Lateral extra-articular reconstruction length changes during weightbearing knee flexion and pivot shift: A simulation study.

Orthop Traumatol Surg Res 2019 Apr 17. Epub 2019 Apr 17.

Group Ramsay-générale de santé, centre orthopédique Santy, hôpital privé Jean-Mermoz, 69008 Lyon, France.

Introduction: Variations in the length of lateral extra-articular reconstruction (LER) have been widely investigated during knee flexion but there is no information about length changes during pivot shift. This study sought to assess the changes in LER tension during weightbearing knee flexion in a normal knee and in a computer-simulated pivot-shift scenario.

Hypothesis: Placing the femoral tunnel posterior and proximal to the lateral femoral epicondyle allows the LER to tighten early in the flexion range during weightbearing (squatting motion) and simulated pivot-shift. Read More

Department of Orthopaedic Surgery, Tan Tock Seng Hospital, Singapore.

We present a unique case of tibial post fracture of a posterior-stabilised total knee arthroplasty (PS-TKA) using highly crosslinked polyethylene (HXLPE) in the unafflicted limb of a patient who had poliomyelitis. The tibial post is an upright structure perpendicular to the PE insert articular surface which articulates with the cam of the femoral component to prevent excessive posterior translation of the tibia. We explore the choice of PS polyethylene (PE) inserts in patients with neuromuscular disorders (NMD). Read More

Influence of soft tissue on bone density and microarchitecture measurements by high-resolution peripheral quantitative computed tomography.

Bone 2019 Apr 15. Epub 2019 Apr 15.

Endocrine Unit, Massachusetts General Hospital, 50 Blossom Street, THR-1051 Boston, MA, USA; Harvard Medical School, 25 Shattuck St., Boston, MA, USA; Center for Advanced Orthopedic Studies, Beth Israel Deaconess Medical Center, One Overland Street, Boston, MA, USA.

High-resolution peripheral quantitative computed tomography (HR-pQCT) is a non-invasive method of measuring volumetric bone mineral density (vBMD) and microarchitecture at the distal radius and tibia. With increasing use of this technology, it is crucial to understand the potential impact of overlying soft tissue on the accuracy of HR-pQCT measures. Thus, we examined the effects of a simulated increase in adiposity (via 6- and 12-mm thick layers of overlying circumferential fat) on HR-pQCT measures of a hydroxyapatite (HA) phantom and in women (n = 20, aged 18-75 years).

Management of Pediatric Tibial Shaft Fractures.

J Am Acad Orthop Surg 2019 Apr 16. Epub 2019 Apr 16.

From the University of Texas Health Science Center at San Antonio, San Anotonio, TX.

Diaphyseal tibia fractures in the pediatric population have dynamic treatment strategies that depend on injury pattern, mechanism, patient skeletal maturity and size. Treatment strategies include closed reduction and cast immobilization, flexible nails, uniplanar or multiplanar external fixation or plate osteosynthesis. Accepted parameters for sagittal and coronal alignment vary based on age and potential for remodeling, although all fractures should have minimal rotational malalignment and less than 1 cm of shortening.

J Child Orthop 2019 Apr;13(2):120-133

Paley Orthopedic and Spine Institute, West Palm Beach, Florida, United States.

Congenital pseudarthrosis of the tibia (CPT) is likely to be a primary periosteal disease and secondary bone disease. The primary goal of treatment is to obtain union, correct the diaphyseal deformity, correct any proximal fibular migration and prevent refracture. The pathobiology demonstrates increased osteoclasis by the surrounding fibrous hamartoma and reduced osteogenesis and bone morphogenic protein production by the bone. Read More

Young individuals with chronic exercise-induced lower leg pain (ELP) who have normal compartmental muscle pressures and normal imaging occasionally suffer from a nerve entrapment syndrome. These patients have consistently undergone a variety of diagnostic tests and often futile therapies prior to arriving at the correct diagnosis. Awareness among traumatologists regarding these nerve entities is low. Read More

Establishing a common instantaneous center of rotation for the metatarso-phalangeal and metatarso-sesamoid joints: a theoretical geometric model based on specific morphometrics.

J Orthop Surg Res 2019 Apr 16;14(1):107. Epub 2019 Apr 16.

Center for Statistical Research and Methodology, U.S. Census Bureau, Washington, D.C., USA.

Background: Previous research has identified separate sagittal plane instantaneous centers of rotation for the metatarso-phalangeal and metatarso-sesamoid joints, but surprisingly, it does not appear that any have integrated the distinctive morphological characteristics of all three joints and their respective axes into a model that collectively unifies their functional motions. Since all joint motion is defined by its centers of rotation, establishing this in a complicated multi-dimensional structure such as the metatarso-phalangeal-sesamoid joint complex is fundamental to understanding its functionality and subsequent structural failures such as hallux abducto valgus and hallux rigidus.

Methods: Based on a hypothesis that it is possible to develop an instantaneous center of rotation common to all four osseous structures, specific morphometrics were selected from a sequential series of 0. Read More

Biomechanical comparison of meniscus-suture constructs for pullout repair of medial meniscus posterior root tears.

J Exp Orthop 2019 Apr 15;6(1):17. Epub 2019 Apr 15.

Sports Orthopaedic Center, Yukioka Hospital, 2-2-3 Ukita, Kita-ku, Osaka, Osaka, 530-0021, Japan.

Background: Transtibial pullout repair for posterior meniscus root tear is widely performed to restore meniscal function. However, it is sometimes technically difficult to pass the suture through the posterior medial meniscus root in narrow joint space. To address this limitation, a new suture technique using an all-inside meniscal suture device through the tibial tunnel was proposed. Read More

[Osteotomies around the Knee].

Z Orthop Unfall 2019 Apr 15;157(2):203-218. Epub 2019 Apr 15.

Osteotomies around the knee in unicompartimental osteoarthritis had an impressing revival in the past few years and have to be kept in mind as an alternative to total knee arthroplasty. The most frequent type of osteotomies around the knee is the medial open wedge high tibia osteotomy (MOWHTO). But still also closed wedge high tibia osteotomies (CWHTO) have their relevance in many cases. Read More

Predictors of Healing Ligament Size and Magnetic Resonance Signal Intensity at 6 Months After Bridge-Enhanced Anterior Cruciate Ligament Repair.

Am J Sports Med 2019 Apr 15:363546519836087. Epub 2019 Apr 15.

Investigation performed at Boston Children's Hospital, Boston, Massachusetts, USA.

Background: Primary repair of the anterior cruciate ligament (ACL) augmented with a tissue engineered scaffold to facilitate ligament healing is a technique under development for patients with ACL injuries. The size (the amount of tissue) and signal intensity (the quality of tissue) of the healing ligament as visualized on magnetic resonance imaging (MRI) have been shown to be related to its strength in large animal models.

Hypothesis: Both modifiable and nonmodifiable risk factors could influence the size and signal intensity of the repaired ligament in patients at 6 months after surgery. Read More
