| Osteoarthritis, Knee Pain | Device: Hydrogel injection | Not Applicable |
Prospective, multicenter study, unmasked, single-arm, to study the safety and efficacy of a new hydroxyethyl cellulose hydrogel for the treatment of the knee pain caused by osteoarthritis. The working hypothesis is that the effect of hydrogel use on the study population will result in a reduction in pain in the knees affected by symptomatic OA.
The general objective of this study is to generate clinical evidence of the safety and efficacy of the new hydrogel used as a treatment of symptomatic knee osteoarthritis.
The patient's perception of the pain caused by osteoarthritis in the knee joint before and after the treatment under evaluation will be quantify. Subjects' quality of life before and after treatment will also be evaluated. Monitoring of the adverse events associated with the use of the device under evaluation will be determined. Subjects will be follow-up for 12 months.

- Pain assessment: Percentage of pain reduction using a visual analogue scale [ Time Frame: Change from Baseline at postoperative 12 months follow-up ]Percentage of pain reduction using a visual analogue scale (Wong-Baker scale) where Face 0: does not hurt at all and Face 10: hurts as much as you can imagine
- Improvement of Quality of life: KOOS [ Time Frame: Baseline, and postoperative at 1, 3, 6 and 12 months follow-up ]
Quality of life (QoL-Status) - defined as improvement of the QoL of the subjects, compared to the baseline values for KOOS (Knee injury and Osteoarthritis Outcome Score) questionnaire.
The KOOS questionnaire was developed as an instrument to assess the patient's opinion about their knee and associated problems.The KOOS questionnaire measures 5 subscales: pain referred by the patient, other specific symptoms of the disease, function in daily life activities, function in sport and recreation and quality of life related to the knee. All items have 5 possible response options (from 0 to 4) where 0 indicates no problems and 4 indicates extreme problems, and each of those 5 scores is calculated as the sum of the included items. The scores are transformed on a scale of 0 to 100, which 0 represents extreme knee problems and 100 indicates no symptoms. The score ranges from 0 to 100, separately for each sub-scale. A change of 10 points or more is considered a clinically significant change.
- Improvement of Health status [ Time Frame: Change from Baseline at postoperative at 1, 3, 6 and 12 months follow-up ]Health Status assessed with 12-Item Short-Form Health Survey (SF-12). It consists of 12 items (grouped in 8 health concepts: physical function, physical role, bodily pain, general health, vitality, social function, emotional role and mental health) from which two summaries are constructed: physical and mental. The higher the score on the scales indicates the better health.
- Patient Global Impression [ Time Frame: Change from Baseline, up to three days after injection, postoperative at 1, 3, 6 and 12 months follow-up ]Patient Global Impression with the his/her osteoarthritis will be evaluated with a visual analogue scale (Wong-Baker scale) where Face 0: represents an inactive osteoarthritis, that is, without symptoms and Face 10: represents a very active osteoarthritis, that is, with severe symptoms.
- Rate of Adverse Events [ Time Frame: At injection, at three days after injection, postoperative at 1, 3, 6 and 12 months follow-up ]All adverse events will be registered.
