Combined Intraoperative Arthroscopic and Fluoroscopic Guided Reduction of a Lateral Tibial Plateau Fracture Using Minimally Invasive Metaphyseal and Intraarticular Fixation: Description of a Surgical Technique.

Tibial plateau fractures are quite common among lower limb fractures. Several fracture classifications exist including Schatzker classification, in which tibial plateau fractures are divided into six types where each increasing numerical category indicates increasing severity of the injury and worsening prognosis. Arthroscopic-assisted techniques using a lateral or medial metaphyseal window have shown results comparable to open internal fixation methods with multiple advantages. We present a case of a medically and surgically free 40-year-old lady who presented to our emergency department complaining of left knee pain following a fall from the stairs. Clinically there was significant swelling and tenderness over the lateral aspect of the left proximal tibia, radiographs showed a Schatzker type III tibial plateau fracture, confirmed by computed tomography (CT). A combined intraoperative arthroscopic- and fluoroscopic-guided reduction of the articular depression through a lateral cortical window was achieved and the fracture was fixed using a minimally invasive fixation technique. The postoperative course was uneventful. The patient had recovered full range of motion and the wounds were barely visible. One-year X-ray showed healed fracture without any evidence of displacement or subsidence.
