Summary: The study presents the development of a periosteum mimicking bone aid (PMBA) with enhanced mechanical strength, tissue adhesiveness, and sustained activation of nitric oxide-cyclic guanosine monophosphate (NO-cGMP) signaling pathway for accelerated bone regeneration. This concept involves considering both the initial material components and the degradation products in promoting physiological activities, aiming to inspire the design of high-performance bioscaffolds for bone and periosteum tissue engineering.

Summary: The study demonstrates the crucial role of mesenchymal stromal cell-derived septoclasts in development and fracture healing, showing their disappearance after development completion and re-emergence during fracture healing. These septoclasts disappear in adult and ageing bones but reappear in association with growing vessels during fracture healing.

Summary: An ideal biomimetic periosteum is developed using a 4D printing technique to inlay aligned cell sheets on shape-shifting hydrogel, mimicking the natural periosteum's role in promoting bone repair. The outer hydrogel layer allows the biomimetic periosteum to digitally coordinate its 3D geometry to match the specific bone shape, while the inner aligned hMSCs layer promotes cell migration, angiogenesis, and osteogenic differentiation. In vivo experiments demonstrate that the aligned biomimetic periosteum can actively facilitate local angiogenesis and early-stage osteogenesis, providing a novel approach for constructing personalized biomimetic periosteum and repairing complex bone defects.

Summary: This study found that non-inflammatory chitosan coatings promoted cartilage infiltration into and over a bioplastic scaffold, and were compatible with trabecular bone integration. Compared to drill-only defects, the 83-99-PCL scaffold induced angiogenesis and slight bone resorption, with the smallest change in bone volume fraction.

Summary: The biomimetics of scaffolds in bone regeneration is crucial for promoting osteogenic differentiation. Changes in porous characteristics of scaffolds may affect their physicochemical and biological properties. Chitosan-based scaffolds have shown potential in promoting osteogenesis through supporting cell attachment and proliferation and the formation of mineralized bone matrix. This article discusses the correlation between porous properties of chitosan-based scaffolds and osteogenesis and angiogenesis, as well as methods to overcome the mechanical limitations of chitosan.

Summary: Despite the crucial role of osteoclast-to-osteoblast coupling in normal bone turnover, it appears to have limited relevance in bone healing, as shown in the study with CTR-deficient mice. Accelerated bone regeneration was not observed in the CTR-deficient mice, indicating that the specific involvement of the CTR-S1P axis may not significantly impact bone repair.

Summary: The periosteum plays a significant role in bone formation and regeneration by storing progenitor cells and acting as a source of growth factors. Tissue-engineered periosteum, produced using biomimetic methods, can significantly improve the efficacy of bone grafting and scaffold engineering. The development of bionic periosteum in tissue engineering aims to accelerate bone defect repair.

Summary: Bone tissue engineering is a promising approach for reconstructing bone defects, and metformin can enhance osteogenesis and angiogenesis. Vascular networks are crucial for bone tissue engineering, and metformin can also enhance vascular differentiation. This review article summarizes the effects of metformin on stem cells and bone tissue engineering, as well as its applications in bone repair.

Summary: Artificial periosteum of PLGA/MgO/Quercetin was prepared by electrospinning with highly porous surface and microstructure. The membrane showed excellent biocompatibility and promoted cell proliferation, migration, and osteogenic differentiation. It also facilitated angiogenesis of endothelial progenitor cells. In animal models, optimal osteogenesis and angiogenesis were observed for the PLGA/20 wt% MgO/0.1 wt% Quercetin membrane, indicating its potential for generating artificial periosteum.

Summary: Hemophilia is a monogenic mutational disease affecting coagulation factor genes, with recombinant clotting factors being the current preferred treatment. Advanced gene therapies show promise for a curative effect, but are associated with immunogenicity and hepatotoxicity that need to be optimized. It is important for both physicians and patients to understand the potential benefits and risks of new therapies, and to maintain a registry of gene therapy patients to track efficacy and long-term adverse events.

Summary: Knee osteoarthritis affects a significant part of the population, and current treatments often have only short-term benefits. Platelet-rich plasma (PRP) therapy has gained interest for its potential in treating knee OA, although the effectiveness remains controversial. Further research and studies comparing PRP with placebo are needed to confirm its efficacy.

Summary: The usual treatment for bone defects and recalcitrant nonunions is autogenous bone grafts, but limitations in procurement has led to the development of various bone healing materials. Synthetic bone graft substitutes, combined with bioactive molecules or stem cells, have been used to promote tissue ingrowth and bone regeneration. Further research is needed to investigate the efficacy of these treatments.

Summary: A literature search found that the rate of complications after TKA in people with hemophilia is high (ranging from 7% to 30%), although it has improved during the last two decades with better perioperative hematologic treatment. However, the prosthetic survival rate at 10 years has not substantially changed, remaining approximately 80% to 90% over the past 30 years. The survival rate at 20 years with revision as the endpoint is 60%. Precise perioperative control of hemostasis in people with hemophilia may reduce the percentage of complications after TKA.

Summary: Radiosynovectomy (RS) is an effective treatment option for recurrent articular bleeds related to chronic hemophilia synovitis (CHS) that cannot be controlled with medication. It can be performed in adolescents and adults, but may require general anesthesia in children. RS is a cost-effective alternative to surgical synovectomy, and chemical synovectomy with rifampicin can be utilized in areas where radioactive materials are not easily available. In cases of RS and/or chemical synovectomy failure, arthroscopic synovectomy may be indicated.

Summary: This narrative review examined the literature related to the risk of deep vein thrombosis (DVT) in people with hemophilia (PWH) after orthopedic surgery. It concluded that pharmacological thromboprophylaxis is generally not necessary for PWH, except in cases of major orthopedic surgery with additional VTE risk factors. Limited evidence suggests the use of low molecular weight heparins or direct oral anticoagulants in some PWH with risk factors for VTE.
