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 .
There is no difference between quadriceps- and hamstring tendon autografts in primary anterior cruciate ligament reconstruction: a 2-year patient-reported outcome study
Purpose Graft choice for anterior cruciate ligament ( ACL ) reconstruction is crucial , however the optimal graft source remains a topic of controversy . The purpose of this study is to compare subjective and functional patient-reported outcomes ( PRO ) after single-bundle ACL reconstruction using quadriceps tendon ( QT ) or hamstring tendon ( HT ) autografts for single-bundle ACL reconstruction . We hypothesize that there is no difference in patient-reported functional outcomes after ACL reconstruction using either HT- or QT autograft . Methods All data were extracted from a prospect ively collected ACL registry . A total of 80 patients with at least 2-year follow-up were included in this study . A total of 40 patients with primary ACL reconstruction using a QT autograft harvested via a minimally invasive technique were matched by sex , age and pre-injury Tegner and Lysholm score to 40 patients who received HT autografts .  Subjective and functional PRO scores including Lysholm score , Tegner activity level and visual analogue scale for pain were obtained at 6 , 12 and 24 months after index surgery . Results No significant difference between the QT and the HT group was seen at any follow-up in regard to any of the PRO scores for function or pain . 24 months post-surgery the mean Tegner activity score of the HT group was significantly ( p = 0.04 ) lower compared to the pre-injury status . At final follow-up , 27 patients ( 67.5 % ) in the QT group and 32 patients ( 80.0 % ) in the HT returned to their pre-injury activity level ( n.s . ) . A total of 37 patients ( 92.5 % ) of the QT cohort and 35 patients ( 87.5 % ) of the HT cohort reported “ good ” or “ excellent ” results according to the Lysholm score ( n.s . ) . “ No pain ” or “ slight pain ” during severe exertion was reported by 33 patients ( 82.5 % ) with QT autograft and 28 patients ( 82.4 % ) with HT autograft ( n.s . ) . Conclusion There is no significant difference between PRO 2 years post-operative using either QT or HT autografts . Both QT and HT grafts show acceptable and comparable PRO scores making the QT a reliable graft alternative to HT for primary ACL reconstruction . Level of evidence III
