Acute injury of the articular cartilage and subchondral bone: a common but unrecognized lesion in the immature knee.

摘要: OBJECTIVE. We studied the prevalence of injuries articular cartilage and subchondral bone after acute trauma in skeletally immature knees using high-resolution MRI.MATERIALS AND METHODS. reviewed knee MRIs 126 young children adolescents suspected to have internal derangement, including 82 with open physes a control group 44 who were mature. High-resolution proton density T2-weighted pulse sequences used all patients. The common two groups was compared chi-square analysis. Levels interobserver agreement for evaluation chondral lesions determined kappa statistic.RESULTS. In group, most prevalent (prevalence = 0.34, p 0.009) followed by meniscal anterior cruciate ligament 0.23 0.24, respectively). No significant difference injury before ph...
