Knee Pain Cut by 57% With New Artery Block Device
6 Jul
Summary
- Device reduced knee osteoarthritis pain by 57% in European study.
- 80% of patients met minimum clinically important difference.
- No moderate-to-severe adverse events were reported with the device.
A novel device designed to block arteries has demonstrated a significant 57% reduction in knee osteoarthritis pain among patients in a European clinical study. Researchers at Charité - Universitätsmedizin Berlin published findings in Radiology, detailing the treatment's impact on 194 individuals who had not responded to previous therapies.
The Nexsphere-F, a fast-resorbable microsphere treatment, also led to statistically significant improvements in knee osteoarthritis outcome measures. Approximately 80% of patients treated with Nexsphere-F surpassed the minimum clinically important difference threshold, indicating substantial clinical benefit.
This device showed a remarkable safety record, with no moderate-to-severe adverse events linked to the treatment. NextBiomedical, the South Korea-based developer, currently holds a CE mark for the device in Europe and is pursuing a US market presence through the ongoing RESORB clinical trial.
Osteoarthritis, affecting about 7.6% of the global population, presents a growing challenge. GAE, the procedure employing Nexsphere-F, aims to alleviate pain by obstructing abnormal blood vessels in the inflamed knee lining using resorbable microspheres.
Unlike permanent particle methods, Nexsphere-F's transient skin discolouration occurred in only 6.3% of procedures, resolving within 24 hours, contrasting with other approaches that may cause long-term discolouration.
