Modifying Orthobiological PRP Therapies Are Imperative for the Advancement of Treatment Outcomes in Musculoskeletal Pathologies.

Autologous biological cellular preparations have materialized as a growing area of medical advancement in interventional (orthopedic) practices and surgical interventions to provide an optimal tissue healing environment, particularly in tissues where standard healing is disrupted and repair and ultimately restoration of function is at risk. These cellular therapies are often referred to as orthobiologics and are derived from patient's own tissues to prepare point of care platelet-rich plasma (PRP), bone marrow concentrate (BMC), and adipose tissue concentrate (ATC). Orthobiological preparations are biological materials comprised of a wide variety of cell populations, cytokines, growth factors, molecules, and signaling cells.

Regulatory Considerations of Orthobiologic Procedures.

The injection of biologic products for musculoskeletal pathologies is an emerging and promising field; however, dubious and unsafe uses for these products are often marketed. The Food and Drug Administration (FDA) has determined the need for varying degrees of regulation for these products for safety and efficacy. These regulations are frequently updated and federally enforced.

Mesenchymal stem cells for subchondral bone marrow lesions: From bench to bedside.

Subchondral bone marrow lesions (BMLs) are areas of disease within subchondral bone that appear as T1 hypointense and T2 hyperintense ill-defined areas of bone marrow on magnetic resonance imaging. The most common bone marrow lesions include subchondral lesions related to osteoarthritis, osteochondral defects, and avascular necrosis. Emerging therapies include autologous biologic therapeutics, in particular mesenchymal stem cells (MSCs), to maintain and improve cartilage health; MSCs have become a potential treatment option for BMLs given the unmet need for disease modification.

Amniotic dehydrated cell and protein concentrate versus corticosteroid in knee osteoarthritis: preliminary findings.

The purpose is to report preliminary data on clinical response to dehydrated cell and protein concentrate (dCPC) versus corticosteroid (CSI). A single-site prospective, randomized controlled single-blinded trial of patients with knee osteoarthritis. : Pain and function were assessed using a visual analog scale (VAS), the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Emory Quality of Life (EQOL) measure at 1, 2, 3, 6, 9 and 12 months.

NSAIDs Reduce Therapeutic Efficacy of Mesenchymal Stromal Cell Therapy in a Rodent Model of Posttraumatic Osteoarthritis.

Background: Intra-articular injections of human mesenchymal stromal cells (hMSCs) have shown promise in slowing cartilage degradation in posttraumatic osteoarthritis (PTOA). Clinical use of cell therapies for osteoarthritis has accelerated in recent years without sufficient scientific evidence defining best-use practices. Common recommendations advise patients to avoid nonsteroidal anti-inflammatory drug (NSAID) use before and after cell injection over concerns that NSAIDs may affect therapeutic efficacy.

American Medical Society for Sports Medicine Position Statement: Principles for the Responsible Use of Regenerative Medicine in Sports Medicine.

Many sports medicine physicians are currently considering introducing regenerative medicine into their practice. Regenerative medicine and the subclassification of orthobiologics are a complicated topic and have produced widely varying opinions. Although there is concern by government regulators, clinicians, scientists, patient advocacy organizations, and the media regarding the use of regenerative medicine products, there is also excitement about the potential benefits with growing evidence that certain regenerative medicine products are safe and potentially efficacious in treating musculoskeletal conditions.

Use of Bone Marrow Concentrate to Treat Pain and Musculoskeletal Disorders: An Academic Delphi Investigation.

Background: Acute and degenerative musculoskeletal disorders are among the most common etiologies of disability worldwide. Recently, there has been interest in the field of regenerative medicine to bridge the gap between conservative and surgical management of these conditions. Autologous bone marrow concentrate is one type of injectate that has increased in popularity over the last few decades.

Biologics.

Biologics are a growing field that has shown immense promise for the treatment of musculoskeletal conditions both in orthopedic sports medicine and interventional pain management. These procedures utilize injection of supraphysiologic levels of platelets and growth factors to invoke the body's own inflammatory cascade to augment the healing of many bony and soft tissue conditions. While many patients improve with conservative care, there is a need to address the gap between those that improve with rehabilitation alone and those who ultimately require operative management.

Platelet-Rich Plasma: New Performance Understandings and Therapeutic Considerations in 2020.

Emerging autologous cellular therapies that utilize platelet-rich plasma (PRP) applications have the potential to play adjunctive roles in a variety of regenerative medicine treatment plans. There is a global unmet need for tissue repair strategies to treat musculoskeletal (MSK) and spinal disorders, osteoarthritis (OA), and patients with chronic complex and recalcitrant wounds. PRP therapy is based on the fact that platelet growth factors (PGFs) support the three phases of wound healing and repair cascade (inflammation, proliferation, remodeling).

A Review of Current Management of Knee Hemarthrosis in the Non-Hemophilic Population.

The knee joint is one of the most frequently injured joints in the body, and the resulting injury may often lead to the presence of a bloody effusion, or hemarthrosis. The acute management of this condition can have long-lasting implications, and may ultimately result in the early onset of osteoarthritis in this population. Heme, a breakdown product of erythrocytes, and associated pro-inflammatory mediators, are known to have deleterious interactions with cartilage and synovium.
