back of the knee
• Pain that worsens with knee movement or prolonged standing
• Stiffness and reduced range of motion in the knee
• Discomfort that radiates down the back of the calf
• Symptoms that worsen after physical activity

In some cases, a Baker’s cyst may rupture, causing sudden sharp pain and swelling that extends down into the calf, which requires immediate medical attention.

Baker’s cysts typically develop when excess synovial fluid accumulates due to underlying knee problems. Common causes include:

Underlying Conditions: Osteoarthritis, rheumatoid arthritis, meniscus tears, cartilage damage, and other knee injuries often lead to increased fluid production in the joint.

Risk Factors: Adults over 40 are more commonly affected, particularly those with arthritis or previous knee injuries. Athletes who participate in sports involving frequent knee stress may also be at higher risk. The cyst forms when pressure from excess fluid forces synovial fluid into the tissue behind the knee, creating the characteristic swelling.

At Synergy Health Partners, our orthopedic specialists use a comprehensive approach to diagnose Baker’s cysts. Your evaluation typically includes:

Physical Examination: Our doctors will examine your knee for swelling, tenderness, and range of motion limitations. We’ll also check for signs of underlying knee conditions that may be contributing to the cyst formation.

Advanced Imaging: MRI scans provide detailed images of the cyst and surrounding knee structures, helping us identify any underlying damage to cartilage, meniscus, or other joint components. Ultrasound may also be used to confirm the diagnosis and guide treatment decisions.

You should seek medical attention if you experience persistent knee swelling or pain that interferes with your daily activities. Schedule an appointment with our orthopedic team if you notice:

A visible bulge behind your knee that doesn’t resolve on its own, increasing pain or stiffness in the knee joint, difficulty walking or participating in normal activities, or signs of cyst rupture such as sudden, severe pain with swelling extending down your calf.

Early evaluation and treatment can prevent complications and address underlying knee problems that contribute to Baker’s cyst formation. Our specialists at Synergy Health Partners are experienced in managing both simple and complex cases.
