Objective:
To review the methods and progress of arthroscopic reconstruction of anterior cruciate ligament (ACL) with the remnant preservation technique.
Methods:
Recent literature about arthroscopic reconstruction of ACL with the remnant preservation technique was reviewed and analyzed.
Results:
The preserved ACL after injuries could be single-bundle or remnant. The preserved remnant provided synovium for the reconstructed ACL, and it could accelerate revascularization of the graft, and it was benefit for the proprioception too, and certain kinds of remnant could contribute to the stability of the joint. The preserved remnant could prevent the washing-effect of the joint fluid, then prevent the enlargement of the tibial tunnel. Cyclops or impingement may occurred in remnant preservation technique.
Conclusion:
Remnant preservation in ACL reconstruction can provide good clinical result. But remnant preservation is a skill demanded technique. There should be more research and clinical trials about remnant preservation in ACL reconstruction about its necessity and advantage, also disadvantage.
