Analysis of the distribution of mechanical load on the plate and lateral hinge of a valgus-producing open wedge high tibial osteotomy during weight-bearing by simulating consolidation. Finite element study.

Introduction: High tibial osteotomy (HTO) is indicated for managing isolated medial knee osteoarthritis in a young patient with a metaphyseal deformity of the proximal tibia. In a medial open-wedge HTO, maintaining the integrity of the hinge is crucial for consolidation and preservation of the correction. Based on a validated model and preliminary results, the objective of this work was to measure and monitor the distribution of mechanical load on a locking fixation plate and the lateral hinge of an HTO using a finite element (FE) model during different phases of consolidation evolution, simulating single leg weightbearing.

What is the lower limb length discrepancy after arthroplasty for proximal femoral fracture? A prospective, multicenter observational study of 590 hips.

Introduction: Lower limb length discrepancy (LLD) following hip arthroplasty after proximal femoral fracture (PFFA) is little studied. The aim of this work was to answer the following questions: 1) What are the incidence and mean values ​​of LLD after PFFA? 2) What are the clinical consequences (tolerance) of LLD after PFFA? 3) Can we identify risk factors for LLD after PFFA? 4) Is there a significant difference in terms of LLD after PFFA to treat intra- versus extra-capsular fractures?

Hypothesis: LLD after proximal femoral fracture arthroplasty is rare but has good clinical tolerance, given the low functional demands of the patients.

Patients And Methods: This is a multicenter prospective observational cohort study (15 centers), including 590 patients, operated on for hip arthroplasty for proximal femur fracture between May 2022 and June 2023.

Can we trust the accuracy of the automatic calibration of the EOS system to measure lower limb length inequality after total hip arthroplasty? Comparison of EOS versus manual measurement on 110 calibrated radiographs.

Introduction: Traditionally, to determine a length on a limb radiograph after total hip arthroplasty (THA), calibration is performed manually with the diameter of a ball or the femoral head. More recently, the development of EOS with automatic calibration has called into question the usefulness of manual calibration to highlight lower limb length inequality (LLLI). However, the validation of EOS with automatic calibration without landmarks to measure length inequalities on large images has not been verified against manual measurements on calibrated radiographs (conventional method), which motivated the present work.

[Shadowing as a pedagogical method for teaching interprofessional collaboration].

Shadowing enables us to follow individuals on a daily basis without disrupting the normal course of their activities. During their final year externship in a family doctor's practice, medical students from the University of Lausanne meet a patient at home and observe other professionals, thus enriching their understanding of collaborative practice. This approach fosters understanding of roles, teamwork and reflection on professional positioning.

Surgical site infection in severe trauma patients in intensive care: epidemiology and risk factors.

Background: Severe trauma is the leading cause of disability and mortality in the patients under 35 years of age. Surgical site infections (SSI) represent a significant complication in this patient population. However, they are often inadequately investigated, potentially impacting the quality of patient outcomes.

Hip and knee arthroplasty in one surgical session: early morbi-mortality study.

Introduction: Bilateral prosthetic hip or knee replacement in one surgical session is a procedure that has been widely validated in the literature, whereas hip and knee replacement in one surgical session remains poorly documented. This study reports on the results of these procedures by analyzing early post-operative complications in a retrospective multicenter study.

Material And Methods: Between 2009 and 2023, 51 patients underwent hip and knee replacement surgery in a single surgical session at 4 French centers.

[K-taping (coloured sticking adhesive bands): myth or reality?].

The use of Kinesiotaping (KT) has become common in the treatment and prevention of musculoskeletal injuries. This article covers the ten main myths encountered on a daily basis, examining the evidence from recent data (systematic reviews and meta-analyses). With current available data, there is a relative evidence regarding some effect upon short-term pain relief, improved mobility, better joint stability, drainage of edema, and improve muscle function.

[Posterior cruciate ligament rupture : state of the art].

Posterior cruciate ligament (PCL) ruptures can cause severe knee instability and disability and thus, appropriate management is crucial for the successful restoration of patients' knee function. Rupture of the PCL can occur during sporting activity but more often, as a part of high-energy trauma. The diagnosis can be made using various clinical tests, such as the posterior drawer test or the quadriceps active test.

Humeral head size predicts baseplate lateralization in reverse shoulder arthroplasty: a comparative computer model study.

Background: In reverse shoulder arthroplasty (RSA), the ideal combination of baseplate lateralization (BL), glenosphere size (GS), and glenosphere overhang (GOH) with a commonly used 145° neck shaft angle (NSA) is unclear. This is the first study evaluating correlations of body height (BH), humeral head size (HS), glenoid height (GH), and association of gender with best glenoid configurations for range of motion (ROM) maintaining anatomic lateralization (aLAT) for optimized muscle length in 145° and less distalized 135° RSA.

Methods: In this computer model study, 22 computed tomographies without joint narrowing were analyzed (11 male/female).

Minimally invasive surgery of femoral periprosthetic fractures increases the rate of consolidation and decreases time to bone healing without a higher rate of complications.

Background: Knee periprosthetic femoral fractures (KPPFF) are becoming more frequent due to the increasing number of arthroplasties and the aging population, for whom maintaining autonomy and function remains a challenge. The use of locking plates has improved functional results and promoted the development of "minimally invasive" surgical (MIS) approaches. Despite the availability of literature comparing between different types of osteosynthesis for KPPFF, there is a paucity of information available on the complications of osteosynthesis using locking plates, depending on the approach.

Medial meniscal repair in stable knees: Survival rate and risk factors for failure at a minimum of 5 years.

Introduction: The menisci play a major role in the protection of the knee against osteoarthritis. A medial meniscus (MM) tear occurring in a stable knee is more at risk of repair failure than a suture concomitant with reconstruction of the anterior cruciate ligament.

Hypothesis: The survival of MM sutures in stable knees depends on the type of lesion.

The frequency of medial meniscal repairs in stable knees during one year of arthroscopic activity (2021-2022) - comparison with a retrospective study (prior to 2017).

Introduction: There has been a significant increase in the use of conservative treatment for meniscal lesions due to raised awareness around the need for meniscal preservation. However, sutures of the medial meniscus (MM) in stable knees remain less frequently used. The objective of this study was to, firstly, identify the MM suture rate over one year of activity; secondly, to identify and compare the distribution of MM sutures in stable, and stabilized, knees on this prospective series; and thirdly, to compare the evolution of practices with a retrospective series of more than 5 years follow-up.
