简要总结
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.
- Undergo retrospective analysis of fracture patterns using fracture mapping.
- Participate in biomechanical analysis via finite element modeling of both treatment methods.
- Be part of a clinical comparison between two surgical treatments based on operative time, postoperative complications, and functional outcomes.

结局指标
主要结局
final knee range of motion
时间窗: 6 months to 1.5 years after surgery
The final knee range of motion is assessed to evaluate the functional recovery of patients following surgical treatment for inferior pole patellar fractures (IPPF). This measure includes the degree of flexion and extension achieved during follow-up, as documented through physical examination and patient self-reports. The range of motion is compared between the two intervention groups to determine the effectiveness of each treatment method in restoring knee functionality and mobility. Outcomes are measured and analyzed based on clinical standards and benchmarks for knee rehabilitation.
incidence of secondary surgery
时间窗: 6 months to 1.5 years after surgery
The incidence of secondary surgery is defined as the number of patients who require an additional surgical procedure related to the treatment of inferior pole patellar fractures (IPPF) within the follow-up period. This includes procedures to address complications such as hardware irritation, infection, nonunion, malunion, or mechanical failure of the initial fixation. The data will be compared between the two intervention groups to evaluate the durability and long-term effectiveness of each surgical technique. This measure provides critical insights into the need for re-intervention and overall treatment success.
postoperative complications
时间窗: 6 months to 1.5 years after surgery
Postoperative complications include any adverse events or clinical issues occurring as a result of the surgical treatment for inferior pole patellar fractures (IPPF) within the follow-up period. These complications may include, but are not limited to, hardware irritation, infection, wound dehiscence, delayed union, nonunion, or malunion. Data will be collected from medical records and follow-up visits to identify the frequency and types of complications in each intervention group. The results will be analyzed to compare the safety profiles of the anchor suture with titanium cable cerclage and the Kirschner wire tension band with cerclage cable techniques. This outcome is critical for assessing the overall safety and effectiveness of each surgical approach.
