Wrisberg Rip:
The Wrisberg Rip is a characteristic longitudinal tear of the posterior horn of the lateral meniscus that may be seen in association with ACL tears. This tear type is important for two reasons. First, many people realize that meniscal tears are common in association with ACL disruption, but tears at the central portion of the posterior horn laterally are among the most frequently missed. The Wrisberg Rip is one of those tears. Second, because the Wrisberg Rip appears to occur only in association with ACL tears, this tear pattern may be used as a secondary sign of ACL disruption.
