The present randomized controlled study investigated whether sonographic needle guidance affected the outcomes of intra-articular injection for osteoarthritis knee.Ninety-four noneffusive knees with were to by conventional palpation-guided anatomic landmark or image-guided enhanced a 1-handed mechanical (the reciprocating procedure device) syringe. After placement and synovial space dilation confirmed sonography, syringe exchange was performed, 80 mg triamcinolone acetonide injected second through indwelling needle. Baseline pain, procedural pain at outcome (2 weeks 6 months), responders, therapeutic duration, reinjection rates, total cost, cost per responder determined.Relative methods, knee resulted in 48% reduction (P < 0.001), 42% scores 0.03), 107% increase rate 52% nonresponder 36% duration = 0.01), 13% ($17) patient year, 58% ($224) year hospital outpatient 0.001).Sonographic reduced improved clinical cost-effectiveness injections osteoarthritic knee.
