Suspensory fi xation devices in anatomic anterior cruciate ligament (ACL) reconstruction commonly feature a button that rests on the cortex of the femur, and a loop that holds the graft in position until healing can occur. While this loop can be closed and fi xed in length, some contemporary designs feature a loop that is adjustable. The purpose of this study was to assess the displacement of t...

BACKGROUND Optimization of anterior cruciate ligament (ACL) fixation is desired to improve graft healing. New soft tissue cortical suspension devices for femoral tunnel fixation should be biomechanically evaluated. HYPOTHESIS All femoral fixation devices would prevent a clinically significant amount of displacement and support loads significantly larger than in situ forces experienced by the ...

The aim of this study is to compare three modes of femoral fixation, namely Aperfix, Rigidfix and Endobutton, in anterior cruciate ligament (ACL) reconstruction. 120 patients were randomly assigned to three groups, each consisting of 40 patients, and each group was treated by one of the above mentioned methods of femoral fixation. All patients were examined prior to and 24 months after surgery,...

The initial strength of the intact medial collateral ligament (MCL) of the elbow and the strength of 4 reconstruction techniques were compared. Twenty cadaveric upper extremities were mounted in a custom jig with the elbow at 90 degrees , and a pneumatic cyclic valgus loading protocol was used. The mean peak load to failure was 142.5+/-39.4 N for the intact ligaments and 53.0+/-9.5 N for the do...

Surgical reconstruction of the anterior cruciate ligamentdeficient knee has become very common, with the majority of reconstructions performed using the semitendinosusgracilis tendon autograft construct or the central third bonepatellar tendon-bone autograft construct. Although generally uncommon, complications after anterior cruciate ligament reconstruction occur, and may include fractures of ...

Suture button-based femoral cortical suspension constructs of anterior cruciate ligament grafts can facilitate a fast and secure fixation. However, there are several case reports showing button malpositioning resulting from the inability to visualize the "flipped" button. Many current surgical techniques do not allow direct visualization of EndoButtons (Smith & Nephew, Andover, MA) in their fin...

Operative intervention is recommended for complete acromioclavicular (AC) joint dislocation to restore AC stability, but the best operative technique is still controversial. Twelve fresh-frozen male cadaveric shoulders (average age, 62.8 7.8 years) were equally divided into endobutton versus the modified Weaver-Dunn groups. Each potted scapula and clavicle was fixed in a custom made jig to allo...

We report the clinical and radiological outcomes of acromioclavicular (AC) joint reconstructive surgery using Arthrex Dog Bone Button FibertapeConstruct. 33 Patients were identified between April 2013 and April 2015 who had undergone AC joint repair using the Dog Bone double Endobutton for Rockwood Grade III-V injuries. Radiological follow up was made by measuring coracoclavicular distance (CCD...

A total of 218 patients with unilateral anterior cruciate ligament deficiency were randomly assigned to one of four groups. In group A an anatomical double bundle anterior cruciate ligament reconstruction was performed; group B were treated by a single bundle using an Endobutton for femoral fixation; in group C by a single bundle using RigidFix cross pins for femoral fixation; and in group D by...
