Combined Use of PRP and Hyaluronic Acid for Infiltrative Treatment of Patients With Knee Osteoarthritis

Summary

"PRP+HA-23" is a double-blind randomized controlled clinical trial with 1:1:1 allocation. The objective of the study is to evaluate by a randomized controlled, double-blind clinical trial the efficacy and safety of viscosupplementation-associated PRP infiltration compared with PRP-only or HA-only infiltration for the treatment of patients with knee osteoarthritis.

5. Failure, defined as the persistence of symptomatology, after at least one course of conservative treatment (pharmacological, physiotherapeutic or infiltrative treatment);
6. Hemoglobin \> 11 g/dl; Platelet count \> 150,000 plt/mm3 (Recently performed CBC examination);
7. Ability and consent of patients to actively participate in clinical follow-up;
8. Signature of informed consent.

Exclusion Criteria:

1. Patients unable to express consent;
