摘要

The ideal graft choice for anterior cruciate ligament reconstruction (ACLR) remains a topic of debate. Although the quadriceps tendon (QT) autograft was first described in 1984, its use has only recently gained popularity. The QT autograft has favorable biomechanical properties compared to bone-patellar tendon-bone (BPTB) and doubled hamstring (HS) grafts. The QT graft can be harvested with or without a bone plug, using either a full-thickness or partial-thickness technique, and can even be obtained through minimally invasive procedures. However, surgeons must be mindful of potential risks, such as patellar fractures or insufficient graft length. Short-term studies have shown comparable outcomes to BPTB and HS autografts, with similar graft failure rates and patient-reported results. One key advantage of QT ACLR is lower donor-site morbidity compared to BPTB. Nevertheless, some reports have noted persistent quadriceps weakness following QT ACLR. Overall, current research indicates that QT autografts offer similar clinical outcomes to other autografts, with the added benefit of reduced donor-site morbidity. The QT represents an excellent graft option in anterior cruciate ligament (ACL) reconstruction, both in the primary and revision settings, among adult and pediatric populations.
