Primary purpose: TREATMENT

Brief summary: The main purpose of this study is to establish that etoricoxib 30 mg is safe and not inferior to celecoxib 200 mg in the treatment of the signs and symptoms of osteoarthritis in Korean patients. Given that the efficacy of etoricoxib vs. placebo in the treatment of osteoarthritis has been established, and that prescription drugs, such as celecoxib, are available for the treatment of pain associated with osteoarthritis in Korea, it would be inappropriate to subject patients with a flare of osteoarthritic pain to the placebo treatment for 12 weeks, and thus the study is designed as an active-comparator study.


Eligibility criteria: Inclusion Criteria:

* Patient is at least 40 years of age
* Clinical diagnosis of osteoarthritis of the knee for greater than 6 months based on clinical and radiographic criteria

* Patient is willing to avoid unaccustomed physical activity for the duration of the study and follow-up period
* With the exception of osteoarthritis, the patient is judged to be in good general health based on medical history, physical exam, and routine laboratory tests
* Patient is able to read, understand and complete study questionnaires, including questions requiring a visual analog scale (VAS) response
* Patient provides written informed consent for the trial
* For prior non-steroidal anti-inflammatory drug (NSAID) users only, the patient has a history of positive therapeutic benefit with NSAIDs and has taken an NSAID prior to study enrollment and at a therapeutic dose level prior to study enrollment (Visit 1)

* For prior NSAID users only, prior to randomization, and following discontinuation of NSAIDs during the washout period specified patients must satisfy the following 3 flare criteria: Minimum of 40 mm on patient reported Pain Walking on a Flat Surface (WOMAC Section A, Question 1); Increase of 15 mm on patient reported Pain Walking on a Flat Surface (WOMAC Section A, Question 1) compared to prestudy baseline recorded at Visit 1; and A worsening in Investigator Global Assessment of Disease Status of at least 1 category on a 5 category scale compared to Visit 1 recording
* For prior acetaminophen/paracetamol users only, patient has taken acetaminophen/paracetamol on a regular basis prior to study enrollment (Visit 1) and does not use NSAIDs for the treatment of osteoarthritis of the knee
* For prior acetominophen/paracetamol users only, at both Visits 1 and 2, patients must satisfy all of the following 3 criteria: Minimum of 40 mm on patient reported Pain Walking on a Flat Surface (WOMAC Section A, Question 1); Investigator Global Assessment of Disease Status as fair, poor, or very poor; and Minimum of 40 mm on Patient Global Assessment of Disease Status (100 mm

VAS)

Exclusion Criteria:

* Patient has a history of neoplastic disease
* Patient has a history of any illness, which in the opinion of the investigator, might confound the results of the study or pose additional risk to the patient
* Patient is, at the time of signing informed consent, a user of recreational or illicit drugs or has had a recent history (within the last 5 years) of drug or alcohol abuse or dependence
* Patients considered morbidly obese with a body mass index (BMI) ≥ 35 kg/m\^2
