Analysis of microvascular density and collagen structure of the medial meniscotibial ligament of the knee: Immunohistochemical study with CD31 and histology with Picrosirius red.

Background: The aim of the present study was to describe the structure of the collagen matrix and the microvascularization of the medial meniscotibial ligament (MMTL), in order to contribute to the refinement of the surgical technique for repairing these structures and consequently lead to a reduction in the risk of anterior cruciate ligament re-rupture.

Methods: Twelve MMTLs were obtained from deceased organ donors. The ligaments were initially analyzed macroscopically and evaluated histologically using hematoxylin and eosin staining.

Atypical Tibial Fracture Treated with Osteosynthesis Associated with Total Knee Arthroplasty: Case Report.

Bisphosphonates are widely used in the treatment of osteoporosis but predispose the patient to the appearance of atypical fractures. The femoral subtrochanteric region is usually affected, but other bones can be as well. Atypical tibia fractures in patients with severe gonarthrosis is a therapeutic challenge.

Medial Meniscotibial Ligament of the Knee: A Step by-Step Dissection.

 Considerable attention has been paid to meniscotibial ligaments (MTLs), also known as coronary ligaments, especially after the "Save the Meniscus" initiative gained importance among knee surgeons. Technically challenging, the diagnosis and treatment of ramp lesion show the importance of MTLs. These ligaments were discovered long ago, but their contribution to knee stability has only recently been studied and still lacks information.

Anatomy of the Medial Meniscotibial Ligament of the Knee: A Systematic Review.

 To perform a systematic review of the literature on the anatomy of the medial meniscotibial ligaments (MTLs), and to present the most accepted findings, as well as the evolution of the anatomical knowledge on this structure.  An electronic search was conducted in the MEDLINE/PubMed, Google Scholar, EMBASE and Cochrane library databases with no date restrictions. The following index terms were used in the search: AND AND AND .

Outcomes of the Carlson Approach in the Treatment of Posterior Tibial Plateau Fractures.

 To describe a series of cases of tibial fractures surgically treated using the posterior approach as described by Carlson, focusing on evaluating its functional results and complication rate.  Eleven patients with tibial plateau fractures, who underwent surgical treatment using the Carlson approach from July to December 2019, were followed-up. The minimum follow-up period was defined as 6 months.

Study of the nerve endings and mechanoreceptors of the medial meniscotibial ligament of the knee: A structural and distribution analysis.

Background: The aim of the present study is to describe the morphology and distribution of the nerve endings of the meniscotibial ligament (MTL) of the knee, in order to understand the interaction between the proprioceptive system and knee mechanics.

Methods: Twenty medial MTLs were obtained from deceased organ donors. The ligaments were measured, weighed and cut.

All-Inside Technique for Ramp Lesion Repair: Arthroscopic Suture With Knee Scorpion Suture Passer.

Ramp lesions are peripheral tears of the posterior horn of the medial meniscus that involve the meniscocapsular attachments. They are commonly associated with anterior cruciate ligament injury and frequently not diagnosed. There are several suture techniques for ramp lesions.

THE IMPACT OF COVID-19 ON THE EPIDEMIOLOGICAL PROFILE OF FRACTURES.

Objective: To analyze the epidemiological transition of fractures in patients who were treated in a tertiary hospital which is reference in traumatology during the COVID-19 pandemic to assess the changes in trauma service.

Methods: This is a retrospective and descriptive analysis of data on orthopedics lesions treated at Instituto Doutor Jose Frota between December 16, 2019 and June 16, 2020 (three months before and after the first case of COVID-19 in Ceará).

Results: In total, we evaluated 913 patients, 28.

EPIDEMIOLOGY, CLASSIFICATION, AND TREATMENT OF BILATERAL FRACTURES OF THE DISTAL RADIUS.

Objective: To study epidemiology, fracture pattern, associated injuries, and treatment of individuals with bilateral distal radius fracture, in a tertiary hospital.

Methods: Retrospective cross-sectional study developed based on patients with bilateral distal radius fracture from January 2012 to November 2017. Demographic data, trauma mechanism, radiological patterns, degree of deviation, associated injuries, classification of fractures according to the Association of Osteosynthesis (AO), the Salter-Harris (SH) and Frykman scales, and type of treatment used in each case.

DOES ULNA FIXATION ALTER THE OUTCOME FOR DISTAL-THIRD FOREARM FRACTURES IN CHILDREN?

Introduction: Fractures of the distal third of the forearm are common in the pediatric population. Conservative treatment of an ipsilateral fracture of the distal ulna metaphysis is one of the risk factors for loss of reduction. Percutaneous fixation of the fracture with K-wires is recommended.

Bilateral Pseudoarthrosis of the Medial End of the Clavicles: A Rare Case Report with a Two-Year Follow-Up.

Bilateral clavicle fractures are considered rare. Most of the cases are caused by high energy traumas, such as automobile accidents. Such fracture is related to a higher frequency and severity of associated lesions.

Bilateral Avulsion Fracture of the Fibula Head of the Knee Associated with Avulsion Fracture of the Iliotibial Band: A Rare Case of Fracture Segond Associated with Arcuate Fracture.

Fibular head avulsion fractures are rare and are so-called the arcuate signal. Avulsion fracture of the iliotibial band and anterolateral ligament is known as a Segond fracture, and it is another rare entity. We describe the case of a 27-year-old woman who was hit by a car and suffered polytrauma, mainly suffering injuries to both knees.
