The Clinical Outcome of Simultaneous Lateral Closed- Wedge Distal Femoral Osteotomy and Anterior Cruciate Ligament Reconstruction in the ACL-deficient Knees with Symptomatic Femoral Varus Deformity
Background: Nowadays combined high tibial osteotomy and ACL reconstruction is accepted as a safe and effectivesurgery for patients with symptomatic varus osteoarthritis and anterior knee instability; however, the source of varusdeformity is sometimes the femoral bone. No studies have reported concomitant ACL reconstruction and distal femoralosteotomy in ACL-deficient knees wit...
متن کاملA Preliminary In Vivo Assessment of Anterior Cruciate Ligament-Deficient Knee Kinematics With the KneeM Device: A New Method to Assess Rotatory Laxity Using Open MRI.
BACKGROUND Methods of objectively measuring rotational knee laxity are either experimental or difficult to use in daily practice. A new method has been developed to quantitatively assess rotatory laxity using an open MRI system and new tool, the KneeM device. PURPOSE/HYPOTHESIS To perform a preliminary evaluation of a novel knee rotation measurement device to assess knee kinematics during fle...
متن کاملAssessment of anterolataral rotatory instability of the ACL-deficient knee using an open MRI system
Introduction: Rupture of anterior cruciate ligament (ACL) causes anterolateral rotatory instability (ALRI), which often results in an unstable knee with a symptom of “giving-way”. The clinical success of the surgical treatment for ACL-deficient knee depends on the improvement of ALRI. However, in the clinical evaluation of the ACL-deficient knee, ALRI is assessed by manual tests such as the piv...
متن کاملThe impact of bone morphology on the outcome of the pivot shift test: a cohort study
BACKGROUND The presence of a positive pivot shift after surgical repair of the ACL is considered an important indicator of a failed reconstruction. The ability to predict the result of a pivot shift test after an ACL reconstruction using variables that can be measured prior to surgery could provide an indication of which patients may be at-risk of a poor surgical outcome.The purpose of this stu...
متن کاملLateral Meniscus Posterior Root and Meniscofemoral Ligaments as Stabilizing Structures in the ACL-Deficient Knee: A Biomechanical Study
BACKGROUND The biomechanical effects of lateral meniscal posterior root tears with and without meniscofemoral ligament (MFL) tears in anterior cruciate ligament (ACL)-deficient knees have not been studied in detail. PURPOSE To determine the biomechanical effects of the lateral meniscus (LM) posterior root tear in ACL-intact and ACL-deficient knees. In addition, the biomechanical effects of di...
