    Quadriceps tendon autografts show elevated MRI signal intensity at 3 and 6 months post-ACL reconstruction, normalizing by 12 months.

  • 2

    The study involved 19 young amateur athletes aged 13 to 19 who underwent primary all-inside QT autograft reconstruction.

  • 3

    MRI scans were performed at four time points: pre-surgery, 3 months, 6 months, and 12 months postoperatively.

  • 4

    Significant differences in signal intensity were noted in the proximal regions of the graft during early healing.

  • 5

    Limitations include a small sample size, lack of histologic validation, and absence of clinical outcome assessments.
