Evidence brief

MARS:MARS Revision ACL Study

Multicenter ACL Revision Study (MARS) Group Outcomes

Authors
MARS Group, Wright RW, Huston LJ, et al
Journal
J Bone Joint Surg Am
Year
2014

Key Findings

  • 1

    Revision ACL has worse outcomes than primary

  • 2

    Meniscal status at revision critical for outcome

  • 3

    Allograft higher failure rate than autograft in revision

  • 4

    Tunnel position assessment essential

  • 5

    Staging may be necessary for bone loss

Clinical Implications

MARS data guides revision ACL surgery planning. Graft choice (autograft preferred), tunnel assessment, and meniscal status are key determinants of revision success.

Teaching Note

For revision ACL viva: Know failure modes (technical, biological, traumatic). Assess tunnels (CT scan), alignment, previous graft. MARS shows autograft superior for revision. Discuss staging for tunnel bone loss.
