The objective of this study was to evaluate the outcome of using beta-TCP in the treatment of depression tibial plateau fractures. A total of 124 patients with depression tibial fractures were included in this study and followed for a minimum of 12 months. All the cases were treated with open reduction and internal fixation, and grafted with beta-TCP ceramic. The clinical and radiological outcomes were assessed using Hospital for Special Surgery (HSS) score of knee and Rasmussen score during the follow-up. No obvious redisplacement was found at the follow-up assessment. Most of the patients had excellent HSS score and Rasmussen clinical score. Bone healing was noted in all fractures and Schatzker II-type fractures had the best functional outcome. The results suggested that using beta-TCP combined with open reduction and rigid internal fixation was an effective treatment for depression fractures of the tibial plateau.
