Comparing Single-locking and Double-locking Plate Fixation Methods in Patients With Proximal Tibial Fractures

Proximal tibial fractures account for 1% of all fractures. Different treatments have been proposed for this fracture. 

The present study aims to evaluate the clinical and radiological results of single-locking and double-locking plate fixation methods in patients with proximal tibial fractures.

The present study was carried out on 40 patients with proximal tibial fractures referred to Imam Khomeini Hospital in Sari, Iran. They were divided into two groups of double-locking fixation with 3.5-mm Locking Compression Plate (LCP) and single-locking fixation with 4.5-mm LCP. They were followed up for at least 6 months after surgery. At the time of admission, they were assessed using Lysholm Knee Scoring Scale and Visual Analogue Scale. Radiographs were taken from all patients and the articular surface, and fracture healing,. 

Of 40 patients, 17 and 23 were treated with 3.5-mm and 4.5-mm LCPs, respectively. The mean Lysholm score in the groups with 3.5-mm and 4.5-mm LCPs was 84±8.2 and 78.3±16.2, respectively. There was no statistically significant difference between the two groups (P>0.5). 

The radiological and functional outcomes were almost the same for single-locking and double-locking plate fixation methods. Both methods can be used to treat the tibial plateau fracture. The treatment can be selected according to the surgeon and the patient’s request
