Low-Grade Inflammation in Musculoskeletal Disorders: Biological Basis and PRGF Role
| Journal | Rehabilitacion |
| Study Type | Clinical Study |
| Population | Human participants |
This study highlights the shift from viewing common musculoskeletal conditions as purely degenerative to understanding them as inflammatory processes, opening new therapeutic pathways. The recognition that chronic low-grade inflammation drives conditions like osteoarthritis and tendinopathies fundamentally changes how we approach treatment selection and patient counseling.
This clinical study examines the biological basis of chronic low-intensity inflammation in musculoskeletal disorders including tendinopathies, osteoarthritis, and intervertebral disc disease. The authors investigate plasma rich in growth factors (PRGF), a specific leukocyte-free platelet-rich plasma preparation, as a therapeutic intervention targeting the inflammatory cascade. The study identifies the regenerative potential of platelet-derived proteins and the fibrin matrix as key therapeutic mechanisms. However, the authors acknowledge significant variability in clinical outcomes attributed to patient-specific pathophysiology, product inconsistencies, and diverse application protocols.
“While the inflammatory paradigm for these conditions is compelling, I remain cautious about PRP therapies given the substantial variability in preparation methods and clinical protocols. The field needs standardized approaches before we can reliably predict which patients will benefit from these interventions.”

FAQ
What is PRGF and how does it differ from other PRP treatments?
PRGF (Plasma Rich in Growth Factors) is a specific type of platelet-rich plasma that contains no white blood cells and is activated with calcium chloride. Unlike other PRP preparations, PRGF’s leukocyte-free formulation may reduce inflammatory responses while maintaining regenerative benefits through platelet-derived proteins and the fibrin matrix.
Which musculoskeletal conditions can benefit from PRGF therapy?
PRGF shows promise for conditions involving chronic low-grade inflammation, including tendinopathies, osteoarthritis, and intervertebral disc disease. These conditions were previously considered purely degenerative but are now understood to involve inflammatory processes in structures like subchondral bone and vertebral endplates.
What therapeutic effects does PRGF provide for musculoskeletal disorders?
PRGF demonstrates multiple therapeutic properties including tissue repair, anti-inflammatory effects, immune system modulation, pain relief, and anti-fibrotic activity. These effects work through the regenerative potential of platelet-derived proteins, plasma biomolecules, and the dynamic fibrin matrix system.
Why do clinical outcomes with PRGF vary between patients?
PRGF treatment outcomes vary due to individual patient pathophysiology, differences in product preparation and quality, and variations in application protocols. Patient-specific factors and treatment standardization significantly impact therapeutic effectiveness.
How does the new understanding of inflammation change treatment approaches for “degenerative” conditions?
Recognizing chronic low-intensity inflammation as a key mechanism shifts focus from purely symptomatic treatment to addressing underlying inflammatory processes. This approach targets previously overlooked structures like subchondral bone in osteoarthritis and vertebral endplates in disc disease, opening new therapeutic avenues.
