Aims
The results of revision surgery to correct leg-length discrepancy (LLD) after total hip arthroplasty (THA) are not clear. Only two previous small series have been published dealing with this issue. The aim of this retrospective study of revision THAs for LLD was to determine the postoperative change in LLD, the functional outcomes, and whether...
As an alternative to total hip arthroplasty (THA), hip resurfacing arthroplasty (HRA) has numerous advantages including low risk of dislocation, preservation of femoral bone stock, and no restrictions on high-impact sports. This study was designed to evaluate the results of HRA performed in patients under 30 years old with a long-term follow-up.
Al...
Aims:
Mechanical impingement of the iliopsoas (IP) tendon accounts for 2% to 6% of persistent postoperative pain after total hip arthroplasty (THA). The most common initiator is anterior acetabular component protrusion, where the anterior margin is not covered by anterior acetabular wall. A CT scan can be used to identify and measure this overhang...
Purpose:
Hip arthroplasty with metal-on-metal bearings like hip resurfacing results in the release of metallic ions. In parallel, like every metallic implant, knee arthroplasty implants undergo passive corrosion. We analyzed blood levels of cobalt and chromium ions in patients who have a hip resurfacing arthroplasty and compared them to patients w...
Mechanical irritation or impingement of the iliopsoas tendon accounts for 2–6% of persistent postoperative pain cases after total hip arthroplasty (THA). The most common trigger is anterior cup overhang. CT-scan can be used to identify and measure this overhang; however, no threshold exists for symptomatic anterior iliopsoas impingement. We conduct...
Introduction:
The relationship between the occurrence of a periprosthetic hip or knee joint infection, a post-surgical hematoma and the time to surgical revision, along with the need to take samples for microbiology analysis has not been clearly defined. This led us to perform a retrospective study to 1) define the rate of infected hematoma and su...
Introduction:
A considerable number of patients are not satisfied after total knee replacement (TKR) because of persistent pain. This pain can also be neuropathic in origin. Both types of pain have a large impact on function and quality of life. Furthermore, the trajectory of anxiety and depressive symptoms and pain catastrophizing has rarely been...
Introduction
L’arthroscopie de hanche est une intervention chirurgicale de plus en plus réalisée en France. Nous avons mené une étude rétrospective dans le but de décrire les conditions de réalisation de l’arthroscopie de hanche, étudier le taux de réintervention par arthroscopies et par arthroplastie, évaluer la fréquence des réadmissions pour com...
Background:
Knowledge of the antibiotic susceptibility profiles of the bacteria responsible for osteoarticular infections is crucial for choosing the appropriate empirical antibiotic regimen. Wide use of broad spectrum antibiotics in these infections may have lead to selection of resistant bacteria. The aim of our study was to answer to these ques...

L’instabilité fémoro-tibiale est une cause de reprise précoce des arthroplasties de genou. Elle peut être la conséquence d’une laxité fémoro-tibiale notamment dans le plan frontal avec une décoaptation fémoro-tibiale. Les radiographies standards postopératoires avec une décoaptation (lift-off) fémoro-tibiale peuvent-elles faire cra...
Introduction: Total hip resurfacing arthroplasty (THRA) is an alternative to conventional total hip replacement (THR) in young patients with osteonecrosis of the femoral head. Series have been small, without criteria regarding extent of necrosis, thus vitiating results. We therefore conducted a retrospective assessment of THRA for small necrosis, t...
Introduction: In 2005 and 2011, we reported results for a comparative study of two types of 28-mm bearing (metal-on-metal (MoM) and ceramic-on-polyethylene (CoP)) in active patients with respectively 5 and 12 years’ follow-up. The present report is an update at a mean 20 years’ follow-up, addressing 2 issues: 1) implant survival at a mean 20 years;...

Introduction
Le resurfaçage total de hanche (RTH) est une alternative aux prothèses totales de hanche (PTH) conventionnelles chez les jeunes patients présentant une ostéonécrose de la tête fémorale. Les séries sont assez limitées en nombre avec des critères d’inclusion ne comportant pas une limitation sur la taille de la nécrose ce qui rend...
Background:
Tibiofemoral instability is one reason for early revision of total knee arthroplasty. It can be the consequence of tibiofemoral laxity, especially in the coronal plane with tibiofemoral lift-off. But does femoral condyle lift-off on conventional postoperative radiographs suggest the presence of laxity or potential instability? To our k...
Introduction:
The ceramic-on-ceramic couple in total hip arthroplasties (THA) has the advantage of excellent wear resistance and the bioinert nature of its debris. Noise occurring from this friction torque is a common complication, the contributing factors of which are debated. The noise is caused by a lack of lubrication, due in most part to the...
Introduction:
The management of prosthetic joint infection (PJI) has been widely studied in the context of total hip arthroplasty (THA). However, the outcomes of debridement, antibiotics and implant retention (DAIR) for PJI have never been compared between hip resurfacing arthroplasty (HRA) and THA. This led us to carry out a retrospective case-co...
Resumen
Las infecciones nosocomiales o infecciones asociadas a la atención sanitaria (IAAS) que complican la cirugía ortopédica se encuentran en constante aumento. Las causas principales de este aumento son el envejecimiento progresivo de la población, que origina un número regularmente creciente de intervenciones quirúrgicas, y la imposibilidad de...
Introduction:
Total hip arthroplasty (THA) in young adults, especially in those with hip dysplasia, is affected by wear and acetabular fixation problems. Shelf acetabuloplasty is performed to delay THA in patients with acetabular dysplasia. Thus, we conducted a retrospective, continuous case-control study at a single healthcare facility to analyze...
Résumé
Introduction
Les infections ostéo-articulaires (IOAs) sur articulation native entrainent des lésions du cartilage pouvant nécessiter une arthroplastie ultérieure. Il n’existe pas d’attitude consensuelle quant à la réalisation systématique de prélèvements peropératoires à visée microbiologique lors de la réalisation d’une arthroplastie sur a...
Introduction: Osteoarticular infections (OAIs) of native joints lead to cartilage damage which may require subsequent arthroplasty. There is no consensus on systematic intraoperative microbiological sampling when performing an arthroplasty on a native joint with a history of OAI. We carried out a retrospective study to: 1) identify the frequency of...
Background
The optimal length of the intravenous antibiotic treatment of periprosthetic joint infections (PJIs) generally ranges from one to six weeks and is a matter of debate. Most antibiotics active against Gram-positive cocci (GPC) exhibit both high oral bioavailability and bone diffusion. Thus, early oral therapy may be a reasonable option in...
Introduction
Un registre national de vie réelle concernant la dalbavancine (DLB) a été réalisé sur l’année 2019. En participant à ce registre, nous voulions faire diffuser l’information contenue et évaluer nos pratiques. L’objectif de ce travail est d’évaluer l’utilisation de la DLB dans notre centre en se comparant au registre national.

