A Phase 4 interventional study of Corticosteroid and Platelet Poor Plasma in Thigh Muscle Injury, Thigh Injury and Musculoskeletal, sponsored by Andrews Research & Education Foundation. Enrolling by invitation at 1 site in United States. Open to participants aged 15 Years to 30 Years. Per ClinicalTrials.gov, last updated 2026-10-29.
Sponsored by Andrews Research & Education Foundation · Phase 4, Interventional, and Treatment
The purpose of this study is to compare the number of days it takes for a sport participant to return to play between ultrasound guided intramuscular corticosteroid injections and platelet-poor plasma (PPP) injections for thigh muscle injuries.
Andrews Research & Education Foundation is the lead sponsor of 20 studies on the registry; 2 are open to participants now.
Of its 6 completed or terminated interventional studies of FDA-regulated products, 4 (67%) have results posted.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Drug: Corticosteroid
Biological: Platelet Poor Plasma
Only drug in the study
Only biologic in the study
Return to Play
Number of days required for a patient to resume full, unrestricted, and asymptomatic participation in sports following the injection.
Time frame: Up to 1 year
VAS Pain Scale
Visual Analog Scale (VAS) scores will be collected and analyzed at the following time points: immediately post-procedure, 24 hours, 2 weeks, 6 weeks, 12 weeks, and 1 year after the procedure. The Visual Analog Scale is a pain measurement to be obtained from the patient that ranges from 0 (no pain at all) to 10 (worst pain you can ever imagine).
Time frame: Up to 1 year
Modified BAMIC
A secondary endpoint of this study includes characterization of the thigh injury using a modified version of the British Athletics Muscle Injury Classification (BAMIC) system.
Time frame: Pre-Injection
Peak Strength
Comparison of peak strength between the injured and uninjured thigh using a digital handheld dynamometer at the time of return-to-play clearance
Time frame: Up to 1 year post-injection
