ABSTRACT

Objectives: This study was designed to determine the accuracy of the Ottawa Knee Rule (OKR) when applied to patients with acute knee injury reported at Lancashire Teaching Hospitals NHS Foundation Trust.
Methods: This prospective study included a convenience sample of all patients with a blunt knee injury presenting to the emergency department of our hospital during the study period. Standard knee radiographs were ordered on all patients irrespective of the determination of the rule.
Results: A total of 70 patients were enrolled in the study. 3 fractures (6.66%) were detected out of 45 patients who undergone X-ray and met the rule. The potential reduction in use of radiography was estimated to be 28.6%. The OKR missed only one fracture.
Conclusion: Ottawa knee rule is a highly sensitive tool for detecting knee fractures and has the potential to reduce the number of radiographs in patients with acute knee injuries. Key words: Ottawa Knee rule.
