The prevalence of chronic low back pain (CLBP) is increasing. Treatment is effective in less than 50% of patients after 1 year. This review investigates new treatments for CLBP. An extensive literature review focuses on new treatments for CLBP. Their safety and efficacy were evaluated and are described in detail in this review. The investigation identified new treatments for CLBP including chemonucleolysis, platelet-rich plasma injections, artemin, tanezumab, and stem cells. Further research and innovation are needed to implement these methods into practice and assess clinical significance...

PURPOSE: Covered stents have been demonstrated to reduce restenosis; however, the membrane's limited biocompatibility can still lead to thrombus formation. To obtain optimal surface hemocompatibility, endothelialization of the luminal surface has been proposed. However, the effect of delivery procedures, such as crimping and balloon dilatation, on the endothelial layer has not been quantified. This study investigated the impact of such procedures on endothelialized covered stents in vitro...

In the context of prevascularization strategies for tissue engineering purposes, co-culture systems consisting of outgrowth endothelial cells (OECs) and primary osteoblasts (pOBs) have been established as a promising in vitro tool to study regeneration mechanisms and to identify factors that might positively influence repair processes like wound healing or angiogenesis. The development of autologous injectable platelet rich fibrin (PRF), which can be generated from peripheral blood in a minimal invasive procedure, fulfils several requirements for clinically applicable cell-based tissue engineering strategies...

INTRODUCTION: Haemophilic synovitis is caused by chronic accumulation of blood in the joint. Conservative treatment is insufficient to solve this pathology. Platelet-rich plasma (PRP) has a high concentration of growth factors (GFs) that play a key role in regulation and stimulation of healing processes. The aim of this study was to describe the effect of PRP injection in chronic synovitis of the joints in patients with haemophilia (PWH). PATIENTS AND METHODS: Nineteen patients with 28 joints were treated at our centre in Buenos Aires, Argentina between December 2014 and December 2015...

OBJECTIVES: After an injury, the biological reattachment of tendon to bone is a challenge because healing takes place between a soft (tendon) and a hard (bone) tissue. Even after healing, the transition zone in the enthesis is not completely regenerated, making it susceptible to re-injury. In this study, we aimed to regenerate Achilles tendon entheses (ATEs) in wounded rats using a combination of kartogenin (KGN) and platelet-rich plasma (PRP). METHODS: Wounds created in rat ATEs were given three different treatments: kartogenin platelet-rich plasma (KGN-PRP); PRP; or saline (control), followed by histological and immunochemical analyses, and mechanical testing of the rat ATEs after three months of healing...

Knee pain is commonly seen in orthopedic and rehabilitation outpatient clinical settings. Patients with knee osteoarthritis (OA) are often complicated with joint soreness, swelling, weakness, and pain. These complaints are often caused by the excessive amount of synovial fluid (SF) accumulated in the bursae around the knee joint. This study was aimed to evaluate the effectiveness of platelet rich plasma (PRP) in treating patients with minor to moderate knee osteoarthritis (OA) combined with supra-patellar bursitis using a proteomic approach and clinical evaluation tool...
