Overview

Retrospective study demonstrates improved functional and structural recovery after arthroscopic modified Broström repair for ligament injury, indicating preoperative morphology influences healing.

Key Points

  • To evaluate the relationship between preoperative MRI-based ligament characteristics and postoperative functional and imaging outcomes in patients undergoing arthroscopic modified Broström procedure with internal bracing for anterior talofibular ligament injuries.
  • Retrospectively analyzed 100 patients with confirmed anterior talofibular ligament injuries who underwent arthroscopic modified Broström repair with internal bracing.
  • Evaluated functional status using American Orthopaedic Foot and Ankle Society scores and measured radiographic talar tilt angle and anterior talar translation up to 6 months postoperatively.
  • Categorized preoperative ligament morphology as wavy-shape or discontinuity on MRI and evaluated structural healing and T2-weighted signal intensity at 6 months.
  • Both ligament morphology groups demonstrated statistically significant postoperative improvements in functional AOFAS scores, talar tilt angles, and anterior talar translation (P < .05).
  • At 6 months postoperatively, all evaluated ligaments regained a continuous linear band structure on MRI, and 64.9% (63 of 97) exhibited low T2-weighted signal intensity.
  • Patients with preoperative ligament continuity achieved a significantly higher prevalence of mature, low T2-signal intensity at follow-up compared to those with ligament discontinuity (80.9% vs. 50.0%, P < 0.05).
