Case ReportPeriprosthetic Femoral Supracondylar Fracture After Total Knee Arthroplasty With Navigation System

Case Report
The patient was a 53-year-old woman with left knee osteoarthritis. She was admitted to the authors' institution in February 2006. She complained of gross swelling, marked pain, and limited motion of the left knee. Past medical illnesses included hypertension, hyperlipidemia, and chronic renal insufficiency and were under regular medication control. She received right TKA 4 years ago. She was 147 cm in height and 80 kg in weight; her body mass index was 37.0. Physical examination at admission
Discussion
The first 2 reports of femoral supracondylar fractures associated with TKA were published in 1981 2, 3. The incidence ranged from 0.3% to 2.5% in the literatures 4, 5, 6, 7, 8, 9, 10. However, the elderly and osteoporotic population is rapidly increasing, and this possible risk of TKA should be given attention.
The mechanism of injury in periprosthetic fracture is usually a low-energy trauma, with the combination of abnormal axial and torsional loads. However, some other risk factors have been

Pin-Related Complications in Computer Navigated and Robotic-Assisted Knee Arthroplasty: A Systematic Review
2022, Journal of ArthroplastyAdverse Events Associated With Robotic-Assisted Joint Arthroplasty: An Analysis of the US Food and Drug Administration MAUDE Database
2022, Journal of ArthroplastyCitation Excerpt :Finally, in a randomized controlled trial with a minimum follow-up of 10 years, there was no difference in complication rates between robotic-assisted and conventional TKA [7]. Although broader postoperative complication rates following robotic-assisted arthroplasty appear comparable to manual surgery, complications specific to the use of computer-assisted navigation and robotic assistance have been reported and remain a risk not typically applicable to conventional TJAs performed without the use of these technologies [19–23]. Modern robotic-assisted arthroplasty systems typically require multiple bone pins to be temporarily placed either within the surgical field or through separate percutaneous incisions (2 femoral and 2 tibial pins for TKA, 2-3 pelvic pins for THA).

These pins have the theoretical risk of infection, fracture and post-operative discharge.27–30 This led to the development of a pinless reference system which uses external reference markers that are placed on the skin.
