BACKGROUND Neointimal development is seen clinically after both vein grafting and balloon catheterization, but may not represent the same pathology under these 2 conditions. This study compared the degree of neointimal hyperplasia after vein grafting or arterial-injury grafts in 2 strains of mice: C57Bl/6 and FVB. METHODS AND RESULTS Jugular vein branches were interpositioned as grafts in the...

PURPOSE Autologous iliac crest bone grafting is an integral part of many orthopaedic surgical procedures. Several studies have documented morbidity and prolonged pain following iliac crest bone graft harvesting in adults; however, in children there is a paucity of information. The purpose of the present study was to quantify the degree of pain and morbidity associated with anterior iliac crest ...

Background: Rupture of the anterior cruciate ligament (ACL) is one of the most common injuries in patients referred to the emergency and orthopedic clinics. Reconstruction of the anterior cruciate ligament (ACLR) is one of the knee surgery methods used nowadays. Objectives: This study aimed to compare the results of the ACLR with the hamstring tendon using all-inside and outside-in techniques. ...

BACKGROUND Allograft healing (ligamentization) after reconstruction of the anterior cruciate ligament (ACL) is dependent on multiple factors, including tissue processing, host biologic environment, and biomechanical stressors. Magnetic resonance imaging (MRI) can be used to assess graft maturation after ACL reconstruction. HYPOTHESIS A significant difference will exist in the MRI analysis bet...

PURPOSE To investigate the usefulness of the "inducer grafting" technique for regeneration of the semitendinosus (ST) tendon after its harvest for anterior cruciate ligament (ACL) reconstruction. METHODS Twenty knees of 20 patients (mean age at the time of surgery, 23.1 years) underwent ACL reconstruction with a double bundle autograft using the ST tendon (7 patients) and the ST + the gracili...

BACKGROUND Press-fit fixation of patellar tendon-bone anterior cruciate ligament autografts is an interesting technique because no hardware is necessary. For hamstring tendon grafts, no biomechanical data exist of a press-fit procedure. HYPOTHESIS Press-fit femoral fixation of hamstring tendons is mechanically equivalent to press-fit patellar tendon-bone fixation. STUDY DESIGN Controlled la...
