Study Overview
Brief Summary
A Phase III, prospective, multicentre, non-controlled, with consecutive participant enrollment in order to evaluate the efficacy, safety and duration of the effects of the viscosupplementation with a preparation of sodium hyaluronate 2% (SH2%) from Tedec-Meiji Farma S.A. over 12 months. Adult patients diagnosed with primary osteoarthritis of the knee according to American College of Rheumatology (ACR) criteria with radiological grades II and III according to Kellgren-Lawrence scale (KL) will receive a single injection of SH2% and will be followed for 1 year with follow up visits at 6 and 12 months.
At 6 months patients could be offered a second injection whenever and when they comply with the criteria established for re-treatment and will be followed for additional 6 months
Detailed Description
Prospective, multicentre and non-controlled study. Each patient will receive a single injection of SH 2% and will be followed for 1 year with follow up visits at 6 and 12 months At 6 months follow up visit patients will be offered a second injection whenever and when they comply with the criteria established for re-treatment and will be followed for additional 6 months From the pre-inclusion V0 up to the V1 (beginning of treatment), there will be a wash-out period of 2 weeks during which only paracetamol will be allowed for osteoarthritis (OA) pain relief (maximum dose allowed:3g/day).
Paracetamol will be discontinued at least 24h before follow up visits (Treatment administration, 6 months of follow up and 12 months of follow up).
Clinical evaluation will be done every visits through VAS, WOMAC and Patient's Global Assessment/ Investigator's Global Assessment (PGA/IGA)

Arms & Interventions
Experimental: Sodium Hyaluronate 2%
Each patient will receive a single injection of SH2%
Intervention: Sodium hyaluronate 2% (Device)
Outcomes
Primary Outcomes
Change in pain intensity according to VAS (0-100mm)
Time Frame: 6 and 12 months after treatment
The VAS to be used in the study consists of a horizontal line marked from 0 to 100 mm, where 0 means no pain and 100 is the greatest possible pain. Patients must draw a vertical line at the point that they believe that represents the pain intensity at that time.
Secondary Outcomes
- Change in function from baseline in the target knee(6 and 12 months after treatment)
- Patient and investigator global assessments(6 and 12 months after treatment)
- Percentage of patients achieving the Patient Acceptable Symptoms State (PASS)(6 and 12 months after treatment)
- Percentage of patients achieving the Minimally Clinical Important Improvement (MCII)(6 and 12 months after treatment)
