Extra-Articular Tenodesis in Combination with Anterior Cruciate Ligament Reconstruction: An Overview.

Anterior cruciate ligament (ACL) reconstruction is a successful procedure with high rates of return to sport. However, some patients experience persistent instability and graft failure. These adverse events have a significant impact, especially on high-level athletes.

No influence of obesity on survival of cementless, posterior-stabilised, rotating-platform implants.

Introduction: This study compares survival and outcomes in four total knee arthroplasty (TKA) populations defined by baseline body mass index (BMI). We hypothesised that there would be no difference in survival between the groups.

Materials And Methods: Using an initial cohort of 1059 TKAs, BMI was systematically measured prior to surgery.

Arthroscopically assisted fixation is a reliable option for patellar fractures: A literature review.

Unlabelled: Proper reduction and stable fixation of articular fractures is essential for an early recovery and to avoid late complications. Arthroscopically assisted techniques for minimally invasive fixation have been introduced to reduce local morbidity and improve anatomic reduction of the fragments. However up to date no clear indications for surgery have been given.

Coronal alignment after total knee arthroplasty.

Recent studies have challenged the long-held notion that neutral mechanical alignment after total knee arthroplasty leads to optimal function and survivorship.The ideal alignment for function and survivorship may actually be different.Kinematic alignment, where components are implanted to re-create the natural flexion/extension axis of the knee, may lead to improved functional results.

Does low-constraint mobile bearing knee prosthesis give satisfactory results for severe coronal deformities? A five to twelve year follow up study.

Purpose: Severe varus and valgus knee deformities traditionally are replaced with constrained implants, with a number of disadvantages. We present our results in this challenging group using a low constraint deep-dish mobile bearing implant design.

Methods: One hundred fifty-four patients (170 arthroplasties) who underwent primary TKA using a deep-dish, mobile bearing posterior-stabilized implant for severe varus (HKA < 170°) or valgus (HKA > 190°) deformity between 2004 and 2009 were evaluated at a mean of 6.

Ramp lesions in ACL deficient knees in children and adolescent population: a high prevalence confirmed in intercondylar and posteromedial exploration.

Purpose: Ramp lesions are common in ACL deficient knees. Their diagnosis is difficult and, therefore, they may be underestimated. So far, no study analyzed their prevalence in a pediatric population.

Total knee arthroplasty after varus distal femoral osteotomy vs native knee: similar results in a case control study.

Purpose: The aim of this study was to investigate the results of total knee arthroplasty (TKA) performed after varus distal femoral osteotomy (VrDFO), in comparison to a control group of TKAs performed as the primary intervention for arthrosis. Main hypothesis was that the medium term results for the two groups would be similar.

Methods: All TKAs performed after VrDFO were extracted from a single centre, prospective database of 4046 arthroplasties.

Proximal tibial bony and meniscal slopes are higher in ACL injured subjects than controls: a comparative MRI study.

Purpose: Increased tibial slope is reported as a risk factor of non-contact anterior cruciate ligament (ACL) injury, but the effect of the soft tissues on slope remains unclear. The primary aims of this study were to compare the tibial bony and soft tissue slopes between patients with and without ACL injury, and to investigate the relationship between the meniscal slopes (MS) and the tibial bony slope. Our hypothesis was that the menisci would correct the inclination of the bony tibial slope towards the horizontal.

Does a third condyle TKA restore normal gait kinematics in varus knees? In vivo knee kinematic analysis.

Introduction: Patients with knee osteoarthritis tend to modify spatial and temporal parameters during walking to reduce the pain. Total knee arthroplasty (TKA) is considered the gold standard treatment for end-stage knee osteoarthritis. However, reduced physical function of the knee is partly, but apparently not fully, remedied by surgery.

The evolution of outcomes and indications for the dual-mobility cup: a systematic review.

Purpose: Instability following total hip arthroplasty remains a common and disabling complication. The dual mobility cup (DMC) allows a reduction in the dislocation rate. An increasing number of studies have been undertaken to better understand DMC long term outcomes and complications.

Total hip arthroplasty using direct anterior approach and dual mobility cup: safe and efficient strategy against post-operative dislocation.

Aim: We hypothesize that a dual mobility cup can be safely used via the direct anterior approach, without increasing the risk of complications or incorrect positioning.

Materials And Methods: This retrospective study compared 201 primary total hip arthroplasties using a dual mobility cup performed via direct anterior approach without a traction table, to 101 arthroplasties performed via posterolateral approach. Implant positioning, function scores, and early complications were recorded.

Total knee implant posterior stabilised by a third condyle: Design evolution and post-operative complications.

Background: Despite excellent long-term outcomes, posterior stabilisation by a third condyle continues to receive unwarranted criticism regarding patellar complications and instability.

Hypothesis: Complication rates with a tri-condylar posterior-stabilised implant are similar to those with other posterior-stabilised prostheses and have diminished over time due to improvements in prosthesis design.

Material And Methods: Post-operative complications and revision rates were assessed retrospectively in a prospective cohort of 4189 consecutive patients who had primary total knee arthroplasty (TKA) using a tri-condylar posterior-stabilised implant (Wright-Tornier) and were then followed-up for at least 24 months.

