INTRODUCTION: Fracture-related infection (FRI) poses a substantial challenge in orthopaedic trauma surgery, potentially leading to permanent functional impairment or necessitating amputation in patients who are expected to recover fully. Data on the incidence, pathogen detection rates, outcomes, and optimal management strategies for patellar FRI are limited. Therefore, this study aimed to identify the most common pathogens associated with patellar fixation-related infections, evaluate the functional outcome associated with FRI of the patella, and develop a management algorithm for addressing these severe complications.
METHODS: This retrospective review analyzed a prospectively maintained database to identify all patients with FRI of the patella treated at our institution between January 2015 and August 2023. Data on demographics, fracture characteristics, surgical details, and outcomes were collected. Descriptive statistical analyses were performed using SPSS software.
RESULTS: Over the 9-year period, 32 cases of patellar fractures complicated by infection following surgical treatment were identified, with complete follow-up data available (mean age, 56.5 ± 15.8 years). Infection occurred in 13 patients within 2 weeks of fixation and in 19 patients between 2 and 10 weeks postoperatively. Following debridement, nine patients retained their original fixation, eight underwent hardware removal, and 15 underwent hardware replacement. Seven patients developed septic arthritis and were managed with arthroscopic knee lavage. Metagenomic next-generation sequencing demonstrated a sensitivity of 93.8 % (30/32), which was significantly higher than that of traditional microbiological culture (53.1 %; P < 0.01). All surgical incisions achieved primary healing within 2 weeks post-closure with no recurrence of infection, skin necrosis, osteomyelitis, or nonunion. At the final follow-up, all fractures had united, with the Böstman patellar fracture functional scores ranging from 24 to 29, resulting in a 100 % excellent/good rate.
CONCLUSIONS: Comprehensive and multidisciplinary management approaches can achieve successful bone union and favourable long-term outcomes in patients with patellar FRI. However, further validation through large-scale studies is necessary to confirm these findings.
