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.

Archetype analysis of the spine-hip relationship identifies distinct spinopelvic profiles.

Introduction: The position of the pelvis in the sagittal plane can vary considerably between different functional positions. Adapting the position of the acetabular cup in relation to the alignment between the spine and the hip of each individual, prior to prosthesis placement, can prevent the risk of prosthetic impingement. Taken individually, risk factors for unfavorable spinopelvic kinematics can be difficult to interpret when trying to precisely predict which patients are at risk.

Managing early complications in total hip arthroplasty: the safety of immediate revision.

Purpose: Immediate revision refers to a reoperation that involves resetting, draping, and exchanging the implant, after wound closure in total hip arthroplasty. The purpose of this study is to investigate the impact of immediate revision after total hip arthroplasty on subsequent infection and complication rates.

Methods: A total of 14,076 primary total hip arthroplasties performed between 2010 and 2020 were identified in our institutional database, of which 42 underwent immediate revision.

Cross-cultural adaptation and reliability of the Foot Posture Index (FPI-6) - French version.

Purpose: The 6-item Foot Posture Index (FPI-6) is a reliable tool for the evaluation of foot deformities. Our aim was to translate and cross-culturally validate the FPI-6 for use in French-speaking countries and to determine the intra-rater and inter-rater reliability of the French version.

Methods: Cross-cultural adaptation was performed according to guidelines.

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.

Development of a preoperative questionnaire to improve satisfaction with hallux valgus repair: A Delphi study.

Background: Satisfaction with hallux valgus repair is often poor, despite good surgical outcomes. Many tools have been developed to assess the outcome of the procedure; however none evaluate the association between the initial motive for repair and the reasons for post-surgical dissatisfaction. The aim of this study was to develop a new tool to analyse the subjective and objective expectations of individuals during a pre-operative consultation for hallux valgus repair in order to improve post-surgical satisfaction.

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.

A Systematic Review on Selected Complications of Open-Wedge High Tibial Osteotomy from Clinical and Biomechanical Perspectives.

Background: The wedge opened during high tibial osteotomy defines the alignment correction in different body planes and alters soft tissue insertions. Although multiple complications of the surgery can be correlated to this, there is still a lack of consensus on the occurrence of those complications and their cause. The current study is aimed at clarifying this problem using a combined medical and biomechanical perspective.

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.

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.

A new "tension side" locking plate for Hallux Valgus: A prospective multicentre case series.

Background: Proximal osteotomy of the first metatarsal is often indicated for Hallux Valgus correction. Previously recognised complications however, include transfer metatarsalgia, first metatarsophalangeal joint stiffness, problems with fixation and prominence of metalware.

Methods: We report on one year follow up of an international prospective series between June 2009 and October 2012 involving three centres, including 91 feet (58 patients) that underwent proximal osteotomy, using a new locking plate applied to the plantar surface of the metatarsal.

Patient's satisfaction after outpatient forefoot surgery: Study of 619 cases.

Introduction: The number of outpatient surgical procedures performed in France on the forefoot has grown rapidly in recent years.

Objectives: The goal of this study was to evaluate experience and satisfaction of patients undergoing outpatient foot surgery using a telephone questionnaire developed for this purpose.

Material And Methods: In 2012 and 2013, every patient who was admitted to the day surgery unit at our hospital for an open procedure on their forefoot was called the morning after the procedure.

Flexor digitorum brevis tendon transfer to the flexor digitorum longus tendon according to Valtin in posttraumatic flexible claw toe deformity due to extrinsic toe flexor shortening.

Claw toe deformity after posterior leg compartment syndrome is rare but incapacitating. When the mechanism is flexor digitorum longus (FDL) shortening due to ischemic contracture of the muscle after posterior leg syndrome, a good treatment option is the Valtin procedure in which the flexor digitorum brevis (FDB) is transferred to the FDL after FDL tenotomy. The Valtin procedure reduces the deformity by lengthening and reactivating the FDL.

Influence of socioprofessional category on the duration of sick leave after hallux surgery: a prospective study of 102 cases.

Introduction: Surgery of the forefoot including the hallux involves procedures on one bone or more. Usually bone union occurs within 45 days after surgery. During convalescence, the patient can gradually return to his/her activities.

Doctor, what does my knee arthroplasty weigh?

The aim of this study was to compare the weight of the total knee arthroplasty (TKA) implants and the weight of the natural knee. A prospective study was conducted with two different brands of cemented primary TKA. During the procedure, we collected the removed bone, soft tissues and the post-implantation cement and weighed them all separately at the end.

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.

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.

Arthrodesis with internal fixation of the infected ankle.

Arthrodesis may be necessary to avoid amputation when treating an infected tibiotalar joint. In such cases, external or hybrid fixation is usually used. In this retrospective study, we report our experience in treating tibiotalar joint infection by arthrodesis with internal fixation.
