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.

Hip preservation surgery for borderline and frank dysplasia: an overview of systematic reviews.

Purpose: To identify, synthesise, and critically appraise findings of systematic reviews and/or meta-analyses on hip preservation surgeries for borderline and/or frank dysplasia with or without concomitant femoroacetabular impingement (FAI).

Methods: A search, following the PRISMA guidelines, was conducted using Medline and Embase on 19/04/2023. Findings extracted from eligible studies were tabulated and synthesised.

Which treatment in acetabular fractures of the elderly: Osteosynthesis, osteosynthesis-THA or orthopedic treatment? 2-years retrospective outcomes of a therapeutic algorithm.

Introduction: Acetabular fractures account for 7% of osteoporotic fractures, with an epidemiological peak between 75 and 80 years of age. The aim of this study is to evaluate the results of treatment of these fractures in a population aged over 65.

Hypothesis: Surgical treatment would lead to better survival and functional outcomes in the management of acetabular fractures in subjects aged over 65.

Do prospective randomized controlled trials comply with filed protocols? Spin study of 206 trials from 2010 to 2023.

Introduction: Prospective randomized controlled trials (RCT) have a robust methodology, but some distortions may occur during the course of study. Some protocols may not be available at the time an article is reading. Some authors may change the methodology between the time the protocol was submitted and when the trial results are actually published.

Functional outcomes and center of rotation restoration in total hip arthroplasty after acetabular fracture: A review of 367 hips.

Background: Total hip arthroplasty (THA) after acetabular fracture is typically performed months or years later for posttraumatic arthritis after initial conservative treatment. But THA can be performed earlier after open reduction and internal fixation (ORIF) of the fracture. The aim of this study was to determine which strategy is best.

Shoulder Stabilization Technique Using the Medial Glenohumeral Ligament in Patients With the Buford Complex.

The Buford complex is an anatomic variation defined as the association of a cordlike middle glenohumeral ligament (MGHL) and an absent anterosuperior labrum. It can be challenging to properly identify on preoperative imaging and remains mostly an arthroscopic finding. It may, however, lead to problematic situations when encountered during an arthroscopic soft-tissue stabilization procedure, as the treatment of choice in such cases is a bone block.

Radiological signs of femoroacetabular impingement are linked to pelvic version in asymptomatic subjects.

Introduction: With the recent interest in hip-spine relationship, the link between femoroacetabular impingement (FAI) and the lumbar-pelvic-femoral complex (LPFC) appears decisive. The objectives of this study were (1) to compare the pelvic version, as well as (2) all the parameters of the LPFC between two populations of healthy subjects, comparing those with radiological signs of FAI to those without and finally, (3) to evaluate the LPFC parameters according to the type of FAI.

Hypothesis: Asymptomatic subjects with radiological signs of FAI had superior pelvic anteversion.

Does combined anterior cruciate ligament and anterolateral ligament reconstruction improve return to sport?

Purpose: Only 50-65% of patients return to their previous sporting level after ACL rupture. The literature reports a reduced rate of graft rupture when an anterolateral ligament reconstruction (ALLR) is associated with ACL reconstruction. ACL reconstruction combined with ALL allows a higher return to sport at pre-injury level than isolated reconstruction in patients playing pivot-contact sports.

The influence of the sacral slope on pelvic kinematics and clinical manifestations in femoroacetabular impingement.

Introduction: The radiological study of the sagittal alignment of the spine in static and dynamic positions has allowed a better understanding of the clinical results of total hip prostheses. According to the Roussouly classification, the sacral slope in a standing position characterizes the patient with a stiff spine (less than 35̊) or a flexible spine (greater than 35̊). The objectives of this study were to compare, in a population of patients operated on for femoroacetabular impingement (FAI), firstly, the kinematics of the lumbar-pelvic-femoral complex and secondly, the clinical presentation depending on whether the spine is stiff or flexible.

Labral tears in hip dysplasia and femoroacetabular impingement: A systematic review.

Introduction: Hip dysplasia and femoroacetabular impingement are pathologies whose impact on the function and survival of the hip joint is no longer debated. Labral tears may be present and impact the prognosis of the causal pathology. Labral tear management lacks consensus and still raises several questions, thus we conducted a systematic analysis to clarify: 1) What is its prevalence in hip dysplasia and femoroacetabular impingement? 2) Does it modify the symptomatology of the causal pathology? 3) Is its repair better than resection or abstention?

Material And Method: A systematic literature review was carried out following the PRISMA guidelines, using the Medline and Embase databases and including all articles in French or English, written until June 2022 referring to labral tears in hip dysplasia and femoroacetabular impingement.

Experimental study of risk of medial hinge fracture during distal femoral varus osteotomy.

Introduction: Lateral opening wedge distal femoral osteotomy (LOWDFO) is indicated for isolated lateral osteoarthritis in the valgus morphotype. Medial hinge fracture is a factor for poor prognosis. The present study had two aims: (1) to assess the impact of a temporary K-wire on hinge fracture risk; and (2) to assess the impact of LOWDFO opening speed.

