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 Versus Hamstring Tendon Autografts for Anterior Cruciate Ligament Reconstruction
Background Controversy remains over the most appropriate graft for anterior cruciate ligament reconstruction . Hypothesis There is no significant difference in outcomes after 4-str and hamstring and patellar tendon autograft anterior cruciate ligament reconstructions using similar fixation techniques . Study Design R and omized controlled trial ; Level of evidence , 1 . Methods Between August 2000 and May 2003 , 64 Keller Army Hospital patients with complete anterior cruciate ligament tears were r and omized to hamstring ( n = 32 ) or patellar tendon ( n = 32 ) autograft anterior cruciate ligament reconstruction .  Operative graft fixation and rehabilitative techniques were the same for both groups . Follow-up assessment s included the Single Assessment Numeric Evaluation score , Lysholm score , International Knee Documentation Committee score , and Knee Injury and Osteoarthritis Outcome Score . Postoperative radiographs were analyzed for tunnel location and orientation . Results Eleven women and 53 men were r and omized . Eighty-three percent of the patients ( 53 of 64 ) had follow-up of greater than 2 years , or to the point of graft rupture or removal ( average follow-up , 36 months ) . Four hamstring grafts ( 12.5 % ) and three patellar tendon grafts ( 9.4 % ) ( P = .71 ) ruptured . One deep infection in a hamstring graft patient necessitated graft removal . Forty-five of the 56 patients with intact grafts had greater than 2-year follow-up . Patients with patellar tendon grafts had greater Tegner activity scores ( P = .04 ) . Single Assessment Numeric Evaluation scores were 88.5 ( 95 % confidence interval : 83.1 , 93.8 ) and 90.1 ( 95 % confidence interval : 85.2 , 96.1 ) for the hamstring and patellar tendon groups , respectively ( P = .53 ) . Lysholm scores were 90.3 ( 95 % confidence interval : 84.4 , 96.1 ) and 90.4 ( 95 % confidence interval : 84.5 , 96.3 ) for the hamstring and patellar tendon groups , respectively ( P = .97 ) . There were no significant differences in knee laxity , kneeling pain , isokinetic peak torque , International Knee Documentation Committee score , or Knee Injury and Osteoarthritis Outcome Scores . Postoperative graft rupture correlated with more horizontal tibial tunnel orientation . Conclusion Hamstring and patellar tendon autografts provide similar objective , subjective , and functional outcomes when assessed at least 2 years after anterior cruciate ligament reconstruction
