Interventions

DEVICEPatella Anatomical Locking Plate

Patients in the patella anatomical locking plate group will undergo internal fixation with an anterior locking plate and screw construct using the 2.7mm variable angle (VA) locking patella plating system (DePuy Synthes, Zuchwil, Switzerland)

DEVICETension Band Wiring

Patients in the tension band wiring group will undergo open anatomical reduction and internal fixation with a tension band wire construct.
