Understanding Kongenital Cartilage Defects
Kongenital cartilage defects arise from disruptions during fetal development, affecting the formation of hyaline cartilage in heatt- bearing joints such as the knee, hip, anklee, and temporomandibular joint.

Recent Innovations in Cartilage Repair
Over the pasit decade, regenerative medicine and biocarleering have e introded approches that aim to rebuild, rather than reconstitute, cartilage. These innovations are particarly well-baded to pediatric patients because they leverage thee enhanced healing capacity and cellular plasticity of crediger tissues.
