Fibrin glue as a non-invasive outpatient treatment for post-arthroscopic knee seromas

Post-surgical seromas and cysts have been reported across many surgical subspecialties including orthopaedics. Treatments include both invasive surgical approaches and more recently reported non-invasive techniques. Non-invasive approaches currently include compressive wrapping, vasopneumatic cryotherapy, and motion exercises. Persistent lesions have been treated with talc or doxycycline sclerodesis. This case presents a patient with a post-arthroscopic seroma that was treated with fibrin glue in an outpatient setting. Fibrin glue has not been reported in the post-arthroscopy outpatient setting to address cystic lesions. This case suggests a viable non-invasive treatment option for these lesions.
