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 .
Anterior cruciate ligament reconstruction: bone-patellar tendon-bone compared with double semitendinosus and gracilis tendon grafts. A prospective, randomized clinical trial.
BACKGROUND The choice of graft for anterior cruciate ligament reconstruction is a matter of debate , with patellar and hamstring tendons being the two most popular autologous graft options . The objective of this study was to determine in a prospect i ve , r and omized clinical trial whether two grafts ( bone-patellar tendon-bone or doubled hamstring tendons ) fixed with modern devices affect the two-year minimum clinical and radiographic outcomes of anterior cruciate ligament reconstruction . METHODS One hundred and twenty patients with a chronic unilateral rupture of the anterior cruciate ligament underwent arthroscopically assisted reconstruction with use of either autologous bone-patellar tendon-bone or doubled hamstring tendon grafts  , in a strictly alternating manner . Both groups were comparable with regard to demographic data , preoperative activity level , mechanism of injury , interval between the injury and the operation , and the amount of knee laxity present preoperatively . The same well-proven surgical technique and aggressive controlled rehabilitation was used . An independent observer , who was blinded with regard to the involved leg and the type of graft , performed the outcome assessment with use of a visual analog scale , the new International Knee Documentation Committee form , the Knee Injury and Osteoarthritis Outcome Score , the Functional Knee Score for Anterior Knee Pain , and an arthrometric and an isokinetic dynamometric evaluation . Radiographs were also made . RESULTS At the two-year follow-up evaluation , no differences were found in terms of the visual analog score , the Knee Injury and Osteoarthritis Outcome Score , the new International Knee Documentation Committee subjective and objective evaluation scores , the KT-1000 side-to-side laxity measurements , the Functional Knee Score for Anterior Knee Pain , muscle strength recovery , or return to sports activities . In the bone-patellar tendon-bone group , we found a higher prevalence of postoperative kneeling discomfort ( p < 0.01 ) and an increased area of decreased skin sensitivity ( p < 0.001 ) . In the hamstring tendon group , we recorded a higher prevalence of femoral tunnel widening ( p < 0.01 ) . In this group , a correlation was also found between medial meniscectomy and an increased prevalence of pivot-shift glide ( p = 0.035 ) . CONCLUSIONS We believe that , with use of accurate and proven surgical and rehabilitation techniques , both grafts are an equivalent option for anterior cruciate ligament reconstruction
