Brief summary
The purpose of this study is to verify the efficacy and safety of acupuncture treatments (Individualized, Standardized acupuncture) for patients with knee osteoarthritis (OA).
Detailed description
The investigators targeted the patients with knee OA. After treatment in 4 groups - individualized acupuncture treatment, standardized acupuncture treatment, sham-needle treatment, and waiting groups - the investigators will compare the effects of pain relieving and daily performing improvement. So the investigators will confirm the efficacy of acupuncture, and further the best treatment method. In addition, the investigators are going to evaluate the safety of abnormal reaction during the treatment.
Interventions
PROCEDUREStandardized Acupuncture
The treatment was applied twice a week for 20 minutes for 6 weeks(12sessions) 9 Acupuncture points(SP9,GB34, ST36, ST35, Xiyan(EX-LE5), BL60, GB39, SP6 and KI3)were used for all the patients assigned to this group. Sterile Stainless Steel(25mm x 40mm) disposable acupuncture needles manufactured by Dong-Bang Acupuncture Co.(Korea) were used.
PROCEDUREsham acupuncture
The treatment was applied twice a week for 6 weeks(12sessions). The sham acupuncture was applied on the 9 same acupuncture points as in the standardized acupuncture group. Each session was 20 minutes long
PROCEDUREIndividualized Acupuncture
The treatment was applied twice a week for 20 minutes for 6 weeks(12sessions)
OTHERWaiting
No interventions were applied to the patients in this group.

| WOMAC (Western Ontario and McMaster Universities) Scale change | at 2nd(Baseline),8(after 3weeks of treatment),13th(after 6 weeks of treatment) and 14(follow up evaluation after 6 weeks from the last treatment) visit | WOMAC scale is checked by the patients. WOMAC scale is a tool to check of the disability, stiffness and pain by knee pain. |

| Patient global assessment(PGA) | at 2(Baseline), 3, 4, 5, 6, 7, 8(after 3weeks of treatment), 9, 10, 11, 12, 13(after 6 weeks of treatment), and 14th(follow up evaluation after 6 weeks from the last treatment) visit | 5 Grading of Investigator(1=Very good, 2=good, 3=fair, 4=poor, 5=very poor) |
| Adverse Events | at 2(Baseline), 3, 4, 5, 6, 7, 8(after 3weeks of treatment), 9, 10, 11, 12, 13th(end of treatment) visit | Any unpredicted symptoms were checked at each follow up visit and if any, the symptom, time of occurrence, and length of duration were recorded and reported. |
| Investigator global assessment(IGA) | at 2(Baseline), 3, 4, 5, 6, 7, 8(after 3weeks of treatment), 9, 10, 11, 12, 13(after 6 weeks of treatment), and 14th(follow up evaluation after 6 weeks from the last treatment) visit | 5 Grading of Investigator(1=Very good, 2=good, 3=fair, 4=poor, 5=very poor) |
