Does anatomic single-bundle ACL reconstruction using hamstring autograft produce anterolateral meniscal root tearing?

Area of Science:

• Orthopedic surgery
• Sports medicine
• Radiology

Background:

• Anatomic single-bundle anterior cruciate ligament (ACL) reconstruction using hamstring autograft is a common procedure.
• Potential complications, such as anterolateral meniscal root injury, require investigation.

Purpose of the Study:

• To assess the risk of anterolateral meniscal root injury following tibial tunnel reaming during ACL reconstruction.
• To evaluate the diagnostic utility of magnetic resonance imaging (MRI) for detecting this specific injury.

Main Methods:

• Retrospective review of 104 primary ACL reconstructions using hamstring autograft.
• Radiological assessment of pre- and post-operative MRIs (>1 year follow-up) for lateral meniscus extrusion (>3 mm).

Main Results:

• No cases of anterolateral meniscal root injury were identified in the reviewed patient cohort.
• The study found no radiological evidence of this specific meniscal injury.

Conclusions:

• Tibial tunnel reaming in this ACL reconstruction technique does not appear to cause anterolateral meniscal root injury.
• MRI follow-up exceeding one year post-operation did not reveal any instances of this complication.
