  • Ages 21 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The study population consisted of adult men and women aged 21 years and older with radiographically confirmed knee osteoarthritis (Kellgren-Lawrence grade 2-4). Participants were eligible if they were prescribed a single intra-articular injection of stabilized hyaluronic acid (DIART ONE or EASYGO ONE) as part of routine clinical care for synovial fluid deficiency. All participants had a Body Mass Index (BMI) between 18.5 and 35 kg/m². Individuals with other joint diseases, recent joint surgery, infections, or contraindications to hyaluronic acid were excluded.

Who may be able to join

  • Age ≥ 21 years.
  • Body Mass Index (BMI) ≥ 18.5 kg/m².
  • Body Mass Index (BMI) < 35 kg/m².
  • Presence of trauma or degenerative diseases (e.g., osteoarthritis) confirmed by radiographic imaging (Kellgren-Lawrence score 2-4).
  • The subject is prescribed an injection of stabilized hyaluronic acid (DIART ONE 20 mg/mL - 2 mL or 30 mg/mL - 3 mL) for temporary replacement of synovial fluid in the knee joint.
  • Signed written informed consent to participate in the study.

Who cannot join

  • Age < 21 years.
  • Body Mass Index (BMI) < 18.5 kg/m².
  • Body Mass Index (BMI) ≥ 35 kg/m².
  • Pregnancy or lactation.

About this study

Official title: Postmarketing, Prospective, Multicenter, Single-Arm Study of Subjects Who Receive an Injection of Medical Device Based on Hyaluronic Acid Marketed in Ukraine and Poland Administered Intra-Articularly to Patients Affected by Knee Osteoarthritis

This study looked at how safe and effective a hyaluronic acid-based injection (called DIART ONE or EASYGO ONE) is for people with knee osteoarthritis. The injection helps replace the natural fluid in the knee joint to reduce pain and improve movement. Patients received one injection, and their symptoms were tracked over 6 months using phone calls and clinic visits. The goal was to see how much pain and joint function improved, and to check for any side effects.

Read the detailed description

This was a post-marketing, observational clinical study designed to evaluate the safety, tolerability, and effectiveness of a single intra-articular injection of a stabilized hyaluronic acid-based medical device, marketed under the names DIART ONE (in Ukraine) and EASYGO ONE (in Poland). The study focused on adults diagnosed with knee osteoarthritis, a common joint disease that causes pain, stiffness, and reduced mobility due to the breakdown of joint cartilage and decreased synovial fluid.

A total of 55 participants were enrolled across multiple centers. Each participant received one injection of the investigational product into the affected knee. The specific formulation (either 20 mg/mL - 2 mL or 30 mg/mL - 3 mL) was selected by the treating physician based on clinical needs and product availability.

The primary goal of the study was to assess the change in pain levels 3 months after injection, using the WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) pain subscale, a validated questionnaire used to evaluate joint pain. Secondary outcomes included changes in pain at other time points (1, 2, 4, 5, and 6 months), as well as changes in joint stiffness and physical function.

Participants were monitored over a 6-month period through a mix of in-person and phone follow-ups. Adverse events, including any side effects related to the product or injection, were documented and analyzed.

What is being measured

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

  1. Change in the WOMAC Pain Subscale Score at 3 Months

    Mean change from baseline in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale score (5-point Likert-type scale, range 0-20) at 3 months after a single intra-articular injection of hyaluronic acid.

    Measured: 3 months after injection (Day 90 ± 5 days)

Secondary outcomes (1)
  1. Change in the Total WOMAC Score at 1, 2, 3, 4, 5, and 6 Months

    Mean change from baseline in the total WOMAC index score (Likert-type scale, total range 0-96: pain = 0-20, stiffness = 0-8, physical functioning = 0-68) at multiple time points following injection.

    Measured: 1, 2, 3, 4, 5, and 6 months after injection

Questions about this trial

What is this clinical trial studying?

An observational study of Knee Osteoarthritis and Osteoarthritis of the Knee, run by Yuria-Pharm at 1 site in Ukraine.

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 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Ukraine. Whether a site is taking part right now should be confirmed with that site. See every 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in the WOMAC Pain Subscale Score at 3 Months (time frame: 3 months after injection (Day 90 ± 5 days)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2025.