Résumé
Background
Bien qu’étant l’examen de référence pour le diagnostic des infections péri-prothétiques (IPP), la ponction articulaire peut-être mise en défaut du fait d’agents infectieux de culture difficile, d’une antibiothérapie concomitante ou parfois du fait de ponctions répétées discordantes. Le BJI InoPlex™ (Diaxonhit) est un test immuno-...
Résumé
Contexte
Le diagnostic des infections périprothétiques (IPP) est essentiel pour la prise en charge des infections ostéoarticulaires. L’examen préopératoire de référence est la ponction articulaire dont le résultat est obtenu après un délai de culture de 2 à 14 jours avec un taux de faux négatifs non négligeable lié, en particulier, à la fra...
The genus Staphylococcus is the main causative agent of bone and joint infections (BJI) in which outcomes are impacted by both effective surgical and appropriate antimicrobial management. In this context, methicillin resistance (MR) detection is a microbiological challenge to optimize the anti-staphylococcal drug coverage and to secure the surgical...
Introduction: Knee arthrodesis utilizes an arthrodesis nail as a salvage technique for infected total knee arthroplasty (TKA), especially when the extensor mechanism is damaged, or the skin is compromised. This implant helps to minimize or prevent leg length discrepancy, while allowing immediate weight-bearing without requiring bone fusion. However...
Background: While joint aspiration is the benchmark for diagnosing periprosthetic joint infections (PJI), the results can be flawed because certain bacteria are difficult to culture, the patient is on concurrent antibiotic therapy or in some cases, repeated joint aspirations confer conflicting results. The BJI InoPlex; (Diaxonhit) is a multiplex EL...
Introduction: In cases of repeated treatment failure of periprosthetic joint infections (PJI) of the knee, above-the-knee amputation (AKA) or knee arthrodesis can be proposed to reduce the risk of recurrent infection, especially in cases with major bone defects or irreparable damage to the extensor mechanism of the knee. Since AKA versus knee arthr...
Background: Diagnosis of periprosthetic infection (PPI) is crucial for management of bone and joint infection. The preoperative gold-standard is joint aspiration, providing results after 2-14 days’ culture, with non-negligible false negative rates due to the fragility of certain micro-organisms and/or prior antibiotic treatment. The SynovasureTM al...
Background:
Patient-reported outcome measures such as the Oxford-12 Hip Score and Hip Disability and Osteoarthritis Outcome Score (HOOS) are used in daily orthopaedic practice to evaluate patients. Because different studies use different scores, it would be important to build conversion tables between scores (crosswalk) to compare the results of o...

Résumé
Si les cupules à double mobilité et les cupules rétentives permettent de stabiliser la plupart des luxations récidivantes des prothèses totales de hanche, elles sont parfois en défaut en cas de perte de l’appareil abducteur de la hanche. Pour répondre à ces situations complexes nous avons mis au point une technique originale de reconstructio...
Background: Revision of total knee arthroplasty (TKA) requires preoperative assessment to identify the causes of failure. Multidetector computerized tomography (MDCT) is a commonly used imaging technique, but is sensitive to certain artifacts, such as metal implants, limiting its use Cone-beam CT (CBCT)is a new technique dedicated to musculoskeleta...
Background: The impact of surgery on the patient is classically assessed on pre- and post-treatment scores. However, it is increasingly recommended to rank these results according to the Minimal Clinically Important Difference (MCID), using either the data distribution method or the anchor method, latter consisting in an extra question specifically...
Background: The HOOS and KOOS scoring questionnaires comprise respectively 40 and 42 items; a shorter 12-item version was recently developed, but remains to be validated in a French-speaking population. We therefore conducted a prospective study 1) to determine whether the new 12-item versions in French are equivalent to the longer HOOS and KOOS ve...
