BACKGROUND The orthopaedic literature contains relatively little quantitative information regarding the anatomy of the posterior aspect of the knee. The purpose of the present study was to provide a detailed description of, and to propose a standard nomenclature for, the anatomy of the posterior aspect of the knee. METHODS Detailed dissection of twenty nonpaired, fresh-frozen knees was perfor...

Background: Evaluating concomitant injury in patients with anterior cruciate ligament (ACL) rupture is important for predicting long-term results. Meniscofemoral (MFL) has been observed arthroscopic evaluation ruptured ACL. Objectives: The objective of this study was to investigate the meniscofemoral ligaments ruptures via magnetic resonance imaging (MRI). Methods: A total 200 (with ACL, n = 10...

PURPOSE To retrospectively determine the prevalence of posterior lateral meniscus root tears (LMRTs), as depicted on magnetic resonance (MR) images, in patients with an anterior cruciate ligament (ACL) tear and to investigate the association of LMRTs with lateral meniscus extrusion and other ligament injuries. MATERIALS AND METHODS Institutional review board approval was obtained; informed co...

BACKGROUND Lateral ankle sprains are common sports injuries that may require surgery for chronic lateral ankle instability. Anatomic repair or reconstruction is desired, yet there is a scarcity of quantitative information regarding the origins and insertions of the lateral ligaments related to surgically pertinent osseous landmarks. METHODS Fourteen ankle specimens were dissected to isolate t...

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...

The meniscofemoral ligaments (MFL) of the knee have both functional and clinical importance, but have been poorly described. We examined 42 human cadaver knees: there was at least one MFL in every joint and both ligaments were present in 27. The anterior MFL was present in the knees in all 18 males and in 17 of the 24 females. The posterior MFL was present in 16 males and 22 females. Measuremen...

To reveal the detailed morphological features of the fibular collateral (fibular) ligament, popliteus tendon, popliteofibular ligament and the synovial components regarding to achieve data for surgical and biomechanical utilization. Knees of 10 formalin-fixed male cadavers were dissected bilaterally. Bursae around the lateral collateral ligament and the relation of popliteus tendon with lateral...

BACKGROUND While the anatomy of the medial part of the knee has been described qualitatively, quantitative descriptions of the attachment sites of the main medial knee structures have not been reported. The purpose of the present study was to verify the qualitative anatomy of medial knee structures and to perform a quantitative evaluation of their anatomic attachment sites as well as their rela...

Posterolateral instability (PLI) is common with posterior cruciate ligament tears and is less common with anterior cruciate ligament tears, and isolated PLI is rare. There are varying degrees of PLI with respect to pathologic external tibial rotation, and varus laxity. Surgical treatment of PLI must address all components of the PLI (popliteus tendon, popliteofibular ligament, lateral collatera...
