KOL-Index: 122 Background: Osteochondral allograft (OCA) transplantation has evolved into a first-line treatment for large chondral and osteochondral defects, aided by advancements in storage protocols and a growing body of clinical evidence supporting successful clinical outcomes and long-term survivorship. Despite the body of literature supporting OCAs, there still remains controversy and debate in the ...

KOL-Index: 35 BACKGROUND: Several systems have been proposed for classifying osteochondritis dissecans (OCD) of the knee during surgical evaluation. No single classification includes mutually exclusive categories that capture all of the salient features of stability, chondral fissuring, and fragment detachment. Furthermore, no study has assessed the reliability of these classification systems. PURPOSE: To ...

KOL-Index: 35 Background: Tibial spine fractures, although relatively rare, account for a substantial proportion of pediatric knee injuries with effusions and can have significant complications. Meyers and McKeever type II fractures are displaced anteriorly with an intact posterior hinge. Whether this subtype of pediatric tibial spine fracture should be treated operatively or nonoperatively remains ...

KOL-Index: 28 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. METHODS: Ten orthopedic sports surgeons rated the ...

KOL-Index: 26 OBJECTIVE: Juvenile osteochondritis dissecans (JOCD) is similar to osteochondrosis dissecans (OCD) in animals, which is the result of failure of the cartilage canal blood supply, ischemic chondronecrosis and delayed ossification, or osteochondrosis. The aim of the current study was to determine if osteochondrosis lesions occur at predilection sites for JOCD in children. METHOD: Computed ...
KOL-Index: 24 BACKGROUND: Osteochondritis dissecans (OCD) was first described to provide an explanation for the nontraumatic development of loose bodies within a joint. Despite many reports on the subject, there remains no clear understanding of the etiology, natural history, or treatment. QUESTIONS/PURPOSES: This review was undertaken to delineate (1) the etiology of OCD; (2) the presentation and ...

KOL-Index: 21 Objectives: Very few predictors of healing have been identified to help guide OCD treatment decisions for patients, families and physicians. As this condition is not common, multi-center study groups will be necessary to determine optimal diagnostic and treatment strategies. For staging systems to be useful, there must be agreement among observers of each stage, and from different centers. ...

KOL-Index: 20 BACKGROUND: Imaging characteristics of osteochondritis dissecans (OCD) lesions quantified by magnetic resonance imaging (MRI) are often used to inform treatment and prognosis. However, the interrater reliability of clinician-driven MRI-based assessment of OCD lesions is not well documented. PURPOSE: To determine the interrater reliability of several historical and novel MRI-derived ...

KOL-Index: 19 Although osteochondritis dissecans (OCD) has been a recognized condition for more than 100 years, our understanding of the etiology, natural history, and treatment remains poorly characterized. OCD most commonly affects the knee, followed by the elbow and ankle. Adolescents and young adults are most commonly affected. Patients present with vague, often intermittent symptoms and generally ...

KOL-Index: 19 BACKGROUND: The cognitive, behavioral, and emotional deficits that may be associated with sports-related concussions among adolescents are unclear. PURPOSE: To examine the association between reported concussion history and factors relating to cognitive, behavioral, and emotional health among a population-based sample of US high school-aged adolescents. STUDY DESIGN: Cross-sectional study; ...