The role of patelloplasty in total knee arthroplasty.

Introduction: Anterior knee pain (AKP) is a frequent complication after total knee arthroplasty (TKA). Patelloplasty, defined as reshaping the patella for optimal tracking in the trochlea, has been proposed to reduce the rate of this complication in patellar retaining implants. Aim of this study was to analyze the available literature regarding the outcomes of patelloplasty and to assess its methodological quality.

The role of wound closure in total knee arthroplasty: a systematic review on knee position.

Purpose: Post-operative range of motion (ROM) is one of the most important parameters to assess, following total knee arthroplasty (TKA). The aims of the present systematic review were to analyse the available literature and determine if closing the knee in flexion or extension influences post-operative ROM, clinical outcomes, and complications following TKA.

Methods: A systematic review was performed using the keywords "total knee arthroplasty", "total knee replacement", and "wound closure" or "joint closure" or "extension" or "flexion" with no limit regarding the year of publication.

The role of high tibial osteotomy in the treatment of knee laxity: a comprehensive review.

Purpose: The purpose of this study is to review the indications for and outcomes of high tibial osteotomy in the treatment of patients with chronic knee laxity.

Methods: A comprehensive literature review was performed to identify surgical indications and results of high tibial osteotomy for the treatment of chronic knee laxity.

Results: Four distinct situations were identified in which a high tibial osteotomy may be advantageous: (1) anterior laxity with varus osteoarthritis, (2) chronic anterior laxity in the setting of varus with lateral ligamentous laxity, (3) chronic anterior laxity in the setting of a high tibial slope, and (4) chronic posterior laxity or posterolateral corner injury.

Equivalent results of medial and lateral parapatellar approach for total knee arthroplasty in mild valgus deformities.

Purpose: When performing total knee arthroplasty (TKA) in valgus knee deformities, a medial or lateral parapatellar approach can be performed, but the lateral approach is often considered technically more difficult. The purpose of this study was to compare intra-operative, early clinical and radiological outcomes of medial and lateral parapatellar approaches for TKA in the setting of moderate knee valgus (<10°).

Methods: We prospectively analysed 424 knees with pre-operative valgus deformity between 3° and 10° that underwent TKA over an 18-year period; 109 were treated with a medial approach and 315 with a lateral approach.

Lateral tibial plateau autograft in revision surgery for failed medial unicompartmental knee arthroplasty.

Purpose: Revision surgery for failed unicompartmental knee arthroplasty (UKA) with bone loss is challenging. Several options are available including cement augmentation, metal augmentation, and bone grafting. The aim of the present study was to describe a surgical technique for lateral tibial plateau autografting and report mid-term outcomes.

Posteromedial meniscal tears may be missed during anterior cruciate ligament reconstruction.

Purpose: This study aimed to assess the benefit of using an arthroscopic intercondylar view and a posterior medial viewing portal during anterior cruciate ligament (ACL) reconstruction in the diagnosis of posterior horn of the medial meniscus (PHMM) tears. A secondary objective was to determine clinical and radiological risk factors for the PHMM.

Methods: Forty-one patients undergoing isolated ACL reconstruction were prospectively evaluated.

Progression of medial osteoarthritis and long term results of lateral unicompartmental arthroplasty: 10 to 18 year follow-up of 54 consecutive implants.

Introduction: The literature results of unicompartmental knee arthroplasty (UKA) for isolated lateral osteoarthritis (OA) are not as good as for isolated medial OA. In 1988 our department started using a UKA with a fixed, all polyethylene tibial component and a resurfacing femoral component. The aim of this retrospective study is to report on the progression of medial OA and the long term results of this prosthesis implanted for isolated lateral OA, at a minimum follow up of ten years.

Medial retinaculum reefing for the treatment for patellar instability.

Purpose: Medial structures repair is a well-established approach in the treatment for patellar instability. However, the literature is confusing concerning the indications for surgery, the different surgical techniques and outcomes. The goal of this systematic review was to clarify the indications for medial structures repair and to analyse the results of both arthroscopic and open techniques.

Gait changes of the ACL-deficient knee 3D kinematic assessment.

Purpose: Static, one-dimensional testing cannot predict the behaviour of the anterior cruciate ligament (ACL)-deficient knee under realistic loading conditions. Currently, the most widely accepted method for assessing joint movement patterns is gait analysis. The purpose of the study was in vivo evaluation of the behaviour of the anterior cruciate ligament-deficient (ACLD) knees during walking, using 3D, real-time assessment tool.

In vivo assessment of weight-bearing knee flexion reveals compartment-specific alterations in meniscal slope.

Purpose: The purpose of this study was to determine the effects of flexion angle on meniscal slope during partial weight-bearing knee flexion.

Methods: Forty-eight sagittal sequences were performed on 12 patients (6 male patients, 6 female patients; 25.7 ± 10.

Dislocation and bicruciate lesions of the knee: epidemiology and acute stage assessment in a prospective series.

Introduction: Knee dislocation and bicruciate lesions are rare. Assessments of results from retrospective series carry an insufficient level of evidence. A prospective multicenter study was therefore set up, under the auspices of the French Society of Orthopedic Surgery.
