BACKGROUND: Remnant tissue preservation may be important in improving graft healing after anterior cruciate ligament (ACL) reconstruction, but it has yet to be established whether remnant tissue preservation improves the control of pivot-shift laxity. HYPOTHESIS: The amount of ACL graft coverage with preserved remnant tissue improves the control of pivot-shift laxity, as qualitatively determined with an electromagnetic device. STUDY DESIGN: Cohort study; Level of evidence, 3...

BACKGROUND: Injury to the anterolateral ligament (ALL) has been reported to contribute to high-grade anterolateral laxity after anterior cruciate ligament (ACL) injury. Failure to address ALL injury has been suggested as a cause of persistent rotational laxity after ACL reconstruction. Lateral meniscus posterior root (LMPR) tears have also been shown to cause increased internal rotation of the knee. QUESTIONS/PURPOSES: The purpose of this study was to determine the functional relationship between the ALL and LMPR in the control of internal rotation of the ACL-deficient knee...

OBJECTIVES: There are not many chances to arthroscopically reassess how graft tunnel malpositions in primary anterior cruciate ligament reconstruction (ACLR) associate with intra-articular degeneration in revision ACLR. This study was aimed to evaluate whether radiographic tunnel position in primary ACLR affect cartilaginous changes and bucket-handle meniscus tears in revision ACLR. METHODS: Thirty-five patients who underwent revision ACLR were recruited; their primary surgeries were single-bundle reconstructions...

INTRODUCTION: The cruciate ligaments are essential for the antero-posterior stability of the knee joint. In Anterior Cruciate Ligament (ACL) rupture, though reconstructive surgery is a widely accepted and proven procedure, there is still an unacceptably high re-injury rate. The fact that the rotational instability persists even after the surgical reconstruction of ACL injury has evoked a new interest in the study of the soft tissue structures on the anterolateral aspect of the knee joint...

Isolated posterior cruciate ligament (PCL) tears are much less frequent than anterior cruciate ligament (ACL) tears.Abrupt posterior tibial translation (such as dashboard impact), falls in hyperflexion and direct hyperextension trauma are the most frequent mechanisms of production.The anterolateral bundle represents two-thirds of PCL mass and is reconstructed in single-bundle techniques.The PCL has an intrinsic capability for healing. This is the reason why, nowadays, the majority of isolated PCL tears are managed non-operatively, with rehabilitation and bracing...

BACKGROUND: The Segond fracture was classically described as an avulsion fracture of the anterolateral capsule of the knee. Recently, some authors have attributed its pathogenesis to the "anterolateral ligament" (ALL). Biomechanical studies that have attempted to reproduce this fracture in vitro have reported conflicting findings. PURPOSE: To determine the anatomic characteristics of the Segond fracture on plain radiographs and magnetic resonance imaging (MRI), to compare this location with the location of the ALL described in prior radiographic and anatomic publications, and to determine the fracture's attachments to the soft tissue anterolateral structures of the knee...

BACKGROUND: Several studies have recently shown better restoration of normal knee kinematics and improvement of rotator knee stability after reconstruction with higher femoral tunnel obliquity. The aim of this study is to evaluate tunnel obliquity, length, and posterior wall blowout in single-bundle anterior cruciate ligament (ACL) reconstruction, comparing the transtibial (TT) technique and the out-in (OI) technique. MATERIALS AND METHODS: Forty consecutive patients operated on for ACL reconstruction with hamstrings were randomly divided into two groups: group A underwent a TT technique, while group B underwent an OI technique...

Calcific periarthritis in the distal femur is a rare condition. Forty two year old Asian male visited to the outpatient clinic of orthopedic department with acute excruciating knee pain. The arthroscopic posterior cruciate ligament (PCL) reconstruction was performed 20 years ago with the bonepatellar tendon-bone (BPTB) autograft combined with Trevira (polyethylene terephthalate) artificial ligament. Severe tenderness was noted incidentally over the medial epicondyle area of the distal femur which the cancellous screw was inserted for PCL reconstruction, without any preceding trauma history or medial joint line tenderness due to degenerative change...

Musculoskeletal injuries in pediatric patients are on the rise, including significant increases in anterior cruciate ligament (ACL) injuries. Previous studies have found major anatomical changes during skeletal growth in the soft tissues of the knee. Specifically, the ACL and the posterior cruciate ligament (PCL) change in their relative orientation to the tibial plateau throughout growth. In order to develop age-specific treatments for ACL injuries, the purpose of this study was to characterize orientation changes in the cruciate ligaments of the Yorkshire pig, a common pre-clinical model, during skeletal growth in order to verify the applicability of this model for pediatric musculoskeletal studies...

Multiple ligaments are involved in avulsion injuries of the knee joint, including both anterior and posterior cruciate ligaments; however, avulsion injury of the posterior cruciate ligament is less frequently encountered than the anterior counterpart. Furthermore, avulsion of the femoral side of the posterior cruciate ligament is far less common than the tibial one.Femoral attachment avulsion fracture of the posterior cruciate ligaments has been reported in literature in adolescents, rarely in adulthood, and never before in elderly patients, showing an inverse relationship with advancement in patient age...

PURPOSE: Recently, ultra-congruent (UC) inserts have shown successful outcomes following total knee arthroplasty (TKA). It was hypothesized that patients in the UC group would not show significantly different in vivo stability or functional outcomes from those in the cruciate-retaining (CR) group. METHODS: The prospective study enrolled patients who had been treated with either CR or UC TKAs (38 cases in each group), after a minimum 3-year follow-up. The same surgical technique was used with the same femoral components in both groups except for the polyethylene inserts (CR or UC)...

The role of the sub-bundles in the anterior cruciate ligament (ACL) has been defined, such that the anterior-medial bundle directly resists anterior tibial translation while the posterior lateral bundle is involved in rotational stability. With regards to this biomechanical function, much of the previous work on bundle-specific morphology has been carried out on the macroscale, with much less attention given to the micro-to-ultrastructural scalar levels. This is especially true of the enthesis and its microstructure, a biomechanically significant region that has been largely neglected in the published literature dealing with ACL sub-bundle anatomy...
