Functional & Radiological Outcomes of Knee Joint After Surgical Treatment of Proximal Tibial Fractures With Hybrid External Fixator

Objective: To determine the functional and radiological outcomes of the knee joint in Schatzker Type V and VI proximal tibial fractures treated with a hybrid external fixator. Methodology: This prospective observational study was conducted in the Department of Orthopedic Surgery, Services Hospital Lahore, from September 2018 to April 2020, following approval from the Hospital Ethical Review Board. Adult patients aged 21 to 70 years with Schatzker Type V and VI proximal tibial fractures were included. Patients with polytrauma, associated head or spinal injuries, or previous injuries around the knee joint were excluded. A total of 60 patients (ages 18 to 70 years) with Schatzker Type V (n=40) and Type VI (n=20) fractures were enrolled. Preoperative knee joint X-rays (anteroposterior and lateral views) were performed. A two-ring hybrid external fixator was applied in all cases. Patients were followed for one year postoperatively, and functional and radiological outcomes were assessed using the Rasmussen Score. Results: At the final follow-up, the functional Rasmussen Score was excellent in 12 patients, good in 45, and fair in 3 patients. The mean time for bony union was 14.2 weeks. Radiological Rasmussen Scores showed excellent results in 24 patients, good in 32, and fair in 4. Conclusion: The hybrid external fixator is an effective and reliable treatment option for Schatzker Type V and VI fractures, particularly in cases with significant soft tissue damage. It provides favorable functional and radiological outcomes.
