INTRODUCTION
With the increasing use of robotic-assisted total knee arthroplasty (RATKA), pin-related complications are uncommon, but can be distressing to both the surgeon and patient. We encountered two cases of tracking pin-related distal femoral and proximal tibial fractures and treated them surgically.
CASE REPORT
Two patients developed fractures in the postoperative period following RATKA. A 67-year-old female presented with a minimally displaced tibial fracture, which was treated with open reduction and internal fixation using a narrow plate. A 69-year-old female developed a minimally displaced femoral fracture and underwent internal fixation with a broad plate.
CONCLUSION
At the latest follow-up, the fractures healed completely. After changing the position of the tracking pin from the diaphysis of the femur and tibia to the metaphyseal area of the distal femur and proximal tibia using a 3.2 mm diameter pin, we have not yet encountered any more pin site fractures.
引言
随着机器人辅助全膝关节置换术（RATKA）的使用日益增加，与销钉相关的并发症并不常见，但对外科医生和患者来说都可能令人苦恼。我们遇到了两例与跟踪销钉相关的股骨远端和胫骨近端骨折，并对其进行了手术治疗。
病例报告
两名患者在RATKA术后出现骨折。一名67岁女性出现轻度移位的胫骨骨折，采用窄钢板切开复位内固定治疗。一名69岁女性出现轻度移位的股骨骨折，并采用宽钢板进行内固定。
结论
在最近的随访中，骨折完全愈合。在将跟踪销钉从股骨和胫骨骨干的位置改为使用直径3.2毫米的销钉置于股骨远端和胫骨近端的干骺端区域后，我们尚未再遇到任何销钉部位骨折。
