Does suprapatellar recess need to be aspirated before hyaluronic acid injection?
5 answers
Aspiration before hyaluronic acid (HA) injection is a debated safety measure. Studies suggest that pre-injection aspiration may not always guarantee safe injection status due to potential false-negative results, especially with non-fluid fillers like HA. Factors influencing aspiration time include the filler's elastic modulus, cohesivity, and needle lumen size, with insufficient evidence for other associations like HA concentration or needle length. Proper technique, such as slow-pull retraction and waiting time, is crucial to ensure effective removal of filler from the needle. In vivo tests with rabbits showed positive aspiration results when the needle was primed with saline, emphasizing the importance of technique in preventing vascular embolism. Therefore, while the suprapatellar recess may not always need aspiration before HA injection, following recommended aspiration techniques is essential for safe and effective injections.
