Sclerotherapy of Baker's cyst with imaging confirmation of resolution

Abstract

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.
