Introduction:
Patella fractures are intra-articular fractures of the knee where most of the cases represent separated and displaced following fractures. Titanium-nickel shape memory alloy is characterized by shape-memory effect, super-elasticity, excellent fatigue behavior, corrosion resistance, acceptable biocompatibility and high damping capacity.The incidence of patella fractures accounts for 1% to 2% of human fractures . At present, there are many internal fixation methods for the treatment of patella fractures. Among them, the common methods include Kirschner wire tension bands, screws, steel wire cerclage, titanium cable cerclage, memory alloy patella claw (patella concentrator), and silk purse-string suture . Memory alloy patella claws have been used to treat patella fractures for more than 30 years . It conforms to the principle of tension band fixation, and the fixation is firm. In addition, it can allow patients to perform early functional exercises, the patients recover quickly after the operation, and there is no phenomenon such as the top abrasion of Kirschner wires after the operation .
