Summary
Combined anterior cruciate ligament reconstruction and lateral extra-articular procedures can cause tunnel convergence. This technical note presents a modified technique using a knotless suture anchor to prevent graft damage and failure in knee surgery.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Reconstruction
Background:
- Increasing use of combined anterior cruciate ligament reconstruction (ACLR) and lateral extra-articular procedures (LEAP).
- Documented risk of tunnel convergence with combined ACLR and LEAP techniques.
- Tunnel convergence can lead to graft damage and subsequent graft failure.
Purpose of the Study:
- To describe a modified technique for performing lateral extra-articular tenodesis.
- To demonstrate how to avoid knee tunnel convergence in combined ACLR and LEAP.
- To present a method utilizing a knotless suture anchor.
Main Methods:
- Description of a modified Lemaire extra-articular tenodesis.
- Application of a knotless suture anchor technique.
- Focus on preventing tunnel convergence during combined ACLR and LEAP.
Main Results:
- The described technique aims to mitigate tunnel convergence.
- Successful avoidance of graft impingement or damage is anticipated.
- Potential for improved outcomes in combined ACLR and LEAP procedures.
Conclusions:
- The modified Lemaire technique with a knotless anchor offers a solution to tunnel convergence.
- This approach may reduce the risk of graft failure in combined ACLR and LEAP.
- Provides a valuable technical refinement for orthopedic surgeons.
