Abstract

Objectives: Urinary tract infections (UTIs) are one of the most common infections that can lead to a devastating complicated total knee arthroplasty (TKA). The main objective of this research was to investigate the prevalence of UTIs among patients who underwent elective TKA and to look for scientific correlation between co-morbidities, gender, and post-operative care. Our review provides an insight into the local characteristics among our population. Methods: This is a retrospective chart review at a tertiary care hospital in Riyadh, Saudi Arabia. All patients from April 2006 to April 2018 undergoing TKA were included. We excluded patients with age less than 45 years, end-stage renal disease, and patients with history of oncological disease. Results: A total of 311 had TKA. 217 patients (69.8%) were females. The most prevalent comorbidity was Hypertension (68.5%) followed by Diabetes (51.8%). The rate of positive preoperative urinalysis and urine culture was (9.6%, 5.1%) respectively. Postoperatively, 8% of patients had a positive urinalysis and 6.1% had a positive urine culture. Age > 65, BPH in males, >33 BMI were statistically significant correlation with positive preoperative and postoperative urine tests. Conclusion: This study shows considerably high rates of UTI among TKA patients. It provides important correlations between the diagnosis UTIs and patients characteristics who underwent TKA.
