This book, published in cooperation with ESSKA, provides an exhaustive review of the meniscus and its pathology, covering all aspects from the basic science of the normal meniscus to clinical and imaging diagnosis, meniscus repair and meniscectomy, outcomes and complications, postoperative management, and emerging technologies. The book opens by examining in depth aspects such as anatomy, histology, physiology, biomechanics, and physiopathology. Clear guidance is offered on arthroscopy and the classification of meniscal lesions, with consideration of the full range of meniscal pathology, including traumatic lesions, degenerative lesions, root tears, meniscal cysts, and congenital lesions. Choice of treatment in different settings is explained, and the various surgical techniques - meniscectomy, meniscal repair, and reconstruction with allografts - are described in detail with the aid of accompanying videos and with presentation of long-term results. The concluding chapter takes a look into the future of meniscus reconstruction, for example through regeneration using mesenchymal stem cells.
