Intraoperative tibial plateau fracture during bone preparation in a cruciate retaining primary total knee arthroplasty.

Intraoperative fractures are a rare complication in total knee arthroplasty. Limited literature exists in regard to the incidence, mechanism of injury and management of intraoperative fractures. The authors report a unique case of an 80-year-old man who sustained a medial tibial plateau fracture that occurred intraoperatively during final tibia bone preparation with the use of the Woolley Tibia Punch (Innomed, Savannah, Georgia, USA). The fracture was managed with the addition of 4.5 mm cortical lag screws and the addition of a stemmed tibial implant to bypass the fracture. This is the first reported case in literature that describes an intraoperative medial tibial plateau that occurred through the use of a Woolley Tibia Punch. The authors recommend the consideration of drilling to prepare sclerotic bone for cement penetration rather than a punch in order to minimise the potential for intraoperative fractures that may occur with the use of a punch. © BMJ Publishing Group Limited 2020.
