The knee meniscus: Structure-function, pathophysiology, current repair techniques, and prospects for regeneration

► The meniscus is a frequently injured fibrocartilage vital for knee function. ► Meniscus cells are heterogeneous and may be replaced using different cell sources. ► Innovative scaffold and scaffoldless approaches are used to engineer the meniscus. ► Various biochemical agents and mechanical bioreactors may enhance meniscus tissue.
