Summary

The prevalence of knee osteoarthritis (OA) is rising worldwide, leading to disability and a reduced quality of life, particularly in elderly patients. While there are several treatment options, there is little consensus in the scientific community over which methods are most effective. Viscosupplementation with hyaluronic acid (HA) has been found to reduce pain in patients with knee OA over a period of up to 6 months, with little to no side effects. The aim of this prospective open-label, uncontrolled, observational, single-site study was to assess the efficacy and safety of a single hybrid HA injection over a period of 6 months in subpopulations of patients with low to severe symptomatic knee OA in everyday clinical practice. Fifty patients who met the inclusion criteria participated in the study. A single intra-articular ultrasound-guided injection of hybrid HA (Sinovial®) was administered. Patients submitted Visual Analog Scale (VAS) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaires at 28-, 42-, 84-, and 168-days post-treatment.

Interventions

Type	Name	Description
DRUG	Sinovial	A single intra-articular injection of hybrid HA complex, Sinovial® HL (IBSA Pharmaceuticals, Italy, patent number WO/2012/032151 ) in the knee was performed from the lateral approach to the suprapatellar recess using ultrasound. For the ultrasound-guided infiltration method, a sterile linear probe with a 20 G guide was used to visualize the joint suprapatellar recess and avoid intrasynovial infiltration. The patient was positioned supine with the knee in full extension. From the lateral approach to the suprapatellar recess, HA was then injected into the knee joint, verifying intra-articular positioning in real-time via ultrasound imaging (direct visualization of viscous fluid or air bubbles). Patients did not receive anti-inflammatory or pain-relieving drugs in the week before the first injection . Patients were evaluated at four time points: at baseline and after 28, 42, 84, and 168 days after the intervention. At each evaluation, clinical data relating to the status of the disea
