background: the knee joint is prone to injury because of its complexity and weight-bearing function. anterior cruciate ligament (acl) ruptures happen in young and physically active population and can result in instability, meniscal tears, and articular cartilage damage. the aim of this study is to evaluate the accuracy of lachman and anterior drawer test in acl injury in compare with arthroscop...

The aim of the current study was to evaluate the sensitivity of the lever sign test and the widely used basic tests of the Lachman, anterior drawer and pivot shift tests, both under anaesthesia and without anaesthesia, according to the gold standard diagnostic arthroscopic results in patients undergoing anterior cruciate ligament reconstruction. The study included 117 patients, diagnosed with A...

A prospective study was undertaken to compare the accuracy of the Lachman test, anterior drawer test and jerk test with the KT1000 knee arthrometer in patients with proven anterior cruciate ligament deficiency. The Lachman and anterior drawer tests were found to be the most accurate indicators of anterior cruciate ligament deficiency. The KT1000 knee arthrometer was found to be totally inaccura...

BACKGROUND TKA with retention of the anterior cruciate ligament (ACL) may improve kinematics and function. However, conflicting reports exist concerning the prevalence of intact ACLs at the time of TKA. QUESTIONS/PURPOSES Therefore, we asked: (1) what was the ACL status at TKA; (2) what was the sensitivity and specificity of the Lachman test; (3) did MRI ACL integrity correlate with intraoper...

The purpose of this prospective study was to quantify and compare the amount of anterior tibial translation (ATT) occurring in ACL-reconstructed knees during both a static passive Lachman test and an isokinetic knee extension exercise, pre- and postoperatively. Stress-radiography combined with an electrogoniometer system was applied to 49 knees before and after ACL reconstruction. The Lysholm s...

PURPOSE To evaluate dynamic three-dimensional (3D) kinematic properties of the anterior cruciate ligament (ACL)-insufficient knees and healthy contralateral knees in awake patients during the Lachman test using biplane fluoroscopy. MATERIALS AND METHODS Ten patients with unilateral ACL-insufficient knees and healthy contralateral knees were enrolled in this study. Each patient underwent the L...

BACKGROUND The latest version of the navigation system for anterior cruciate ligament (ACL) reconstruction has the supplementary ability to assess knee stability before and after ACL reconstruction. In this study, we compared navigation data between clinical grades in ACL-deficient knees and also analyzed correlation between clinical grading and navigation data. METHODS 150 ACL deficient knee...

strate loss of integrity of the anterior cruciate ligament. These include the anterior drawer test, the Lachman test, the jerk test and the pivot shift test. Their usefulness in the acute case is often limited because of pain and swelling. The test which we describe is painless, noninvasive and accurate. Pathomechanics. The concept of the pivot shift, although attributed to Losee and first publ...

BACKGROUND The Lachman and pivot-shift tests have been widely used for detecting anterior cruciate ligament (ACL) deficiency. However, it still remains unclear whether these manual tests can be quantified accurately while patients are awake. PURPOSE To assess the differences in knee kinematics of awake and anesthetized patients. STUDY DESIGN Case series; Level of evidence, 4. METHODS A to...

Introduction: Anterior cruciate ligament (ACL) deficiency causes an increase in anterior tibial translation. To assess the amount of the anterior-posterior tibial translation, KT-arthorometer has been widely used. However it has been suggested by some reports that the practical reliability of the KT-1000 arthrometer measurement is doubted due to the interand intra-examiner errors. The Lachman t...
