Because of the lack of anatomical landmarks during reduction of multiple articular surfaces and fragments in comminuted patellar fractures, loss of bone fragments or aggravation of soft tissue and ligament injuries readily occurs. In the present case, we used multiple three-dimensional (3D)-printed guide plates to reduce and fix a comminuted patellar fracture. A 22-year-old man was hospitalized for 2 days because of left knee joint pain and limited movement caused by a traffic accident. Preoperative imaging revealed a comminuted fracture of the left patella (type 34-C3 according to the AO/OTA classification). Throughout a 2-year follow-up, the patient remained in generally good condition with no significant limitation of his left knee joint activity. Application of multiple 3D-printed guide plates is a safe and effective auxiliary technique for the treatment of comminuted patellar fractures. This novel technique can shorten the operation time, reduce the number of fluoroscopic procedures, and ensure fracture healing and recovery of knee joint function through reliable reduction of the articular surface.
由于在粉碎性髌骨骨折的多个关节面和碎片复位过程中缺乏解剖标志，骨碎片容易丢失或加重软组织和韧带损伤。在本病例中，我们使用了多个三维（3D）打印导板来复位和固定粉碎性髌骨骨折。一名 22 岁男性因车祸导致左膝关节疼痛和活动受限住院 2 天。术前影像学检查显示左侧髌骨粉碎性骨折（AO/OTA 分类为 34-C3 型）。经过 2 年的随访，患者一般情况良好，左膝关节活动无明显受限。应用多个 3D 打印导板是治疗粉碎性髌骨骨折的一种安全有效的辅助技术。该新技术可缩短手术时间，减少透视次数，并通过可靠的关节面复位确保骨折愈合和膝关节功能恢复。
