Differences in Clinical Outcomes and Rotational Stability Between Anterolateral Ligament Reconstruction and Lemaire Lateral Tenodesis Following Primary Anterior Cruciate Ligament Reconstruction.

Objectives: Residual instability following anterior cruciate ligament reconstruction (ACLR) is a common concern among young, active patients. Currently, two primary methods are used to address this matter: anterolateral ligament reconstruction (ALLR) using a graft and lateral extra-articular tenodesis (LET). This study aims to compare the Lemaire method for LET with ALLR in minimizing rotational instability after ACLR.

Effect of Adding Stem Extension to a Short-Keeled Knee Implant on the Risk of Tibial Loosening: a Historical Cohort Study.

Background: Short-keeled tibial implants may be at higher risk of aseptic loosening. Stem augmentation has been suggested to improve its fixation. We aimed to assess whether this technique could decrease the loosening rate of such tibial implants.

Aspirin is as effective as low molecular weight heparins in preventing symptomatic venous thromboembolism following arthroscopic anterior cruciate ligament reconstruction.

Objective: The optimal agent for thromboprophylaxis following arthroscopic anterior cruciate ligament reconstruction (ACLR) remains unclear, particularly in patients with a low baseline risk for venous thromboembolism (VTE). This retrospective cohort study aims to compare the effectiveness and safety of aspirin versus low molecular weight heparins (LMWHs) in this specific patient population.

Methods: We analyzed data from patients who underwent ACLR between March 2016 and March 2021, focusing on those with a low risk for VTE.

Knee Flexion Deformity and Increased Posterior Tibial Slope Associated with Osgood Schlatter Disease: A Case Report and Review of Literature.

Genu recurvatum associated with Osgood-Schlatter disease (OSD) has been reported in several studies. In this report, we describe a rare complication of a case of OSD with flexion contracture (tfighat is the exact opposite of the knee deformity classically associated with OSD) and increased posterior tibial slope. In the current article, we report a 14-year-old case of OSD referred to our center with a fixed knee flexion contracture.

Using Blumensaat's line to determine the sagittal alignment of the distal femur.

Background: A coherent measurement approach for sagittal alignment of the distal femur after fracture reduction or distal femur osteotomies is not available. The present study aims to introduce a new method using Blumensaat's line and tangent lines to the femoral cortexes to determine the sagittal alignment of the distal femur.

Methods: 113 patients who had true lateral knee radiographs were included.

Five databases were searched to find relevant papers on April 29, 2020, including, PubMed, Scopus, EMBASE (Ovid), Science Citation Index, and COCHRANE Central Register for Controlled Trials (CENTRAL). Randomized controlled trials (RCTs) and nonrandomized-controlled-trials (non-RCTs), such as interrupted time series and prospective cohort studies were included.

Evaluation of early complications, outcome, and mortality in Coronavirus Disease 2019 (COVID-19) infection in patients who underwent orthopedic surgery.

Background: A higher mortality and morbidity rate has been reported in COVID-19 patients undergoing surgery. To reduce the morbidity and mortality rate in COVID-19 patients undergoing orthopedic procedures, we aimed to increase the threshold for surgical planning.

Methods: In a prospective cohort study, COVID-19 patients who underwent elective or emergent orthopedic surgery in three orthopedic surgery centers from February 2020 to September 2020 were included.

Anatomic reconstruction of the medial collateral ligament in multi-ligaments knee injury using achilles allograft : a modification of Marx's technique.

Medial Collateral Ligament (MCL) injury may require operative treatment. Marx et al. described the latest technique for reconstruction of MCL.

The Efficacy of Intravenous Versus Topical Use of Tranexamic Acid in Reducing Blood Loss after Primary Total Knee Arthroplasty: A Randomized Clinical Trial.

Background: Blood loss during and immediately after total knee arthroplasty (TKA) is among the most challenging concerns. It has been demonstrated that Tranexamic acid (TXA) can help to reduce perioperative blood loss. TXA can be used as an oral, topical or intravenous injection.

Short-term results of triathlon cementless versus cemented primary total knee arthroplasty.

Background: Recent studies have demonstrated that aseptic loosening remains a leading cause of failure after total knee arthroplasty (TKA). Cementless fixation is a possible strategy for countering this problem. This study compared short-term survivorship and functional results of patients undergoing primary TKA with cementless versus cemented implants.

Symptomatic Benign Prostatic Hyperplasia: A Risk Factor for Periprosthetic Joint Infection in Male Patients.

