What is a Baker’s Cyst?

The knee is the largest joint in the body, and one of the most easily injured. It is made up of four main structures: bones, cartilage, ligaments, and tendons. Three bones meet to form your knee joint: your thigh bone (femur), shinbone (tibia), and kneecap (patella). A Baker’s cyst or popliteal cyst is a small benign (non-cancerous) cyst on the back of the knee. A Baker’s cyst forms when knee joint-lubricating synovial fluid builds up in the back of the knee.

Common Causes:

• Osteoarthritis
• Knee inflammation
• Knee injuries

Some patients may have a Baker’s cyst and not know because it is asymptomatic. Symptomatic Baker’s cysts may cause the following:

• Pain
• Swelling
• Stiffness and decreased range of motion

When you arrive for your initial consultation, Orthopedic Physicians Alaska (OPA) knee specialist will evaluate your areas of concern, discuss your symptoms, and develop a customized and comprehensive treatment plan tailored to your unique needs. This evaluation is a necessary part of diagnosing your condition and providing the best possible care.

When diagnosing a Patellar Instability, the OPA specialist will provide:

• A medical, injury, and symptom history review
• A physical examination
• Multiple view x-rays or MRI

Once an official diagnosis is made, a customized treatment plan is prescribed. Treatment plans decrease symptoms as quickly as possible.

Common Treatments:

Many Baker’s cysts will disappear on their own. Others may require treatment. Nonsurgical treatment options treat Baker’s cysts:

NSAIDs

Decrease inflammation and pain.

Immobilization

A brace and crutches take the weight off the knee.

Physical Therapy

OPA approved physical therapist will provide exercises to strengthen the collateral ligament and surrounding muscles, ligaments and tendons.
