Abstract:
Objective:To document the effectiveness of ultrasound-guided genicular nerve block (GNB) in treating knee osteoarthritis (KOA).Methods:A total of 92 KOA patients were randomly divided into an observation group and a control group with 46 in each. Those in both groups were treated conventionally, including with non-steroidal anti-inflammatory drugs, acupuncture, ultrasound, laser irradiation and manipulation therapy. The observation group additionally underwent ultrasound-guided genicular nerve block treatment, once a week for 2 weeks. Pain scoring on a visual analog scale (VAS), the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and a 6-minute walk test (6MWT) were used to evaluate everyone before and after the treatment, and then 8 weeks later.Results:In the observation group the average VAS rating [(3.54±2.00) at week 2 and (4.13±2.04) at week 8] and the average WOMAC subscale and total scores [(36.91±16.91) at week 8] had improved significantly right after the experiment and 8 weeks later. But in the control group this was true only right after the treatment. The observation group also demonstrated superior improvements in 6MWT distance at week 2 [(434.22±125.19)m] and week 8 [(446.35±126.45)m] compared to both its own baseline and the control group.Conclusions:Ultrasound-guided genicular nerve block is a rapid, precise, effective, and long-lasting intervention for alleviating pain, improving knee function and enhancing walking endurance in KOA patients.
