Disease modifying approaches are commonly applied in OA patients. An aging society with better life expectancies is increasing in Europe and the globe. Orthobiologics cover intraarticular hyaluronan injections and also cellular therapies. Cellular therapies range from platelet rich plasma (PRP) applications to exosomes. Short term follow-up of limited number of patients revealed favorable results in clinical cellular therapies. Most of these studies evaluated decrease of pain and increase in function. Recent basic science studies focused on the action mechanism of orthobiologic therapies however patient perspective is less studied. Our research team has recently performed a qualitative study on the patient perspective of hyaluronan injection of the knee joint. Findings of that study will be shared and future patient knowledge based options on orthobiologics will be discussed

The goal of surgery for osteochondral lesions is to regenerate the damaged cartilage with ideally hyaline cartilage. The current gold standard treatment is bone marrow stimulation (BMS) by microfracture. In reality however BMS typically results in the generation of fibrocartilage. Orthobiologics including bone marrow aspirate, platelet rich plasma and hyaluronic acid products have been shown to promote cartilage healing and potentially increase the formation of hyaline cartilage in treated lesions. However the role of these products, the timing of their administration and frequency of application are still not clearly defined and their routine use is still not recommended. These issues and future directions for research and future clinical application will be discussed

Geriatric syndromes could lead individuals to exhibit significant mobility and psychological deficits resulting in significant healthcare costs. Thus, identifying strategies to delay aging, or prevent progressive loss of tissue homeostasis could dramatically restore the function and independence of millions of elderly patients and significantly improve quality of life. One of the fundamental properties of aging is the accumulation of senescent cells and senescence associated secretory phenotypes (SASPs) that needs to be treated in wide range of therapeutics including orthobiologics. Senolytic compounds selectively target and kill senescent cells and inhibit anti-apoptotic pathways that are upregulated in senescent cells thereby inducing apoptotic cell death and abrogating systemic SASP factors. We have also shown that blocking fibrosis with Losartan (TGF-β1 blocker) can improve musculoskeletal healing and cartilage repair by reducing the amount of fibrosis. Thus, we hypothesize that administration of anti-fibrotic agents will enhance the beneficial effects of orthobiologics. The safety and efficacy of several senolytic and anti-fibrotic agents to delay age-related dysfunction and improve the function of orthobiologics have been demonstrated in a variety of animal models (in vivo). Overall, our innovative approaches target senescent cells (inflammation) and TGF-β1 (fibrosis) to enhance the clinical efficacy and use of orthobiologics for musculoskeletal repair. We will also discuss ongoing active clinical trials on orthobiologics to aiming at evaluating the safety and efficacy of senolytic agent (Fisetin) and anti-fibrotic agent (Losartan), used independently or in combination, to enhance the beneficial effects of orthobiologics for patients afflicted with musculoskeletal diseases and conditions.
