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 .
Is quadriceps tendon a better graft choice than patellar tendon? a prospective randomized study.
PURPOSE The purpose of this r and omized controlled study was to compare knee stability , kneeling pain , harvest site pain , sensitivity loss , and subjective clinical outcome after primary anterior cruciate ligament ( ACL ) reconstruction with either bone-patellar tendon-bone ( BPTB ) or quadriceps tendon-bone ( QTB ) autografts  in a noninferiority study design . METHODS From 2005 to 2009 , a total of 51 patients were included in the present study . Inclusion criteria were isolated ACL injuries in adults . Twenty-five patients were r and omized to BPTB grafts and 26 to QTB grafts .  An independent examiner performed follow-up evaluations 1 and 2 years postoperatively . Anteroposterior knee laxity was measured with a KT-1000 arthrometer ( MEDmetric , San Diego , CA ) . Anterior knee pain was assessed clinical ly and by knee-walking ability . Knee Injury and Osteoarthritis Outcome Score ( KOOS ) and subjective International Knee Documentation Committee ( IKDC ) score were used for patient-evaluated outcome . RESULTS Anterior knee laxity was equal between the 2 groups with KT-1000 values of 1.1 ± 1.4 mm and 0.8 ± 1.7 mm st and ard deviation ( SD ) at follow-up in QTB and BPTB groups , respectively ( P = .65 ) , whereas positive pivot shift test results were seen less frequently ( 14 % compared with 38 % , respectively ; P = .03 ) . Anterior kneeling pain , evaluated by the knee walking ability test , was significantly less in the QTB group , with only 7 % of patients grading knee walking as difficult or impossible compared with 34 % in the BPTB group . At 1 and 2 years ' follow-up , there was no difference between the 2 groups in subjective patient-evaluated outcome . The IKDC score was 75 ± 13 patients and 76 ± 16 SD at 1-year follow-up in QTB and BPTB groups , respectively ( P = .78 ) . At 2 years , 12 patients were lost to follow-up , result ing in 18 in the BPTB group and 21 in the QTB group . CONCLUSIONS The use of the QTB graft results in less kneeling pain , graft site pain , and sensitivity loss than seen with BPTB grafts ; however , similar anterior knee stability and subjective outcomes are seen . The results of this study show that QTB is a viable option for ACL reconstruction . LEVEL OF EVIDENCE Level II , r and omized controlled clinical trial