Functional recovery after total hip/knee replacement in obese people: A systematic review.

Objective: Several studies have investigated the influence of body mass index (BMI) on functional gain after total hip replacement (THR) or total knee replacement (TKR) in osteoarthritis, with contradictory results. This systematic literature review was conducted to ascertain whether obesity affects functional recovery after THR or TKR in the short (<1 year), medium (<3 years) and long term (>3 years).

Methods: The study was registered with PROSPERO and conducted according to the PRISMA guidelines.

Slope-decreasing anterior closing wedge proximal tibial osteotomies using the freehand technique are accurate to within 2̊.

Introduction: Anterior cruciate ligament (ACL) reconstruction requires a detailed analysis of the posterior tibial slope (PTS) as excessive values may cause the reconstruction to fail and require a slope-decreasing anterior closing wedge tibial osteotomy combined with revision of the failed ACL reconstruction. The main purpose of this study was to assess the accuracy of correction after slope-decreasing anterior closing wedge tibial osteotomy in cases of chronic anterior instability caused by ACL rerupture.

Materials And Methods: This single-center retrospective study included 19 patients (20 knees) operated on by slope-decreasing anterior closing wedge tibial osteotomy combined with a second revision ACL reconstruction.

Experimental investigation of the risk of lateral cortex fracture during valgus tibial osteotomy.

Background: Valgus-producing medial opening-wedge proximal tibial osteotomies (V-MOW-PTO) are used to treat isolated medial-compartment knee osteoarthritis in patients with varus malalignment. A fracture of the lateral cortical hinge is a risk factor for poor outcomes. Implantation of a protective K-wire has been suggested to prevent this complication.

Comparison of five methods for locked-plate fixation of complex diaphyseal fractures.

Background: Peri-prosthetic fractures (PPFs) are steadily rising in number due to population ageing and increased performance of joint replacement procedures. Although PPFs without implant loosening are usually managed by internal fixation, no consensus exists regarding the optimal construct. The primary objective of this study was to compare five constructs, and the secondary objective was to compare sub-groups of mono-cortical screw constructs, with the goal of identifying the method most appropriate for diaphyseal fracture fixation when prosthetic material is present within the intra-medullary canal.

Patient specific instrumentation allow precise derotational correction of femoral and tibial torsional deformities.

Background: Rotational malalignment deformities of the lower limb in adults mostly arise from excessive femoral anteversion and/or excessive external tibial torsion. The aim of this study was to assess the correction accuracy of a patient specific cutting guides (PSCG) used in tibial and femoral correction for lower-limb torsional deformities.

Methods: Forty knees (32 patients) were included prospectively.

Gait analysis dataset of healthy volunteers and patients before and 6 months after total hip arthroplasty.

Clinical gait analysis is a promising approach for quantifying gait deviations and assessing the impairments altering gait in patients with osteoarthritis. There is a lack of consensus on the identification of kinematic outcomes that could be used for the diagnosis and follow up in patients. The proposed dataset has been established on 80 asymptomatic participants and 106 patients with unilateral hip osteoarthritis before and 6 months after arthroplasty.

Coronal and sagittal alignment of the lower limb in Caucasians: Analysis of a 3D CT database.

Introduction: Lower limb alignment is a major determinant of long-term outcomes after osteotomy or total knee replacement. The aim of this paper is to define the mean values of coronal and sagittal lower limb alignment for Caucasians as a function of sex using 3D reconstructions from CT-scans.

Materials And Methods: The analysis involved 586 Caucasian patients (269 males and 317 females) who had their hip-knee-ankle angle (HKA), lateral distal femoral angle (LDFA), medial proximal tibial angle (MPTA), posterior proximal tibial angle (PPTA), lateral and medial proximal posterior tibial angles (LPPTA/MPPTA), posterior distal femoral angle (PDFA), and non-weightbearing joint convergence angle (nwJLCA) measured.

Is the lateral tibial spine a reliable landmark for planning tibial or femoral valgus osteotomies?

Introduction: A valgus osteotomy around the knee is a conservative procedure performed to unload the medial tibiofemoral compartment. However, the optimal postoperative alignment target remains controversial. Many studies have applied a "Fujisawa point" at 62.

Arthroscopic Trillat technique for chronic post-traumatic anterior shoulder instability: outcomes at 2 years of follow-up.

Background: The purpose of this study was to assess the outcomes of a new arthroscopic Trillat technique at a 2-year follow-up. Our current hypothesis was that this technique could be used for the effective treatment of chronic post-traumatic unidirectional anterior shoulder instability, and that the recurrence and complication rates, external rotation, and functional outcomes would be as good as those of the reference technique.

Methods: Between April 2012 and August 2016, all patients older than 16 years who underwent the arthroscopic Trillat technique for unidirectional chronic post-traumatic anterior shoulder instability at the Dijon University Hospital (France), after the failure of well-conducted medical and rehabilitation treatment with at least 24 months of follow-up, were included.
