- Lateral meniscus posterior root (LMPR) repair during ACL reconstruction restores knee stability to levels comparable with isolated ACL reconstruction.
- The study involved 41 patients undergoing ACLR with LMPR repair and 20 matched controls with isolated ACLR, showing similar improvements in pivot shift and KT-1000 stability tests post-operatively.
- Patient-reported outcome measures (PROMs) improved significantly in all groups, with no significant differences between the LMPR repair group and isolated ACLR controls.
- LMPR healing rates were high, with 75.6% complete healing and 24.4% partial healing, and no failures, independent of tear patterns (oblique radial, longitudinal/T-type, avulsion).
- Lateral meniscus extrusion (LME) decreased post-operatively, though it remained slightly higher in the LMPR group, but tear morphology did not significantly affect LME reduction, healing, or stability outcomes.
- The presence of MRI parameters like the lateral femoral notch sign (LFNS) or posterior meniscofemoral ligament (pMFL) was not associated with tear type or differences between LMPR repair and control groups.
