About this study

Official title: Hyaluronans in the Treatment of Ankle Osteoarthritis

The aim of this study was to investigate the efficacy and safety of three weekly intraarticular injections of Hyaluronate (HA) in patients with unilateral ankle Osteoarthritis (OA).

Read the detailed description

Viscosupplementation with 3 to 5 weekly hyaluronate injections is a well-established treatment option in knee osteoarthritis. Previous studies reported that five weekly hyaluronate injections were safe and effective for the treatment of ankle osteoarthritis. However, the effect of three weekly injections has rarely been investigated. Besides, no study to date has assessed whether balance function would change after HA injections in patients with ankle OA. The purpose of this study was to evaluate the efficacy and safety of three weekly injections of sodium hyaluronate (Hyalgan) in patients with unilateral ankle osteoarthritis. Pain, physical function and balance will be assessed as parameters for the effectiveness.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in the Ankle Osteoarthritis Scale (AOS) Score at 6 Months

    The AOS is a patient-rated, validated outcome measure that includes nine items on a pain subscale and nine items on a disability subscale. Using the AOS, a score of 0 represent no pain or disability and 10 represent worst pain or disability imaginable

    Measured: baseline and 6 months

Secondary outcomes (6)
  1. The American Orthopedic Foot and Ankle Society (AOFAS) Ankle/Hindfoot Score

    The American Orthopedic Foot and Ankle Society (AOFAS) ankle/hindfoot score is a 100-point scale that devotes 40 points to pain, 50 points to function and 10 points to alignment. The maximum score of 100 points denotes no pain and normal function and alignment

    Measured: 6 months

  2. Ankle Sagittal Range of Motion

    Ankle sagittal ROM is the sum of ankle dorsiflexion and plantar flexion angles.

    Measured: 6 months

  3. Four Clinical Balance Tests

    Single-leg stance test (SLS),The Functional Reach Test (FRT),Timed " Up-and-Go" test (TUG) ,Berg Balance Scale (BBS)

    Measured: 6 months

  4. the Level of Global Satisfaction Based on a 7-point Categorical Scale

    The rating was based on a 7-point categorical scale weighted from completely satisfied, satisfied, somewhat satisfied, no change, somewhat unsatisfied, unsatisfied to completely unsatisfied.

    Measured: 6 months

  5. Systemic and Local Adverse Events Recording

    he occurrence of systemic and local adverse events, defined as any unwanted events whether it was thought to be related to the study drugs or not, were recorded on a diary card

    Measured: 6 months

  6. Rescue Acetaminophen Consumption

    The use of all analgesic medication during the study period was recorded on a diary card by the patient.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing sodium hyaluronate in people with Osteoarthritis, run by Kaohsiung Veterans General Hospital. at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Jun 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Change From Baseline in the Ankle Osteoarthritis Scale (AOS) Score at 6 Months (time frame: baseline and 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00918736, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
