The authors reviewed postoperative tiblo-femoral angular changes from the twenty six cases of supracondylar and intercondylar fractures of the femur treated operatively from January, 1988 to December, 1991. Fractures of a single condyle were excluded. The fractures were fixed internally with dynamic condylar screw(DCS) in nine cases, anatomic plate in nine, dynamic compression plate(DCP) in six and others in two. During the periods of follow up there noted varus change of 3.7 degrees in average. We reviewed retrospectively these postoperative varus or valgus angular changes with reference to the degree of injury, type of fracture, time elapsed from injury to operation, kind of internal fixation device, initial bone graft and postoperative brace supplement. Less angular changes in the tiblo-femoral angle with better results were noted in cases with lower energy injuries, AO type Al, A2 or Cl fractures, operation within 1 week of injury, internal fixation with DCS, initial bone graft and postoperative corrective brace supplement.
