Juvenile Osteochondritis Dissecans of the Knee: Perifocal Sclerotic Rim as a Prognostic Factor of Healing

Abstract

Prognostic study, Level II (retrospective study).

Novel Radiographic Feature Classification of Knee Osteochondritis Dissecans

“…27 The radiodensity of the rim of the parent bone adjacent to the OCD lesion was considered a measure of sclerosis in our study and demonstrated only fair to moderate reliability. Reliability may be improved by clarifying the question from ''what is the radiodensity of the rim of the parent bone'' to the more straightforward question of ''what is the sclerotic rim density.''…”

Paediatric Sports Injuries - Principles of Management

“…Initial treatment is with immobilization of the joint, with or without fixation or excision or large displaced fragments. Arthroscopy will allow direct visualization of the fragment, testing of stability and fixation, drilling or excision [44][45][46][47]. The long-term outcome is variable, but may, rarely, precipitate the end of competitive sport.…”

“…From these, assessment of size and stability will help guide management. Perifocal sclerosis is a negative prognostic indicator [45]. Initial treatment is with immobilization of the joint, with or without fixation or excision or large displaced fragments.…”

Whatʼs New in Pediatric Orthopaedics

“…Ramirez et al, in a recent review of eightyfive children and adolescents, demonstrated that the presence of a sclerotic rim around the lesion and older age correlated with a lower rate of spontaneous healing 23 . Fixation techniques used for stabilization of unstable juvenile osteochondritis dissecans lesions vary.…”
