About

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.

Trial design

50 participants in 1 patient group

Fifty consecutive patients who met the inclusion criteria participated in the study

Description:

Consecutive patients with knee osteoarthritis and with a medical indication for viscosupplementation with hybrid hialuronic acid (HA) who fulfilled the inclusion criteria were recruited for the study. The inclusion criteria were: a medical indication for viscosupplementation therapy with hybrid HA; patients aged between 45 and 80 years; diagnosis of femorotibial gonarthrosis associated with femoro-patellar arthrosis or isolated, gonarthrosis symptoms for at least 6 months; patients who failed to respond to analgesics and/or regular NSAIDs, or were proved to be intolerant to the regular use of analgesics, NSAIDS, or weak opioids; grade 2 to 3 OA in the Kellgren-Lawrence grading scale ; pain when walking measured by the Visual Analog Scale of at least 40 mm on the targeted knee; and contralateral knee pain when walking with aVAS of less than 10 mm. The exclusion criteria were: inability to understand the aim of the study, inability to provide acceptable consent, pregnancy, serious ps
