Arthroscopic reduction and internal fixation of avulsion fracture of anterior cruciate ligament from tibial eminence with sutures by four tibial tunnels

OBJECTIVES: To investigate the therapeutic efficacy of arthroscopic reduction and internal fixation of avulsion fracture of anterior cruciate ligament (ACL) from tibial eminence with sutures by four tibial tunnels. METHODS: Twenty five cases of avulsion fracture of ACL from tibial eminence were treated by arthroscopic reduction and internal fixation with sutures by four tibial tunnels tibial from March 2012 to March 2015.The average follow-up period was 18 months, ranging from 12 to 24 months. The follow-up assessment included anterior drawer test，Lachman test，pivot shift，Lysholm knee score and the radiological evaluation. RESULTS: All cases successfully achieved reduction and bone union.The knee function was good.The results of anterior drawer test，Lachman test and pivot shift were negative．The preoperative and final follow-up Lysholm knee scores were ( 45.2±6.5) and ( 95.2±4.7) points respectively with statistically significant differenece (t =21. 4，P<0.05). CONCLUSION: The arthroscopic reduction and internal fixation of avulsion fracture of ACL from tibial eminence with sutures by fou rtibial tunnels is minimally invasive and convenient with satisfactory reduction and fixation,which can benefit the posoperative rehabilitation．It can avoid reoperation and achieve excellent results．
