Aim : We investigated the combination of closed reduction, percutaneous osteosynthesis with screws and external fixation in the treatment of high-energy fractures of the tibial condyles with severe soft-tissue lesions.

Method : We studied 35 fractures (11 open) of the tibial condyles. Twenty-eight were Schatzker type VI, 5 type V and 2 type I. The fracture was reduced under fluoroscopic control and the articular surface was fixed with cannulated lag screws. In 23 patients (group A) a unilateral external fixation was applied with the proximal pins placed in the tibial condyles. In 12 patients (group B) an external fixation crossing the knee was used for 6 weeks followed by a knee brace. The follow-up period was 8–45 months

Results: All fractures united in a mean time of 15 weeks except for two in group A that needed conversion to internal fixation. Ten knees developed pintract infection. All knees had range of motion of at least 1000 except for one in group B that developed osteoarththritis. A collapse of the articular surface of more than 5mm and malalignment of more than 60 were observed in 7 and 5 patients in group A and B respectively.

Conclusions: Limited internal and external fixation are a satisfactory technique for selected fractures of the tibial plateau, particularly with poor soft-tissue envelope. Crossing the knee with the external fixator does not necessarily lead to significant stiffness.
