ABSTRACT
PURPOSE:
To describe our technique of aspirating symptomatic anterior cruciate ligament (ACL) mucinous cysts in the posterior intercondylar notch with ultrasound guidance, and to detail short-term patient outcomes.METHODS:
We identified 13 patients from February 2008 to May 2020 who underwent ultrasound-guided aspiration of symptomatic ACL mucinous cysts in the posterior intercondylar notch. Post-procedural imaging was reviewed to evaluate the degree of cyst decompression. Needle size was noted. Post-procedural symptomatology was also assessed.RESULTS:
No or minimal fluid was initially aspirated in 11/13 (84.6%) patients. For the two patients in which the cysts were aspirated completely with initial needle placement, with no need for lavage, a 13-gauge trocar was utilized. Of the remaining cysts, 10/11 were aspirated with an 18-gauge needle and one with a 20-gauge needle. Subsequent lavage was performed in 10 of the remaining 11 patients. After lavage, in eight there was a reduction of at least 50% volume by retrospective image interpretation; of 25% to 50% volume in one patient and of less than 25% volume in one patient. Five of the 13 patients reported immediate post-procedural symptomatic relief. In the other patients, immediate efficacy or post-procedural symptomatology was not documented.CONCLUSION:
Aspiration of symptomatic ACL mucinous cysts is a safe procedure and can provide symptomatic relief that may be temporary, but useful clinically. We recommend needles larger than 18 gauge for the best chance of successful aspiration.Palavras-chave
