Although total meniscectomy had been performed as a treatment of meniscal tear, many published articles reported progression of the degeneration process in the articular cartilage and development of the osteoarthritis after meniscectomy. With the increased knowledge of the biomechanical properties of the meniscus, meniscal repair has been performed increasingly to maintain the important functions of the meniscus. Outside-in, inside-out, all-inside technique have been used as meniscal repair methods. In this review, indications, operative technique, and outcomes of the all-inside meniscal repair are discussed.
