ABSTRACT
Background and objective Multiligament knee injuries (MLKIs) are difficult to treat, and poor outcomes have been reported after conservative management. Controversy exists as to how to surgically manage these complex injuries. The aim of our study was to evaluate the midterm patient-reported outcomes after delayed multiligament knee reconstruction. Methods This was a review of a prospectively kept database of all patients undergoing surgery for multiligament reconstruction at a single institution. A total of 51 patients were included in the study, with a median follow-up of 48 months. In addition to the patient-reported outcomes, we also looked at other factors that could potentially affect the outcomes. Results At the final follow-up, there was no significant difference between the range of motion (ROM) of the injured knee compared to that of the healthy knee. Patients having surgery >6 months after injury had similar outcomes when compared to those having surgery <6 months post-injury. Female patients and patients with a BMI >30 had inferior outcomes. Conclusion Good midterm results can be expected after delayed multiligament knee reconstruction. Patients with a BMI >30 and female patients were observed to have inferior outcomes.
