Antibiotic Prophylaxis in One-Stage Revision of Septic Total Knee Arthroplasty: A Scoping Review.

Background: Total knee replacement (TKA) is becoming a routine procedure in orthopedic surgery. One of the possible complications of this surgery is periprosthetic joint infection (PJI). The purpose of this study is to identify, through a literature review, which antibiotic is used as prophylaxis for septic one-stage revision TKA and what is the rationale for its use.

Return-to-sport criteria after isolated meniscus suture: Scoping review of the literature.

Background: Follow-up care including rehabilitation therapy after isolated meniscal repair remains to be standardized. Thus, no standard criteria are available for the return-to-running (RTR) or return-to-sport (RTS). The objective of this study was to identify criteria for RTR and RTS after isolated meniscal repair, based on a review of the literature.

Methods: The CARENFER PBM study was a prospective cross-sectional study in 46 centers specialized in orthopedic, cardiac, urologic/abdominal, or gynecological surgery.

After MPFL reconstruction, femoral tunnel widening and migration increase with poor tunnel positioning and are related to poor clinical outcomes.

Purpose: Isolated MPFL reconstruction (iMPFLR) is increasingly used for the surgical treatment of treatment for recurrent patella dislocation. The purpose of this study was to evaluate the influence of tunnel widening and migration on clinical outcomes after iMPFL using a CT-scannographic analysis at 6 months postoperatively.

Methods: One hundred and sixty patients (91 females for 69 males) with an average age of 23 years [14-54] who underwent iMPFLR and had an evaluation scan at 6 months postoperatively were evaluated with a mean follow-up of 97 ± 89 months [12 to 166].

Optimal Combination of Femoral Tunnel Orientation in Anterior Cruciate Ligament Reconstruction Using an Inside-out Femoral Technique Combined With an Anterolateral Extra-articular Reconstruction.

Background: The optimal orientation of the anterolateral extra-articular reconstruction (ALLR) femoral tunnel to avoid collision with the anterior cruciate ligament reconstruction (ACLR) femoral tunnel is not clearly defined in the literature.

Purpose: To define the optimal combination of orientations of the ALLR femoral tunnel and the ACLR femoral tunnel using an inside-out technique to minimize risk of collision between these tunnels.

Study Design: Descriptive laboratory study.

Survival and complications of total hip arthroplasty using third-generation dual-mobility cups with non-cross-linked polyethylene liners in patients younger than 55years.

Background: In younger patients, total hip prostheses are subjected to wide motion ranges and wear-inducing forces. Dual-mobility cups (DMCs) are effective in decreasing the risk of dislocation. However, wear and osteolysis have been reported with first-generation DMCs.

Background: Infections after anterior cruciate ligament reconstruction (ACLR) are rare. No cases of infection have been described to our knowledge.

Case Summary: We describe a rare case of infection in a 23-year-old patient following an ACLR.

The anatomy of Kaplan fibers.

Purpose: Kaplan fibers (KF) have been described as connections between the iliotibial band and the distal femur. They are divided into two distinct structures, proximal (PKF) and distal (DKF) fibers, which may participate in the control of the rotatory knee stability. Their anatomical characteristics have not been investigated completely, in particular with respect to reconstruction procedures.

Introduction: Microfracture (MFx) is a widely used technique in the treatment of articular cartilage defects of the knee. The objective of this study was to determine the prognostic factors of functional outcomes after MFx treatment of knee cartilage defects ≤ 4 cm2.

Materials And Methods: Forty-eight patients who were to be treated by MFx for knee cartilage defects ≤ 4 cm2 were prospectively included.

Dual mobility cups for total hip arthroplasty: tips and tricks.

Since its creation in 1974, the Dual Mobility Cup (DMC) has been gaining in popularity, especially in the past decade. This intensive use could lead to inappropriate use and consequently to an increased complication rate. Compliance with conceptual requirements and surgical techniques will prevent the occurrence of complications that can be wrongly attributed to implants.

Low Revision Rates at More Than 10 Years for Dual-Mobility Cups Cemented Into Cages in Complex Revision Total Hip Arthroplasty.

Background: Instability and aseptic loosening are the two main complications after revision total hip arthroplasty (rTHA). Dual-mobility (DM) cups were shown to counteract implant instability during rTHA. To our knowledge, no study evaluated the 10-year outcomes of rTHA using DM cups, cemented into a metal reinforcement ring, in cases of severe acetabular bone loss.

Outcomes of Augmented Dual Mobility Acetabular Cups.

Introduction: Total hip arthroplasty (THA) in patients with acetabular bone defects is associated with a high risk of dislocation and aseptic loosening. No studies to date have examined the use of uncemented and augmented dual mobility cups (DMC) in patients with acetabular defects. We hypothesized that the use of augmented DMC under these conditions would reduce the dislocation rate and lead to satisfactory bone integration in the medium term despite acetabular bone defects.

Clinical and Radiological Predictors of Functional Outcome After Isolated Medial Patellofemoral Ligament Reconstruction at Midterm Follow-up.

