[Intra-articular treatment with Hylan G-F 20 under ultrasound guidance in hip osteoarthritis. Clinical results after 12 months follow-up].
Hip is a site very commonly affected by osteoarthritis (OA), yet few data exist in literature regarding intra-articular use of hyaluronic acid in this pathology. We evaluated the efficacy of Hylan G-F 20 hip viscosupplementation performed under ultrasound guidance. We enrolled 26 patients affected by symptomatic hip OA and treated them with a single intraarticular injection of Hylan G-F 20, which could be repeated every two months. The injection was performed under ultrasound guidance with an antero-superior approach. Treatment efficacy was assessed through Lequesne index, visual analogue scale (VAS) pain quantification, and NSAID intake at the timepoint zero (baseline), and after 2, 6 and 12 months. We observed a statistically significant reduction of all considered parameters at the timepoints 2 and 6 months, when compared to baseline. At 12 months the changes were still statistically significant for all parameters for about 50% of the patients. No side effect was observed, nor systemic complication. Viscosupplementation is a promising approach for hip OA, although further and wider studies are wanted to determine how long the beneficial effect lasts, and what is the optimal number of injections to administer.
