34-week follow-up of suture anchor fixation for a traumatic patellar fracture overlying a total knee arthroplasty

Traumatic patellar fractures following total knee arthroplasty (TKA), in the absence of patella resurfacing, are uncommon but debilitating injuries. Open reduction and internal fixation is associated with significant complications, thus conservative management is often preferred. We report the first known publication of the fixation of a comminuted periprosthetic patellar fracture using suture anchors, with good results at 34-week postoperative follow-up. The suture anchor technique offers an alternative option in the management of traumatic periprosthetic fractures of the unresurfaced patella, where tension band and cerclage wiring are not possible due to fracture comminution and poor bone quality.