Background: Isolated medial patellofemoral ligament reconstruction (iMPFLR) is increasingly used for the surgical treatment of recurrent patellofemoral instability.

Purpose: The purpose of this study was to identify the clinical and radiological predictors that can significantly influence the functional outcomes after an iMPFLR.

Study Design: Case series; Level of evidence, 4.

Dual mobility cups in total hip arthroplasty after failed internal fixation of proximal femoral fractures.

Introduction: Performing total hip arthroplasty (THA) following failed internal fixation of proximal femur fractures is associated with an elevated risk of implant dislocation. We hypothesized that using a dual mobility (DM) cup will help to reduce the risk of postoperative instability in this specific context.

Material And Methods: This was a retrospective study of 33 consecutive patients who underwent DM THA following failed internal fixation of a proximal femur fracture.

Determining the change in length of the anterolateral ligament during knee motion: A three-dimensional optoelectronic analysis.

Background: The variation of the anterolateral ligament (ALL) length during knee motion is still unclear, and the knee position in which a reconstruction graft should be tensioned remains controversial. The objective of this study was to determine the variation of the ALL length during knee motion using a three-dimensional optoelectronic system.

Methods: Kinematic analyses of 20 cadaveric knees were performed using a Motion Analysis® system.

Dual mobility acetabular cups for total hip arthroplasty: advantages and drawbacks.

Introduction: The dual mobility cup (DMC) concept was proposed by Professor Gilles Bousquet in 1974. Its' aims were to prevent postoperative dislocation, restore the physiological range of motion of the hip, and reduce the stresses at the interface. Since it was created, this design has been modified multiple times to reduce the complication rate, improve implant survival, and expand the indications.

Medial patellofemoral ligament reconstruction with or without tibial tubercle transfer is an effective treatment for patellofemoral instability.

Purpose: The hypotheses were that medial patellofemoral ligament reconstruction (MPFLr) would improve the long-term symptoms of patellofemoral Instability (PFI) and control patellar tilt, based on computed tomography (CT), and that the addition of a TT transfer, when it is necessary, would not deteriorate the outcome. The purpose of this study was to evaluate the long-term clinical and radiographic outcomes of a large series of MPFLr, either isolated or associated with a TT transfer.

Methods: From 133 MPFLr with a minimum of 4 years postoperatively, three groups were defined: isolated MPFLr, MPFLr with tibial tubercle (TT) medialisation or MPFLr with TT medialisation and distalisation.

Correction to: Intraprosthetic dislocation of dual mobility total hip arthroplasty: still occurring?

The published online version contains mistake in the author list for the author name "Di Iorio Alexandre" was incorrectly presented.

Intraprosthetic dislocation of dual mobility total hip arthroplasty: still occurring?

Purpose: The objective was to identify predictive factors for intraprosthetic dislocation (IPD) and to understand how improvements in dual mobility cups (DMC) have helped to reduce dramatically the occurrence of this complication.

Methods: DM mobile inserts retrieved from 93 hips were divided into three groups: first-generation DMC with IPD ("firstDMC-IPD"), first-generation DMC with over 15 years of implantation without IPD ("firstDMC-noIPD"), and latest-generation DMC ("newDMC"). The predictive factors for IPD based on clinical, prosthetic, radiological and intraoperative characteristics were analysed by multivariate analysis.

Anterolateral Ligament of the Knee: What we Know About its Anatomy, Histology, Biomechanical Properties and Function.

To better control anterolateral rotational instability (ALRI) after anterior cruciate ligament reconstruction (ACLR), many recent studies have examined the anterolateral ligament (ALL). Although some inconsistencies have been reported, anatomic studies demonstrated that the ALL runs on the lateral side of the knee from the femoral lateral epicondyle area to the proximal tibia, between Gerdy's tubercle and the fibula head. Histologic research has characterized the ALL structure, which is more than a simple capsular thickening; it shows a dense collagen core, typical bony insertions and mechanoreceptor function.

Ten-Year Clinical and Radiological Outcomes of 100 Total Hip Arthroplasty Cases with a Modern Cementless Dual Mobility Cup.

Introduction: The original cementless Sunfit® dual mobility cup (SERF, Décines, France) exhibited limited osseointegration due to its hydroxyapatite and alumina coating. We hypothesized that replacement of the alumina with plasma-sprayed titanium + hydroxyapatite and improvement of the external geometry (Sunfit TH®) would not increase the risk of aseptic loosening. The primary goal of this study was to determine the survivorship and clinical and radiological outcomes among patients with the Sunfit TH® implant.

The anterolateral ligament is a distinct ligamentous structure: A histological explanation.

Background: The aim was to determine whether the anterolateral ligament (ALL) had a histological structure that defined it as a real ligament.

Methods: Histological examination of 30 ALL samples taken from fresh-frozen knees were performed. The ALL femoral insertion and its relationship with the lateral collateral ligament (LCL) were studied and the tibial insertion and its relationship with articular cartilage of the tibial joint surface were analyzed.
