Meniscal Extrusion

The concept of meniscal extrusion has recently been recognized as an important pathological condition associated with meniscal dysfunction. Meniscal extrusion is the medial or lateral displacement of the meniscus beyond the edges of the tibial plateau. Some meniscal extrusions are physiologic, but large degrees of extrusion are thought to be pathologic. Meniscal extrusion can vary in extent from minimal physiological extrusion to extrusions exceeding 10 mm. The generally accepted threshold value is considered to be 3 mm. To date, the gold standard for measuring meniscal extrusion is T2-weighted MRI. MRI is valuable not only due to its ability to define other meniscal or knee pathologies but also because it provides good sensitivity and specificity. Surgical treatment of meniscal extrusion is preferred in young, active, symptomatic patients and individuals with acute injuries. The treatment approach may vary depending on the underlying cause. One of these methods is centralization surgery, which aims to achieve the anatomical reduction of the extruded meniscus. The aim of this study is to compare the functional outcomes of transtibial pull-out and suture anchor techniques used in centralization surgery and to contribute to standardization.
