The comparison of clinical efficacy of arthroscopic anterior cruciate ligament reconstruction via autologous bone-patellar tendon-bone, autologous hamstring tendon and allogeneic bone-patellar tendon-bone

Objective: To compare the clinical efficacy of anterior cruciate ligament (ACL) reconstruction via autologous bone-patellar tendon-bone (auBPB), autologous hamstring tendon (auHT) and allogeneic bone-patellar tendon-bone (alBPB) under arthroscope. Methods: One hundred and thirty four cases of patients who accepted ACL reconstruction in our hospital from December 2013 to January 2016 were randomly assigned to three groups: auBPB group (n=40), auHT group (n=59), alBPB group (n=35). The operative time, hospital days, postoperative fever time, Lysholm, Tegner and IKDC knee functional scores at the eighteenth month of follow-up, Lachman test results, pivot-shift test results and the incidence of adverse events of each group were observed and compared. Results: There was no significant difference in general conditions, injury time, stoller grade classification, Lysholm, Tegner and IKDC scores at the eighteenth month of follow-up, the results of Lachman test and pivot-shift test, postoperative average fever time, hospital days, the incidence of postoperative deep venous thrombosis and infection among three groups (all P>0.05). The operative time of alBPB group was significantly shorter than those of the other two groups (P<0.05). The anterior knee pain of auBPB group was significantly more than those of the other two groups (P=0.003 vs. auHT, P=0.029 vs. alBPB). Conclusion: All the reconstruction of ACL via auBPB, auHT and alBPB could achieve positive postoperative knee joint stability, but the incidence of postoperative anterior knee pain after reconstruction of ACL via auBPB was higher.
