A Baker's cyst can be diagnosed upon physical examination alone.
However, as few signs and symptoms of a Baker's cyst appear similar to those of more severe conditions such as a blood clot, aneurysm or tumor, your doctor may advise the following noninvasive imaging studies:
In most cases, no treatment is required as a Baker's cyst resolves on its own.
For conditions where the cyst is painful and large enough, your doctor may advise the following treatments:
Medication: Your doctor can directly inject a steroid medication such as cortisone, into your knee to reducethe joint inflammation. This relieves pain, but may not prevent the recurrence of the cyst.
Fluid drainage: Your doctor may drain out the fluid collected in the knee joint with the help of a needle. This technique is called needle aspiration, and is often undertaken with ultrasound guidance.
Physical therapy: Application of ice, a compression wrap, and use of crutches may help decrease the pain as well as swelling. Your physical therapist will teach some gentle range-of-motion and knee muscle strengthening exercises that help relieve your symptoms and preserve the functions of your knee.
Most often, doctors recommend treatment for the underlying cause of the cyst.
If your doctor has found out that a cartilage tear is the cause for the overproduction of synovial fluid, surgical removal or repair of the torn cartilage is recommended.
Surgical treatment is rarely needed for Baker's cysts associated with osteoarthritis, as it usually improves with conservative treatment methods.
6 Lifestyle and Coping
There are different ways to adapt your lifestyle in coping with Baker's cyst.
If arthritis has been causing the Baker's cyst, your doctor will advice you to follow certain measures such as:
Following the R.I.C.E. principles. The acronym ""RICE"" stands for rest, ice, compression and elevation.
Rest your leg: Restrict certain activities that may stress your knee.
Ice your knee: The application of ice over the affected area reduces pain and swelling
Compress your knee with the application of a wrap, sleeve or brace
Elevate your leg whenever possible, particularly while sleeping during the night.
Medications such as ibuprofen (Advil, Motrin IB), naproxen sodium (Aleve, others), acetaminophen (Tylenol, others), and aspirin may reduce pain.
Follow the dosage instructions printed on the package. Taking more than the recommend dosage may be harmful.
Doing so will decrease the irritation in your knee joint.
Your doctor will advise on the time period for which you need to limit your physical activity, and alternative forms of exercises will be suggested in the meantime.
