Arthroscopic internal fixation of fractures of the intercondylar eminence of the tibia.

We treated a 53-year-old man with a fracture of intercondylar eminence of the tibia. He had a nondisplaced (type I) fracture at the first examination and was treated by long leg cast. However, 4 weeks later, it was found that the fracture was displaced, which suggests that nondisplaced fracture of intercondylar eminence may displace later. We recommend primary arthroscopic fixation for type I fractures of the intercondylar eminence of the tibia, because it is difficult to reduce the fragment arthroscopically once it is displaced. This report describes a new technique of arthroscopic reduction and internal fixation for the fractures intercondylar eminence of the tibia.
