Overview

Cohort study shows progressive bone mineral density increases at tendon-bone interface after ACL reconstruction, indicating associations with graft maturation.

Key Points

  • Significant increases in volumetric bone mineral density recorded at femoral and tibial tunnel regions highlight healing progress.
  • Measurements at different time points showed femoral tunnel segments increased by +36.1% to +52.7% within 6 months post-surgery.
  • Observational assessments through quantitative computed tomography provided critical insights into tendon-bone healing.
  • Negative correlations suggest that BMD changes may reflect the maturity of grafts in their respective regions during recovery.
