Comparison of Transtibial Pull Out Method and Suture Anchor Method in Surgical Treatment of Meniscus Extrusion

What this Trial Is About

Meniscal extrusion, where the meniscus moves beyond the edges of the tibial plateau, is an important condition linked to meniscal dysfunction. While some extrusion is normal, large displacements over 3 mm are considered pathological. Surgical treatment is often preferred for young, active patients with symptoms or acute injuries. This trial compares two surgical techniques, transtibial pull-out and suture anchor methods, to improve treatment standardization for meniscal extrusion. Participants will receive one of two surgical procedures: the transtibial pull-out method, which repairs the meniscus by restoring its hoop stress mechanism through a tibial tunnel, or the suture anchor method, which fixes the meniscal root directly using anchors without a tibial tunnel. Both techniques target posterior root tears, especially in the medial meniscus. The study will monitor patients over 12 months to assess outcomes. During the study, researchers will measure changes in meniscal extrusion using MRI images from enrollment through 12 months post-treatment. Functional outcomes will be assessed with scores such as the Lysholm score, Tegner activity score, and the International Knee Documentation Committee (IKDC) score at 3, 6, and 12 months. This follow-up aims to evaluate the effectiveness of each surgical technique on knee function and meniscus positioning.
