RT Journal Article SR Electronic T1 Acute presentation of a proximal fibular stress fracture after a total knee arthroplasty JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e234954 DO 10.1136/bcr-2020-234954 VO 14 IS 3 A1 Shibby Robati A1 Muattaz Kazzam A1 Daniel McIntyre A1 David G Wood YR 2021 UL http://casereports.bmj.com/content/14/3/e234954.abstract AB A 67-year-old woman underwent a routine and uneventful elective total knee arthroplasty for osteoarthritis at our centre. No intraoperative nor immediate postoperative complications were noted clinically nor radiologically. At 5 weeks postoperative, she began to notice some new discomfort in her upper calf area, with no preceding history of trauma. A Doppler ultrasound scan ruled out a deep vein thrombus. Only on further re-imaging of her knee with X-rays and CT was there shown to be a fibular fracture of the proximal third with evidence of callus formation. The pain arising from her stress fracture delayed her rehabilitation slightly, going on to require a successful manipulation under anaesthetic (0°–95°). She went on to have excellent function in her knee and the pain from the stress fracture had settled by 5 months.
