Effect of High-Protein Diets on Integrated Myofibrillar Protein Synthesis before Anterior Cruciate Ligament Reconstruction: A Randomized Controlled Pilot Study.

Increasing dietary protein intake during periods of muscle disuse may mitigate the resulting decline in muscle protein synthesis (MPS). The purpose of this randomized pilot study was to determine the effect of increased protein intake during periods of disuse before anterior cruciate ligament (ACL) reconstruction on myofibrillar protein synthesis (MyoPS), and proteolytic and myogenic gene expression. Six healthy, young males (30 ± 9 y) were randomized to consume a high-quality, optimal protein diet (OP; 1.

Posterolateral corner reconstruction of the knee: evaluation of a technique with clinical outcomes and stress radiography.

Background: Injuries to the posterolateral corner of the knee remain a challenging problem and have been cited frequently as a reason for failure of anterior and posterior cruciate ligament reconstructions. Although several reconstructive techniques currently exist, there are relatively few clinical outcomes data after reconstruction of the posterolateral corner.

Purpose: The study was undertaken to examine the clinical outcomes and provide objective data using arthrometry and stress radiography of a posterolateral corner reconstruction technique.

Acromioclavicular joint problems in athletes and new methods of management.

The acromioclavicular (AC) complex consists of bony and ligamentous structures that stabilize the upper extremity through the scapula to the axial skeleton. The AC joint pathology in the athlete is generally caused by 1 of 3 processes: trauma (fracture, AC joint separation, or dislocation); AC joint arthrosis (posttraumatic or idiopathic); or distal clavicle osteolysis. This article presents systematically the relevant anatomy, classification, evaluation, and treatment of these disorders.

Interference screw with Cortical button for distal biceps repair.

The management of distal biceps tendon ruptures has been the source of considerable research over the last decade. Many of the techniques used to secure tendon to bone have been applied to the distal biceps tendon. These include suture anchors, Cortical button, and more recently interference screw fixation.

Biomechanical and radiographic analysis of partial coracoclavicular ligament injuries.

Background: A spectrum of acromioclavicular joint injuries may exist between type II acromioclavicular joint disruption (coracoclavicular strain) and type III acromioclavicular joint injuries (coracoclavicular disruption). This may help explain the variability in outcomes seen in patients with type II acromioclavicular injuries.

Hypothesis: Injury to either the conoid or trapezoid ligaments would lead to instability of the acromioclavicular joint after complete acromioclavicular joint injury.

Anatomy of the clavicle and coracoid process for reconstruction of the coracoclavicular ligaments.

Background: Recently acromioclavicular joint reconstruction techniques have focused on anatomic restoration of the coracoclavicular (CC) ligaments. Such techniques involve creating bone tunnels in the distal clavicle and coracoid.

Purpose: To define the anatomy of the human clavicle and coracoid process of the scapula, in order to guide surgeons in reconstructing the CC ligaments.

A biomechanical evaluation of an anatomical coracoclavicular ligament reconstruction.

Background: Despite numerous surgical techniques described, there have been few studies evaluating the biomechanical performance of acromioclavicular joint reconstructions.

Purpose: To compare a newly developed anatomical coracoclavicular ligament reconstruction with a modified Weaver-Dunn procedure and a recently described arthroscopic method using ultrastrong nonabsorbable suture material.

Study Design: Controlled laboratory study.

Subpectoral biceps tenodesis with interference screw fixation.

The proximal portion of the long head of the biceps is a recognized cause of anterior shoulder pain. This article presents a novel technique for tenodesing the proximal biceps tendon. The tendon is evaluated and tenodesed in the same anatomic position beneath the pectoralis tendon, and is removed entirely from the bicipital groove.

Dopamine agonists suppress cholinomimetic-induced tremulous jaw movements in an animal model of Parkinsonism: tremorolytic effects of pergolide, ropinirole and CY 208-243.

Considerable evidence indicates that cholinomimetic-induced tremulous jaw movements in rats share many characteristics with human Parkinsonian tremor, and several antiparkinsonian drugs suppress cholinomimetic-induced tremulous jaw movements. The present study investigated three different types of dopamine agonists, which have known antiparkinsonian characteristics, for their ability to suppress the tremulous jaw movements induced by tacrine (5.0 mg/kg).
