Transtibial Pull Out Method Versus Suture Anchor Method for Meniscus Extrusion

April 30, 2025 updated by: Muhammet Celik, Ataturk University

Comparison of Transtibial Pull Out Method And Suture Anchor Method in Surgical Treatment of Meniscus 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Transtibial Pull Out Method
Procedure: Transtibial Pull Out Method
The Transtibial Pull-Out Repair is a surgical technique used to fix posterior root tears of the meniscus, particularly in the medial meniscus. This method restores the hoop stress mechanism of the meniscus, which is essential for knee stability and function.
Active Comparator: Suture Anchor Method
Procedure: Suture Anchor Method
The Suture Anchor Technique is an alternative to the Transtibial Pull-Out Method for repairing posterior meniscal root tears, especially in the medial meniscus. Instead of using a tibial tunnel, this technique fixes the meniscal root directly to the native footprint using suture anchors.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in the amount of meniscus extrusion in MR images.
Time Frame: From enrollment to the end of treatment at 12 months
determine the change in the amount of meniscus extrusion in preoperative and postoperative 12th month MR images.
From enrollment to the end of treatment at 12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Lysholm score
Time Frame: From enrollment to the end of treatment at 3, 6 and 12 months.
The Lysholm score is a 100-point scoring system for examining a patient's knee-specific symptoms including mechanical locking, instability, pain, swelling, stair climbing, and squatting.
From enrollment to the end of treatment at 3, 6 and 12 months.
Tegner activity score
Time Frame: From enrollment to the end of treatment at 3, 6 and 12 months.
The scale is numbered on a "0-10" format, with 10 being international soccer, and one being a person who is disabled from knee issues.
From enrollment to the end of treatment at 3, 6 and 12 months.
International Knee Documentation Committee (IKDC) Score
Time Frame: From enrollment to the end of treatment at 3, 6 and 12 months.
The IKDC is a patient-completed tool, which contains sections on knee symptoms (7 items), function (2 items), and sports activities (2 items). Scores range from 0 points (lowest level of function or highest level of symptoms) to 100 points (highest level of function and lowest level of symptoms).
From enrollment to the end of treatment at 3, 6 and 12 months.
