【摘要】Background Recently,increasing number of literature has identified the posterior tibial slope (PTS) as one of the risk factors of primary anterior cruciate ligament (ACL) injury.However,few studies conceming the association between failure of ACL reconstruction (ACLR) and PTS have been published.The objective of this study was to explore the association between the failure of ACLR and PTS at a minimum of two years follow-up.Methods Two hundred and thirty eight eligible patients from June 2009 to October 2010 were identified from our database.A total of 20 failure cases of ACLR and 20 randomly selected controls were included in this retrospective study.The demographic data and the results of manual maximum side-to-side difference with KT-1000 arthrometer at 30° of knee flexion and pivot-shift test before the ACLR and at the final follow-up were collected.The medial and lateral PTSs were measured using the magnetic resonance imaging (MRI) scan,based on Hudek's measurement.A comparison of PTS between the two groups was performed.Results The overall failure rate of the present
