Abstract

Objective: To evaluate the efficacy and the tolerability of viscosupplementation (VS) with hyaluronic acid (Hylan GF 20) in a cohort of 36 patients affected by hip osteoarthritis through a 18 months follow-up. Methods: Viscosupplementation was performed with an anteriorsagittal approach, under ultrasound guidance. 36 patients were administered hyaluronic acid intraarticularly in the hip, with a unique injection of Hylan G-F20, which could be repeated after at least 3 months. Treatment efficacy was assessed by functional index WOMAC, pain evaluation on a visual analogue scale and NSAID consumption. All such parameters were recorded at the time of the first injection and then 3, 6, 9, 12 and 18 months later. Results: Statistically significant reduction of all parameters was observed three months after the injection, and was still maintained at the timepoints 6, 9, 12 and 18 months. No local side effects have been observed, nor systemic complications. Conclusions: Our data show that viscosupplementation is a promising approach for hip osteoarthritis, providing beneficial effects in a long-tern follow up. Yet, the topic deserves further and wider studies, so to define the number of injections to administer and suggest a fit interval between subsequent injections.
