Osteoporosis is a disease of low bone mass which leads to an increased risk of fracture. The prevalence of osteoporosis is greatest amongst postmenopausal women who also form a large portion of patients with osteoarthritis presenting for total knee arthroplasty. We present a case of a 77-year-old female with knee osteoarthritis and osteoporosis on denosumab who underwent robotic-assisted total knee arthroplasty. Postoperatively, she suffered an atraumatic midshaft femur fracture at the pin site associated with the use of intraoperative robotic technology. This is a unique complication related to the use of robotics which requires additional skeletal fixation versus standard arthroplasty surgical technique. We recommend caution and further study regarding the use of robotics in total knee arthroplasty in the setting of osteoporosis and denosumab use.
骨质疏松症是一种骨量低的疾病，会导致骨折风险增加。骨质疏松症在绝经后妇女中最为常见，而绝经后妇女也是接受全膝关节置换术的骨关节炎患者的主要人群。我们报告了一例 77 岁女性患者，她患有膝关节骨关节炎和骨质疏松症，正在使用地舒单抗治疗，随后接受了机器人辅助全膝关节置换术。术后，她在术中机器人技术相关的针道处发生了无创伤性股骨干骨折。这是一种与机器人使用相关的独特并发症，需要额外的骨骼固定，而不是标准的关节置换手术技术。我们建议在骨质疏松症和地舒单抗使用的情况下，对机器人在全膝关节置换术中的使用保持谨慎并进一步研究。
