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 .
Comparison of Patellar Tendon and Hamstring Tendon Anterior Cruciate Ligament Reconstruction
Background : Numerous studies have compared patellar tendon ( PT ) and hamstring tendon ( HS ) anterior cruciate ligament ( ACL ) reconstructions in the short to midterm , but fewer long-term results have been published . Hypothesis : There will be no difference in functional outcome between ACL reconstruction performed with PT and HS grafts , but PT grafts will have more donor site morbidity . Study Design : R and omized controlled trial ; Level of evidence , 1 . Methods : Sixty-five patients undergoing ACL reconstruction were r and omized to receive either a PT graft or a 4-str and HS graft . Early results were reported at 4 , 8 , 12 , 24 , and 36 months . Forty-seven patients ( 22 of 31 PT and 25 of 34 HS ) were review ed at a mean of 15.3 years . Results : Four graft ruptures ( 1 PT , 3 HS ) and 6 contralateral ACL injuries ( 4 PT , 2 HS ) occurred in the group that was review ed . There was no statistically significant difference between the groups for any of the variables measured . There was a similar incidence of anterior knee pain and kneeling pain in both groups . The previously observed increased extension deficit in the PT group at 3 years was not present at 15 years , and there was no significant between-group difference in knee laxity . A higher proportion of patients in the PT group were participating in sport on a weekly basis ( 73 % PT , 48 % HS ; P = .05 ) . There was no difference in the degree of osteoarthritis between the groups . Conclusion : This r and omized controlled trial showed that HS and PT ACL reconstructions have comparable results at an average 15-year follow-up . Contrary to the study hypothesis , some of the graft differences seen at earlier review were not present at 15 years , and patients with PT grafts were more active in sport participation . Overall , both graft types provided good long-term subjective and objective outcomes
