          -  Severe hip OA ipsilateral to the index knee

          -  Any pain that could interfere with the assessment of index knee pain (e.g. pain in any
             other part of the lower extremities, pain radiating to the knee)

          -  Any pharmacological or non-pharmacological treatment targeting OA started or changed
             during the 4 weeks prior to randomization or likely to be changed during the duration

               1. No IA injected pain medications in the study knee during the study

               2. No analgesics containing opioids. NSAIDs may be continued at levels preceding the
                  study and acetaminophen is available as a rescue medication during the study from
                  the provided supply

               3. No topical treatment on osteoarthritis index knee during the study

               4. No significant anticoagulant therapy (e.g. Heparin or Lovenox) during the study
                  (treatment such as Aspirin and Plavix are allowed)

               5. No systemic treatments that may interfere with safety or efficacy assessments
                  during the study

               6. No immunosuppressants

               7. No use of corticosteroids > 10 mg prednisolone equivalent per day (if ≤ 10 mg

Patient description (medical language): A 47-year-old woman comes to the office complaining of pain in the calf and knee when she bends down. The pain limits her activity. Her medical history is significant for osteoarthritis, for which she uses nonsteroidal anti-inflammatory drugs (NSAIDs) for the past two years. She is living with her husband and has 3 children. She doesn't smoke but drinks alcohol occasionally. Her vital signs are normal. On physical examination, there is a small effusion in the right knee. The effusion grew a little larger and she developed a tender swelling in the popliteal fossa and calf. Both the pain and swelling worsened as she bent and straightened her knee.

Patient description (patient's own words): I'm a 47-year-old woman, married with 3 kids. I don't smoke and I drink occasionally. I went to the doctor because of pain in my calf and knee when I was bending down. This has been limiting my daily activities. I have been diagnosed with osteoarthritis for which I have taken anti-inflammatory drugs for the past 2 years. The doctor saw a small fluid buildup in my right knee. This buildup became a bit bigger and I have a swollen calf. The pain is worse when I bend and straighten my knee.

Does the patient match the trial criteria? Entailment
