Periprosthetic patellar fracture fixation using suture anchors.

Treatment of type II periprosthetic patellar fractures presents difficulties in decision-making particularly when displacement is greater than 10 mm. Poor results have been reported with internal fixation, whereas conservative management has been associated with a high incidence of extensor lag. This article reports a patient with a displaced type II patellar fracture following total knee arthroplasty.
