Additional Effects of Steroid and Dextrose to Hyaluronic Acid on Knee Osteoarthritis

Additional Therapeutic Effects of Triamcinolone to Hyaluronic Acid on Knee Osteoarthritis: a Double-blind, Randomized-controlled Clinical Trial

Using double-blind, randomized controlled design to compare the immediate, short-term and intermediate-term additional therapeutic effects of ultrasound-guided corticosteroid injection and dextrose injection of hyaluronic acid injection on patients with knee osteoarthritis, under the basis of International Classification of Functioning, Disability, and Health.

A total of 60 patients will be collected. The participants will be randomized into two groups, including hyaluronic acid combined corticosteroid group and hyaluronic acid combined dextrose group. The balance, physical activity (10 meters normal and fast walk, up and downstairs, and 5 repeated chair-rising time, timed up and go test), functional performance and knee-related quality of life (Western Ontario and McMaster Universities Osteoarthritis index、Knee Injury and Osteoarthritis Outcome Score) will be evaluated. All the evaluations will be re-evaluated at one week after injection, one month after injection, three months after injection, and six months after injection. Subjects and evaluators will be both blinded to the group's classification during the whole course of study.

compare the effects of steroid plus hyaluronic acid and destrose plus hyaluronic acid on knee osteroarthritis

compare the immediate effect (one week after 3 times of injections), short-term effects (one month and three months after 3 times of injections), and midterm effect (6 months after 3 times of injections).

changes of scores from baseline to at one week, one month, 3 months and 6 months after 3 times of injections; score range: 0-100, higher scores mean a worse outcome

changes of scores from baseling to at one week, one month, 3 months and 6 months after 3 times of injections; score range 0-4, higher scores mean a better outcome

changes of scores from baseline to at one week, one month, 3 months and 6 months after 3 times of injections; score range 0-100, higher scores mean at better outcome

changes of scores from baseline to at one week after 1 time of injection and two weeks after 2 times of injection; the lower values indicate a low blood vessel resistance

Inclusion Criteria: clinical diagnosis of knee osteoarthritis can walk for 15 meters Kellgren-Lawerence grade 2 or greater than 2 can follow up for 6 months Exclusion Criteria: major diseases will affect balance, such as stroke, infectious diseases, rheumatoid arthritis, dizziness, or vertigo fractures malignance pregnancy or prepare to pregnant received knee injections in the past 6 months previous operation of knee joints
