Transverse fractures of the patella

A technique termed longitudinal anterior band with or without cerclage (LAB/C) is recommended for internal fixation of transverse patellar fractures. The fixation is secure even with the existence of considerable comminution in one fragment. The security of this fixation allows early mobilization and the prevention of knee stiffness. The technique involves longitudinal drill holes through which a wire is pulled and looped over the anterior surface of the patella. When folded and tied over the patella, it allows excellent anterior compression and firm fixation. A cerclage wire is applied primarily for marked comminution. Sixteen patients have been treated in this manner with excellent results. To date there have been no complications from wire breakage or fragment distraction, and early motion has been achieved.
