  • 1

    More rapid osteoarthritis development and an elevated risk of total knee arthroplasty.

  • 2

    It causes loss of hoop stress, outward meniscal extrusion, and increased tibiofemoral contact pressures.

  • 3

    “Patients demonstrating greater meniscal extrusion after repair experience significantly more radiographic osteoarthritis progression than those without post-repair extrusion.”.

  • 4

    Meniscal tissue integrity, including collagen fiber organization.

  • 5

    Highly organized circumferential fibers have short T2* values; disorganized or degenerated fibers have substantially longer values.
