[Differences of clinical trails on domestic and international treatment of knee osteoarthritis with acupuncture].

Literatures on knee osteoarthritis treated by acupuncture both in China and abroad published in the mainstay periodicals in recent 10 years were selected, and analyses were done in the following aspects: (1) Randomization, (2) Control group, (3) Sample size, (4) Intervention measurements, (5) Intervention periods, (6) Evaluation on therapeutic effects, (7) Follow-up assessment, (8) Adverse effects, (9) Ratio of the lost case. The result indicates that differences can still be found on the trial designation in China and abroad. The domestic research design should be more comprehensively and strictly.
