Normal bone growth of the pediatric knee as well as normal variants of ossification result in different appearances that can be identified on imaging (radiography/MR imaging). Familiarity with these changes is important to avoid confusing normal growth with pathology. This article illustrates the main features related to normal bone growth (growth arrest lines, physeal changes, ossification centers within the epiphysis, hematopoietic marrow within the metaphysis) and physis disappearance (« FOPE »). Variants in femur (epiphyseal irregularities, subchondral anomalies of posterior condyles, periosteal desmoid), tibia (tibial tuberosity ossification), and patella (dorsal defect, bipartite patella, lower pole fragmentation) are also described.
小儿膝关节的正常骨骼生长以及骨化的正常变异会导致在影像学检查（X线摄影/MR成像）中呈现出不同的表现。熟悉这些变化对于避免将正常生长与病变相混淆很重要。本文阐述了与正常骨骼生长相关的主要特征（生长停滞线、骨骺变化、骨骺内的骨化中心、干骺端内的造血骨髓）以及骨骺消失（“FOPE”）。还描述了股骨（骨骺不规则、后髁软骨下异常、骨膜硬纤维瘤）、胫骨（胫骨结节骨化）和髌骨（背侧缺损、二分髌骨、下极碎裂）的变异情况。
