The Comparison of Knee Osteoarthritis Treatment With Single-dose of Bone Marrow Aspirate Concentrate, Single-dose of Leukocyte Rich Platelet Rich Plasma and 3 Injection of High Molecular Weight Hyaluronic Acid-A Randomized Clinical Trial
The Comparison of Knee Osteoarthritis Treatment With Single-dose of Bone Marrow Aspirate Concentrate, Single-dose of Leukocyte Rich Platelet Rich Plasma and 3 Injection of High Molecular Weight Hyaluronic Acid-A Randomized Clinical Trial
The aim of this study is to compare therapeutic and clinical effects of intra-articular injection of Bone Marrow Aspirate Concentrate (BMAC), inta-articular injection of Leukocyte Rich Platelet Rich plasma (LR-PRP) and 3 weekly doses of high molecular weight of Hyaluronic acid for the treatment of osteoarthritis (OA) of the knee ( KL scale II-IV).
Osteoarthritis (OA) is the most common joint disease worldwide, affecting an estimated 10% of men and 18% of women over 60 years of age with the knee and hip joints predominantly involved. The pain and loss of function can be debilitating; in developed countries the resultant socioeconomic burden is large costing between 1, 0% and 2, 5% of gross domestic product. Several therapeutic options for the treatment of OA are widely used, consists of pain management, physical therapy with life-modifying recommendations, joint injections with joint replacement for end-stage disease. Intra-articular drug delivery has several advantages over systemic delivery, including increased local bioavailability, reduced systemic exposure, fewer adverse events and reduced cost. Three injectable materials have been widely used for intra-articular treatment of the knee OA: corticosteroids (with or without local anesthetics), hyaluronic acid based preparations and in the last decade biologic preparations, such as human serum albumin, TNF and Il-1 inhibitors, platelet-rich plasma (PRP) injections, bone marrow-derived stem cells (BMSCs), adipose-derived stem cells (ADSCs) and amnion-derived mesenchymal stem cells (AMSCs) etc PRP is promising therapeutic option for the OA treatment, there are still many concerns with PRP's efficiency. Among all questions, ( Number of platelets, percentage in accordance with baseline, frequency of doses etc.) presence or absence of different cells in PRP formulations ( as leukocytes), could significantly change an overall clinical result. In general, PRP could be Leukocyte-rich (LR- with increase number of Leukocytes in comparison with baseline number) and Leukocyte-poor.
Another option that has become more popular for physicians treating this debilitation condition is BMAC, which use undifferentiated cells found in the bone marrow to promote healing and tissue regeneration. These cells have the ability to replicate into a multiple different tissue types. With BMAC, the marrow is concentrated provide better healing of the damaged tissue and aid in growth and repair. The full benefits of BMAC are still unknown, but studies have shown the treatment can reduce swelling, relieve pain, and improve healing in articular cartilage and bone grafts.
Autologous BMAC has shown promising clinical potential as a therapeutic agent in regenerative medicine, including the treatment of osteoarthritis and cartilage defects, and the clinical efficacy platelet rich plasma has been documented to alleviate symptoms related to knee osteoarthritis. However, randomized, prospective comparison of the two techniques has not been reported in the literature and long term follow-up for both treatments is limited, and especially limited in the use of BMAC for the knee OA treatment.
From the other hand, HA preparations are widely used in everyday practice for almost 30 years with variable results. No one of these therapeutic options are not yet recommended by supreme professional organizations ( e.g.AAOS) because of paulacity of scientific data and unbiased confirmation of their clinical efficiency with a broad advice for necessity of more rigorous clinical trials.
