Intra-Articular Adelmidrol 2%/Hyaluronic Acid 1% With or Without m/umPEA, in Knee Pain Due to Joint Degeneration.
25 juni 2026 bijgewerkt door: Universita di Verona
Efficacy of Intra-articular Treatment With Adelmidrol 2% / Hyaluronic Acid 1%, With or Without m/umPEA, in Knee Pain Due to Joint Degeneration: a Bicentric, Prospective, Randomized Study.
Degenerative knee joint diseases are characterized by chronic pain, inflammation, and functional impairment. In these conditions, mast cell density in the synovial membrane is increased, resulting in an excessive release of biological mediators involved in key mechanisms of neuroinflammation and in hyaluronic acid depolymerisation. Adelmidrol acts as a preventive antioxidant due to its radical scavenging activity, thus protecting hyaluronic acid from oxidative degradation and reducing mast cell degranulation. Furthermore, a reduction in endogenous Palmitoylethanolamide (PEA) levels also contributes to joint neuroinflammation and disease progression; therefore, its exogenous supplementation may represent a valuable supportive strategy.
The objective of this clinical investigation is to compare the efficacy of intra-articular adelmidrol/hyaluronic acid treatment alone versus the same intra-articular treatment combined with oral micronized /ultramicronized PEA in patients with knee joint degeneration due to osteoarthritis or rheumatoid arthritis.

Tijdsspanne |
|---|---|---|

Change in joint symptoms and function
Tijdsspanne: Baseline (T0) and 1 month after treatment (T3)
|
Evaluation of degenerative joint disease symptoms and function assessed by Western Ontario and McMaster Universities (WOMAC) scale, a self-report questionnaire consisting of 24 questions divided in pain (5 items), joint stiffness (2 items) and functional limitations (17 items). Each question has 5 possible answers, evaluated on a Likert scale, from 0 (none) to 4 (extreme):
The sum of the individual scores results in an overall score from 0 to 96 (96 indicates severe disability). |

Change in pain intensity
Tijdsspanne: Baseline (T0), 1 week (T1), 2 weeks (T2), 1 month after treatment (T3), 3 months after treatment (T4) and 6 months after treatment (T5)
|
Evaluation of pain intensity assessed by the Visual Analogue Scale (VAS) scored from 0 mm to 100 mm, where 0 indicates 'no pain' and 100 corresponds to 'the worst pain ever possible'.
The higher the score, the more severe the pain.
|
Baseline (T0), 1 week (T1), 2 weeks (T2), 1 month after treatment (T3), 3 months after treatment (T4) and 6 months after treatment (T5)

|
Change in patients' quality of life
Tijdsspanne: Baseline (T0), 1 month after treatment (T3), 3 months after treatment (T4) and 6 months after treatment (T5)
|
Quality of Life evaluated by the 12-Item Short Form Health Survey (SF-12).
The SF-12 is a self-reported health questionnaire.
The score produces two summary measures: a mental (MCS-12) and a physical component score (PCS-12).
The PCS-12 score is derived from the subdimensions of general health, physical functioning, role physical, and bodily pain, while the MCS-12 score is derived from the subdimensions of social functioning, role emotional, mental health, and energy.
Scores range from 0 to 100, with higher scores indicating better physical and mental health functioning.

Incidence of Treatment-Related Adverse Events (Safety and Tolerability)
Tijdsspanne: From first treatment administration up to 6 months after treatment
|
