Fracture around stable patellar component and good bone stock
General considerations
If the patella component remains stable, standard cerclage compression wire fixation principles can be applied.
These fractures are classified by UCPF as V.34-B1.
Etiology
Fall onto flexed knee.
Imaging
Plain X-rays remain the first line of investigation.
CT Scan can be used to assess the size and position of the fragments and implant stability.
Comparison with previous X-rays is useful.
