Migration to the popliteal fossa of broken wires from a fixed patellar fracture.

Breakage of K-wires and wires which are used for fracture fixation is not uncommon, but migration is rare. The authors experienced two cases of symptomatic migration of broken K-wire and wires used for patellar fixation to the popliteal fossa. Migration of broken hardware happened 3 and 4 years after fixation. The broken hardwares were removed surgically. We would like to suggest that K-wire and wire fixation used for treatment of patella fractures can migrate into the posterior compartment of the knee and cause clinical symptoms. Correct surgical technique and fixative choice should be considered for treatment of the patellar fracture.
