IntroductionUpdated three column fixation of tibial plateau fractures (TPFs) arouse the importance of posterior column articular reduction. Complex TPFs with posterolateral (PL) articular injury is difficult to manage. We presented a strategy of combined positions and approaches to treat these injuries. Surgical technique was described and outcome of these were reported.Materials And MethodsFrom 2014 Jan to 2016 Dec, there were 132 patients of TPFs treated in our institute. Preoperative evaluation included plain films and 2D/3D CT scan to evaluate the involvement of articular surface and associated columns. Inclusion criteria were three column TPFs with PL corner injury. We put patients in prone position first with reverse L incision to manage PL articular impaction and posteromedial (PM) fractures. Then we repositioned the patients in supine to treat anterolateral fixation. Postoperative radiographic analysis, physical examination findings, and patient reported outcome scores from the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire were recorded.ResultsPatient demographic information was retrospectively reviewed with a mean follow-up time of 34.4 months (range 24-48 months). The average time to union was 5.2 months (range 4-8months). 13/16 (81%) of patients had satisfactory articular reduction by plain films (less than 2 mm articular step off). All patients demonstrated healed without secondary displacement or infection. All patients demonstrated satisfactory coronal (medial proximal tibia angle 84.68 degrees) and sagittal alignment (posterior proximal tibia angle 84.75 degrees). Condylar width averaged 3.93 mm. 3/16 (19%) of cases required posterolateral columnar plating in addition to posteromedial columnar plating. The knee range of motion averaged 115 degrees (ranged from 0 degrees of extension to140 degrees flexion). The average KOOS score was 83/100 (range 76-90). 3 patients in the series developed a surgical site superficial infection and resolved after debridement and oral antibiotics use. No patient eventually received total knee arthroplasty at the last follow up.ConclusionsOur strategy provides an effective method to treat three column tibial plateau fractures with PL articular injury.Copyright © 2019 The Author(s).
