Baker’s Cyst

What is it?

Baker’s cyst refers to a persistent swelling which develops in the back of the knee.

How does it happen?

A Baker’s cyst most commonly develops following an injury to a structure within the knee joint. When this injury is left untreated it can result in ongoing swelling. The swelling can develop into a Baker’s cyst behind the knee.

How does it feel?

A Baker’s cyst results in obvious swelling on the back of the knee. The swelling may fluctuate from day-to-day depending on your activities. The swollen area may be tender when touched.

What should you do?

A Baker’s cyst generally does not get better on its own if its cause is not addressed. If you have or suspect you have a Baker’s cyst, you should consult your nearest sports physiotherapist to determine its cause and to have it treated.

What shouldn’t you do?

If you have or suspect you have a Baker’s cyst you shouldn’t ignore the problem. This may lead to your problem getting worse resulting in a prolonged recovery. In addition, you shouldn’t participate in activities which cause the cyst to increase in size.

Could there be any long-term effects?

A Baker’s cyst generally does not produce any long-term effects, as long as its cause is properly diagnosed and appropriately treated. If the cause is not treated, the Baker’s cyst will persist.

Management

The assistance of a sports physiotherapist is important in the treatment of Baker’s cyst. Primarily they will be able to determine why it has developed. This may require the use of imaging techniques such as X-ray, ultrasound or MRI. Treatment of the Baker’s cyst involves treatment of the underlying injury. This may involve activity modification, soft tissue treatment such as massage and stretching, and the progression through a series of specific strengthening exercises.
