Patients having secondary osteoarthritis according to the Ochronosis, Hemochromatosis or systemic disease. Patients who have severe pain like Sudek's atrophy, Paget's disease, Spinal disc herniation. Poly-articular patients who have suffered seriously by osteoarthritis at other parts affect judge of the knee joint pain. Patients who diagnosed clear interval disappearance at the knee joint by X-ray.

Patients who have joint effusion trouble were judged as a positive by tests like Patella tap test. 15. Patients who have target knee joint gotten surgical operation history including Arthroscopy within past one year (In case of having other side of knee joint or hip joint gotten surgical operation history, excepting the patients if there is possibility which can influence the target knee joint's appraisal. 16.

The contraception by medically permitted method: Condom, In case of using injection or insertion, In case of installing a intrauterine contraception device etc. 21. Pregnant and lactating women 22. Patients who were injected other investigational product over a time within 30 days before participated in this clinical trail. 23. Besides that, the patients who have difficulty to be participated in this clinical trial continuously by Principle Investigator (PI)'s decision. Exclusion criteria for Re-injection is except for 13-1) Re-injection date is followed by visit 7.
