A Simple Clinical Predictive Model for Arthroscopic Mobility of Osteochondritis Dissecans Lesions of the Knee.

Background: Osteochondritis dissecans (OCD) of the knee is a focal idiopathic alteration of subchondral bone and/or its precursor with risk for instability and disruption of adjacent cartilage. Treatment options focused on preventing premature osteoarthritis vary depending on multiple patient and lesion characteristics, including lesion mobility.

Purpose: To differentiate lesion mobility before arthroscopy using a multivariable model that includes patient demographic characteristics and physical examination findings.

MRI Features That Contribute to Decision-Making for Treatment of Capitellar OCD Lesions: An Expert Consensus Using the Delphi Method.

Background: Most healthcare providers utilize magnetic resonance imaging (MRI) to assist in diagnosing and treating osteochondritis dissecans (OCD) of the capitellum. However, consensus on imaging features that portend clinically relevant information in the care of these lesions has not been determined.

Purpose: To conduct a survey on the MRI features of a capitellar OCD that are salient for clinical decision-making using a classic Delphi protocol.

Lateral Patellar Inclination Angle Measured via a Two-Image Technique on Axial Magnetic Resonance Imaging.

Lateral patellar inclination (LPI) measures patellar tilt and is historically described on axial X-ray or a single magnetic resonance image (MRI). Given the variability in patellar height, LPI may be better represented by performing this measurement on two separate axial MRI images. We hypothesized that a two-image LPI measurement would be different from the current single-image LPI and have similar, if not superior reliability.

Demographics and Epidemiology of Discoid Menisci of the Knee: Analysis of a Large Regional Insurance Database.

Background: A discoid meniscus is a morphological variant of normal knee joint meniscus shape and ultrastructure that can lead to traumatic tearing of this tissue and early joint osteoarthritis.

Purpose/hypothesis: The purpose of this study was to determine the prevalence of discoid menisci in a large, ethnically diverse regional cohort and to evaluate possible risk factors. The hypothesis was that there would be no difference in the epidemiological distribution of discoid menisci based on ethnicity or sex.

Traumatic Patellar Dislocations in Childhood and Adolescents.

Patellar instability and associated patellar dislocation can result in significant pain, disability, and associated injuries in young athletes. The patellofemoral joint is a complex articulation with stabilizing restraints, both medially and laterally, that help guide the patella into the corresponding trochlear groove as the knee cycles through an extension-to-flexion arc. In addition to soft tissue injuries, many osseous aberrancies can contribute to patellar instability in young athletes, including trochlear dysplasia, patella alta, and axial and coronal plane abnormalities.

Paediatric proximal ACL tears managed with direct ACL repair is safe, effective and has excellent short-term outcomes.

Purpose: Anterior cruciate ligament (ACL) surgery in the paediatric population has long been a challenge. Non-operative treatment will result in persistent instability which can lead to chondral and meniscal injuries. The results of primary open ACL repair are poor.

Prospective Evaluation of a Treatment Protocol Based on Fracture Displacement for Pediatric Lateral Condyle Humerus Fractures: A Preliminary Study.

Background: To prospectively evaluate a displacement-based classification system and an outcome-derived algorithm in the treatment of children with lateral condyle fractures.

Methods: All children with a lateral condyle fracture were prospectively enrolled at our institution between 2013 and 2016. Fractures were classified and treated on the basis of the following classification system: type 1: <2 mm; treated with long arm casting, type II: 2 to 4 mm; treated with closed reduction and percutaneous pinning (CRPP), and type III: >4 mm; open reduction and percutaneous pinning (ORPP).

Pediatric and Adolescent Forearm Fractures: Current Controversies and Treatment Recommendations.

Pediatric and adolescent forearm fractures continue to present treatment challenges. Despite high-level evidence to the contrary, traditional guidelines for nonsurgical treatment have been challenged in favor of surgical intervention, but it is unclear if this results in improved outcomes. Recent evidence suggests that certain open fractures in children may be successfully treated nonsurgically.

Evidence-based review: management of open pediatric fractures.

Open fractures in the pediatric population are rare. As such, recommendations for care based on high-level studies are scarce. Furthermore, most level I and II recommendations come from studies involving open fractures in adults.

Does using the medial or lateral humeral line improve reliability of Baumann angle measurement on plain x-ray? The effect of humeral length visualized on the x-ray.

Background: Baumann angle (BA) is a common measure of coronal plane alignment of the distal humerus. We hypothesize that the reliability of measuring BA would be improved by using the medial and lateral cortical margins of the humerus seen on plain x-ray, rather than the estimated central humeral line, which is the "standard" technique. Further, we analyze whether the amount of humerus visible on the film improves the reliability of the method.

The lateral capitellohumeral angle in normal children: mean, variation, and reliability in comparison to Baumann's angle.

Background: Angular deformity is the most common complication of supracondylar humerus fracture. Baumann's angle (BA) is an established radiographic measure of coronal plane deformity after this injury. Numerous radiographic methods have been used to assess sagittal plane deformity, however, the mean, variability, and reliability of these measures has not been established.
