Outcomes of quadriceps tendon autograft versus bone-patellar tendon-bone autograft for anterior cruciate ligament reconstruction:a Meta-analysis / 中国骨伤

ABSTRACT

OBJECTIVE@#To evaluate clinical effect of quadriceps tendon autograft and bone-patellar tendon-bone autograft on anterior cruciate ligament reconstruction by Meta-analysis.@*METHODS@#From the time of building databases to May 2019, literatures on case control study on quadriceps tendon and bone-patellar tendon-bone autograft on anterior cruciate ligament reconstruction were searched form PubMed, EMbase, the Cochrane library, Wanfang and CNKI database. Literature screening, quality evaluation and data extraction were carried out according to include and exclude standard. Difference of forward displacement between the affected and health knee, Lachman test, axial shift test, Lysholm score, international knee documentation committee (IKDC) objective grade, anterior knee joint pain and transplant failure rate were analyzed by Meta analysis.@*RESULTS@#Totally 6 literatures were included, including 915 patients with anterior cruciate ligament reconstruction, 495 patients with quadriceps tendon autograft and 420 patients with bone patellar tendon bone autograft. There were no statistical differences in anterior displacement of tibia was less than 3 mm[=1.53, 95%CI(0.68, 3.44), =0.31], 3 to 5 mm [=0.64, 95%CI(0.31, 1.35), =0.24], greater than 5 mm[=1.18, 95%CI(0.33, 4.22), =0.80], negative rate of Lachman test[=0.88, 95%CI(0.38, 2.02), =0.76], negative rate of axial shift test[=0.63, 95%CI(0.24, 1.68), =0.36] between two groups. There were no differences in Lyshlom score[=-0.56, 95%CI(-2.00, 0.89), =0.45], IKDC objective grade A and B[=0.87, 95%CI (0.47, 1.60), =0.66], and transplant failure rate [=0.76, 95%CI (0.28, 2.02), = 0.58]. In reducing anterior knee pain, quadriceps tendon autograft was better than that of bone patellar tendon bone autograft [=0.16, 95%CI (0.09, 0.29), <0.000 01].@*CONCLUSION@#Quadriceps tendon autograft and bone patellar tendon bone autograft on anterior cruciate ligament reconstruction has equal clinical and functional outcomes, transplant failure rate, quadriceps tendon autograft could reduce anterior knee pain. For patients with anterior cruciate ligament reconstruction, quadriceps tendon autograft could be seen as suitable alternative bone graft substitutes for anterior cruciate ligament reconstruction.
