Arthroscopic technique: two-piece excision of discoid meniscus.

This article describes a new arthroscopic technique of excision of complete discoid meniscus with a tear in which the discoid is divided into anterior and posterior pieces for removal. It is easy to perform because an excellent visualization of the posterior segment is obtained after removal of the anterior piece. The extent of intrasubstance pathology can be evaluated with a transverse cut to the mid portion of the discoid, and therefore, it is easy to determine the width of the rim to be retained. Because the meniscus is divided into two pieces, a large portal is not required for removal.
