Background: Tibial plateau fractures are due to high energy trauma brought about by axial compressive force with a varus or valgus component. During 2018, there were 68 patients with tibial plateau fractures. 54 patients underwent surgical intervention in our institution.
Main Objective: The study aimed to compare the functional outcome and describe the demographic profile of patients with tibial plateau fractures from January to December 2018 treated with internal vs external fixation two years after surgery.
Methods: This study used a retrospective descriptive design to determine the distribution of demographics and functional outcomes of tibial plateau fracture patients who underwent surgery after two years. The Modified Rasmussen Score (MRS) determined clinical and radiographic parameters after taking knee radiographs and assessment by rehabilitation medicine.
Results: Study population was 48 patients, 35 underwent internal fixation through open reduction using plates or screws while 13 underwent external fixation. The demographic profile according to gender was majority of males (66.7%) and an age group of 20 to 49 years old (64.5%). In terms of mechanism of injury, most were due to motor vehicular accidents (93.7%) affecting the left lower extremity more (72.9%). The most common Schatzker Type was type VI with a total percentage of 39.6%. The computed mean MRS for internal fixation was 30.43 while external fixation was 30.00 showing no significant difference.
Conclusion: The surgical treatment of tibial plateau fractures involves restoring the articulating surface by anatomic reduction using internal or external fixation devices. The advantages of one over the other should be taken into consideration. There was no significant difference on the functional outcome of the two groups hence we can conclude that external fixation be chosen as the treatment of choice for tibial plateau fractures.
