Surgical site infection (SSI) poses a significant risk in orthopedic surgery and can potentially lead to severe outcomes. Our recent study aimed to identify the predictors of SSI in patients undergoing surgery for closed patellar fractures. The study analyzed records of 2664 patients treated at two hospitals over a decade. The patients were divided into two categories, those who developed an SSI (SSI group) and those who did not (non-SSI group). The study identified several predictors of SSI, including elevated preoperative globulin levels, high-energy trauma, high ASA scores, and extended preoperative stays, serving as independent predictors.
Conversely, high albumin levels were found to be protective against SSIs. These findings emphasize the criticality of timely surgical interventions and regular biomarker assessments. However, for the complete validation of these findings, larger, prospectively collected datasets with standardized antimicrobial prophylaxis and prevention bundles will be essential.
Generally, patellar fractures are common knee injuries, usually resulting from direct trauma or from indirect forces. The incidence rate is around 13.5 per 100,000 people annually, often causing deep bone infections in the worst scenarios. Despite the clinical significance, research on the prevalence and risk factors of SSIs after patellar fracture surgery is sparse. The insights from this study, therefore, will assist healthcare providers in developing strategies to prevent SSIs, thereby improving patient care and outcomes.
The study involved a comprehensive review of electronic medical records for patients who underwent surgical treatment for closed patellar fractures. Patients eligible for inclusion were those who underwent surgical treatment for closed patellar fractures, had complete preoperative medical histories and follow-up records, and were over 18 years of age. This information was critical in identifying the predictors and devising preventive measures for SSIs in patients undergoing orthopedic surgery. The study carefully examined 72 variables potentially linked to the development of SSI. These variables included patient demographics, lifestyle factors, and a comprehensive range of preoperative laboratory indicators.
The data from this extensive analysis guided in the identification of independent risk factors and the determination of cut-off values for continuous variables related to SSIs. In conclusion, the study underscores the importance of understanding the potential predictors of SSI in patients undergoing closed patellar fracture surgery. These insights pave the way for improved surgical practices, effective patient management, and enhanced prevention strategies against SSIs, ultimately leading to improved patient care and outcomes in orthopedic surgery.
