Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-100 with moderate to severe shoulder pain due to glenohumeral osteoarthritis who have not responded to conservative treatments.

Probably not a fit

Patients with a history of prior PRP injections or recent steroid treatments may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of platelet-rich plasma (PRP) injections in treating glenohumeral osteoarthritis by comparing low-dose and high-dose PRP preparations against a saline control. Participants aged 18-100 with significant shoulder pain due to osteoarthritis will receive one of the three treatments after failing conservative therapies. The study aims to determine which PRP dosage provides better outcomes for patients suffering from this condition. MRI confirmation of joint issues and a history of pain are required for eligibility.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective pain relief option for patients with shoulder osteoarthritis.

How similar studies have gone: Previous studies have shown some efficacy of PRP in treating glenohumeral osteoarthritis, but this study's comparison of different PRP dosages is a novel approach.
