Periprosthetic tibial fracture with extraosseous cement

Case contributed by Dr Henry Knipe

Presentation

Disproportionate pain post right total knee joint revision.

Patient Data

Age: 60 years
Gender: Female

Long stemmed femoral and tibial component total knee replacement. Extraosseous cement is seen along the medial tibial cortex but no discrete fracture line is seen. 

Right total knee joint revision with long-stem femoral and tibial components. Periprosthetic fracture of the anteromedial tibial shaft with a small comminuted bone fragment superiorly and vertical extension. Associated small volume of extraosseous cement.

Case Discussion

Intraoperative fracture during total knee replacements is uncommon, with one series 1 reporting a rate of 0.7%. In this case, the extraosseous cement is the primary sign of a fracture, which is easily seen on CT.
