Abstract: [Objective] To explore the best dosage of extracorporeal shock wave therapy (ESWT) for moderate knee osteoarthritis by comparison of the short- term clinical outcomes with different energy flux density of ESWT. [Methods] A total of 150 knees with moderate osteoarthritis were included into this study, and divided equally into five groups, the A, B, C, D and E groups, which received ESWT for 4 weeks with the energy flux density of 0.06 mJ/mm2, 0.10 mJ/mm2, 0.14 mJ/mm2, 0.18 mJ/mm2 and 0.22 mJ/mm2 respectively. The visual analogue scale (VAS) for knee pain, Lysholm score and WOMAC osteoarthritis index score were used to evaluate the clinical conditions before treatment, 1 month and 12 months after treatment. [Results] In term of comparison among time points, the VAS and WOMAC score were at the highest before treatment, significantly declined to the lowest at 1 month after treatment, and then rose again to the middle at 12 months, conversely, the Lysholm scores were at the lowest before treatment, significantly increased to the highest at 1 month after treatment, and decreased again to the middle at 12 months after treatment in all the 5 groups, which were of statistical significance (P<0.05) . Although no statistically significant differences were noticed regarding the VAS, Lysholm and WOMAC scores among the 5 groups before treatment (P>0.05) , the VAS and WOMAC scores ranked down-up as D group C group >B group >E group >A group, with statistical differences among the 5 groups at 1 month and 12 months after treatment (P<0.05) . [Conclusion]
