Sclerotherapy of Baker's cyst with imaging confirmation of resolution.

BACKGROUND Baker's cysts are commonly encountered in pain management practices. OBJECTIVE To ascertain if sclerotherapy treatment of a Baker's cyst could produce objectively verifiable MRI imaging changes. DESIGN Case report. METHODS A 52-year-old white male with a posterior horn of the medial meniscus tear and a large Baker's cyst who had failed conservative care and drainage was imaged before treatment with sclerosing. Three injections of 12.5% dextrose and anesthetic with sodium morrhuate were injected intraarticular into the right knee after drainage. RESULTS The Baker's cyst resolved on both postoperative imaging after the completion of care as well as on physical examination. CONCLUSIONS Prolotherapy in this case study seemed to be an effective treatment for Baker's cyst in this patient.
