Precision Assessment of Platelet Rich Plasma for Joint Preservation
Recruiting
I'm InterestedTrial ID: NCT03460236
Purpose
Knee Osteoarthritis (OA) is a leading cause of premature disability in Veterans who develop
knee OA at higher rates and younger ages than the population in general. For those with
symptomatic early knee OA, who are years to decades away from meeting clinical indications
for knee replacement surgery, knee injections have been a key treatment option. In recent
years, platelet rich plasma (PRP) injections have gained increasing attention for improving
pain and function in patients with knee OA. Basic science studies also suggest that PRP may
also potentially stimulate repair responses to articular cartilage. However, the mechanisms
of action of PRP in the treatment of knee OA are unknown. Because autologous blood is used,
the PRP composition differs between patients. It is also unknown whether these differences in
PRP composition affect clinical outcomes. This study will address these gaps and provide
critical new and objective information on PRP treatment effects in Veterans and additional
women with early knee OA important to improving clinical use of this new treatment.
