The landscape of meniscal injuries.

This article analyzes meniscal injuries seen in 10,117 knee arthroscopies. The information was compiled by a centralized data base at Surgical Data Management. The study suggests two patterns of meniscal injuries, degenerative and traumatic. Injuries to the menisci occurring with an associated anterior cruciate injury, radial tears, and tears within 3 mm of the meniscosynovial junction are associated with a younger and more active patient who is more likely to sustain a traumatic or sports-related injury. Tears described as complex, horizontal cleavage, and flap tears are associated with an older age group and follow a more degenerative pattern.
