Summary

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.

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.
