Tibial plateau

PURPOSE: To identify MRI-detected anatomical risk factors for non-contact anterior cruciate ligament (ACL) injuries across genders. METHODS: A retrospective analysis was performed on 141 ACL-reconstructed patients (35 females, 106 males) and 142 controls (37 females, 105 males) from January 2020 to April 2022. Inclusion criteria were primary non-contact ACL injuries. The tibial plateau slope, lateral femoral condyle index, Insall-Salvati index, and patellar tendon angle were measured, using binary logistic regression for gender-specific risk evaluation...

Lateral tibial plateau fractures are generally present as depressed fractures. The lateral tibial plateau is more common than the medial tibial plateau, often due to a bumper injury. If depressed fragments are more than 8-10 mm, then surgical management is usually needed. Anterolateral fixation is frequently used for unicondylar lateral tibial plateau fractures. Here, we present an articular depressed lateral tibia plateau fracture in a Schatzker type 3 case. The fracture was managed through an anterolateral approach with sub-meniscal arthrotomy, allowing for direct visualization and subsequent fixation using bone cement and a cannulated cancellous screw...

BACKGROUND: The posterior cruciate ligament (PCL) attachment may be damaged in cruciate-retaining total knee arthroplasty (CR-TKA) using the complete resection for tibial preparation, and resection amount varies greatly among individuals. Discoid lateral meniscus (DLM) is one of the most common anatomic knee variants. This study aimed to evaluate the difference in PCL attachment sacrifice in CR-TKA between patients with and without DLM. METHODS: Fifty-one knees in the study group (DLM group) were matched 1:1 to 51 control knees (non-DLM group) by age, sex, and maximum width of the tibial plateau...

INTRODUCTION: There is still no consensus on the length of the non-bearing period required for tibial plateau fractures (TPFs) treated surgically. Several studies showed that full weight bearing immediately postoperatively does not affect fixation or cause joint collapse in patients with TPF. While there are concerns about weight bearing in the elderly due to fragile bone quality, their physical disability often makes it difficult to carry out activities of daily life when weight bearing is not allowed...

BACKGROUND: In recent years, the incidence of tibial plateau fracture has been on the rise, predominantly affecting the elderly population. Deep vein thrombosis may lead to poor prognosis in patients. the Systemic Inflammatory Response Index are novel biomarkers of inflammation, and this study aims to verify their predictive effect and construct the nomogram model. METHOD: This study used binary logistic regression analysis to predict the predictive effect of SIRI on the occurrence of DVT in tibial plateau fracture patients...

Osteoarthritis (OA) is now considered as a multifaceted disease affecting various articular tissues, including cartilage, bone, synovium, and surrounding ligaments. The pathophysiology strongly implicates intricate chemical communication, primarily through cytokines, leading to the production of degradative enzymes in cartilage, inflammatory peptides in synovium, and structural changes in bone, resulting in characteristic clinical features such as joint deformities and loss of cartilage space seen on X-rays...

This study aims to evaluate the morpho-functional change in the patellar ligament in dogs with cranial cruciate ligament disease. We hypothesized that it may show increased thickening and stiffness with increasing days from onset to diagnosis instead of trauma. Understanding this aspect has implications for the choice of timing for treating patients suffering from cranial cruciate ligament disease, as well as the contextualization of patellar ligament desmitis pictures after surgical treatment with tibial plateau leveling osteotomy or tibial tuberosity advancement...

Knee osteoarthritis is a whole joint disease highlighting the coupling of cartilage and bone adaptations. However, the structural properties of the subchondral bone plate (SBP) and underlying subchondral trabecular bone (STB) in the femoral compartment have received less attention compared to the tibial side. Furthermore, how the properties in the femoral compartment relate to those in the corresponding tibial site is unknown. Therefore, this study aimed to quantify the structural bone and cartilage morphology in the femoral compartment and investigate its association with those of the tibial plateau...

BACKGROUND: Little is known on how meniscal morphology develops during skeletal growth and maturation and its subsequent relationship with the corresponding bony anatomy. HYPOTHESES: (1) Meniscal dimensions and morphology would change by age during skeletal growth and maturation in different ways in boys compared with girls. (2) Morphological features of the medial and lateral menisci would correlate to medial and lateral femoral condyle curvatures. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

BACKGROUND: This study investigated the biomechanical properties of a new plate used for the treatment of posterolateral tibial plateau fractures using finite element analysis. METHODS: The study groups were as follows: group PM, model of the new plate with posteromedial tibial plateau fracture; group PL, model of the new plate with posterolateral tibial plateau fracture; and group PC, model of the new plate with posterior tibial plateau fracture. We used two loading modes: uniform loading on the entire plateau, and loading on the posterior plateau...

