Deep lateral extra-articular tenodesis (LET) is associated with improved tibial internal rotational stability and favourable patient-reported outcomes compared with superficial LET in high-grade pivot-shift male patients undergoing quadrupled hamstring autograft ACL reconstruction.

Key Points

• The research aims to assess the effectiveness of deep lateral extra-articular tenodesis (LET) compared to superficial LET in improving tibial stability and patient outcomes after ACL reconstruction.
• Conducted level 1 randomized controlled trials
• Involved patients undergoing quadrupled hamstring autograft ACL reconstruction
• Measured tibial internal rotational stability and patient-reported outcomes
• Ensured adequate statistical power with narrow confidence intervals
• Deep LET resulted in significantly improved tibial internal rotational stability compared to superficial LET
• Patients reported better outcomes with deep LET after surgery
• Follow-up indicated over 80% retention for analysis
