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.
