Study Details

Brief summary:

This is a single-center, prospective, randomized, single-blind, comparator therapy, parallel group study for symptomatic patients diagnosed with knee osteoarthritis. The aim is to demonstrate superior efficacy of platelet-rich plasma (PRP) as compared to hyaluronic acid (HA) in treating knee osteoarthritis. This aim will be objectively measured by endpoint consisting of changes in cartilage thickness from baseline in the MRI. The Knee Injury and Osteoarthritis Outcome Score (KOOS) Questionnaire will be used to calculate The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score. It will measure changes in pain and function from baseline. Approximately 100 subjects will be treated at NorthShore University HealthSystem (NorthShore) as part of this study. This study has the potential to improve outcomes in a very common chronic degenerative disease, osteoarthritis, which can have a significant effect on individuals' quality of life.

Interventions and Outcome Measures

Arms

experimental: PRP Treatment

PRP is injected using 22 gauge needles through the classic approach (lateral midpatellar) in a sterile setting. The PRP is obtained from a maximum 16 cc sample of the patients' blood drawn at the time of treatment. Using sterile technique, the venous blood is transferred to a centrifuge and prepared by the centrifugation process for 5 minutes. 4-7 mL of PRP is transferred from the large outer syringe into the small inner syringe and injected within 30 minutes of being spun to negate the need of anticoagulants. The procedure will take approximately 20-30 minutes.

active comparator: HA Treatment

HA is injected using 22 gauge needles through the classic approach (lateral midpatellar) in a sterile setting. Euflexxa will be prepared according to the package insert.

Interventions

PRP Treatment

PRP will be prepared using an Arthrex ACP® kit (a low-leukocyte Autologous Conditioned Plasma system). This is a single-spin system that concentrates platelets and separates red blood cells (RBCs) as well as white blood cells (WBCs) from the treatment product.

HA Treatment

Euflexxa will be used for treatment. It will be prepared according to the package insert.

Primary outcome measure

  • Cartilage Thickness on MRI [ Time Frame: 6 and 12 months ]
