Exclusion Criteria

  19. Current or historical evidence of any clinically significant disease or condition, especially terminal stage cancer, poorly controlled diabetic mellitus (i.e., HbA1c > 8%), or neurological disease that, in the opinion of the investigator, may increase the risk of study treatment and TKA, or complicate the subject's post-operative course or interfere with the determination of pain intensity related solely to the TKA

  20. Subject with severe heart diseases (NYHA class-III and IV), with ischemic heart diseases (angina pectoris and myocardial infarction) and subject who underwent percutaneous transluminal coronary angioplasty (PTCA) or had treatments for coronary artery bypass graft within 6 months prior to screening

  21. With pre-existed psychiatric or neurological deficits, which may compromise the neurological toxicity evaluations in this study by the investigator's judgment

  23. With bone cancer within 5 years prior to screening

  24. Inability to understand or operate the PCA machine

  25. Female subject who is breast-feeding, pregnant, or planning to become pregnant
