• Sex: All
• Target Recruitment: 25

Inclusion Criteria

1. Age 18 years or older
2. Body Mass Index (BMI) ≤ 35 kg/m2
3. Diagnosis of symptomatic osteoarthritic joint in the index hip (Kellgren-Lawrence grade I to III) to be treated with CINGAL injection.
4. Failed conservative treatment for joint osteoarthritis.
5. NRS on walking ≥4 and ≤ 9 in index hip.
6. Subject must be willing to abstain from other treatments of the index hip for the duration of the study.
7. 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.
8. 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 assessment, the subject is willing to discontinue use of acetaminophen/paracetamol.
9. 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).
10. Able and willing to provide signed informed consent.

Baseline Inclusion Criteria

1. NRS pain on walking ≥4 and ≤ 9 in index hip

Screening

Exclusion Criteria

1. History of hypersensitivity to any of the ingredients in the hyaluronan or corticosteroids
2. Infection or skin disease in the area of the injection site or hip joint
3. NRS pain on walking > 3 the contralateral hip.
4. NRS pain on walking > 3 in the ipsilateral knee or ankle joints.
5. Subject received an injection of Hyaluronic Acid (HA) and/or steroid in either joint 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 joint during the course of this study.
6. Known inflammatory or autoimmune disorders (including rheumatoid arthritis, gout), or other pre-existing medical conditions that, in the opinion of the investigator, could impact treatment of the hip joint or affect the ability of the subject to accurately complete the study questionnaires and comply with the study requirements.
7. Subject is taking medications at the time of signing 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.
8. Subjects who had an oral, intramuscular, intravenous, rectal suppository or topical (excluded in index hip only) corticosteroid within 30 days of signing the ICF are excluded. Topical corticosteroid use at any site other than the index hip is allowed.
9. Significant trauma to the index hip within 26 weeks of screening
10. Chronic use of narcotics or cannabis.
11. Ligament instability or tear in index hip.
12. Diagnosis of fibromyalgia
13. Diagnosis of osteonecrosis in index hip
14. Subject has significant varus or valgus deformity greater than 10 degrees in either knee.
15. Subject requires consistent use of an assistive device (e.g. wheelchair, walker, etc.) Occasional use of a cane is acceptable.
16. Uncontrolled diabetes with HbA1c of >7%.
17. 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.
18. Subject is receiving or in litigation for worker's compensation.
19. Otherwise determined by the investigator to be medically unsuitable for participation in this study.

Baseline Exclusion Criteria

1. Subject has a decrease of ≥ 2 in the NRS pain on walking from Screening to Baseline in the index hip.
2. Subject has a contraindication to continue with the study treatment injection based on the visual appearance of the synovial fluid aspirate.

Arm && Interventions

Group	Intervention	Description
Cingal	Cingal	Single injection of Cingal into the hip joint of subjects diagnosed with osteoarthritis of the hip.

Primary Outcome Measures

Name	Time	Method
Numerical Rating Scale (NRS) Pain on Walking	6 months	Reduction of Index Hip Numerical Rating Scale (NRS) Pain on Walking from baseline to 6 months post injection was obtained from participant responses. The NRS Pain Score is an 11-point Likert scale ranged from 0 = No Pain to 10 = Worst Pain Level. A negative value for the change in NRS Pain Score indicates less pain post-treatment. A larger negative value indicates a higher level of improvement, and a better outcome.

Secondary Outcome Measures

Name	Time	Method
Lequesne Hip Index	6 Months	Improvement from baseline to 6 months in The Lequesne Hip Index. The Lequesne Hip Index is a three-section patient questionnaire that evaluates (1) pain or discomfort, (2) maximum distance walked, and (3) activities of daily living with 0 = best results / normal scores, to scores \>14 = extremely severe, to a maximum index score of 24 points.; A negative value for the change in Lequesne Hip Index indicates improvement. A larger negative value indicates a higher level of improvement, and a better outcome.
Patient Global Assessment (PGA) Score	6 Months	The change from baseline to 6 months in hip pain post-treatment as measured by the Patient Global Assessment (PGA) Score. PGA Score records participant responses to their assessment of how much their STUDY (treated) hip is bothering them today . The PGA Score is a validated 11-point Likert scale ranged from 0 = No Pain to 10 = Worst Pain.; A negative value for the change from baseline indicates improvement in PGA Score. A larger negative value indicates less pain, and a better clinical outcome.
The Outcomes Measures for Rheumatic Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) Responder Index. A Calculated Percentage (%) of Participants Responding to Treatment	6 Months	The post-treatment responder rate is determined through a calculation defined by the Outcomes Measures for Rheumatic Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) Responder Index. The OMERACT-OARSI Responder Index reports the percentage of subjects that met the criteria to be a good responder to treatment. The criteria for response are (1) improvement in pain or physical function \>50% and an absolute change \>20 mm; or (2) improvement of \>20% with an absolute change \>10 mm in at least of the following three categories: pain, physical function, and patient's global assessment.; A higher percentage of subjects responding indicates a better outcome.
Usage of Rescue Medication (Acetaminophen/Paracetamol). Number of Participants NOT Using Rescue Medication.	6 Months	The usage of Rescue Medication (RM) as based on the number of participants at 6 Months post treatment that were NOT using acetominophen/paracetamol RM for pain or discomfort.; A larger percentage of participants that were NOT using RM may correlate to a better clinical outcome in terms of pain.
