AbstractPurposeThe purpose of the study was to determine the change in the graft bending angles at the femoral and tibial tunnel aperture in single-bundle posterior cruciate ligament (PCL) reconstruction. It was hypothesized that different knee flexion and different tunnel directions may affect changes of the femoral and tibial graft bending angle.MethodsThe right knees of 12 male subjects were scanned with a high-resolution computed tomography scanner at 4 different knee flexion angles (0 °, 45°, 90° and 135°). To begin with, the 3D knee models were created and manipulated with the use of several modeling ...

ConclusionsIrrigation solutions played an important role on the survival and metabolism of chondrocytes following injury. Ringer's solution and Balance salt had less adverse effect on chondrocyte survival after mechanical or thermal injury and were much more beneficial to cartilage repair than saline.RésuméObjectifsL’objectif de cette étude était d’examiner l’influence de différentes solutions d’irrigation sur la viabilité et le métabolisme des chondrocytes après une lésion mécanique ou thermique, en offrant des solutions d’...

AbstractPurposeTo determine the association between femoral torsion and anterior cruciate ligament (ACL) rupture and determine the level of torsion using magnetic resonance imaging (MRI).MethodsThe medical records of patients who were diagnosed with ACL injury were reviewed retrospectively. This descriptive epidemiological study included 2344 patients. MRI scans were examined and patients with femur and knee MRI scans obtained at the same time were identified (ACL-deficient group). Twenty-eight of them had femur and knee MRI scans because of an incidental benign lesion in the distal femur. Patients who were diagnosed with ...

This study investigates the influence of tibial slope on the ATA and the size of the resected tibial surface.MethodsCT scans of 20 cadaver knees were orientated in a standardized coordinate system and used to determine the position of the centres of rotation of the medial and lateral tibial articular surfaces and, hence, of the ATA, after a virtual resection of 6  mm with 0°, 3.5°, 7° and 10° slope, respectively. Furthermore, at each slope, the radii of the medial and lateral tibial articular surfaces after resection were calculated.ResultsCompared to resection of 6  mm with 0° slope, a slope ...

ConclusionsThis study found an asymmetrical inclination between medial and lateral condyles. This may be related to the asymmetrical motion of the knee, which is known as medial pivot motion. This finding provides valuable morphological information and may be useful for implant designs for total knee arthroplasty.Level of evidenceIV.

With the desire to remain athletically competitive, many adolescent athletes with shoulder instability are turning to early surgical invention. But is surgical repair always necessary and are all Bankart lesions identical? Using 3-dimensional, frequency-selective, fat-suppressed gradient recalled echo magnetic resonance imaging (MRI) scans, the authors noted that the anterior glenoid rim secondary ossification center peaks at age 16 years in male patients but is only fused in 70% of male patients at age 17 years.

ConclusionsThe rate of union at 3 months after an arthroscopic Latarjet with double-button fixation was 64%, reaching 93% at 1  year. This procedure should be carefully indicated in case of tobacco use or instability without glenoid bone defect, especially when the shoulder is exposed to high-energy trauma in the early phase after surgery.
