Comparison of the Pain and Functional Improvement of Combined Extracorporeal Shockwave Therapy With or Without Intra-articular Hyaluronic Acid and Platelet-rich Plasma Injection on Advanced Osteoarthritis of the Knees.

Resumen breve

This was a single group, double-blind, randomized clinical trial that enrolled 48 patients with Kellgren-Lawrence grade II to IV osteoarthritis of the knee. Patients were randomly assigned to three groups: Saline + ESWT (S+E group), High Platelet-Rich Plasma (PRP + ESWT (P+E group), and Hyaluronic Acid + ESWT (HA + ESWT (H+E group). All patients were followed for one year. Assessments included the Visual Analogue Scale (VAS), serum enzyme-linked immunosorbent assay (ELISA), knee X-ray and ultrasound examinations, and functional scores (WOMAC, KOOS, and IKDC).
