Novel Orthobiologic Preparation and Regenerative Rehabilitation of a Complex Shoulder Injury in a Competitive Adolescent Female Athlete.

This is a single case report, so it cannot establish cause-and-effect or generalizability. Multiple interventions (BFR, PRP, prolotherapy, dry needling, collagen supplementation) were administered concurrently or sequentially, making it impossible to determine which component, if any, drove the improvement. The outcome measures (NPRS, Quick-DASH) were self-reported, and while imaging was used, the clinical exam findings at follow-up were not blinded. The authors state explicitly that the theoretical constructs do not indicate a cause-and-effect relationship and that results may not be seen in other subjects.

No conflicts of interest or funding sources were declared in the provided text.

Do not conclude that PRP or prolotherapy alone caused the recovery. The athlete received a complex package of treatments including blood flow restriction, dry needling, and collagen supplements, and the paper explicitly states that the contribution of any single component cannot be separated.
