Functional Outcomes of Internal Fixation of Complex Tibial Plateau Fractures: A Case Series

Aim: To study the functional outcomes of internal fixation in complex tibial plateau fractures. Materials and Methods: 51 patients presenting with complex tibial plateau fractures were treated between January,2013 to January,2016 with various modes of internal fixation depending on the fracture type. Subsequently the patients were followed up at 2,6,12,18 and 24 weeks and then at intervals of three months. Early mobilization was encouraged, and weight bearing was allowed on the basis of callus formation. The functional results were evaluated using the criteria of The Knee Society Clinical Rating System. Results: 18 patients of Schatzker type VI fractures were treated, out of which 9 were treated using only lateral plates, 7 were treated using lateral plates and additional cancellous screws, and 2 were treated using bicondylar plating. 15 patients of Schatzker type V were treated, out of which 10 were treated using lateral lock plates and cancellous screw medially, 4 were treated using only lateral lock plates and 1 was treated with bicondylar plating. Remaining 18 patients of Schatzker type II,III,IV were treated using either only screws or lateral lock plates, buttress plates and screws with or without bone graft. The mean follow up was 1 year (range 10 months to 34 months). All patients were followed up, and their functional outcome was recorded. Conclusions: Good results were obtained with internal fixation. There was good range of motion at the knee joint and excellent functional results.
