Subject has a history of Anterior cruciate ligament (ACL) repair, reconstruction or injury in the Index knee within 3 years of signing the ICF.~8. Subject has X-Ray findings of acute fractures, severe bone loss, avascular necrosis, severe bone or joint deformity in the Index knee.~9. Subject has significant varus or valgus deformity greater than 8 degrees in either knee.~10. Subject has a clinically apparent tense effusion of the Index knee.~11. Subject has knee instability in either knee per the Investigator's assessment.~12. Subject requires consistent use of an assistive device (e.g. wheelchair, walker, etc.) Occasional use of a cane is acceptable.~13. Subject has medical condition(s) which could affect study assessments or may adversely affect the safety and/or success of the study treatment. This includes but is not limited to the following: a. Peripheral neuropathy severe enough to interfere with evaluation of the subject, b. Vascular insufficiency severe enough to interfere with evaluation of the subject, c. Active fibromyalgia, d. Hemiparesis involving either lower extremity, e. Immunocompromised or immunosuppressive disorder or receiving medications to treat immunosuppressive disorders, f. Systemic bleeding disorder(s), g. Current malignancy or treatment within the last 5 years, except for non-melanoma skin cancer, h. Significant psychiatric disorder, i. Active drug and/or alcohol abuse within the past year, j. Uncontrolled diabetes with a Screening Hemoglobin A1C (HbA1c) of \>7% k. contraindication to Triamcinolone Hexacetonide (TH) including active tuberculosis, herpes simplex keratitis, acute psychoses and systemic mycoses and paracitoses.~14. Subject is taking medications at the time the subjects signs the ICF which could interfere with the treatment procedure, healing and/or assessments. This includes but is not limited to oral or injectable anticoagulant treatments, anti-aggregant platelet treatment, chronic opioid analgesics. Low dose aspirin used for cardiovascular protection is allowed if a stable regimen is maintained for the duration of the study.~15. Subject is receiving treatment using electromagnetic stimulation and/or low intensity ultrasound in the Index knee at the time of signing the ICF, within 3 months of signing the ICF or plans to receive treatment any time during the study period.~16. Subjects who had an oral, intramuscular, intravenous, rectal suppository or topical (excluded in Index knee only) corticosteroid within 30 days of signing the ICF are excluded. Topical corticosteroid use at any site other than the Index knee is allowed.~17. Subject has a pre-treatment contraindication to IA injections or aspiration of the Index knee, including cutaneous infection in the injection site area, active IA infection (as suggested by moderate or marked effusion), knee deformity or condition which, in the opinion of the Investigator could jeopardize the sterility or delivery of the IA injection.~18. Subjects with a history of hypersensitivity to any of the ingredients in the hyaluronan or previous hypersensitivity to the administration of corticosteroids or an inability to tolerate acetaminophen.~19. Subject has any contraindication to the receipt of a corticosteroid.~20. Subject is receiving or in litigation for worker's compensation.~21. Subject is a woman who is pregnant or breastfeeding at the Screening Visit or a woman of child bearing potential who refuses to use effective contraception during the course of the study.~22.

Subject previously treated with Cingal for knee osteoarthritis.~Baseline Exclusion Criteria 25. Subject has a decrease of ≥ 20 mm in the WOMAC pain-sub-score (average of 5 pain scales) from Screening to Baseline in the Index knee on a 100 mm Visual Analog Scale (VAS) scale.~26. Subject has a synovial fluid aspirate volume \> 10 mL in the Index knee. 27. Subject has a contraindication to continue with the study treatment injection based on the visual appearance of the synovial fluid aspirate unless the fluid is examined microscopically prior to injection with no clinically significant findings (e.g. bacteria, crystals or blood).~28. Subject has range of motion of less than 100° flexion in either knee.
