Summary

The goal of this study is to compare the biomechanical stability and clinical outcomes of two treatment methods for inferior pole patellar fractures (IPPF): anchor suture with patellar cerclage and Kirschner-wire tension band combined with patellar cerclage. The study involves patients with IPPF, focusing on fracture patterns and treatment outcomes. 1. Undergo retrospective analysis of fracture patterns using fracture mapping. 2. Participate in biomechanical analysis via finite element modeling of both treatment methods. 3. Be part of a clinical comparison between two surgical treatments based on operative time, postoperative complications, and functional outcomes.

Interventions

Type	Name	Description
PROCEDURE	Anchor Suture with Titanium Cable Cerclage	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.
PROCEDURE	Kirschner wire tension band + cerclage cable	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.
