摘要

Objective

Refixation of anterior cruciate ligament (ACL) tears and augmentation using an Internal Brace® (Arthrex Inc., Naples, FL, USA) has become increasingly popular in recent years. The aim is to preserve the native ligament structure and, thus, improve clinical outcomes.

Indications

Indications are proximal ACL tears of Sherman type I and II in the acute phase postinjury. For multiligament injuries, internal brace augmentation can contribute to increased joint stability.

Contraindications

ACL refixation is not recommended for distal or middle segment tears and should not be delayed for more than 4 weeks posttrauma to ensure adequate healing.

Surgical technique

The rupture is bridged by an ultrahigh-molecular-weight polyethylene tape to reattach the ACL to the femoral footprint.

Postoperative management

Functional postoperative treatment involves partial weight-bearing of 15 kg on crutches within 3 weeks postoperatively. High-impact activities should be avoided for the first 6 months postoperatively.

Results

The clinical results of ACL augmentation with an Internal Brace® show a slightly increased re-rupture rate compared to ACL replacement, with good to excellent functional outcomes.
