We are reporting on a previously undescribed surgical approach and
postoperative protocol for the treatment of fractures of the lateral tibial
plateau in which there is a split pattern and depression of the articular
surface. In this approach the anterior horn of the lateral meniscus is
incised and detached so that the split fragment can be opened like a book.
Detachment and incision of the anterior horn minimizes the need to free the
lateral meniscus from its tibial attachment. The postoperative protocol
includes continuous passive motion followed by non-weight-bearing in a
toe-to-groin plaster cast for three months. Our preliminary results have
been encouraging, and arthroscopic examination in the seven knees so
studied indicated a healed fracture, restoration of the tibial articular
surface, and a healed lateral meniscus.
