Intervention model description: Subjects are randomized in a 4:4:1 ratio into the Cingal, Monovisc (hyaluronic acid) or TH (triamcinolone hexacetonide) arms.
Primary purpose: TREATMENT

Brief summary: This is a multi-center, randomized, double-blind, parallel group, active comparator controlled trial to evaluate the efficacy and safety of a single injection of Cingal for the relief of joint pain in subjects with OA of the knee.

Detailed description: Cingal 16-02 is a multi-center, randomized, double-blind, active comparator controlled study designed to evaluate the relative contributions of the individual constituents (Hyaluronic Acid and Triamcinolone Hexacetonide) in the Cingal combination product to pain relief as measured by the change in WOMAC Pain from baseline through 26 weeks.

3. Subject has had at least two signs and at least two symptoms of OA disease (based on the European League Against Rheumatism (EULAR) recommendations for diagnosing knee OA) in the index knee for at least 6 months despite conservative treatment (weight reduction, physical therapy, pain medications, etc.). The EULAR signs and symptoms are as follows:

   * Signs: crepitus, restricted movement and bony enlargement
   * Symptoms: persistent knee pain, limited morning stiffness and reduced function
4. Subject must be willing to abstain from other IA treatments of the knee for the duration of the study.
5. Subject is willing to discontinue all analgesics including NSAIDs, except acetaminophen/paracetamol, at least seven days before the treatment injection and through the completion of the study.
6. Subject is willing to use only acetaminophen/paracetamol (up to a maximum of 4.0 grams per day per the package insert) for the treatment of joint pain for the duration of the study. At least forty eight hours prior to the Baseline Visit and each follow-up visit, the subject is willing to discontinue use of acetaminophen/paracetamol.
7. Subject is willing to maintain a stable dose of oral glucosamine and/or chondroitin sulfate products throughout the study, if taken prior to signing the informed consent form (ICF).
8. Subject is able to understand and comply with the requirements of the study and voluntarily provides consent.

Screening Exclusion Criteria:

1. Subject received an IA injection of Hyaluronic Acid (HA) and/or steroid in either knee within 6 months of signing the informed consent form (ICF). A subject will be excluded if they are planning to receive an HA or steroid injection (other than the study injection) in either knee during the course of this study.
2. Subject had an arthroscopy of either knee within 3 months of signing the ICF.
3. Subject had an open surgical procedure of either knee or hip or any surgery of the spine within 12 months of signing ICF. Subject plans to have knee, hip or spine surgery within the study period.
4. Subject has intra-articular trauma to the index knee. Subject has concurrent multi-system or multi-limb trauma.
5. Subject has evidence or medical history of the following diseases in the index knee: septic arthritis; inflammatory joint disease; history of Reiter's syndrome; gout; chondrocalcinosis associated with recurrent episodes of acute synovitis of the knee consistent with pseudogout; osteochondritis dissecans, Paget disease of the bone; ochronosis; acromegaly; hemochromatosis; primary osteochondromatosis; known history of Wilson disease; heritable disorders or collagen gene mutations.
6. Subject has a history of cartilage repair surgery in the index knee within 3 years of signing the ICF.
7. Subject has a history of 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 10 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.
