Change in spinopelvic mobility 3 months after THA using a direct anterior approach.

Introduction: Spinopelvic kinematics, reflected by the change in spinopelvic tilt (ΔSPT) from a standing position to a flexed seated position, has been associated with the risk of prosthetic impingement and hip dislocation. Some studies have suggested changes in spinopelvic mobility after total hip arthroplasty (THA), but none have explored changes in mobility in the first three months following THA using a direct anterior approach.

Hypothesis: Our hypothesis was that changes in spinopelvic mobility occur in the first 3 months postoperatively, leading to increased hip mobility and increased spinopelvic kinematic abnormalities.

One-stage exchange strategy with extensive debridement for chronic periprosthetic joint infection following total knee arthroplasty is associated with a low relapse rate in non-selected patients: a prospective single-center analysis.

Purpose: This prospective clinical cohort was undertaken to determine the long-term risks of reinfection and all-cause aseptic failure after 1-stage exchange total knee arthroplasties (TKA) in a large series of consecutive patients with periprosthetic joint infection (PJI) following TKA.

Hypothesis: One-stage exchange for chronic PJI is an effective strategy, even in a non-selected population.

Patients And Methods: Non-selected patients (152 with 154 PJI) undergoing 1-stage-exchange TKA for PJI (January 2003-August 2015) were prospectively included and monitored for ≥2 years.

Comparison of survival between cemented vs cementless unicompartimental knee arthroplasty: a case control study with propensity score matching.

Introduction: The first results of cementless prosthesis were rather disappointing. However recent progress in methods of cementless fixation of prosthesis should lead to better results in terms of survival of these prostheses. The main objective is to compare the survival rate at last follow-up of UKA with cemented tibial or cementless.

Accuracy of Preoperative 3D vs 2D Digital Templating for Cementless Total Hip Arthroplasty Using a Direct Anterior Approach.

Background: An important aspect of preoperative planning for total hip arthroplasty is templating. Although two-dimensional (2D) templating remains the gold standard, computerized tomography (CT)-based three-dimensional (3D) templating is a novel preoperative planning technique. This study aims to compare the accuracy of a 2D and 3D plan using an anterior approach for the placement of the same uncemented prosthesis.

Revision total hip arthroplasty by a ceramic bearing surface after a third- and fourth-generation ceramic head or liner fracture.

Purpose: Although rare, fractures of ceramic components are difficult to revise, mainly due to the presence of residual ceramic debris that can cause catastrophic wear of the replacement components. Modern ceramic-on-ceramic bearings are suggested to improve outcomes of revision total hip arthroplasty (THA) for ceramic fractures. However, there are few published reports of mid-term outcomes of revision THA using ceramic-on-ceramic bearings.

Risk Factors Associated With Femorotomy or Fracture During Cementless Stem Removal and Generation of an Individual Predictive Risk Score.

Background: Femorotomy is a commonly used technique during cementless stem removal but should be preferred in selective revision cases to prevent intraoperative femoral fracture associated with deteriorated clinical outcome. Our aim was to assess the risk factors for fracture or femorotomy and develop a predictive risk stratification score.

Methods: A monocentric retrospective cohort including 202 patients was analyzed.

One-Stage Exchange Arthroplasty for Fistulizing Periprosthetic Joint Infection of the Hip: An Effective Strategy.

Prosthetic hip infection (PHI) is a disastrous scenario after an arthroplasty. International guidelines contraindicate one-stage exchange arthroplasty for fistulizing chronic prosthetic hip infection (FCPHI), nevertheless few surgical teams, mostly from Europe, support one stage procedure for this indication. Analysis of infection recurrence and implant failure of a series of FCPHIs treated with one stage arthroplasty.

Haematogenous prosthetic knee infections: Prospective cohort study of 58 patients.

Background: Prosthetic joint infection (PJI) is a rare (incidence, 0.15% to 0.9%) but serious complication of knee arthroplasty.

Curative treatment of prosthetic joint infection in patients younger than 80 vs. 80 or older.

Objective: Prosthetic joint infection (PJI) is a serious complication of joint replacement surgery. The major pharmacological and surgical treatments required by PJI increase the risk of peri-operative complications in elderly patients. The increase in life expectancy combined with procedural advances make these treatments possible even in the oldest patients.

Prosthetic joint infections due to Mycobacterium tuberculosis: A retrospective study.

Objective: Tuberculous prosthetic joint infection (PJI) is uncommon and often diagnosed late. The objective here is to describe the management of tuberculous PJI at an osteoarticular infection referral center.

Methods: A single-center retrospective study of patients managed between 1987 and 2016 was performed.

Concomitant Multiple Joint Arthroplasty Infections: Report on 16 Cases.

