Outcomes for primary anterior cruciate reconstruction with the quadriceps autograft: a systematic review

To determine the suitability of the quadriceps autograft in primary anterior cruciate ligament (ACL) reconstruction. A systematic review was undertaken to identify all clinical studies reporting on the use of the quadriceps tendon autograft in ACL reconstructions. Studies that reported on clinical and functional outcomes, morbidity and complications were selected. Seventeen articles met our inclusion criteria with a total of 1,580 reconstructions studied. This included four comparative studies which compared the quadriceps tendon to either hamstring or patella tendon autografts. The quadriceps tendon autograft had clinical (Lachman, Pivot-shift testing) and functional outcomes (Lysholm and IKDC scores) similar to those reported for the patella tendon and hamstring grafts in the literature. Comparative studies also reported no significant difference between the grafts for any outcome measure. The quadriceps tendon autograft is a promising alternative for primary ACL reconstructions with good outcomes and minimal donor site morbidity. Further studies are required, however, to determine whether the quadriceps graft is as good as or better than other autografts. IV.
