Arthroscopic-assisted Treatment of a Posterolateral Tibial Plateau Fracture with an Accompanying Tibial Eminence Fracture. Case Report.

Posterolateral tibial plateau fractures pose a challenge even to the most experienced orthopedic trauma specialists. Arthroscopic fracture management techniques have been emerging as an increasingly popular alternative in the treatment of selected tibial plateau fractures. This technique enables precise visualization of the articular surface of the tibia and its anatomical reduction with lateral meniscus repair, which further enables the restoration of biomechanical function of the meniscus and prevents early degeneration. In addition, this method minimizes soft tissue injury, shortens the duration of hospital stay and postoperative care, and enables treatment of accompanying intra-articular injuries. In our article, we present a case of posterolateral tibial plateau fracture with articular displacement and depression, and loss of support for the posterior margin of the lateral meniscus with an accompanying tibial eminence fracture. The fracture was treated with arthroscopic assistance. Anatomical reduction of the tibial eminence and the fragment of the posterolateral tibial plateau, as well as lateral meniscus repair was achieved intraoperatively. Postoperative radiographic assessment showed anatomical restoration of the articular surface. A full range of motion and pain-free knee stability were achieved following rehabilitation.
