Exclusion Criteria: * Premenopausal status (unless subject has had a hysterectomy). * Current use of any investigational drug. * Significant hematologic, renal, hepatic or cardiovascular disease (but not including mild/moderate hypertension) or any other serious medical condition that might preclude the subject's ability to participate fully in the project, keep clinic appointments, etc. * Prior surgery (including arthroscopy) of the contralateral knee. * Significantly abnormal laboratory values at the time of enrollment. * Pigmented villonodular synovitis of the knee. * Synovial chondromatosis. * Charcot arthropathy. * A known "secondary" cause of OA, including acute or chronic infectious OA; crystal-induced arthritis; systemic inflammatory connective tissue disease (e.g., rheumatoid arthritis, systemic lupus erythematosus); osteonecrosis; Paget's disease; or metabolic diseases, such as hemochromatosis, Wilson's disease, or ochronosis. Chondrocalcinosis, however, will not be an exclusion criterion. * Conditions other than knee OA which limit lower extremity function and mobility and/or would confound the evaluation of knee pain and function (e.g., clinically significant spinal or hip arthritis, painful or dysfunctional feet, peripheral vascular disease, lumbar radiculopathy, stroke, etc.). * Steroid injection into either knee within past 3 months. * A history of photosensitivity (sensitivity to light) or any other adverse reaction to a tetracycline. * Failure to pass a "faintness-of-heart" test (pre-randomization compliance test). * Prior chronic use of tetracycline (e.g., for severe acne). * Severe OA (Kellgren and Lawrence Grade IV) of the index knee. * Salicylate use, with a mean dose \>2g/d. * Institutionalization.
