Objective:

To evaluate whether pre-repair meniscal T2* values are associated with medial meniscal extrusion after MMPRT repair and to compare T2* values before and after repair with those of age- and sex-matched healthy controls. The authors hypothesized that patients would retain elevated T2* values relative to controls at both time points.

Approach:

Study design and participants: Prospective study enrolling consecutive adults with MRI- and arthroscopy-confirmed complete medial meniscus posterior root tears, along with age- and sex-matched healthy controls.
Imaging: Patients underwent clinical 7-T MRI before and after repair; controls underwent one examination. A 3D multi-echo gradient-recalled echo sequence was used for quantitative T2* mapping.

Interpretation:

The provided source excerpt describes the study rationale, hypotheses, and methods but does not report results.
