Ipsilateral Quadriceps Tendon-Bone ACL Revision Reconstruction to Address Failed Primary Bone-Patellar Tendon-Bone ACL Reconstruction with Persistent Patellar Bone Defect

Bone -patellar tendon -bone (BPTB) autograft is a popular graft choice for anterior cruciate ligament recon-struction (ACLR) in active young adults. In case of BPTB ACLR failure, the 3 most popular autograft choices for a revision surgery include contralateral BPTB, contralateral or ipsilateral hamstrings autograft, and contralateral or ipsilateral quadriceps tendon autograft. Quadriceps tendon autograft has been gaining increasing popularity in recent years in this respect, but using quadriceps tendon -bone autograft in the setup of a previous use of ipsilateral BPTB autograft deserves special technical considerations, with emphasis on preserving patellar bone integrity. We describe a technique for per-forming revision ACLR after failed primary BPTB ACLR by using ipsilateral quadriceps tendon -bone autograft in the setup of persistent distal patellar bone defect. Using this autograft benefits the advantages of highly resilient graft tissue in addition to fast bone-to-bone healing on the femoral side, and it can be an excellent choice in revision reconstruction for surgeons who prefer tendon-bone autograft for highly active young adults and specifically when the patients underwent bilateral primary autologous BPTB ACLRs.
