[Effect of acupuncture on knee injury and osteoarthritis outcome score in patients with knee osteoarthritis].

Researchers in China studied whether acupuncture could help people with knee osteoarthritis, a common condition that causes pain and stiffness in the knee joint. The study included 42 patients who were randomly assigned to receive either real acupuncture or sham (fake) acupuncture for comparison. The real acupuncture group received needles at traditional acupuncture points around the knee and on the lower leg, including points like Dubi (ST 35), Zusanli (ST 36), and Yinlingquan (SP 9). Treatment sessions lasted 30 minutes and were given three times per week for 8 weeks. Researchers measured improvements using the Knee injury and Osteoarthritis Outcome Score (KOOS), which tracks pain, symptoms, daily activities, sports function, and quality of life. Both groups showed some improvement, but the real acupuncture group experienced significantly better results in two important areas: pain reduction and ability to perform daily activities. These improvements were seen immediately after the 8-week treatment period and were still present at an 18-week follow-up visit. This suggests that acupuncture may provide lasting benefits for people struggling with knee osteoarthritis pain and mobility issues. While both groups improved to some degree, those receiving real acupuncture had better outcomes in the areas that matter most for daily functioning. If you're considering acupuncture for knee osteoarthritis, seek treatment from a licensed acupuncturist trained in traditional Chinese medicine.

This randomized controlled trial compared traditional acupuncture versus sham acupuncture in 42 patients with knee osteoarthritis (40 completed). The acupuncture group received needling at 5-6 local points (ST 35, EX-LE 4, EX-LE 2, SP 9, SP 10, ST 36) and 3-4 distal points (GB 31, GB 36, GB 39, GB 41) with 30-minute retention. Controls received shallow needling at non-acupoints. Treatment was administered three times weekly for 8 weeks. The primary outcome was KOOS scoring across five domains. Both groups showed significant within-group improvements (P<0.05) in all KOOS dimensions post-treatment and at 18-week follow-up. However, the acupuncture group demonstrated statistically superior improvements in pain scores and daily activities compared to sham treatment (P<0.05). The study suggests acupuncture provides specific therapeutic effects beyond placebo for pain reduction and functional improvement in KOA patients, with benefits sustained at 18 weeks post-treatment.
