Abstract
BACKGROUND: Quadriceps tendon (QT) autograft represents an excellent option for anterior cruciate ligament (ACL) reconstruction (ACLR), with minimal donor site morbidity and failure rates comparable with bone-patellar tendon-bone (BPTB) autograft. This video aims to provide technical tips for ACLR using all-soft-tissue QT autograft. INDICATIONS: ACLR with QT autograft is indicated in young, active ACL-injured patients who desire a return to sport. It represents a viable option in both primary and revision ACLR, as well as in skeletally immature patients. It is particularly indicated in those who kneel frequently, such as wrestlers or laborers, due to the lower incidence of postoperative anterior knee pain. TECHNIQUE DESCRIPTION: A vertical incision is used to harvest a 10 mm × 70 mm partial thickness, all-soft-tissue QT graft. Care is taken not to violate the capsule or musculature. If necessary, graft size is modified based on preoperative magnetic resonance imaging (MRI) measurement of the notch width. The graft is then prepared with continuous loop suspensory fixation on the femoral side and draw sutures on the tibial side. The lateral femoral notch is debrided to allow for visualization of the posterior wall to enable anatomic tunnel placement. When possible, the tibial stump is preserved. The femoral tunnel is drilled via an anteromedial portal and the tibial tunnel via a tibial guide. The graft is then passed through the tibial stump into the femur. It is fixed on the tibial side with a PEEK interference screw in full extension with application of a posterior drawer. RESULTS: Outcomes following ACLR with QT autograft are excellent, with laxity and patient-reported outcomes comparable with those following ACLR with BPTB and hamstring autograft. Furthermore, QT ACLR has been shown to result in less donor site morbidity than BPTB autograft, and lower rates of failure and infection compared with hamstring autograft. CONCLUSION: ACLR with QT autograft is a good option in young, active patients in both the primary and revision settings. Advantages of QT ACLR include less donor site morbidity than BPTB, and lower rates of failure compared with hamstring autograft in young patients.
