Microplastics exhibit accumulation and horizontal transfer of antibiotic resistance genes.

Although the fates of microplastics (0.1-5 mm) in marine environments and freshwater are increasingly studied, little is known about their vector effect in wastewater treatment plants (WWTPs). Previous studies have evaluated the accumulation of antibiotic resistance genes (ARGs) on microplastics, but there is no direct evidence for the selection and horizontal transfer of ARGs on different microplastics in WWTPs.

Complex Repair and Cruciate Ligament Reconstruction in KDs III and IV Multiligamentous Knee Injuries-Results of Mid-Term Follow-up.

The purpose of the present study was to describe the longitudinal outcomes of acute repair of extra-articular structure and anatomical reconstruction of cruciate ligament for knee dislocations (KDs) III and IV multiligamentous knee injuries. Forty-seven patients with an acute KD III or IV were treated with one-stage management within 9.2 days.

An Arthroscopic-Assisted Radial Meniscal Tear Repair Using Reinforced Suture Tape Rebars and Suture Tapes.

A radial tear of the meniscus can lead to significant loss of meniscus function, resulting in deleterious cartilage changes. Repair of radial meniscus tears has several challenges, including suture pull-out, which can reduce healing success. We present an arthroscopic repair technique in a complete radial lateral meniscus tear using vertical reinforced bars (rebar) of suture tapes to reduce suture pull-out and approximate the radial tear.

Application of Personalized Navigation Templates to Oxford Single Condylar Replacement in a Chinese Population.

The purpose of this study is to develop and validate a novel patient-specific navigational template for unicompartmental knee arthroplasty (UKA). A total of 120 patients who underwent UKA were randomized and divided into the conventional method and navigational template groups. In the navigational template group, patient-specific navigational templates were designed and used intraoperatively to assist 60 patients with UKA.

Tension Band Wire Fixation Technique for Anterior Cruciate Ligament Tibial Avulsion Fracture: A New Fixation Technique.

This study evaluated clinical results of tension band wire fixation technique in the arthroscopic treatment of anterior cruciate ligament (ACL) tibial avulsion fracture. This study included 148 cases of ACL tibial avulsion fracture treated using arthroscopic tension band wire fixation technique. Patients were followed up for 25 to 36 months with an average of 27 months and evaluated in accordance with the International Knee Documentation Committee (IKDC) and Lysholm knee scoring scale.

Accuracy and efficacy of osteotomy in total knee arthroplasty with patient-specific navigational template.

This study develops and validates a novel patient-specific navigational template for total knee arthroplasty (TKA). A total of 70 patients who underwent TKA were randomized and divided into conventional method group and navigational template group. In the navigational template group, the patient-specific navigational templates were designed and used intraoperatively to assist 35 patients with knee arthroplasty.

Novel patient-specific navigational template for total knee arthroplasty.

Current techniques for total knee arthroplasty have certain drawbacks, including violation of the intramedullary canals and limited accuracy. The aim of this research was to develop and validate the accuracy of a new computer-assisted preoperative planning concept for the creation of patient-specific navigational templates to replace conventional instruments. Volumetric computerized tomography (CT) scanning was performed on 30 cadaveric knees, and a three-dimensional reconstruction model of each knee was generated from the scan data.

Tension band wire fixation for anterior cruciate ligament avulsion fracture: biomechanical comparison of four fixation techniques.

Purpose: The purpose of this study is to design a new fixation method to treat tibial eminence fractures and assess its stability compared with conventional fixation methods.

Methods: Eighty fresh porcine knees were stripped of all soft tissue, leaving intact only the femur-anterior cruciate ligament (ACL)-tibia complex. A standardized type III fracture was simulated at the anterior cruciate ligament attachment region using an osteotome.
