No difference in 13-year survival after medial pivot or central pivot mobile bearing total knee arthroplasty. A propensity matched comparative analysis.

Purpose: The present study was designed to evaluate the long-term results (more than 10 years) of mobile bearing total knee arthroplasty (TKA) and to compare the survival of medial pivot axis (MPA) and central pivot axis (CPA) TKAs. The primary hypothesis was that the 10- to 15-year survival rate of MPA TKAs will be better than CPA TKAs.

Methods: A national, multicenter, retrospective study was performed in France.

Talar Dislocation: Is Reimplantation a Safe Procedure?

Total or complete dislocation of the talus is a triple dislocation of the tibiotalar, talocalcaneal, and talonavicular joints. It is a rare injury and is considered to be 1 of the most disabling ankle injuries. In light of the literature, there is a lack of consensus on their surgical treatment.

Navigation Improves the Survival Rate of Mobile-Bearing Total Knee Arthroplasty by Severe Preoperative Coronal Deformity: A Propensity Matched Case-Control Comparative Study.

The primary hypothesis of this study was that the survival rate over 10 years of total knee arthroplasties (TKAs) implanted with a navigation system was superior to that of TKAs implanted with a conventional technique. The secondary hypothesis was that the severity of the initial coronal deformity had a negative influence on the survival rate. A national, multicentric, retrospective study was performed in France, including eight university or private centers with high volumes in knee surgery.

Inconsistent relationship between body weight/body mass index prior to total knee arthroplasty and the 12-year survival.

Background: The primary hypothesis was that body weight (BW) and body mass index (BMI) significantly impact the long-term survival rate after implantation of a mobile bearing total knee arthroplasty (TKA).

Methods: A national, multicentric, retrospective study was performed in France. A total of 1604 TKAs were included.

Periprosthetic joint infection in aseptic total hip arthroplasty revision.

Purpose: There is no consensus regarding systematic screening for infection in aseptic revision total hip arthroplasty (THA). The rationale for systematic intra-operative samples is to increase the sensitivity of latent infections detection, which may require specific treatment. However, the incidence of occult infection in revision THAs is not precisely known.

Same-stage total knee arthroplasty and osteotomy for osteoarthritis with extra-articular deformity. Part I: Tibial osteotomy, prospective study of 26 cases.

Background: In patients with advanced knee osteoarthritis and extra-articular knee deformity (EKD), ligament balance may be difficult to achieve during total knee arthroplasty (TKA). Treatment options include two-stage surgery with the first stage involving correction of the EKD and same-stage TKA and tibial osteotomy (1S-TKA-TO). The objective of this study was to assess outcomes in 26 patients managed with 1S-TKA-TO.

Use of morselized allografts for acetabular reconstruction during THA revision: French multicenter study of 508 cases with 8 years' average follow-up.

Background: In the context of acetabular reconstruction, bone defects can be filled with processed or unprocessed bone allografts. Published data are often contradictory on this topic and few studies have been done comparing processed allografts to fresh-frozen ones. This led us to conduct a large study to measure the factors impacting the survival of THA revision: (1) type of allograft and cup, (2) technical factors or patient-related factors.

Posterior drawer after olecranization of the patella in posterior cruciate-injured knees: A cadaver study.

Introduction: Olecranization of the patella (OP) is a surgical technique that anchors the patella to the tibia using a Steinmann pin to reduce the posterior drawer in cases of acute posterior cruciate ligament (PCL) tears. The advantage of this procedure is that rehabilitation can start early with passive and active mobilization, all the while maintaining the reduced position. The primary objective of this cadaver study was to evaluate the reduction in the posterior drawer induced by OP.

Pyoderma gangrenosum after orthopaedic or traumatologic surgery: a systematic revue of the literature.

Introduction: Pyoderma gangrenosum (PG) is a neutrophilic dermatosis characterised by a painful ulceration mimicking infection of the operative site. To this day, there is still no general agreement on the medical and surgical treatment of PG. This systematic review of the literature aims to summarise recent studies about post-operative PG in orthopaedic surgery to improve its medical and surgical management.

Distraction-free ankle arthroscopy for anterolateral impingement.

The origin of chronic pain after external ankle sprain is better known with arthroscopy's contribution. Chronic hypertrophic synovitis of the anterolateral ankle region is seemingly the cause, resulting in "anterolateral ankle impingement." But is partial synovectomy with fibrosis resection under arthroscopy always possible without any distraction? Are results affected? This retrospective study concerned only patients with soft tissue ankle impingement.

Comparative study of femoral diaphyseal morphometry in two male populations, in France and a French West Indies island: an example of clinical relevance of comparative anatomy for orthopedic practice.

Our aim, through a comparative study of two populations, one European and the other Afro-Caribbean, was to find out whether there were differences in radiographic measurements of femoral diaphyseal canal diameter, thickness of the medial and lateral cortex, and global diaphyseal diameter. We studied the nailed femurs of adult males in a population of 54 Europeans and 52 Afro-Caribbeans. Both populations were comparable in terms of age, height and weight.

Percutaneous suture of acute Achilles tendon rupture. A study of 60 cases.

Conservative treatment of Achilles tendon ruptures may lead to re-rupture. Open surgical repair entails a risk of skin necrosis or infection. Several percutaneous techniques have been used, such as Tenolig or Achillon, but these techniques are costly and may be marred by wound healing problems.

Hip subluxation associated with Pipkin II fracture: an injury to look for before reduction.

Fractures of the femoral head are rare. They usually occur in association with a posterior hip dislocation secondary to a high-energy trauma (motor vehicle accident). We report a case of Pipkin II fracture associated with an irreducible hip subluxation.

The level of the joint line after cruciate-retaining total knee replacement: a new coordinate system.

This study assessed joint line changes after knee replacement surgery. Sixty consecutive cruciate-retaining total knee replacements were followed up. The height of the femorotibial joint line in extension and in 90 degrees flexion were analysed.

Infantile Blount's disease treated by hemiplateau elevation and epiphyseal distraction using a specific external fixator: preliminary report.

The treatment of infantile Blount's disease remains controversial. The progressive development of epiphysiodesis of the medial tibial physis induced a complex deformity of the lower limb such as severe genu varum, joint incongruity, torsion instability and leg length discrepancy with major functional consequences. Nine knees on eight children (average age was 7 years and 2 months) were treated by a one-time procedure using a specific external fixator that combined elevation of the medial tibial plateau, axial correction in the valgus, complete sterilization of the upper tibial growth cartilage, leg lengthening anticipation and de-rotation if necessary.

Traumatic femoral bone defect reconstruction with an autoclaved autologous femoral segment. A 10-year follow-up.

Traumatic bone defects in the diaphyso-metaphyseal distal part of the femur are difficult to treat. Only two publications have described traumatic extrusion of a femoral shaft fragment and its successful replacement after autoclave sterilisation. We report the case of a 17-year-old patient who had traumatic extrusion of an 11- cm segment of his distal femur.
