Abstract

Objectives: Fractures located at the inferior pole of the patella pose challenges in terms of fracture 
fixation, primarily due to inadequate bone quality at the lower pole and typically limited options for 
secure fixation. This study introduces a novel approach that i nvolves employing the Krackow suture 
technique on the patellar tendon, followed by a longitudinal transosseous and upside -down fixation at 
the superior aspect of the patella using a suture anchor to address this challenge.
Methods: A retrospective cohort case series was conducted at a single center, involving ten patients with fractures 
at the lower pole of the patella. Follow-up assessments were performed for a minimum of six months to observe 
postoperative gap formation and evaluate bony union. Knee motion, pain, function, and any intra- and postoperative 
complications were documented throughout the follow-up periods.
Results: All patients exhibited complete bone union without gap formation six months postoperatively, accompanied 
by a regained full range of motion without any functional limitations. No instances of postoperative anterior knee 
pain, refracture of the inferior patellar pole, or other complications were reported during the follow-up period.
Conclusion: The innovative technique involving longitudinal transosseous and upside-down suture anchor repair 
for the management of inferior patellar pole fractures is a straightforward and easily executable surgical procedure. 
This method offers stable fixation and yields favorable functional outcomes.
