Osteochondritis dissecans lesions occur frequently in children and adolescents. Treatment can be challenging and depends on the status of the articular cartilage and subchondral bone. Injection of calcium phosphate bone substitute into the area of subchondral bone edema (Subchondroplasty; Knee Creations, West Chester, PA) may be an option. We present a case of a lateral tibial plateau osteochondritis dissecans lesion treated with subchondral injection of nanocrystalline calcium phosphate. Preoperative magnetic resonance imaging is used to determine the area of subchondral edema, and intraoperative fluoroscopy is used to localize this area with the injection cannula. Calcium phosphate is injected by use of a series of syringes until the appropriate fill is obtained. Treatment of concomitant cartilage defects may also be carried out at this time.
剥脱性骨软骨炎病变在儿童和青少年中很常见。治疗具有挑战性，且取决于关节软骨和软骨下骨的状况。向软骨下骨水肿区域注射磷酸钙骨替代物（软骨下成形术；膝部创新公司，宾夕法尼亚州韦斯特切斯特）可能是一种选择。我们报告一例经软骨下注射纳米晶磷酸钙治疗的外侧胫骨平台剥脱性骨软骨炎病变。术前磁共振成像用于确定软骨下水肿区域，术中透视用于用注射套管定位该区域。使用一系列注射器注射磷酸钙，直到获得合适的填充量。此时也可对伴发的软骨缺损进行治疗。