Background: Male patients undergoing total joint arthroplasty have a higher risk of periprosthetic joint infection (PJI) compared with female patients. The exact reason for this finding is not well known. This study aimed to determine if patients with symptomatic benign prostatic hyperplasia (BPH) are at increased risk of PJI.

Comparison of Postoperative Complications and Survivorship of Total Hip and Knee Arthroplasty in Dialysis and Renal Transplantation Patients.

Background: Chronic renal failure (CRF) is an established risk factor for surgical site infection (SSI) and periprosthetic joint infection (PJI) after primary total joint arthroplasty. However, there is limited literature comparing outcomes between patients who receive dialysis vs renal transplantation. We examined and compared clinical outcomes of patients receiving dialysis vs those who had a prior renal transplantation.

Tranexamic Acid Is Associated With Reduced Periprosthetic Joint Infection After Primary Total Joint Arthroplasty.

Background: Previous studies have demonstrated preoperative anemia to be a strong risk factor for periprosthetic joint infection (PJI) in total joint arthroplasty (TJA). Allogeneic blood transfusion can be associated with increased risk of PJI after primary and revision TJA. Tranexamic acid (TXA) is known to reduce blood loss and the need for allogeneic blood transfusion after TJA.

Highlighting the Roles of Anemia and Aspirin in Predicting Ninety-Day Readmission Following Aseptic Revision Total Joint Arthroplasty.

Background: Revision total joint arthroplasties (TJAs) are associated with an increased rate of complications. To date, it is unclear what drives readmission after aseptic revision arthroplasty and what measures can be taken to possibly avoid them. The purpose of this study is to (1) determine the reasons for readmission after aseptic revision TJA and (2) identify patient-specific or postoperative risk factors through a multivariate analysis.

Reverse Segond Fracture without Posterior Cruciate Ligament Injury - A report of Two Cases and Review of the Literature.

Introduction: Reverse Segond fracture is a cortical avulsion fracture off the medial tibial plateau of the knee, associated with tears of the posterior cruciate ligament (PCL), medial collateral ligament (MCL), medial meniscus, and probably the anterior cruciate ligament (ACL). Unlike Segond fracture, it is a very rare injury of the knee.

Case Report: Case one is a 24-year-old male with left tibial plateau and reverse Segond fracture with an magnetic resonance imaging (MRI) showing MCL avulsion, medial meniscus entrapped in fracture site and ACL tear but intact PCL.

Relationship between electromyographic activity of knee joint muscles with vertical and posterior ground reaction forces in anterior cruciate ligament reconstructed patients during a single leg vertical drop landing task.

The objective of the present study is to examine the relation between activity patterns of knee joint muscles with vertical and posterior ground reaction forces (VGRF and PGRF, respectively) in patients after anterior cruciate ligament reconstruction (ACLR). Twenty males post-ACLR participated in this cross-sectional study. The association between muscle activity with VGRF and PGRF was assessed during a single leg vertical drop-landing task.

The Effect of Gentamycin in the Irrigating Solution to Prevent Joint Infection after Anterior Cruciate Ligament (ACL) Reconstruction.

Background: Arthroscopic reconstruction of ACL is an effective method to restore knee stability after ACL rupture. Postoperative septic arthritis (SA) is very uncommon while the incidence of serious complications range between 0.14% and 1.

Different References for Valgus Cut Angle in Total Knee Arthroplasty.

Background: The valgus cut angle (VCA) of the distal femur in Total Knee Arthroplasty (TKA) is measured preoperatively on three-joint alignment radiographs. The anatomical axis of the femur can be described as the anatomical axis of the full length of the femur or as the anatomical axis of the distal half of the femur, which may result in different angles in some cases. During TKA, the anatomical axis of the femur is determined by intramedullary femoral guides, which may follow the distal half or near full anatomical axis, based on the length of the femoral guide.

Anatomical axes of the proximal and distal halves of the femur in a normally aligned healthy population: implications for surgery.

Background: The anatomical axis of the femur is crucial for determining the correct alignment in corrective osteotomies of the knee, total knee arthroplasty (TKA), and retrograde and antegrade femoral intramedullary nailing (IMN). The aim of this study was to propose the concept of different anatomical axes for the proximal and distal parts of the femur; compare these axes in normally aligned subjects and also to propose the clinical application of these axes.

Methods: In this cross-sectional study, the horizontal distances between the anatomical axis of the proximal and distal halves of the femur and the center of the intercondylar notch were measured in 100 normally aligned femurs using standard full length alignment view X-rays.