PURPOSE: The aim of this study was to investigate whether the whole tibial spine volume and femoral intercondylar notch volume are risk factors for anterior cruciate ligament (ACL) injury. The hypothesis was that the whole tibial spine volume and femoral notch volume would be smaller in athletes who sustained ACL injury than in athletes with no history of ACL injury. METHODS: Computed tomography scans of both knees were acquired and three-dimensional bone models were created using Mimics to measure whole tibial spine volume and femoral notch volume...

OBJECTIVE: To report the surgical approaches and stabilization of lateral and medial tibial plateau fractures (TPF), as well as the long-term outcome following repair. STUDY DESIGN: Prospective series of three client-owned dogs. ANIMALS: Three dogs. METHODS: For the two lateral TPF cases (Unger type 41-B1), the surgical approach included separation of the lateral collateral ligament and long digital extensor tendon. The lateral meniscus was elevated to allow visualization of the tibial surface and assess fracture reduction...

Meniscus tears are classified as horizontal, longitudinal, radial, and complex tears. Flap tears are a specific form in which a portion of the meniscus is displaced from a horizontal or longitudinal tear. The question of whether it is possible to preserve the meniscus by meniscus repair is of crucial therapeutic importance. It is therefore important to specify not only the configuration of the tear but also its extent and location as precisely as possible. Cooper's zonal classification should also be used for this purpose...

OBJECTIVE: This study analyzes the therapeutic effect of arthroscopy-assisted minimally invasive surgery in patients with tibial plateau fractures (TPFs) and its influence on knee function and range of motion (ROM) recovery. METHODS: This study enrolled 84 patients with TPFs admitted to the researchers' hospital between March 2021 and May 2022 as the study subjects, including 42 patients treated with open reduction and internal fixation (observation group) and 42 patients treated with arthroscopy-assisted minimally invasive surgery (experimental group)...

OBJECTIVE: To explore clinical efficacy of autologous bone grafts and bone substitute for the treatment of tibial plateau fractures by Meta analysis. METHODS: Controlled clinical studies on autogenous bone transplantation and bone substitutes in treating tibial plateau fractures published on PubMed,Web of Science,CNKI,Wanfang and other databases from January 2005 to August 2022 were searched by computer. Literature screening and data extraction were performed according to randomized controlled trial(RCT),and the quality of RCT were evaluated by using intervention meta-analysis criteria in Cochrane manual...

PURPOSE: The purpose of this study was to find out whether the torsions of the femur and tibia are dependent on the coronal plane alignment of the knee (CPAK) type. METHODS: Five hundred patients (1000 legs) were included, who received a whole leg standing three-dimensional (3D) radiograph using EOS imaging (EOS Imaging, Paris, France). SterEOS software was used for digital reconstruction. Femoral and tibial torsions were determined by analysing 3D reconstructions of each leg...

BACKGROUND: Detailed knowledge of the anatomic course of the common peroneal nerve (CPN) is crucial for the surgical treatment of the posterolateral corner (PLC) of the knee. PURPOSE: To investigate the relationship of the CPN to the PLC of the knee at different flexion angles. STUDY DESIGN: Descriptive laboratory study. METHODS: Ten healthy volunteers were recruited to undergo magnetic resonance imaging (MRI) of the knee joint at knee flexion angles of 0°, 30°, 60°, 90°, and 120°...

Mimicking anisotropic features is crucial for developing artificial load-bearing soft tissues such as menisci). Here, a high-density hydrogen bond locking (HDHBL) strategy, involving preloading a poly(N-acryloylsemicarbazide) (PNASC) hydrogel with an aqueous solution containing a hydrogen bond breaking agent, followed by water exchange, to fabricate anisotropic high-strength hydrogels are proposed. During this process, multiple high-density hydrogen bonds of the PNASC network are re-established, firmly freezing oriented molecular chains, and creating a network with an anisotropic microstructure...

Schatzker III tibial plateau fractures (TPF) reduction and stabilization still represents a challenging procedure. We present an alternative, percutaneous surgical technique. With an antero-medial transverse incision at the level of the tibial metaphysis, under fluoroscopic control, an osteotome is advanced from medial to lateral, under the depressed fragments, reducing the articular surface of the lateral TP anatomically, without creating a significant void and preserving the lateral wall. Final fixation is achieved with screws placed from lateral to medial in a percutaneous fashion, parallel to the articular surface to hold fragments in a rafting way...

PURPOSE: The aim of this study was to analyse the functional outcome and the conversion rate to total knee arthroplasty (TKA) after surgically treated tibial plateau fractures (TPF). METHODS: All patients undergoing surgical treatment of TPF at a single institution between January 2003 and December 2019 were retrospectively reviewed. The Knee injury and Osteoarthritis Outcome Score (KOOS) and Tegner activity scale (TAS) were collected. The conversion rate to TKA was examined 2, 5, 7 and 10 years after surgical treatment of TPF...
