Clinical Outcome of Cannulated Screw Fixation with Suture Tape Augmentation in Geriatric Transverse Patellar Fracture - A Case Series.

Introduction: Patellar fractures were common and often challenging to manage, particularly in the elderly population. Achieving stable anatomic reduction and maintaining it throughout the perioperative period was crucial for restoring knee function, especially in patients with osteopenic bone. Material and Methods: This was a retrospective case series of geriatric patients who presented to our centre with closed transverse patellar fractures between 2022 and 2023. All fractures were classified as AO 34C1 under the Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification and were considered fragility fractures, having resulted from a fall from standing height. Only patients aged over 60 years were included. All underwent open reduction and internal fixation using cannulated screws with suture tape augmentation. The Knee Society Score (KSS) was evaluated at four months post-operatively, and patients were followed for complications for up to one year. Results: Six cases met the inclusion criteria. The mean displacement was 19mm, and the average operative time was 45.17 minutes. The average time to radiographic union was 8.67 weeks. At a mean follow-up of 12.8 months, none of the patients required revision surgery or hardware removal. No patient reported issues related to implant prominence or pain during kneeling. The KSS at four months ranged from 87 to 97, with a mean score of 91. Conclusion: Cannulated screw fixation with suture tape augmentation appeared to be a safe and effective method for treating transverse patellar fractures in the elderly population, offering stable fixation and favourable functional outcomes.
