Over 850,000 surgeries are performed to treat meniscal injuries each year in the United States. Even with repair, patients are likely to develop osteoarthritis (OA) within the next two decades. There is a pressing clinical need to improve meniscal repair procedures to restore tissue function and prevent joint degeneration later in life. Here we present a review of recently published articles (2020–2024) spanning basic science, translational, and clinical studies to highlight new advances in meniscus research across development, animal models, finite element models, and clinical interventions. Key progenitor cell populations and vascularity changes have been identified in human meniscus tissue development, aging, and degeneration with implications for novel tissue repair strategies. The use of animal and finite element models has expanded our understanding of meniscus tissue function and evaluated new therapies in preclinical studies. Further, advances in clinical diagnostics with machine learning models and surgical techniques have shed light on evidence-based practices for improving patient outcomes. We discuss across multiple length scales (micro-, meso-, macro-) the structure-function relationship of the meniscus in development and disease, recent advances in models and tools to study the meniscus, knowledge gaps in the field, persisting challenges in clinical treatments and assessments, and the translation of basic science therapies into the clinic.
