The Efficacy and Safety of a Single-Dose Hyaluronic Acid Injection in the Treatment of Knee Osteoarthritis

HA therapy typically consists of several intra-articular injections administered at weekly intervals. A single-dose IA-HA treatment offers patients and physicians a treatment option that involves both lower costs and fewer clinic visits. Furthermore, considering the administration procedure, we believe that single-dose therapy helps reduce the risk of potential side effects. In light of this information, our study aims to retrospectively evaluate the efficacy and safety of HA in patients with symptomatic knee OA who have received a single-dose intra-articular HA injection.
