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

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.

Inclusion Criteria:

(1) diagnosis of IPPF confirmed by X-ray or CT, and (2) patients aged between 18 and 70 years.

Exclusion Criteria:

(1) concomitant fractures of other parts of the knee, (2) open fractures, and (3) pathological fractures.
