Adipose-Based Therapies for Knee Pain —Fat or Fiction

J Knee Surg DOI: 10.1055/s-0038-1672155Regenerative cell therapies are emerging as promising treatments for numerous musculoskeletal conditions, including knee osteoarthritis (OA). Adipose-derived stem cells and possibly other adipose-based therapies have a greater chondrogenic potential than stem cells derived from bone marrow, and thus a lot of attention is being placed on them as potential regenerative agents in the treatment of knee OA. Several types of adipose-based therapies have good basic science and preclinical data supporting their translation to human therapeutic intervention. Cultured, adipose-derived stem cells appear to be good source of bioactive cells with convenient accessibility, relative abundance, and well-documented regenerative capacity. Non-culture expanded adipose-based therapy, in the forms of stromal vascular fraction and most recently micronized adipose tissue (MAT), have been utilized in patients to treat OA and other cartilage abnormalities with encouraging preliminary data. These adipose-based therapies have shown a lot of therapeutic potential; however, because of the regulatory restrictions on enzymatic isolation and cell expansion, only MAT is currently available in clinical practice in the United States. While no serious adverse reactions have been reported, adipose-derived therapies also have the potential for adverse reactions including inflammation and infection. The current review provides an update on the latest research and presents thi...

In this study, we analyzed the role of these cells in modifying the pathological microenvironment present in knee osteoarthritis. This is an interventional, prospective, randomized, controlled study. Starting from June 2017, 39 patients with grade III and IV knee osteoarthritis of Kellgren-Lawrence were enrolled, aged between 45 and 75 years, with pain greater than or equal to 6 according to the VAS scale, without ligament instability, with an axial deviation not greater than 10° and with a BMI between 18 and 30. The control group underwent an arthroscopic debridement, while the experimental group underwent an arthrosc...

Stem cell therapy has been studied for decades for its regenerative potency in various diseases. We investigated the safety and efficacy of intra-articular injection of placental mesenchymal stem cells (MSCs) in knee OA healing.MethodsIn th...

This article, however, is more of a commentary on high level strategy and the effects of regulation, coupled with a desire to forge ahead rather than hold back in the matter of treating aging, thus I concur with much more of what is said than is usually the case. For decades, one of the most debated questions in gerontology was whether aging is a disease or the norm. At present, excellent reasoning suggests aging should be defined as a disease - indeed, aging has been referred to as "normal disease." Aging is the sum of all age-related diseases and this sum is the best biomarker of aging. Aging and its d...

J Knee Surg DOI: 10.1055/s-0038-1676069With our aging population desiring to remain active, the incidence and costs associated with managing knee pain from both acute injury and symptomatic knee osteoarthritis continue to dramatically increase. Current treatment methods fall short with respect to their ability to improve the intra-articular environment and restore normal joint homeostasis. With increasing basic science and clinical evidence showing efficacy, cell-based therapies such as bone marrow concentrate (BMC) hold promise as a nonsurgical joint preserving treatment approach. BMC has inherent advantages over other tr...

Focal chondral defects of the knee are extremely common and often result in pain, dysfunction, joint deterioration, and, ultimately, the development of osteoarthritis. Due to the limitations of conventional treatments for focal chondral defects of the knee, orthobiologics have recently become an area of interest. Orthobiologics used for cartilage defects include (but are not limited to) bone marrow aspirate concentrate, adipose-derived mesenchymal stem cells, platelet-rich plasma, and micronized allogeneic cartilage. Each of these products can be applied in the clinical setting, as an isolated surgical procedure, or as an ...

Conclusions: Our results indicate that HOTAIRM1-1 is downregulated in OA cartilages, and its downregulation may inhibit MSCs viability, induce apoptosis and suppress differentiation via regulating miR-125b/BMPR2 axis. JNK/MAPK/ERK pathway may be a possible downstream mechanism to mediate the role of HOTAIRM1-1 in OA development.Graphical abstract

J Knee Surg DOI: 10.1055/s-0038-1675170With average life expectancy and the rising prevalence of obesity, osteoarthritis (OA) is creating an increasingly large financial and physical burden on the U.S. population today. As the body ages and experiences trauma, articular cartilage surfaces in joints are gradually worn away, leading to OA. Traditionally, treatment options have included lifestyle modifications, pain management, and corticosteroid injections, with joint replacement reserved for those who have exhausted nonsurgical measures. More recently, hyaluronic acid, micronized dehydrated human amniotic/chorionic membrane...

Authors: Khatab S, van Osch GJ, Kops N, Bastiaansen-Jenniskens YM, Bos PK, Verhaar JA, Bernsen MR, van Buul GM Abstract Mesenchymal stem cells (MSCs) represent a promising biological therapeutic option as an osteoarthritis (OA)-modifying treatment. MSCs secrete factors that can counteract inflammatory and catabolic processes and attract endogenous repair cells. The effects of intra-articular injection of MSC secretome on OA-related pain, cartilage damage, subchondral bone alterations and synovial inflammation were studied in a mouse collagenase-induced OA model. The MSC secretome was generated by stimulating human ...

Authors: ┼×ahin ┼×, Tuncel SA, Salimi K, Bilgiç E, Korkusuz P, Korkusuz F Abstract Osteoarthritis (OA) is a common form of arthritis, which is characterized by progressive degradation of joint cartilage resulting in pain, joint stiffness, deformity and disability that is also recently related to an increased incidence of mortality. Inhibition of the extracellular matrix (ECM) production by chondrocytes and accumulation of catabolic mediators associated with matrix degradation are the cause of OA. Nonsurgical treatments for OA can be characterised as symptom-modifying or disease-modifying approaches. It's est...
