Articular cartilage damage is predominantly caused by trauma, osteoarthritis (OA), and other pathological conditions. The limited intrinsic capacity of cartilage tissue to self-repair necessitates timely intervention following acute injuries to prevent accelerated degeneration, leading to the development of planar arthritis or even osteoarthritis. Unfortunately, current therapies for articular cartilage damage are inadequate in effectively replacing or regenerating compromised cartilage due to the absence of suitable tissue-engineered artificial matrices. However, there is promise in utilizing hydrogels, a category of biomaterials characterized by their elasticity, smooth surfaces, and high water content, for cartilage regeneration. Recent advancements in hydrogel engineering have focused on improving their bioactive and physicochemical properties, encompassing innovative composition designs, dynamic modulation, and intricate architectures. This review provides a comprehensive analysis of hydrogels for articular cartilage repair, focusing on their innovative design, clinical applications, and future research directions. By integrating insights from the latest research studies and clinical trials, the review offers a unique perspective on the translation of hydrogels for articular cartilage repair, underscoring their potential as promising therapeutic agents.
