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 .
Patellar tendon or semitendinosus tendon autografts for anterior cruciate ligament reconstruction: a prospective, randomized study with a 7-Year follow-up.
BACKGROUND The aim of the study was to compare the results after arthroscopic anterior cruciate ligament ( ACL ) reconstruction  using central -third bone-patellar tendon-bone ( BTB ) autografts and triple/quadruple semitendinosus ( ST ) autografts . HYPOTHESIS In the long-term , ACL reconstruction using BTB autografts will render more donor-site problems than ST autografts . STUDY DESIGN R and omized controlled trial ; Level of evidence , 1 . METHODS A r and omized series of 71 patients ( 22 women and 49 men ) with a unilateral ACL rupture who underwent reconstructive surgery were included in the study . The BTB graft was used in 34 patients ( BTB group ) and the ST-tendon graft was used in 37 patients ( ST group ) . The patients were examined a median of 86 months ( range , 68 to 114 months ) after the reconstruction . RESULTS Sixty-eight of 71 patients ( 96 % ) were examined at follow-up . The clinical assessment s at follow-up revealed no significant differences between the BTB group and the ST group in terms of the Lysholm score , Tegner activity level , International Knee Documentation Committee evaluation system , 1-legged hop test , KT-1000 arthrometer laxity measurements , manual Lachman test , and range of motion . A significant improvement was seen in both groups compared with the preoperative values in terms of most clinical assessment s. Donor-site morbidity in the form of knee-walking ability , kneeling ability , and area of disturbed anterior knee sensitivity revealed no significant differences between the groups . CONCLUSION Seven years after ACL reconstruction , the subjective and objective outcomes were similar after using the central -third BTB autograft and triple/quadruple ST autograft . Furthermore , no difference in terms of donor-site morbidity was found between the 2 groups
