A comparative study of the epiligament of the medial collateral and the anterior cruciate ligament in the human knee. Immunohistochemical analysis of collagen type I and V and procollagen type III.

Ann Anat 2019 Apr 22. Epub 2019 Apr 22.

Department of Anatomy, Histology and Embryology, Medical University of Sofia, Bulgaria.

Background: Recent reports in rat models have shown that fibroblasts in the epiligament, an enveloping tissue of the ligament, are not static cells and play an important role during the early ligament healing of isolated grade III injury of the collateral ligaments of the knee. Fibroblasts produce collagen types I, III and V and infiltrate within the ligament body via the endoligament. In addition, similarities have been reported between the structure of the epiligament of the medial collateral ligament and anterior cruciate ligament of the knee in rat and in human. Read More

Knee Surgery-Arthroscopy and Sports Injuries Unit, Orthopedic Department, Mansoura University, Mansoura, Egypt.

Combined anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries are the most common type of combined ligamentous injury of the knee. The optimal treatment for these combined injuries is controversial. Combined ACL and MCL-posterior oblique ligament (POL) reconstruction avoids late anteromedial rotatory instability and chronic valgus instability of the knee and decreases the increased stress on the ACL graft.

Cells Tissues Organs 2019 Mar 15:1-17. Epub 2019 Mar 15.

Department of Anatomy, Histology and Embryology, Medical University of Sofia, Sofia, Bulgaria.

The medial collateral ligament of the knee joint is one of the most commonly injured ligaments of the knee. Recent data have shown that the thin layer of connective tissue covering the ligament, known as the epiligament, is essential for its nutrition and normal function, as well as its healing after injury. The aim of the present study was to investigate and compare the changes in the epiligament of the medial collateral ligament which occurred during operative and non-operative treatment throughout the first month after injury.

Repair and Augmentation with Internal Brace in the Multiligament Injured Knee.

Clin Sports Med 2019 Apr 19;38(2):275-283. Epub 2019 Jan 19.

The Wellington and Portland Children's Hospitals, Queen Anne Street Medical Centre, 18-22, Queen Anne Street, London W1G 8HU, UK.

The internal brace is a ligament repair bridging concept using braided ultra-high-molecular-weight polyethylene suture tape and knotless bone anchors to reinforce ligament strength to allow early mobilization during early-phase healing. This concept can be used in the management of anterior cruciate ligament, posterior cruciate ligament, anterolateral ligament, medial collateral ligament, posteromedial corner, and posterolateral corner injuries. Ligament reinforcement is a concept in which a graft is reinforced and can be used in all aspects of knee ligament reconstruction. Read More

Johns Hopkins University School of Medicine, Russell H. Morgan Department of Radiology and Radiological Science, 601 N. Caroline Street, JHOC 3142, Baltimore, MD 21287, USA. Electronic address:

The Segond fracture is a tibial avulsion injury of the insertion of the middle third of the lateral capsular ligament that is typically associated with anterior cruciate ligament and meniscal tears. The classically assigned mechanism of injury is a combination of internal rotation and varus stress. We report two cases of Segond fractures that presented with a variant pattern including osseous avulsion injuries of the medial collateral ligament at the femoral origin, anterior cruciate ligament tear, and pivot shift-type osseous contusion pattern, suggesting an alternative mechanism of injury that includes dominant valgus stress and external rotation components.

Multiligament Repair With Suture Augmentation in a Knee Dislocation With Medial-Sided Injury.

Arthrosc Tech 2018 Aug 16;7(8):e839-e843. Epub 2018 Jul 16.

Orthopaedic Trauma Service, Department of Orthopaedic Surgery, Hospital for Special Surgery, Weill Medical College of Cornell University, New York, NY, U.S.A.

Knee dislocations often result in a severe multiligament injured knee (MLIK) with complex instability. Multiligament reconstruction can successfully restore knee stability and is commonly recommended, although surgical morbidity is induced by graft harvesting and tunnel drilling, and convergence of multiple tunnels can complicate the surgery. Therefore, as an alternative, primary repair of knee ligaments is currently reconsidered. Read More

Validation of Noncontact Anterior Cruciate Ligament Tears Produced by a Mechanical Impact Simulator Against the Clinical Presentation of Injury.

Am J Sports Med 2018 Jul 4;46(9):2113-2121. Epub 2018 Jun 4.

Department of Orthopedic Surgery, Mayo Clinic, Rochester, Minnesota, USA.

Background: Anterior cruciate ligament (ACL) injuries are catastrophic events that affect athletic careers and lead to long-term degenerative knee changes. As injuries are believed to occur within the first 50 milliseconds after initial contact during a rapid deceleration task, impact simulators that rapidly deliver impulse loads to cadaveric specimens have been developed. However, no impactor has reproducibly and reliably created ACL injures in a distribution that mimics clinical observation. Read More
