- Abstract
Background: Selective genicular artery embolization (GAE) has shown promise as a minimally invasive treatment option for persistent symptomatic recurrent effusions (REs) following total knee arthroplasty (TKA). Purpose: We sought to investigate the radiographic and clinical success of GAE for RE after TKA. Methods: We performed a retrospective review of prospectively collected data on primary and revision TKA patients with RE, both hemorrhagic and non-hemorrhagic, who underwent GAE between 2019 and 2021 with a minimum of 6-month follow-up. All embolization procedures were performed by a single interventional radiologist. Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and visual analog scale (VAS) scores were collected prior to GAE and at 1, 3, and 6 months post-procedure. Recurrence of effusion following GAE was assessed at 6 months using ultrasound. Results: Seventeen patients, 10 female and 7 male, with 18 TKAs and a mean (SD) age of 63.1 (8.6) years were included. We saw a mean (SD) of 36.1 (24.4) and 3.3 (3.0) point improvement in WOMAC and VAS scores, respectively. In addition, 14 of the 18 TKAs (77.8%) seen at final follow-up had complete resolution of effusion confirmed by ultrasound. Conclusion: Our retrospective review found that a majority of patients showed significant clinical improvement and resolution of effusion following GAE. These findings suggest that GAE may be an effective minimally invasive treatment option for RE following TKA and should be further investigated. [ABSTRACT FROM AUTHOR]
