[Objective] To introduce the surgical technique and preliminary clinical results of lateral locking plate and antero-posteri- or lag screws for fixation of collapsed fractures of the anterolateral tibial plateau. [Methods] A total of 26 patients received abovesaid surgi- cal procedures for Schatzker type Ⅱ tibial plateau fractures. Before operation, Mimics software was used to determine the position, direc- tion and length of the locking plate and antero-posterior lag screws in the digital model of the proximal tibia on the healthy side. After an anterolateral incision was made to explore the proximal tibia, the fractures were reduced and fixed with the lateral locking titanium plate se- lected according to the preoperative measurement with Mimics software on the contralateral proximal tibia, while two antero-posterior lag screws in appropriate lengths were implanted in the sagittal direction. [Results] The operation lasted for (72.6±4.3) min, associated with in- traoperative blood loss of (85.7±6.5) ml. All the patients resumed complete knee extension-flexion range of motion with significantly im- proved HSS score 1 year after operation (P＜0.05). Radiographically, the depth of articular surface collapse significantly reduced (P＜0.05), while the Rasmussen radiology score significantly increased postoperatively compared with those preoperatively (P＜0.05). All patients got fracture healing in 12~18 weeks postoperatively. The CT images showed good fracture reduction without articular surface collapse 1 year af- ter operation. [Conclusion] The lateral locking plate and antero-posterior lag screws plateau do achieve satisfactory clinical outcomes for collapsed fractures of the anterolateral tibial plateau, which might avoid secondary articular surface collapse.
