Other than Surgery, Aspiration is one of the most accepted treatments for Ganglion or Baker’s cysts. The Ganglion or Baker’s cysts may recur after the aspiration process is done as much as 67%. If the cyst recurs, aspiration can be repeated. Having multiple aspirations may eventually help with the recurrence of the ganglia cyst. For more Info. (National Library of Med.)
Even though the aspiration procedure is simple to preform it does not effectively remove the roots (nucleus) of the cyst, so the ganglion cyst may return (recur) after aspiration. In fact, the recurrence rate may be as high as 70 percent. If the cyst recurs, aspiration can be repeated. Having multiple aspirations may eventually result in no recurrence of the cyst.
Your doctor may recommend a steroid injection into the empty cyst after aspiration which is very painful. Combined with aspiration, steroid injections may reduce the recurrence rate of the cyst. However, the ganglion cyst may still recur and your doctor may recommend surgery to remove the cyst. (see surgery) The roots (nucleus) may be dissolved by the I.B.V.S system. (click Here)
