BACKGROUND In sum, 1-, 2-, and 4-stranded allografts are used for soft tissue anterior cruciate ligament reconstruction; however, the fixation properties of fixation devices are not well assessed. HYPOTHESIS There are no differences in the biomechanical characteristics of 1 (Achilles)-, 2 (posterior tibialis)-, and 4 (semitendinosus)-stranded allograft tibial fixation. STUDY DESIGN Controll...

  Background: Ligament reconstruction is a common procedure in orthopedic surgery. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. Purposes: We sought to introduce our new technique of Bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (ACL) reconstruction and to compar...

Objective- To evaluate greater omentum as an autogenous free graft in enhancing bone healing.Design- Prospective descriptive trial.Animals- Ten mongrel adult dogs, 3 to 4 years old and weighing 25.2 to 31 kg, assigned into two equal experimental and control groups (5dogs/group), were used.Procedures- Mid-shaft osteotomy on right radius was followed by a partial omentectomy in all dogs. A 30x30 ...

Patients after anterior cruciate ligament (ACL) reconstruction surgery commonly encounters graft failure in the initial phase of rehabilitation. The inhibition of graft degradation is crucial for the successful reconstruction of the ACL. Here, we used biodegradable high-purity magnesium (HP Mg) screws in the rabbit model of ACL reconstruction with titanium (Ti) screws as a control and analyzed ...

Allograft safety is contingent on effective sterilization methods such as gamma irradiation. However, recent clinical studies have associated gamma irradiation with decreased graft strength and increased allograft failure rates, despite data that shows no deleterious effects to soft tissue biomechanics at gamma doses between 1.46 and 2.18 mRad. The objective of this study was to compare the bio...

OBJECTIVE To compare the biomechanical properties of cortical bone and surgical steel endoprosthesis for limb-sparing surgery of the distal radius in dogs and evaluate the role of the ulna in providing stability to the reconstructed limb. STUDY DESIGN Cadaveric biomechanical study. ANIMALS Twelve pairs of normal canine thoracic limbs. METHODS Paired limbs were divided into 4 groups: endop...

Introduction Controversy surrounds reconstruction of the anterior cruciate ligament (ACL) with regards to graft choice and fixation. Most surgeons performing ACL reconstruction use an intra-articular autogenous graft from either the patellar tendon or hamstrings. It has been suggested that hamstring tendon grafts are weaker than patellar tendon grafts, although there is conflicting data where m...

BACKGROUND Osteochondral autografts and allografts have been widely used in the treatment of isolated grade IV articular cartilage lesions of the knee. However, the authors are not aware of any study that has prospectively compared fresh osteochondral autografts to fresh allografts with regard to imaging, biomechanical testing, and histology. HYPOTHESIS The imaging, biomechanical properties, ...

BACKGROUND Graft-tunnel mismatch is a potential problem during single-incision technique for anterior cruciate ligament reconstruction with the central third of the patellar tendon. Mismatch is present when the graft is too long to fit appropriately in the tunnels that have been created. Graft rotation is one method for addressing this problem. PURPOSE To determine the results of graft rotati...
