目的：探讨X线检查在胫骨结节骨软骨炎诊断中的价值。方法：回顾性分析52个（42例患者）胫骨结节骨软骨炎的膝关节X线摄影图像，观察胫骨结节骨及其周围软组织的改变。结果：所有患病的胫骨结节均示其邻近软组织肿胀，胫骨结节二次骨化中心异常改变有局部骨隆起10个、轮廓不规则8个、密度不均匀15个、碎裂状11个、前方见碎骨片4个和胫骨结节向前上方移位12个。结论：X线检查是诊断胫骨结节骨软骨炎有价值的方法。

Radiographic diagnosis of osteochondrosis of tibial tuberosity

Objective To assess the value of radiography in the diagnosis of osteochondrosis of tibial tuberosity. Methods Fifty-two knee radiographies of 42 patients with osteochondrosis of tibial tuberosity were retrospectively analyzed, and the changes of the soft tissue and bone were observed mainly. Results Swelling of the soft tissue near tibial tuberosity was found in all cases, promontory of tibial tuberosity was found in 10 cases, the outline of the secondary ossification center was irregular in 8 cases, the density of the secondary ossification center was increased nonhomogeneously in 8 cases, the secondary ossification center was smashed in 11 cases, chip was seen before tibial tuberosity in 4 cases, tibial tuberosity moved toward out-up in 12 cases. Conclusion Radiography is a valuable method for the diagnosis of osteochondrosis of tibial tuberosity.
