Overview

Controlled laboratory study investigates arthrokinematics and cartilage composition post-ACLR+M, suggesting implications for PTOA development.

Key Points

  • Tibial translations increased during walking and jogging after ACLR with meniscal surgery, indicating joint movement changes.
  • Higher T1ρ relaxation times in femoral cartilage suggest altered composition in reconstructed knees compared to contralateral knees.
  • Analysis used dual-fluoroscopy and qMRI to assess joint motion and cartilage health in twelve participants after surgery.
  • Findings highlight early mechanical and compositional differences post-surgery, informing rehabilitation strategies for PTOA.
