Kirschner's wire tension band was the first choice in the treatment of patella fracture. But the principle of tension band had been misunderstood for long time. In the traditional principle, it was believed that tension band could change the separating force between fracture fragments into compressing stress when exercising. Eccentric fixation and articular surface cracking were disadvantageous. These could make the fracture fragments separate either at resting or exercising, which cause the gaps without pressure. Thus excercising could not change the separating force into compressing stress.

This review examines the giant elastic protein titin and its critical roles in heart function, both in health and disease, as discovered since its identification nearly 50 years ago. Encoded by the TTN (titin gene), titin has emerged as a major disease locus for cardiac disorders. Functionally, titin acts as a third myofilament type, connecting sarcomeric Z-disks and M-bands, and regulating myocardial passive stiffness and stretch sensing.

Background: Patellar fractures present challenges in treatment, with traditional methods often leading to complications such as loss of reduction and implant failure. This study aimed to compare a novel suture fixation technique with the traditional tension band method using finite element analysis.
Methods: CT images of a healthy 35-year-old male were used to construct 3D patellar models.

We studied the correlation between changes in the interscrew angle (screw divergence) and the correction achieved with tension band plates applied for valgus deformities of the knee region. Twenty-eight children with 68 operated physes were included in this retrospective review. The interscrew angle and screw trajectory angle were measured in the initial and follow-up radiographs.

This article aims to present a comprehensive technical note detailing our preferred treatment approach for tibial tuberosity avulsion fractures in the adult and elderly populations, particularly in scenarios characterized by low tissue quality and limited bone stock. Existing literature on this fracture type is scarce, with many described techniques relying on optimal bone quality for effective screw fixation of the tibial tuberosity. Various methods for tibial tuberosity avulsion fixation include K-wires, cannulated screws, staples, tension bands, suture anchors, and in select cases, direct transosseous sutures.

Case: A 67-year-old woman sustained a periprosthetic tibial tubercle avulsion fracture with extensor mechanism disruption. She underwent open reduction internal fixation (ORIF) with orthogonal mini-fragment plates applied in a tension band fashion with patellar tendon suture augmentation. Radiographs, range of motion, and patient-reported outcomes were completed over 1 year.
