**Ultrasound breakthrough offers hope to stop arthritis before it starts**
This ultrasound treatment may help stop arthritis before it starts 

### Introduction
A non‑invasive ultrasound technique has shown early promise in halting the molecular cascade that leads to osteoarthritis, according to a multicenter trial published this week. Researchers say the approach targets inflammatory signaling within cartilage before structural damage becomes visible on imaging, offering a potential shift from symptom management to true disease prevention.

### Key Developments
The study, led by teams at Johns Hopkins University and the University of Toronto, applied low‑intensity pulsed ultrasound (LIPUS) to the knee joints of 124 participants with early‑stage radiographic changes but no clinical pain. Treatments were administered three times weekly for eight weeks. Biomarker analysis revealed a 38 % reduction in serum cartilage oligomeric matrix protein (COMP) and a 22 % drop in interleukin‑1β levels compared with sham
