Landmark Review Defines Clinical Standards for PRP in Musculoskeletal Disorders
A scientific and clinical overview for pain physicians.
A 2025 narrative review published in the Journal of Clinical Medicine offers a data-driven framework for understanding the key biological components of effective Platelet-Rich Plasma (PRP) therapy. Drawing on evidence from over 200 clinical studies, the review outlines specific parameters associated with positive outcomes in musculoskeletal conditions, including osteoarthritis, tendinopathy, and soft tissue injury.
Rather than general recommendations, the review provides a structured comparison of PRP system profiles, focusing on biological dose, cellular composition, and preparation methods.

Summary of Key Parameters for Effective PRP
🔹 Platelet Dose: Clinical benefit is observed when individual PRP injections deliver 4 billion or more platelets. This threshold has been associated with improved pain scores and functional recovery across multiple studies.
🔹 Cumulative Delivery: For chronic joint disorders, total delivery of 10+ billion platelets over a treatment course appears to optimize therapeutic effect.
🔹 Cellular Composition (Leukocytes): Leukocyte-poor PRP (LP-PRP) demonstrated consistent clinical advantages in intra-articular use, particularly in reducing post-injection inflammation. This profile was favored over leukocyte-rich PRP (LR-PRP) in the context of joint preservation.
🔹 Red Blood Cell (RBC) Exclusion: PRP formulations that exclude RBCs are recommended for intra-articular applications. The presence of RBCs has been associated with local oxidative byproducts that may influence tissue response.
🔹 Presence of PBMNCs: PRP containing peripheral blood mononuclear cells (PBMNCs), including monocytes, lymphocytes, and macrophages, may offer additional benefit by supporting immune modulation and regenerative signaling pathways, including M2 macrophage polarization.
Clinical Focus: LP-PRP and PBMNC-Enriched Formulations
✅ LP-PRP for Joint and Soft Tissue Applications
- LP-PRP was highlighted as the preferred profile for intra-articular injections due to its favorable inflammatory response and improved functional outcomes.
✅ PBMNCs and Regenerative Signaling
- Monocyte presence in PRP is associated with biological pathways that contribute to soft tissue healing and immune resolution.
- Published trials (e.g., De Matthaeis et al., Saita et al.) show that PBMNC-enriched formulations correlate with improved VAS and WOMAC scores in patients with knee osteoarthritis.
Epimed Tropocells® PRP in Context
The review includes a comparative overview of PRP system parameters. Based on these outlined criteria, Tropocells® PRP is consistent with the formulations described as biologically appropriate for musculoskeletal applications:
✔️ Single-spin preparation with ≥4 billion platelets per injection
✔️ Leukocyte-poor profile (no neutrophils)
✔️ RBC-free final product
✔️ Preserves PBMNCs, including monocytes
✔️ Recovery efficiency of ~85%
These characteristics reflect the cellular and compositional framework associated with clinical benefit in the reviewed literature.
Conclusion
The 2025 Journal of Clinical Medicine review offers a detailed analysis of PRP systems through the lens of biological composition and clinical efficacy. As PRP continues to evolve in pain and musculoskeletal medicine, aligning treatment protocols with clearly defined parameters—dose, purity, and immune-active cell content—is key.

FAQ – section
1. What makes PRP biologically effective for musculoskeletal conditions?
Clinical studies reviewed in J Clin Med. 2025 highlight that biologically effective PRP should deliver ≥4 billion platelets per injection, be leukocyte-poor, free of red blood cells, and contain PBMNCs to support immune-mediated tissue repair.
- What is LP-PRP, and why is it preferred for joint injections?
Leukocyte-poor PRP (LP-PRP) excludes neutrophils and reduces post-injection inflammation. It is preferred for intra-articular injections in knee osteoarthritis, shoulder tendinopathy, and other joint conditions where excessive inflammation may impair recovery.
- Does Tropocells® meet the standards described in the 2025 review?
Yes. Tropocells® PRP is aligned with the criteria described in the Journal of Clinical Medicine review:
✔️ ≥4 billion platelets
✔️ LP-PRP profile (no neutrophils)
✔️ RBC-free
✔️ Preserves PBMNCs (monocytes, lymphocytes)
✔️ High recovery efficiency with a single-spin protocol
- What role do PBMNCs play in PRP efficacy?
Peripheral blood mononuclear cells (PBMNCs)—especially monocytes—are associated with regenerative signaling and M2 macrophage activation, which supports immune resolution and soft tissue healing.
- Is Tropocells® PRP suitable for pain management applications?
Yes. Tropocells® is widely used in interventional pain medicine for procedures including injections in osteoarthritis, rotator cuff tendinopathy, and other chronic musculoskeletal disorders. Its formulation supports biological consistency and clinical reproducibility.
