Meniscal Tears

Abstract

A meniscal tear is any break in the continuity of the surface of the medial or lateral meniscus. Meniscal tears may occur in isolation or in association with a ligament injury or fracture. The mechanism of injury usually involves a twisting maneuver or a rapid change in direction on a weight-bearing knee. Degenerative tears may occur from activities of daily living. The diagnosis can be made through a careful patient history, physical examination, and plain radiography. If necessary, an MR image can be obtained. Arthroscopy is the accepted standard for diagnosis of meniscal pathology. Management includes nonsurgical and surgical treatment options; these include: observation, trephination, meniscectomy, meniscal repair, meniscal allograft transplantation, or meniscal replacement with collagen scaffold.
