Inclusion criteria
* Eighteen (18) years old or above; * Patient signed informed consent form; * Patients with stable symptoms related to knee osteoarthritis for at least 3 months prior to screening; * Failure, inadequate response or intolerance to analgesics and/or NSAIDs or low-grade opioids; * Kellgren-Lawrence radiographic stage: II-III diagnosed in the previous 12 months; * WOMAC average pain index score \> 40 mm and \< 90 (on a VAS 0-100 mm) on the knee to be treated; * Difference ≥ 10 mm between the WOMAC average pain score of the knee to be treated and WOMAC average pain score of the contralateral knee at screening; * Body Mass Index (BMI) inferior to 35 kg/m2 (weight/height).
Exclusion criteria
* Concomitant inflammatory joint disorder; * Had received previous visco-supplementation treatment in the study knee within 6 months or intra articular corticosteroids within 3 months\* prior to inclusion; * Infection in or around the study knee; * Relevant skin disease in the area of injection site; * Documented presence of injury or trauma of the study knee at screening, including evidence of a subchondral fracture, meniscal lesion, presence of bone or cartilage fragments in the study knee; * History of allergy or intolerance to sodium hyaluronate; * Documented presence of osteonecrosis in one or both knees; * Inability to understand the study procedure; * Participation in another clinical trial within 30 days prior to screening; * Ongoing therapy with daily dosage \> 101 mg of acetylsalicylic acid as part of cardiovascular preventive treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety and tolerability | 6 months | Primary objective of this study is to assess the safety and tolerability of EVI-01 following single intraarticular administration in the knee joint, assessed with adverse events monitoring throughout the follow up duration of six months. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in patient-reported pain intensity | 7 days | Change in patient-reported pain intensity at Days 1 to 7 compared to baseline will be assess using a 0-100 mm Visual Analogue Scale (VAS), in which 0 means ''no pain at all'' and 100 means ''the worst possible pain''. |
| Change in WOMAC index | 6 months | The Western Ontario and McMaster Universities Arthritis Index (WOMAC) consists of a total of 24 questions divided in 5 questions related to pain, 2 questions related to stiffness and 17 questions related to difficulties in performing activities of daily living in relation to physical function. Each question refers to a 0-100 mm Visual Analogue Scale (VAS) in which 0 means ''no pain at all'' and 100 means ''the worst possible pain''. Change in WOMAC pain, stiffness, function and total score will be assess using WOMAC index at Day 7, Day 14, Day 30, Day 90 and Day 180 compared to baseline |
| Patient satisfaction for the overall treatment effect | 6 months | Measurements of relief satisfaction by the patient will be assess using a 7 points Likert scale at Day 180. A 7 point Likert scale offers 7 different answer options related to an agreement that would be distinct enough for the respondents (Very good, Good, Fairly good, Same as before, Fairly bad, Bad, Very bad). |
| Physician satisfaction for the overall treatment effect | 6 months | Measurements of relief satisfaction by the physician will be assess using a 7 points Likert scale at Day 180. A 7 point Likert scale offers 7 different answer options related to an agreement that would be distinct enough for the respondents (Very good, Good, Fairly good, Same as before, Fairly bad, Bad, Very bad). |
