Ochronotic Arthropathy and Alkaptonuria (Ochronosis): Case Report.

Alkaptonuria (AKU) is a rare genetic condition resulting from a deficiency in the homogentisic acid oxidase enzyme, which is produced by the liver and kidneys, that interferes with the metabolism of the amino acids phenylalanine and tyrosine. Although it may not cause symptoms, AKU can lead to ochronosis, the abnormal accumulation in body tissues of a pigment called alkapton. Over time, this pigment accumulation in the joints may result in secondary osteoarthritis known as ochronotic arthropathy, the most debilitating form of the disease.

Analysis of the Biomechanical Behavior of an Animal Model of Triple Hamstring Graft Configuration for Combined ACL and ALL Reconstruction with a Single Femoral Tunnel and a Single Strand for ALL Reconstruction.

 To describe and biomechanically test a configuration, in an animal model that simulates the triple hamstring graft for combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction, with a single femoral tunnel and a single strand for ALL reconstruction.  Deep flexor porcine tendons were used as the graft and fixed with titanium interference screws in a polyurethane block. The samples were divided into 3 groups: group 1 (control) - with a quadruple graft; group 2-with a simple triple graft; and group 3-with a braided triple graft.

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.

HOW TO PERFORM A META-ANALYSIS: A PRACTICAL STEP-BY-STEP GUIDE USING R SOFTWARE AND RSTUDIO.

Meta-analysis is an adequate statistical technique to combine results from different studies, and its use has been growing in the medical field. Thus, not only knowing how to interpret meta-analysis, but also knowing how to perform one, is fundamental today. Therefore, the objective of this article is to present the basic concepts and serve as a guide for conducting a meta-analysis using R and RStudio software.

Clinical outcomes of combined anterior cruciate ligament and anterolateral ligament reconstruction: a systematic review and meta-analysis.

Objectives: To compare the clinical outcomes of isolated anterior cruciate ligament (ACL) reconstruction with combined reconstruction of the ACL and anterolateral ligament (ALL) of the knee.

Methods: A search was conducted on the PubMed, Medline, Google Scholar, EMBASE, and Cochrane library databases, in line with the PRISMA protocol. The indexation terms used were "anterior cruciate ligament" OR "acl" AND "anterolateral ligament" AND "reconstruction.

Study of the Nerve Endings and Mechanoreceptors of the Anterolateral Ligament of the Knee.

Purpose: To describe the morphology and distribution of the anterolateral ligament of the knee (ALL) nerve endings, aiming to understand the interaction between the proprioceptive system and knee mechanics.

Methods: Twenty ALLs were obtained from fresh frozen cadavers. The ligaments were measured, weighed, and cut.

Anterolateral ligament of the knee: a step-by-step dissection.

Background: The number of studies and clinical interest in the anterolateral ligament of the knee (ALL) has grown in recent years. A meticulous and accurate ALL dissection is vital in anatomic and biomechanical studies, and a standardized technique is not yet established. As such, the aim of this study was to describe a step-by-step ALL dissection technique that could help authors consistently identify the ALL.

Anatomy of the Anterolateral Ligament of the Knee: A Systematic Review.

Purpose: To conduct a systematic literature review to search for studies on the anatomy of the anterolateral ligament (ALL) of the knee, presenting the most accepted findings, as well as the evolution of anatomic information on this structure.

Methods: We reviewed the PubMed, MEDLINE, and ClinicalKey databases for anatomic studies on the ALL, involving cadaveric, histologic, and biochemical dissection and/or anatomic imaging. The primary data researched were the presence of the ligament; measures of length, width, and thickness; ligament path; insertions; number of bands; histologic assessment; and innervation.

Anatomic Outside-In Reconstruction of the Anterior Cruciate Ligament Using Femoral Fixation with Metallic Interference Screw and Surgical Staples (Agrafe) in the Tibia: An Effective Low-Cost Technique.

Background: An anterior cruciate ligament (ACL) rupture is a frequent injury, with short and long-term consequences if left untreated. With a view to benefitting as many patients as possible and preventing future complications, we created a low-cost ligament reconstruction technique.

Method: The present article describes an anatomic ACL reconstruction technique.
