Limited Evidence to Support the Use of Intra-Articular Injection of Hyaluronic Acid for the Management of Hallux Rigidus: A Systematic Review.

This systematic review suggests that intra-articular injection of HA for the treatment of hallux rigidus may lead to improved clinical outcomes with a low complication rate at short-term follow-up. However, the low level and quality of evidence underscores the need for further high-quality studies to be conducted to identify the precise role of HA in the treatment of hallux rigidus.
