Tibial plateau fracture is a rare complication of unicompartmental knee arthroplasty. The fracture almost always occurs during surgery, and it is likely to be the result of a technical error, usually an unnecessarily deep vertical saw cut into the proximal tibia. However, anything that weakens or overloads the proximal tibia may contribute to fracture, such as damage to the posterior cortex, excess removal of bone particularly in small patients with osteopenic bones, inadequate preparation of the keel slot, or use of excessive force with a heavy hammer. This series of eight case reports presents our experience with this complication after medial Oxford unicompartmental knee arthroplasty and outlines a treatment protocol.
胫骨平台骨折是单髁膝关节置换术的一种罕见并发症。骨折几乎总是发生在手术过程中，很可能是技术失误所致，通常是对胫骨近端进行了不必要的深切。然而，任何削弱或使胫骨近端负荷过重的因素都可能导致骨折，比如后皮质受损、过度去除骨质（尤其是骨质疏松的小个子患者）、龙骨槽准备不足，或使用重锤时用力过度。本系列八例病例报告介绍了我们在内侧牛津单髁膝关节置换术后处理该并发症的经验，并概述了治疗方案。
