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.

High sensitivity methods for automated rib fracture detection in pediatric radiographs.

Rib fractures are highly predictive of non-accidental trauma in children under 3 years old. Rib fracture detection in pediatric radiographs is challenging because fractures can be obliquely oriented to the imaging detector, obfuscated by other structures, incomplete, and non-displaced. Prior studies have shown up to two-thirds of rib fractures may be missed during initial interpretation.

The Reliability of Assessing Radiographic Healing of Osteochondritis Dissecans of the Knee.

Background: The reliability of assessing healing on plain radiographs has not been well-established for knee osteochondritis dissecans (OCD).

Purpose: To determine the inter- and intrarater reliability of specific radiographic criteria in judging healing of femoral condyle OCD.

Study Design: Cohort study (Diagnosis); Level of evidence, 3.
