PRP vs Corticosteroid Injections for Shoulder Osteoarthritis
(PRP Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares two treatments for shoulder osteoarthritis: platelet-rich plasma (PRP) injections, which may aid tissue healing, and corticosteroid injections (also known as steroid or cortisone injections), which can reduce pain in the short term. Researchers aim to determine which treatment is more effective for active individuals with ongoing shoulder pain from mild to moderate osteoarthritis that hasn't improved with standard care. Participants must not have had recent shoulder injections or surgeries and should not have diabetes or other specific health conditions. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.
Do I need to stop my current medications for the trial?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking narcotics.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that platelet-rich plasma (PRP) injections are generally safe and can improve joint movement and reduce pain in people with osteoarthritis (OA). Some studies suggest that PRP might be more effective than other treatments, like hyaluronic acid, for easing symptoms over time. Most people tolerate PRP well, though some side effects can occur. The most common is an infection at the injection site, but this is rare.
Corticosteroid injections also manage pain and swelling in shoulder OA. They provide short-term relief but do not address the root cause of joint problems. Risks include possible damage to nearby tendons.
Overall, both treatments have been studied for safety, but PRP shows promise for longer-lasting benefits in joint health compared to corticosteroids.12345Why are researchers excited about this trial's treatments?
Researchers are excited about platelet-rich plasma (PRP) injections for shoulder osteoarthritis because they offer a regenerative approach, using components from your own blood to potentially repair tissues. Unlike the standard corticosteroid injections, which primarily reduce inflammation and pain temporarily, PRP leverages growth factors to stimulate healing at the cellular level. Furthermore, PRP may provide longer-lasting relief with fewer side effects, making it an appealing alternative for those seeking more sustainable outcomes.
What evidence suggests that this trial's treatments could be effective for shoulder osteoarthritis?
Research shows that platelet-rich plasma (PRP) injections can reduce pain and improve movement in people with joint problems. Studies have found that PRP significantly eases pain and boosts mobility for those with shoulder arthritis. One study showed pain levels improved by about 49% after six months and 45% after a year. In this trial, participants will receive either PRP injections or corticosteroid injections. PRP has proven more effective than steroid injections for improving shoulder function in the short term. PRP contains substances that help repair tissues, which might explain its positive effects.13678
Are You a Good Fit for This Trial?
This trial is for men and women aged 18-70 with shoulder pain from mild to moderate osteoarthritis that hasn't improved with standard treatments. They must not have had recent injections or surgery in the affected shoulder, be pregnant, or have conditions like diabetes, fibromyalgia, chronic fatigue syndrome, or a history of bad reactions to PRP or corticosteroids.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive either corticosteroid or platelet-rich plasma injections
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- Corticosteroid Injection
- Delayed Platelet Rich Plasma Injection After Corticosteroid Injection Failure
- Platelet Rich Plasma Injection
Trial Overview
The study compares three non-surgical treatments for shoulder osteoarthritis: Platelet Rich Plasma (PRP) injection, Corticosteroid injection, and delayed PRP after Corticosteroid failure. It aims to find out which treatment might best help young active people avoid surgery by improving tissue healing.
How Is the Trial Designed?

Experimental Treatment
Active Control
Minimum 2cc Leukocyte Poor Platelet Rich Plasma
If a participant does not have any benefit from the corticosteroid injection by the six-week follow-up time point, then that participant will be eligible for a platelet rich plasma injection.
5cc Normal Saline + 2cc 10 mg/ml Triamcinolone Acetonide (Kenalog)
Corticosteroid Injection is already approved in European Union, United States, Canada for the following indications:
- Acromioclavicular joint pain
