MR-Guided Focused Ultrasound for the Management of Osteoarthritic Knee Pain
A Japanese study published in BMC Musculoskeletal Disorders and reported in Medscape showed that local bone denervation by MR-guided focused ultrasound has been demonstrated as a promising tool for pain relief of bone metastases. Eight patients with medial knee pain and eligible for total knee replacement were included. MR-guided focused sonication treatments were applied the target sites. The pain intensity during walking was assessed on a 100 mm visual analog scale (VAS) before and after treatment.
Six patients showed immediate pain alleviation after treatment, and four of them demonstrated long-lasting effect at 6-month follow up. There were no adverse side effects or complications during and after treatment.
Comment: This therapy is promising and innovative. It’s a pretty small sample size though.
