Single arm clinical investigation, post-market confirmatory interventional to assess performance, safety and tolerability of "CR500 SINGLE-DOSE GEL" medical device in patients with knee osteoarthritis (KOA).
Subjects 26-83 years old will receive CR500 SINGLE-DOSE GEL given for the treatment of osteoarthritis of the knee over a 4-week time period. The primary objective of the study is to evaluate the effect of CR500 SINGLE-DOSE GEL in the treatment of KOA.

| CR 500™ SINGLE-DOSE GEL | Device | CR 500™ SINGLE-DOSE GEL is a hydrogel to be applied to intact skin, useful to attenuate the physiological degeneration of cartilage typical of osteoarthritic processes. The presence of sodium hyaluronate facilitates the movement of joints and tendons for greater mobility and flexibility |
| Measure | Description | Time Frame |
|---|---|---|
| OA evaluation, measured by Lequesne Knee Index (LKI) | The primary efficacy endpoint of the study will be the evaluation of the clinical performance of the CR 500™, used as intended in patients affected by KOA, in variation of symptoms related to the physiological degeneration of cartilage typical of osteoarthritic processes, in terms of difference in LKI score between the end study visit and baseline visit. Lequesne Knee Index Score: minimum index score: 0 maximum index score: 24 0 means none OA >= means extremely severe OA | 4 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Lequesne Knee Index (LKI) Score | To evaluate the clinical performance of the CR 500™ across the study by Lequesne Knee Index (LKI) score. Lequesne Knee Index Score: minimum index score: 0 maximum index score: 24 0 means none OA >= means extremely severe OA | 4 weeks |
| Lequesne Knee Index (LKI) Subscore |
