Background: Symptomatic hardware represents the most frequent complication reported following surgical treatment of patellar fracture. For this reason, some authors suggested using nonabsorbable sutures to fix the fracture with various techniques. The aim of this study was to evaluate clinical and radiological results of patients treated following a modified Pyriford technique using a FiberWire suture (Arthrex, Naples, FL, USA).
Materials And Methods: We retrospectively evaluated a case series of seventeen patients with displaced patellar fractures treated by open reduction and internal fixation with a modified tension band using FiberWire sutures. Clinical and radiological outcome were evaluated. Union time, complications, and reoperation rate were observed and recorded.
Results: All fractures healed (time to union 9.2 ± 2 weeks), and no fixation failure was observed. Slight losses of reduction (<4 mm) were noted in two patients at 4 weeks postoperatively. The average Lysholm and Bostman scores at the final follow-up were 91 ± 5.7 (range 83-100) and 28.3 ± 1.6 (range 26-30), respectively.
Conclusion: Modified tension band using FiberWire sutures showed satisfactory clinical results, with a low incidence of complications and reoperations. FiberWire tension bands could be used in place of metal-wire tension bands to treat patellar fracture, reducing the rate of symptomatic hardware.
Level Of Evidence: 4.

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.

Purpose: The purpose of this study was to evaluate the biomechanical properties of SutureTape as an alternative technique for arthrodesis of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint arthrodesis when compared with surgical steel wire.
Methods: A total of 32 fingers (index, long, ring, and small) from two matched pair cadaveric hands were used. K-wire and surgical steel wire were used for MCP and PIP joint arthrodesis of the control group (group I), whereas K-wire and SutureTape were used for the experimental group (group II).
