Evaluation of Functional and Radiological Outcomes in Transverse Patellar FracturesTreated with Cannulated Cancellous Screws and Anterior Tension Band Wiring (Code-T0313)

Introduction: Patellar fractures significantly impact knee function and mobility. Among various
surgical techniques, modified tension band wiring has been the traditional method for transverse
patellar fractures, but it has limitations such as implant migration and skin irritation. A newer
approach involving cannulated cancellous (CC) screws with anterior tension band wiring aims to
provide better stability, reduce hardware complications, and improve functional outcomes. This
study evaluates the functional and radiological outcomes of this technique in treating transverse
patellar fractures.
Aims and Objectives
Primary Objectives: To evaluate the functional and radiological outcomes of transverse patella
fracture treated with cancellous cannulated screw with anterior tension band wiring as assessed
by the Lysholm knee score in immediate , 1 month , 3 month, 6 month post operatively.

Secondary Objectives: To assess the functional outcomes of the cancellous cannulated screw
with anterior tension band wiring for the management of the transverse patella fracture in terms
of
1) Time of fracture healing
2) Hardware irritation
3) Lysholm knee score
Methods: A prospective study was conducted in a tertiary care hospital, including 35 patients
aged over 16 years with displaced transverse patellar fractures. Patients were treated with CC
screws and anterior tension band wiring. Functional outcomes were measured using the Lysholm
Knee Score at immediate postoperative, 1-month, 3-month, and 6-month intervals. Radiological
healing, fracture union time, and implant-related issues were assessed. Statistical analysis was
performed to determine the effectiveness of this technique.
Results: The technique showed superior fracture stability, faster healing times, and improved
knee function. Lysholm Knee Scores improved significantly over follow-ups. Implant-related
complications were minimal, with fewer cases of hardware irritation compared to traditional
methods.
Conclusion: Cannulated cancellous screws with anterior tension band wiring provide effective
fixation for transverse patellar fractures, ensuring faster healing, better functional outcomes, and
minimal implant-related issues.
