Editorial Commentary: The Benefits of Three-Dimensional Computed Tomography Images to Evaluate the Safety of All-Inside Meniscal Repair.

All-inside meniscal repair is a useful alternative to inside-out repair, particularly for the posterior horn of the lateral meniscus, because open approach to the complex posterolateral corner can be avoided. However, risk to the neurovascular structures is a major concern, and surgeons must be aware of portal placement, degree of penetration, patient size, and patient positioning. Imaging studies may be misleading, as they are generally obtained with the knee in extension. In the future, advanced imaging by 3-dimensional computed tomography may better allow us to preoperatively plan for a safe approach to the posterior horn of the lateral meniscus using all-inside repair techniques.
