Sumary of ACL reconstruction, lateral meniscus root repair technique used in a professional athlete:

  • Examination demonstrated a high-grade Lachman test, a large effusion and an otherwise stable knee.
  • In cases of ACL deficiency, the posterior root of the lateral meniscus has a significant contribution to lateral compartment joint reactive forces and secondarily controlling anterolateral rotatory instability (ALRI).
  • Therefore, in patients with severely unstable Lachman results and/or higher-grade pivot shifts, concomitant high-grade lateral meniscus injury/root deficiency should be suspected.
  • Vial and colleagues found 7.1% of primary ACL tears and nearly 40% of revision ACL tears have concomitant lateral posterior meniscal root tears.
  • The patient’s MRI demonstrated an ACL tear with increased signal intensity near the lateral root and a “ghost sign” on sagittal images.
  • The sensitivity and specificity of a “ghost sign,” when the meniscus is not visible posteriorly on sagittal images, for meniscal root tears are reported by S-H Choi and colleagues to be 96.7% and 96.7%, respectively.
  • However, only 33% of lateral root tears diagnosed arthroscopically are originally identified on preoperative MRI according to a study by Aaron J.
  • LaPrade, MD, and colleagues showed that tears and avulsions near the lateral root significantly increase contact pressures in the lateral compartment and that these contact pressures can be significantly improved with trans-tibial suture repair.
