Objective: To asses the validity of three physical diagnostic tests for the demonstration of rupture of the anterior cruciate ligament (ACL): the anterior drawer test, the Lachman test, and the pivot shift test. Design: Meta-analysis of diagnostic studies. Data sources: From computerised searches of Medline (1966–2004) and Embase (1980–2004), publications were selected that were written in Engl...

STUDY DESIGN Meta-analysis. OBJECTIVES To define the accuracy of clinical tests for assessing anterior cruciate ligament (ACL) ruptures. BACKGROUND The cruciate ligaments, and especially the ACL, are among the most commonly injured structures of the knee. Given the increasing injury prevalence, there is undoubtedly a growing need for clinical decision making of health care providers. We rev...

PURPOSE The purpose of this study was to compare clinical outcomes after single-bundle anterior cruciate ligament (ACL) reconstruction with a free Achilles tendon allograft using either a transtibial or an anteromedial portal technique and then to quantify the difference in femoral tunnel position between these 2 approaches. This assessment was to be performed with a new method using convention...

BACKGROUND Antero-medial portal (AMP) and trans-tibial (TT) techniques are the most widely used methods for drilling femoral tunnel in ACL reconstructions; yet, debate continues about the preferred method. This study seeks to compare these 2 techniques in patients with ACL tears. MATERIAL/METHODS In this comparative study, all cases of isolated ACL reconstruction using 4-strand hamstring tend...

BACKGROUND Tear of the anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. Reconstruction of this ligament is often required to restore functional stability of the knee. Outcome of ACL reconstruction is significantly affected by how the graft is fixed to the bone. This study is to determine if there is a different clinical outcome after cortical versus cortical-cancello...

We have measured anterior and posterior displacement in 563 normal knees and 487 knees with chronic deficiency of the anterior cruciate ligament (ACL). We performed stress radiography using a simple apparatus which maintained the knee at 20 degrees of flexion while a 9 kg load was applied. There was no significant difference in posterior translation dependent on the condition of the ACL. Measur...
