All-in-one management of chronic traumatic multiligament knee injury ( 2–5-year follow-up)

Abstract

Background Dislocation of the knee is a relatively rare injury; with modern arthroscopic techniques, operative reconstruction has become the standard of care. Simultaneous reconstruction of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL), and repair or reconstruction of the medial and lateral structures have been recommended. Objectives The purpose of this study was to evaluate the clinical results of all-in-one reconstruction of chronic multiligamentous knee injuries using an autogenous graft. Patients and methods Fifteen patients (nine men and six women) underwent all-in-one reconstruction. Six patients had all-in-one ACL, PCL, and medial collateral ligament reconstruction. ACL, PCL, and lateral and/or posterolateral structures were reconstructed in five patients. The average duration of the time from injury to surgical intervention was 4.8 months. Results Function of the operated knee was evaluated according to the Lysholm knee scale. Thirteen of 15 patients showed good outcome. The average patient age at surgery was 34 years and the average postoperative follow-up period was 53 months, with a median of 60 months. Only two patients had loss of extension up to 10π. One patient had knee stiffness and required arthroscopic adhesolysis at 6 months postoperatively. The average Lysholm score was 81. Conclusion The results showed the effectiveness and safety of all-in-one reconstruction of combined chronic multiligamentous knee injuries that can adequately restore satisfactory knee stability and function.
