This study aims to evaluate the effectiveness and safety of intra-articular injections of hyaluronic acid conjugated with fibrinogen in patients with knee osteoarthritis. Knee osteoarthritis is a common degenerative joint disease that causes pain, stiffness, and reduced mobility, significantly affecting quality of life. Hyaluronic acid injections are widely used to relieve symptoms, but their effectiveness may be limited in some patients. Fibrinogen has potential biological effects that may enhance tissue repair and anti-inflammatory responses. In this single-arm clinical study, patients with knee osteoarthritis will receive intra-articular injections of hyaluronic acid conjugated with fibrinogen. Clinical outcomes, including pain relief, functional improvement, and adverse events, will be assessed during follow-up visits. The results of this study may provide additional evidence regarding the potential benefits and safety of conjugating hyaluronic acid with fibrinogen for the treatment of knee osteoarthritis.
This is a prospective, single-arm clinical study designed to evaluate the efficacy and safety of intra-articular hyaluronic acid conjugated with fibrinogen in patients with knee osteoarthritis. Eligible patients diagnosed with knee osteoarthritis according to clinical and radiographic criteria will be enrolled. All participants will receive intra-articular injections of hyaluronic acid conjugated with fibrinogen administered under sterile conditions. The primary objectives of the study are to assess changes in pain intensity and knee function following treatment. Secondary objectives include evaluation of functional outcomes, patient-reported quality of life, and the occurrence of adverse events related to the intervention. Patients will be followed for a predefined period after injection, during which clinical assessments will be performed at scheduled visits. Pain and functional outcomes will be evaluated using validated clinical scales. Safety assessments will include monitoring and recording of any local or systemic adverse events throughout the study period. This study is conducted as part of a doctoral research project in clinical pharmacology at the University of Medicine and Pharmacy at Ho Chi Minh City. The study protocol has been reviewed and approved by the Institutional Review Board of the University of Medicine and Pharmacy at Ho Chi Minh City prior to initiation.

RECRUITINGChange from baseline in WOMAC total score
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score is used to assess pain, stiffness, and physical function in patients with knee osteoarthritis. Scores range from 0 to 96, with higher scores indicating worse symptoms.
Time frame: Baseline, 2 weeks, 1 month, 3 months, 6 months, and 12 months
Change from baseline in pain intensity at rest measured by Visual Analog Scale (VAS)
Pain intensity at rest is assessed using the Visual Analog Scale (VAS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
Time frame: Baseline, 2 weeks, 1 month, 3 months, 6 months, and 12 months
Change from baseline in pain intensity during movement measured by Visual Analog Scale (VAS)
Pain intensity during movement is assessed using the Visual Analog Scale (VAS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
Time frame: Baseline, 2 weeks, 1 month, 3 months, 6 months, and 12 months
Change from baseline in Lysholm Knee Scoring Scale
The Lysholm Knee Scoring Scale is used to assess knee function. Scores range from 0 to 100, with higher scores indicating better knee function.
Time frame: Baseline, 3 months, 6 months, and 12 months
Change from baseline in physical health measured by SF-36 Physical Component Summary (PCS)
Physical health-related quality of life is assessed using the Short Form-36 Health Survey (SF-36) Physical Component Summary (PCS). Scores range from 0 to 100, with higher scores indicating better physical health.
Time frame: Baseline, 3 months, 6 months, and 12 months
Change from baseline in mental health measured by SF-36 Mental Component Summary (MCS)
Mental health-related quality of life is assessed using the Short Form-36 Health Survey (SF-36) Mental Component Summary (MCS). Scores range from 0 to 100, with higher scores indicating better mental health.
Time frame: Baseline, 3 months, 6 months, and 12 months
Radiographic severity of knee osteoarthritis assessed by Kellgren-Lawrence grading system
Radiographic severity of knee osteoarthritis is assessed using standard knee X-ray and graded according to the Kellgren-Lawrence grading system (Grade 0-4), with higher grades indicating more severe osteoarthritis.
Time frame: Baseline and 12 months
Incidence of adverse events following intra-articular hyaluronic acid-fibrinogen injection
Safety is assessed by the incidence, type, and severity of adverse events (AEs) and serious adverse events (SAEs) related to intra-articular injection of hyaluronic acid conjugated with fibrinogen. Adverse events include local reactions such as pain, swelling, joint effusion, and infection, as well as systemic adverse events occurring during the follow-up period.
Time frame: From baseline up to 12 months after intra-articular injection
