Nonunion after a tibial shaft fracture complicating tibial tubercule osteotomy.

Tibial shaft fracture after tibial tubercle osteotomy in total knee replacement is a rare complication. We report on a 67-year-old man who had a knee revision arthroplasty in which a long tubercle osteotomy was performed to facilitate exposure. Three weeks after surgery, he presented with a transverse shaft fracture, which became a nonunion requiring surgical management. This shaft nonunion and its solution after tibial tubercle osteotomy is discussed as well as relevant literature.
