Hypertonic Dextrose Injection for The Treatment of a Baker's Cyst

Abstract

We present extremely rare and interesting case of a Baker's cyst treated with hypertonic dextrose injection. A 54-year-old female patient had a Baker's cyst which was diagnosed by an ultrasonography. After the failure of the two-weekly conservative treatment, we injected hypertonic dextrose (25%) into her right knee joint for the treatment of a Baker’s cyst. Two weeks after the injection, the patient reported improvement in posterior knee pain, and an US showed a resolution of the posterior knee cyst. Certainly hypertonic dextrose injection for the treatment of a Baker’s cyst appears to be a reasonable treatment option. Further studies are needed in order to elucidate the efficacy of hypertonic dextrose injection in the treatment of Baker’s cysts.
