Alterations in Joint Angular Velocity Following Traumatic Knee Injury in Ovine Models.

Ann Biomed Eng 2019 Jan 17. Epub 2019 Jan 17.

McCaig Institute for Bone & Joint Health, Cumming School of Medicine, University of Calgary, Calgary, AB, Canada.

Little effort has been directed towards the consequence of an injury on joint angular velocity. We hypothesized that the magnitude of knee joint angular velocity would be decreased after injury. Four injury groups were investigated in an ovine model: (1) anterior cruciate ligament (ACL) and medial collateral ligament (MCL) transection (ACL/MCL Tx) (n = 5), (2) lateral meniscectomy (Mx) (n = 5), (3) partial ACL transection (p-ACL Tx) (n = 5), and (4) partial-ACL and MCL transection (p-ACL/MCL Tx) (n = 5).

Avulsion fracture of the medial collateral ligament association with Segond fracture.

Clin Imaging 2019 Jan - Feb;53:32-34. Epub 2018 Sep 11.

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.

Concomitant injuries may not reduce the likelihood of achieving symmetrical muscle function one year after anterior cruciate ligament reconstruction: a prospective observational study based on 263 patients.

Knee Surg Sports Traumatol Arthrosc 2018 Oct 5;26(10):2966-2977. Epub 2018 Feb 5.

Department of Orthopaedics, Institute of Clinical Sciences, The Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.

Purpose: A better understanding of patient characteristics and the way common concomitant injuries affect the recovery of muscle function after surgery should help providers to treat patients with anterior cruciate ligament (ACL) injuries. The aim of this study was to determine whether patient characteristics, concomitant injuries and graft choice at ACL reconstruction were associated with symmetrical knee muscle function at one year. The hypothesis was that the presence of concomitant injuries would negatively influence the opportunity to achieve symmetrical knee function at the one-year follow-up. Read More
