Clinical outcome in patients with posterolateral corner injuries of the knee with la prade technique

Abstract

Introduction: Injuries to the posterolateral structures of the knee are commonly caused by sports injuries, falls, and vehicle accidents. A direct hit on the proximal tibia when the knee is in stretched condition may cause an isolated posterolateral injury. The PLC is primarily responsible for resisting varus angulation and external rotation in addition to posterior displacement of the tibia. It is extremely important that the functionality of the PLC and tibiofibular joint be checked along with other clinical tests when diagnosing a knee injury. Aim of the study is to know the clinical outcome ofLaprade technique for posteriolateral corner injury of the knee.Materials and Methods: A total of 20 patients were included in this study with posterolateral corner injury and were operated by La Prade technique. Results: In this study, the preoperative range of motion was measured with goniometer. Normal range of motion (0-1400) was seen in 8 patients (40%), 6 patients (30%) had good range of motion (0-1200). 2 patients (10%) had range of motion (0-1100), 2 patients (10%) had range of motion (0-1000), 2 patients (10%) had (0-900) range of motion. Post operatively 15 patients (75%) had full range of motion (0-1400).1 patient (5%) had (0-1300) range of motion, and 4 patients (20%) had range of motion (0-1200).Conclusion: The posterolateral knee reconstruction technique or La Prade technique presented here significantly improved objective stability in patients with a chronic posterolateral knee injury.
