  Purpose
To determine whether "continuous use" of celecoxib over a 6-month period is more efficacious than "usual or intermittent use" in preventing spontaneous osteoarthritis flares of the knee and hip.

Condition Intervention Phase
Osteoarthritis, Knee Osteoarthritis, Hip Drug: Celecoxib Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Double-Blind Parallel-Group Randomized Study Of Efficacy And Safety Of "Continuous Use" Of Celecoxib Vs. The "Usual Use" Of Celecoxib In The Treatment Of Subjects With Chronic Osteoarthritis Of The Hip Or Knee Who Require an Anti-Inflammatory Medication for Control Of Their Pain
