Abstract
Abstract
Introduction: The patella has an important role in knee extension and shock absorption. This retrospective study assessed factors influencing surgical outcomes of patellar fractures over ten years at a single center.
Methods: A descriptive-correlational design was applied to patellar fracture cases treated at a university center over a decade. Patients were stratified into follow-ups of <5 or ≥5 years. Data included demographics, medical history, functional outcomes (Koo’s and WOMAC indices), pain, range of motion, and osteoarthritis severity (Kallgren/Lawrence classification). Census sampling was used. Analyses were performed in SPSS, with visualizations in Excel and GraphPad Prism.
Results: Among 53 patients (mean age 60.45 ± 16.00; 90.6% male), 62.3% had <5-year and 37.7% had ≥5-years follow-up. Follow-up duration did not correlate with outcomes. Treatment complications significantly correlated with degenerative arthritis. Functional scores were higher (p < 0.05) and pain scores lower (p < 0.05) in patients without complications.
Conclusion: Patellar fracture surgery yielded favorable mid-term outcomes, with complications linked to poorer function and higher pain. Reoperation rates were low, supporting surgical efficacy.
