Arthroscopic direct meniscal extrusion reduction: surgical tips to reduce persistent meniscal extrusion in meniscal root repair.

Meniscal extrusion (ME) is defined as extension of the meniscal margin by at least 3 mm beyond the tibial margin. The main purpose of meniscal root repair is to restore the anatomy and function of the meniscus. Therefore, the reduction in the ME is one of the important objective outcomes. Nevertheless, the reduced meniscal extrusion was obtained in limited patients after meniscal root repair. This technical note described the arthroscopic direct meniscal extrusion reduction as surgical tips to reduce persistent meniscal extrusion in posterior meniscal root repair.
