Meniscal Injuries in Active Patients

he menisci of the human knee are fibrocartilaginous, crescent-shaped structures that lie on the articular surface of the tibia (Figure 1). They are integral components of knee biomechanics. Injuries to the knee menisci are common, especially among athletes. Short-term sequelae of meniscal injury include knee pain and deficits in knee range of motion. Long-term sequelae may include degenerative changes in the knee joint with associated pain and stiffness. This article addresses the anatomy and function of the normal and injured meniscus, clinical diagnosis of meniscal tears, radiographic evaluation, and nonoperative as well as surgical treatment options.
