Morphological Characteristics of Inferior Pole Patellar Fractures and a Finite Element Analysis Combined with a Retrospective Clinical Study of Anchor Suture and Titanium Cable Cerclage Treatment

This intervention involves the use of \*\*anchor suture fixation combined with titanium cable cerclage\*\* for the treatment of inferior pole patellar fractures (IPPF). The anchor suture provides stable fixation of fracture fragments by anchoring directly into the bone, while the titanium cable cerclage offers additional reinforcement around the patella to enhance stability and minimize fragment displacement. This method is specifically designed to address the limitations of traditional Kirschner-wire tension band techniques, such as hardware irritation and infection, by using biocompatible and low-profile materials.

This intervention uses \*\*Kirschner wire tension band combined with cerclage cable\*\* to treat inferior pole patellar fractures (IPPF). The Kirschner wires are positioned across the fracture site to form a tension band, which transforms tensile forces into compressive forces, promoting fracture stability. The cerclage cable is added to reinforce the fixation by encircling the patella, providing additional stability to comminuted or complex fractures.
