Anatomical considerations and a clinical end-result study of 100 fractures emphasize the vulnerability of the lateral tibial plateau to a valgus force on the extended knee.
Type I, non-displaced fractures, can be successfully treated by an initial period of traction with early institution of active knee exercises and subsequently prolonged protection from weight-bearing.
Type II, local compression fractures of the lateral plateau, are successfully managed by conservative methods recommended for Type I fractures.
Type III, displaced fractures, may require open reduction to restore joint stability. Postoperative care is based on principles followed in the treatment of Type I and Type II fractures.
Early mobilization of the knee is the key to restoration of maximum joint function.