Background: Concomitant infections of several prostheses are very rare, serious events that pose particular medical and surgical therapeutic challenges. This study was undertaken to describe epidemiologic, clinical, and microbiological characteristics of concomitant multiple joint arthroplasty infections, their treatments, and outcomes.

Methods: Retrospective (January 2000 and January 2014), single-center, cohort study in a referral center for bone and joint infections.

Perceived Work Conditions and Turnover Intentions: The Mediating Role of Meaning of Work.

Perceived working conditions lead to various negative outcomes for employee behaviors, including turnover intentions. Although potential mediators for these relationships were previously identified, the importance of meaning of work has not yet been investigated. This study examines the role of this psychological resource as a mediator for the relationships between perceived working conditions and turnover intentions in a sample of 336 French workers from different job contexts.

Crystal-induced arthritis after arthroplasty: 7 cases.

Objectives: To describe the occurrence in prosthetic joints of crystal-induced arthritis (CIA) defined as the deposition within the synovial membrane and/or joint cavity of calcium pyrophosphate dehydrate (CPPD) (chondrocalcinosis), sodium urate (gout), or hydroxyapatite.

Methods: We retrospectively reviewed the 7 cases of prosthetic-joint CIA seen between 1993 and 2013 at a medical-surgical center specialized in the management of osteoarticular infections.

Results: The 4 females and 3 males ranged in age from 67 to 79 years.

Infection recurrence factors in one- and two-stage total knee prosthesis exchanges.

Purpose: Revision of infected total knee replacements (TKR) is usually delayed for a period in which the joint space is filled with an antibiotic-loaded acrylic spacer. In contrast, one-stage re-implantation supposes immediate re-implantation. Formal comparisons between the two methods are scarce.

Chronic infection of unicompartmental knee arthroplasty: one-stage conversion to total knee arthroplasty.

Background: The main reasons for revision of unicompartmental knee arthroplasty (UKA) are loosening, wear, extension of osteoarthritis to another compartment, and infection. There have been no studies of the management of infected UKA, whose incidence varies from 0.2% to 1%.

One-stage exchange arthroplasty for chronic periprosthetic hip infection: results of a large prospective cohort study.

Background: Exchange arthroplasty of one or two stages is required for the treatment of chronic periprosthetic joint infections. Two-stage exchange is costly and has high morbidity with limited patient mobility between procedures. One-stage exchange has been promoted by several European teams as the preferred alternative.

Campylobacter infection after prosthetic joint surgery.

Few cases of Campylobacter prosthetic joint infection (PJI) have been reported so far. We describe the demographic characteristics, underlying conditions, clinical features, treatment, and outcome of 8 patients with Campylobacter PJI in our hospital. All strains were confirmed at the French National Reference Center for Campylobacter and Helicobacter.

Continuous high-dose vancomycin combination therapy for methicillin-resistant staphylococcal prosthetic hip infection: a prospective cohort study.

Few data are available on treatment and outcome of methicillin-resistant (MR) staphylococcal prosthetic joint infections. Vancomycin remains the treatment of choice for these infections, but its efficacy and safety in bone-and-joint infections are insufficiently documented. We conducted a prospective cohort study on 60 patients treated between November 2002 and December 2008 for chronic MR staphylococcal (44 S.

Infected total hip arthroplasty revision: one- or two-stage procedure?

Introduction: Better outcomes have been reported for two-stage total hip arthroplasty (THA) revision for infection. However, one-stage revision arthroplasty remains an attractive alternative option since it requires only one operation. A decision tree has been developed by the authors in order to determine which type of surgical procedure can be performed safely.

Monitoring the one year postoperative infection rate after primary total hip replacement.

Purpose: Infection of a total hip replacement is potentially a devastating complication. Statistical process control methods have been generating interest as a means of improving the quality of healthcare, and we report our experience with the implementation of such a method to monitor the one year infection rate after primary total hip replacement.

Method: Infection was defined as the growth of the same organism in cultures of at least two aspirates or intra-operative specimens, or growth of one pathogen in a patient with local signs of infection such as erythema, abscess or draining sinus tract.

Infected total hip arthroplasty treated by an irrigation-debridement/component retention protocol. A prospective study in a 12-case series with minimum 2 years' follow-up.

Introduction: Treatment of infection after total hip replacement (THR) is complex and costly. Debridement with component retention is an attractive solution. Success rates in the literature vary widely (18-90%) according to patient selection criteria.

Arthroplasty following a septic arthritis history: a 53 cases series.

Introduction: The most feared complication of arthroplasty after septic arthritis (active or quiescent) on a degenerative joint is septic failure, but this risk is difficult to assess. The aim of the present study was to analyze the results of arthroplasties after septic arthritis of native knee and hip joints, in terms of functional results and infection control and to seek eventual risk factors of failure.

Patients And Methods: Fifty-three cases of septic arthritis treated by arthroplasty (31 knees and 22 hips) were retrospectively included.
