AbstractThe clinical and radiological outcomes of proximal tibia fractures involving the meta-diaphyseal junction treated with unilateral 3.5-mm locking precontoured anatomical plates are reported. Thirty-nine patients (41 proximal tibia fractures) who had proximal tibia fractures with complete meta-diaphyseal dissociation were enrolled in the study. For all patients, immediate postoperative and final follow-up simple radiographs were evaluated to determine the quality of the reduction by assessing coronal and sagittal alignment. In cases of intra-articular involvement, articular reduction quality and condylar width were additionally assessed. Clinical outcomes were assessed by knee range of motion and Lysholm knee score at final follow-up. Immediate postoperative radiographs showed satisfactory results: medial proximal tibial angle within 87°±5° in 87.8% (36 of 41), posterior tibia slope within 9°±5° in 85.4% (35 of 41), less than 2-mm articular step or gap in 79.3% (23 of 29), and a condylar width difference within 5 mm compared with the femoral condyles in 93.1% (27 of 29). All reductions but 1 were found to have satisfactory maintenance of the initial reduction. At final follow-up, the mean knee range of motion and Lysholm knee score were 122.5° (range, 100°-135°) and 75.8 (range, 50-100), respectively. A single lateral 3.5-mm plate fixation for proximal tibia fractures involving the meta-diaphyseal junction offers mechanically stable fixation with satisfactory clinical and radiological outcomes.
