OBJECTIVE: Several studies on knee osteoarthritis suggest that the intra-articular administration of hyaluronic acid products may be a relevant option in the management of patients with persistent pain. The aim of this study is to report the data of efficacy of US-guided HyalOne®/Hyalubrix® 60 injections in a large population of patients with hip osteoarthritis, repeated at least 2 times per year for up to seven years.
PATIENTS AND METHODS: This is a prospective, post-marketing, cohort study. Data were collected from the ANTIAGE registry. Values of Lequesne index, pain VAS, NSAIDs intake, global medical and patients assessments were evaluated every six months from the baseline to the end of the follow-up, seven years later. The inclusion criteria were: age ≥18 years, symptomatic hip osteoarthritis of at least 1-year duration, and up to 84 months of follow-up. All the patients received hyaluronic acid injections at least every six months, using ultrasound guidance to ensure accurate placement.
RESULTS: 1022 patients were included in the study. The patients were categorized by age classes, gender, and body mass index (BMI). All the groups show a statistically significant reduction at all time points compared to baseline values of Lequesne index, pain VAS, NSAIDs intake, global medical and patients assessments. There are slight differences in the subgroups of overweighted, obese and over 70 years patients.
CONCLUSIONS: Our study supports the clinical efficacy and safety of HyalOne®/Hyalubrix®60 in patients affected by osteoarthritis. This is the first study, reporting on a large cohort of patients in different categories with a long follow-up on seven years. The data confirm the proper use of ultrasound-guided viscosupplementation (VS) as background therapy in the management of hip osteoarthritis.Free PDF Download
