Osteoarthritis (OA) is a common joint disease characterized by cartilage damage and degeneration. Traditional treatments such as NSAIDs and joint replacement surgery only relieve pain and do not achieve complete cartilage regeneration. Silk fibroin (SF) biomaterials are novel materials that have been widely studied and applied to cartilage regeneration. By mimicking the fibrous structure and biological activity of collagen, SF biomaterials can promote the proliferation and differentiation of chondrocytes and contribute to the formation of new cartilage tissue. In addition, SF biomaterials have good biocompatibility and biodegradability and can be gradually absorbed and metabolized by the human body. Studies in recent years have shown that SF biomaterials have great potential in treating OA and show good clinical efficacy. Therefore, SF biomaterials are expected to be an effective treatment option for promoting cartilage regeneration and repair in patients with OA. This article provides an overview of the biological characteristics of SF, its role in bone and cartilage injuries, and its prospects in clinical applications to provide new perspectives and references for the field of bone and cartilage repair.

In situ articular cartilage (AC) regeneration is a meticulously coordinated process. Microfracture has been the most extensive clinical approach in AC repair, but it faces challenges such as matrix degradation, generation, and remodeling within a local inflammatory microenvironment. So far, it remains a challenge to establish a multistage regulatory framework for coordinating these cellular events, particularly the immune response and chondrocyte proliferation in microfracture-mediated AC repair microenvironments, which is crucial for promoting AC regeneration quality.

Introduction: Aberrant biomechanical force-induced chondrocyte adipogenesis is involved in the development of temporomandibular joint osteoarthritis (TMJ OA). Growth differentiation factor 11 (GDF11) has been implicated in this process. However, whether mechanosensitive histone deacetylase 3 (HDAC3) regulates GDF11 signaling in the context of TMJ OA remains to be elucidated.

Due to the poor regeneration ability of cartilage tissue, the design and fabrication of permanent hydrogel cartilage scaffolds with mechanical properties matching is still an urgent challenge. In this study, we propose an "inner swelling-outer restraint" strategy to construct Janus hydrogel for pressure-bearing cartilage replacement, which is inspired by the "Lamina-splendens" structure of cartilage. As a proof of concept, the poly(vinyl alcohol)/carboxymethyl cellulose sodium (PVA/CMCNa) layer is designed to capture more fluid by introducing negatively charged aggregates, while the macromolecular conformation of the PVA/MoS layer can be densified through wet annealing, thereby increasing the liquid permeation resistance of the PVA/CMCNa layer.

Stem cell-based tissue engineering offers transformative solutions for regenerating damaged tissues, such as bone, cartilage, and neural tissues. Chitosan and cellulose nanoparticles have emerged as promising biomaterials for enhancing stem cell delivery and scaffold performance due to their biocompatibility, biodegradability, and tunable properties. Chitosan, with its antimicrobial and bioadhesive properties, supports stem cell adhesion and differentiation in soft tissue scaffolds.

Electrosensitive hydrogels are smart biomaterials that swell, shrink, deform, and bend when an external electric field is applied. These hydrogels have enormous potential for the controlled therapeutic delivery of biochemical substances to the affected area, thus promoting tissue regeneration. Computational modeling and simulation approaches have provided researchers with cost-effective predictive models that can be used to optimize and experimental protocols.
