You may qualify if…

• Chronic OA of target knee confirmed by ACR Criteria
• Pain due to OA in target knee present for at least 6 months:
• Moderate to severe pain score of 41 mm to 90 mm recorded on a 100 mm VAS immediately following a 50-foot walk
• A bilateral standing AP X-ray confirming OA of the target knee-obtained within a 6-month period prior to the Screening Visit-and a grade of 2 or 3 according to the Kellgren and Lawrence Grading Scale
• Ability and willingness to use only acetaminophen as the analgesic (rescue) study medication
• The acetaminophen dose must not exceed 4 grams/day (4000 mg)
• If subject has known chronic liver disease, the maximum dose of acetaminophen must not exceed 2 grams/day (2000 mg)
• The subject must be willing and able to discontinue acetaminophen at least 24 hours prior to all study-specific visits
• The study specific acetaminophen provided will only be used for knee pain.
• Ability to perform procedures required of the pain index evaluations (unassisted walking 50 feet on a flat surface and going up and down stairs).
• Willingness and ability to complete efficacy and safety questionnaires and ability to read and understand study instructions
• Signed study-specific Subject Informed Consent Form

You may not qualify if…

• Any major injury (including sports injuries) to the target knee within the 12 months prior to the Screening Visit
• Any surgery to the target knee within the 12 months prior to the Screening Visit, or surgery to the contralateral knee or other weight-bearing joint if it will interfere with knee assessments
• Prior articular procedures, such as transplants or ligament reconstruction to the target knee
• Inflammatory arthropathies such as rheumatoid arthritis, lupus arthropathy, or psoriatic arthritis
• Gout or calcium pyrophosphate (pseudogout) diseases that have flared within the previous 6 months prior to the Screening Visit
• X-ray findings of acute fractures, severe loss of bone density, avascular necrosis, and/or severe bone or joint deformity in the target knee
• Osteonecrosis of either knee
• Fibromyalgia, pes anserine bursitis, lumbar radiculopathy, and/or neurogenic or vascular claudication
• Significant anterior knee pain due to diagnosed isolated patella-femoral syndrome or chondromalacia in the target knee
• Significant target knee joint infection or skin disorder/infection within the previous 6 months prior to study enrollment
• Symptomatic OA of the hips, spine, or ankle, if it would interfere with the evaluation of the target knee
• Known hypersensitivity to acetaminophen, EUFLEXXA™, or Phosphate buffered saline solution
• Women of childbearing potential who are pregnant, nursing, or planning to become pregnant, and those who do not agree to remain on an acceptable method of birth control throughout the entire study period
• Recurrent medical history of severe allergic or immune-mediated reactions or other immune disorders
• Vascular insufficiency of lower limbs or peripheral neuropathy severe enough to interfere with the study evaluation
• Current treatment or treatment within the previous 2 years prior to the Screening Visit for any malignancy unless specific written permission is provided by the Sponsor (excluding basal cell or squamous cell carcinoma of the skin)
• Active liver disease based on liver profile of AST, ALT, and conjugated bilirubin >2 times the upper limit of normal
• Renal insufficiency based on serum creatinine >2.0 mg/dL
• Any clinically significant laboratory value based on clinical history that the Investigator feels may affect the study evaluation
• Any intercurrent chronic disease or condition that may interfere with the completion of the 6-month (or 12-month) follow-up of the study, such as liver disease, severe coronary disease, drug abuse, disordered mental state, or other clinically significant condition
• Current alcoholism, and/or any known current addiction to pain medications
• Any clinically significant finding that would place the patient at health risk, impact the study, or affect the completion of the study
• Any psychiatric illness that would prevent comprehension of the details and nature of the study
• Participation in any experimental drug or device study within the 6 months prior to the Screening Visit
