Biomechanical assessment of ligament maturation after arthroscopic ligament reconstruction of the anterior talofibular ligament.

Background: Many techniques have been described for lateral ankle ligament reconstruction. Although the biomechanical properties of gracilis tendons are different from those of ligaments, the use of a gracilis tendon autograft is a popular option for anatomical reconstruction. Graft maturation and the biomechanical processes over time remain unclear.

Total knee arthroplasty in patient with poliomyelitis sequelae: maintaining a recurvatum is associated with better mid-term functional results.

Purpose: Total knee arthroplasty (TKA) in patients with sequelae of poliomyelitis is a surgical challenge due to muscle weakness, bone deformities or post-polio syndrome (PPS). Few data exist to determine the factors contributing to poor functional results. This study aimed: (1) to describe a cohort of patients with poliomyelitis sequelae who underwent TKA; (2) to examine risk factors for poor functional outcome.

MRI evaluation of ATFL and CFL ligamentization after anatomical surgical reconstruction with a hamstring graft.

Background: Chronic ankle instability is frequent complication following ankle sprains. Anatomical reconstruction of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) with a gracilis autograft is a validated reconstruction technique. The signal-to-noise quotient ankle (SNQA) score evaluates graft maturation with MRI and has been shown to be reproducible and reliable.

Anterior-approach total hip arthroplasty in patients with poliomyelitis: Long-term outcomes.

Objective: In patients with residual poliomyelitis-related impairments, total hip arthroplasty (THA) is challenging due to the high frequency of risk factors such as hip dysplasia, dislocation, muscle weakness, and fracture. The objective of this study was to assess the long-term functional and radiographic outcomes of anterior-approach THA with a ceramic-ceramic, dual-mobility, or constrained implant in patients with poliomyelitis sequelae.

Hypothesis: THA via the anterior approach with a ceramic-ceramic, dual-mobility, or constrained implant is a reliable technique that is not associated with excess risks of instability or aseptic loosening.

A tight anterosuperior intercondylar notch may increase the risk of cyclops syndrome after anterior cruciate ligament reconstruction using a quadruple semi-tendinosus short autograft.

Background: Cyclops syndrome is loss of terminal knee extension caused by a fibrous nodule developed in the anterior intercondylar notch. The many known risk factors include preoperative motion-range limitation, tibial tunnel malposition, and tight hamstrings. The primary objective of this study was to assess whether intercondylar notch size was associated with the risk of cyclops syndrome or graft tear after anterior cruciate ligament (ACL) reconstruction using a quadruple semi-tendinosis autograft.

Lumbosacral plexus and pudendal nerve magnetic resonance tractography: A systematic review of the clinical applications for pudendal neuralgia.

Diffusion tensor imaging (DTI) is commonly used to establish three-dimensional mapping of white-matter bundles in the supraspinal central nervous system. DTI has also been the subject of many studies on cranial and peripheral nerves. This non-invasive imaging technique enables virtual dissection of nerves in vivo and provides specific measurements of microstructural integrity.

Is there a femoral morphology at risk of a cervical or pertrochanteric fracture? Description and validation of the "Neck shaft ratio" and the "Intertrochanteric distal ratio" after analyzing a continuous cohort of 126 bilateral fractures of the proximal femur.

Background: Proximal femur fractures constitute a public health concern given their high frequency and the aging population. The frequency of a contralateral fracture occurring can reach up to 15% of cases. Certain historical or demographic factors constitute risk factors for refracture, but the type of fracture, either of the femoral neck (FN) or pertrochanteric (PT), cannot be predicted.

Methods: Between January 2005 and December 2017, all patients undergoing TAA revision at our hospital were included. Indications for revision, type of surgery performed, improvement in function assessed with the AOFAS score, occurrence of complications and implant survival at last follow-up were analyzed.

Diagnosis and management of METS-Stanmore Morse taper failure.

We describe clinical semiology in 6 cases of METS-Stanmore distal femoral Morse taper impaction failure: from obvious forms with intraprosthetic dislocation to chronic forms with less obvious symptoms: instability, piston sensation, rotational disorder in gait. The diagnostic procedure in chronic forms is described, notably with dynamic examination under fluoroscopy. Reduction and re-impaction by external maneuver can be attempted; in case of failure or of any suspicion of taper disassembly, the 2 modular implant components have to be replaced.

Femoral condyle bone mineral density in osteoarthritis differs significantly between knees with valgus vs. varus deformity.

Background: The objective of this study was to measure bone mineral density (BMD) of the cancellous bone in both femoral condyles and to compare the results according to the hip-knee-ankle (HKA) angle in patients with knee osteoarthritis.

Hypothesis: BMD of cancellous bone in the medial condyle is markedly lower in valgus knees compared to that in the lateral condyle in varus knees.

Methods: Consecutive patients with computed tomography (CT) of the knee and long-leg radiographs obtained in preparation for total knee arthroplasty were included.

Is lateral femoral condyle hypoplasia a feature of genu valgum? A morphological computed tomography study of 200 knees.

Background: Young surgeons are taught that genu valgum deformity is associated with hypoplasia of the lateral femoral condyle, despite the absence of supporting evidence. The objective of this study was to determine whether the lateral condyle was hypoplastic in genu valgum, by assessing the morphological features of the distal femur and their variations according to the severity of the coronal deformity.

Hypothesis: The lateral femoral condyle is not hypoplastic in genu valgum deformity.

Adaptation of the Signal Noise Quotient MRI classification for graft ligamentization analysis following ATFL and CFL anatomical reconstruction: Validation of the SNQA.

Background: Chronic ankle instability is the most frequent clinical sign of an antero tibiofibular (ATFL) and/or calcaneo fibular ligament (CFL) tear. One common surgical technique is to use the distal tendon of the gracilis muscle to reconstruct both the ATFL and CFL. In the knee, the hamstring tendons used in anterior cruciate ligament (ACL) reconstruction may go through structural modifications called "ligamentization ".
