Quadriceps Tendon-Bone Full-Thickness Autograft: Reproducible and Easy Harvesting Technique Using Simple Surgical Tools.

ABSTRACT: Autogenous quadriceps tendon-bone graft is a great choice for knee reconstruction procedures, including primary and revision reconstructions of both anterior cruciate ligament (ACL) and posterior cruciate ligament. In primary ACL reconstruction, one of the most frequently performed procedures in orthopaedic surgery, it is gaining more and more popularity owing to improved or similar biomechanical, anatomic, and histological properties than bone-patellar tendon-bone graft. The clinical outcomes of quadriceps tendon-bone graft in ACL reconstruction are similar to bone-patellar tendon-bone graft, however, lowering the inconvenience associated with donor-site morbidity and making it possible to adjust graft length and diameter. This Technical Note describes a surgical technique for harvesting a full-thickness quadriceps tendon graft with a bone block using simple surgical tools.

Project description:BackgroundDespite quadriceps weakness in individuals after quadriceps tendon anterior cruciate ligament reconstruction (QT-ACLR), and its association with knee joint mechanics, no studies have addressed gait mechanics in both partial-thickness (PT-Q) and full-thickness (FT-Q) options for QT-ACLR.ObjectiveTo assess gait mechanics across a QT-ACLR cohort. We hypothesized that QT-ACLR would show changes in knee joint mechanics compared to control participants (CON) and nonoperated limbs. Additionally, we hypothesized that FT-Q operated limbs would show greater changes compared to PT-Q and CON.DesignRetrospective cohort study.SettingUniversity-affiliated sports medicine institute.ParticipantsSixteen patients who underwent QT-ACLR (7 FT-Q: Age (years) = 28.6 ± 7.3, post-op (months) = 23.5 ± 10.7, 9 PT-Q: Age = 25.2 ± 4.3, post-op = 24.4 ± 11.7) were recruited and compared to 11 CON (age = 23.4 ± 4.8).InterventionParticipants underwent gait testing with force plate integrated motion capture.Main outcome measuresMixed repeated-measures analyses of covariance, adjusted for gait speed, were used to determine significant main effects or interactions in peak knee flexion angle, sagittal knee range of motion, peak internal knee extension moment (KEM), and peak internal knee flexion moment.ResultsWhen measured an average of 2 years after surgery, no main effect for limb or limb by depth interaction were detected. A significant effect by group was observed for peak KEM (p = .03, η2 = .27) and peak knee flexion angle (p = .04, η2 = .24) in the loading response phase. FT-Q (p = .02) and PT-Q (p = .03) showed lower KEM compared to the CON group in both limbs. The FT-Q group showed lower peak knee flexion angle compared to the CON group (p = .01).ConclusionsKnee joint symmetry may be recovered 2 years following QT-ACLR, but lower KEM compared to CON for both graft options and lower peak knee flexion angle than CON for the FT-Q group may indicate a need for further investigation in QT-ACLR.
