Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Anchor + titanium cable cerclage (ISB-LP)
This group includes patients with inferior pole patellar fractures (IPPF) treated using anchor suture fixation combined with titanium cable cerclage. The intervention involves securing fracture fragments with anchors to provide stable fixation, reinforced by a titanium cable cerclage for additional stability. This method is intended to reduce hardware-related complications while maintaining biomechanical stability and supporting functional recovery. The outcomes for this group include operative time, postoperative knee range of motion, incidence of complications, need for secondary surgery, and functional scores such as the Bostman score.
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.
TBW-LP fixed (TBW-LP group)
This group includes patients with inferior pole patellar fractures (IPPF) treated using Kirschner-wire tension band combined with patellar cerclage (TBW-LP group). This intervention involves the placement of Kirschner wires to create a tension band construct across the fracture site, stabilizing the fragments, with additional support provided by a cerclage wire. This method is widely used in clinical practice due to its simplicity and cost-effectiveness. The study evaluates key outcomes for this group, including operative time, knee range of motion, incidence of postoperative complications such as hardware irritation or infection, and functional recovery based on Bostman scores. This group serves as a comparison to newer techniques like anchor suture with titanium cable cerclage.
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.
