The QT autograft detected comparable rate of Lachman test > 3 mm , Pivot shift test > 3 m and instrumental laxity > 3 mm .
The QT autograft showed a lower rate of autograft failure above all .
The QT autograft detected the reduced rate of AKP than the PT .
Quadriceps tendon autograft may represent a feasible option for primary ACL reconstruction .
The purpose of the current study was to clarify the role of the quadriceps tendon ( QT ) autograft for primary ACL reconstruction .
Thus , a Bayesian network meta- analysis comparing patients undergoing a primary ACL reconstruction with QT versus patellar tendon ( PT ) and hamstring tendon ( HT ) autografts  was conducted .
Strength recovery after anterior cruciate ligament reconstruction with quadriceps tendon versus hamstring tendon autografts in soccer players: A randomized controlled trial.
BACKGROUND The comparison between HT and QT grafts in strength recovery and function  after an ACLR is scarce in the literature . METHODS A total of 56 participants were enrolled in this r and omized controlled trial and placed into two groups : HT or QT .  The hamstring/quadriceps ( H/Q ) ratio was the primary end-point measured with a Genu-3 dynamometer . Peak torque , functional assessment ( Lysholm knee scoring scale and Cincinnati Knee Rating System ) , and anteroposterior laxity ( KT-2000 ™ arthrometer ) were also assessed . An intention-to-treat analysis was performed . RESULTS The results of the H/Q ratio analysis of the participants over time revealed significant differences at 60 , 180 , and 300 ° /s at three , six , and 12months of follow-up ( 60 ° /s : F=5.3 , p=0.005 ; 180 ° /s : F=5.5 , p=0.004 ; 300 ° /s : F=5.1 , p=0.005 ) . Furthermore , they revealed significant differences at 60 ° /s , 180 ° /s , and 300 ° /s in the participants over time for peak torque in the extensor muscle strength at three and six months of follow-up , with higher values in the hamstring tendon group but not at 12months of follow-up . There were no significant differences in functional endpoints or arthrometer assessment s at 24months of follow-up . CONCLUSION An ACLR with a QT graft showed similar functional results with a better isokinetic H/Q ratio compared to an ACLR with the HT at 12months of follow-up in soccer players . This higher H/Q ratio observed with the QT could be an advantage of this graft over the HT for an ACLR
