Reduction of the depressed joint surface in tibial plateau fractures leaves large cancellous bone defects. These metaphyseal defects are usually filled with autogenous bone grafts that cause significant donor site morbidity. The use of injectable tricalcium phosphate gives the opportunity to support the reduced joint surface without bone grafting. Objective: The aim of this study was to evaluate the functional and radiological outcomes of closed/open reduction and internal fixation, augmentation with injectable tricalcium phosphate in tibial plateau fractures. Methods: This prospective study includes 20 patients, with mean age of 44.4 years. According to the Schatzker’s classification, there were 12 fractures of type II, one fracture of type III, five fractures of type V, and two of type VI. Intervention: All the patients underwent closed/ open reduction, osteosynthesis with screws or plate, and injection of tricalcium phosphate injection in the subchondral bone defect. The patients were reviewed at an average follow up of 15.35 months (range 6-28 months). Rasmussen’s clinical and radiological score was used to assess the patients post-operatively and during follow-up period. Results: Union was achieved in all patients. Rasmussen's radiologic score was excellent in 2 patients (10%), good in 17 patients (85%), and fair in 1 patient (5%). Rasmussen’s clinical score was excellent in 6 patients (30%), good in 13 patients (65%), and fair in 1 patient (5%). Conclusion: The results show that injectable tricalcium phosphate is a safe and useful alternative to bone grafting in tibial plateau fractures which have high compression strength and allows early partial and full weight bearing.
