Abstract (original English)

Musculoskeletal disorders involving bone and cartilage remain a major clinical burden because these tissues have limited intrinsic regenerative capacity, and conventional orthopedic treatments often fail to restore durable structural and functional outcomes. Advances in musculoskeletal tissue biology have clarified the complex cellular, molecular, immunological, and biomechanical regulators of healing, forming a strong foundation for the development of next-generation regenerative therapies. Emerging strategies, including orthobiologic preparations, stem cell-based interventions, biomimetic and smart biomaterial scaffolds, nanotechnology-driven platforms, and three-dimensional bioprinting, have demonstrated improvements in matrix synthesis, angiogenesis, and inflammatory modulation in preclinical models and early clinical studies, with recent advances also showing improved control of cell differentiation, enhanced scaffold integration, and more precise tissue architecture. Clinical evidence suggests benefits, including enhanced fracture healing, improved repair of cartilage defects, and symptomatic relief in early osteoarthritis. However, outcomes remain variable due to heterogeneity in biologic preparations and study designs. Despite these advances, major challenges persist, including variability in biologic preparations, limited long-term clinical evidence, difficulties achie
