The Combination Effect of Platelet-rich Plasma and Hyaluronic Acid for Knee Osteoarthritis

Not Applicable
Completed
Conditions
Knee Osteoarthritis
Interventions
Drug: platelet rich plasma + Hyaluronic acid
Drug: platelet rich plasma + normal saline
Registration Number
NCT03290365
Lead Sponsor
Tri-Service General Hospital
Brief Summary

Although platelet rich plasma (PRP) and Hyaluronic acid (HA) are beneficial for osteoarthritis of knee (OA knee), the combined effect of PRP with HA was not clear so far. Hence, investigator assess a prospective randomized double-blind controlled trial.

Detailed Description

Patients with single or bilateral OA knee will be enrolled and randomized into intervention and control group. One dose of PRP is applied into both groups. One week later, one dose of HA is injected in intervention group and one dose of normal saline is injected in control group. Outcome measurements included visual analog scale (VAS)、Lequesne's severity index、Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)、balance test (Biodex) and analysis of synovial fluid at different follow-up frame (1st month, 3rd month, 6th month and 1 year after treatment).

Primary Outcome Measures
NameTimeMethod
Change from baseline in severity of symptoms and functional status on 1st month, 3rd month, 6th month and one year after injection.Pre-treatment, 1st month, 3rd month, 6th month and one year after injection.

Using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) to measure the symptoms and functional status before treatment and multiple time frame after treatment. Both subscales has the scores ranged from 1 to 5 for each item and a higher score indicating more severe of symptom or impaired functional status.

Secondary Outcome Measures
NameTimeMethod
Change from baseline of pain on 1st month, 3rd month, 6th month and one year after injection.Pre-treatment, 1st month, 3rd month, 6th month and one year after injection.

Using the Visual analog scale (VAS) to measure the pain scale before treatment and multiple time frame after treatment. The score ranging from 10 (remarkable pain) to 0 (no pain).

Change from baseline in severity of symptoms and functional status on 1st month, 3rd month, 6th month and one year after injection.Pre-treatment, 1st month, 3rd month, 6th month and one year after injection.

Using the Lequesne's severity index to measure the symptoms and functional status before treatment and multiple time frame after treatment. A higher score indicate more severe.

Change from baseline in balance function on 1st month, 3rd month, 6th month and one year after injection.Pre-treatment, 1st month, 3rd month, 6th month and one year after injection.

Using the balance test (Biodex) to measure the balance function before treatment and multiple time frame after treatment.

Change from baseline in analysis of synovial fluid on 6th month and one year after injection.Pre-treatment, 6th month and one year after injection.

The synovial fluid is aspirated to measure the parameters before treatment and multiple time frame after treatment.
