Study summary

The aim of this clinical trial study is to compare the efficacy of Hyaluronic injection in patients with symptomatic knee osteoarthritis. The main questions it aims to answer are:

  • Is Hyaluronic acid injection improve pain symptom, joint stiffness, and joint function in patients with knee osteoarthritis
  • Is Hyaluronic acid injection improve knee performance status and health-related quality of life in patients with knee osteoarthritis

Participants will be allocated to receive one treatments; either Hyaluronic acid or normal saline injections after receiving glucocorticoid injection.

Researchers will compare the Hyaluronic acid with normal saline injection to see if the former show superior effect in terms of pain, joint stiffness, function, as well as health-related quality of life comparing with placebo.

Read the detailed description

Participants who had been diagnosed with knee osteoarthritis according to American College of Rheumatology (ACR) criteria will be enrolled in this study. After the participants receive the information and consent to participate in this study, they will be examined their affected knee by the co-researchers. Ten-milligrams of Triamcinolone will be injected intra-articular into knee joint.

Two-to-four weeks later, the participants will be evaluated for knee pain, stiffness, function and quality of life, as well as knee performance status. Participants whose their knee joint absence of effusion will be allocated in to one treatment group; either Hyaluronic acid or normal saline. After injection, participants will be scheduled for the follow-up visit in 12 and 24 weeks later. In each follow-up visit, they will be evaluated for joint pain, stiffness, function and quality of life, as well as analgesic use and adverse reaction form treatment.

What researchers measure

Primary outcomes

  1. Pain outcome measurement

    The comparison between Hyaluronic acid and normal saline injection in the change of joint pain after the injection, by using visual analog scale and pain domain assessment in Western Ontario and McMaster University (WOMAC) scale (scale 0-10, which higher scale reflects worse symptom)

    Time frame: 12 and 24 weeks after injection

  2. Joint stiffness and function measurement

    The comparison between Hyaluronic acid and normal saline injection in the change of joint stiffness and function after the injection, by using WOMAC scale (scale 0-10, which higher scale reflects worse symptom or function)

    Time frame: 12 and 24 weeks after injection

  3. Overall symptom assessment

    The comparison between Hyaluronic acid and normal saline injection in the change of overall symptom after the injection, by using patient's global assessment (scale 0-10, which higher scale reflects worse condition)

    Time frame: 12 and 24 weeks after injection

Secondary outcomes

  1. Knee performance evaluation

    The comparison between Hyaluronic acid and normal saline injection in the change of knee performance status after the injection, assessed by Time Up and Go test

    Time frame: 12 and 24 weeks after injection

  2. Quality of life assessment

    The comparison between Hyaluronic acid and normal saline injection in the change of health-related quality of life assessed by EuroQol group - 5 Dimensions - 5 Levels (EQ-5D-5L) tool (scale 0-100, which higher scale reflects better health)

    Time frame: 12 and 24 weeks after injection
