Meniscectomy
Despite recent advances in meniscal repair and a greater understanding of the functional role of the meniscus, the majority of symptomatic meniscal tears observed at arthroscopy remain irreparable. Meniscal tears may be simple radial, vertical/longitudinal, or horizontal in orientation. More complex patterns include displaced bucket-handle, parrotbeak, multiplanar, degenerative, and meniscal root tears. Tears most often involve the posterior horn of the meniscus. The work done to identify the vascularity of the meniscus has been helpful in classifying tears, with peripheral tears, or red-red tears, occurring in an area of good vascular supply. Red-white tears and the most central white-white tears have less vascular penetration.
