Background: Distal femur fractures represent a significant orthopedic challenge, requiring optimal fixation techniques to restore knee joint function and promote fracture healing. The choice between Locking Compression Plate (LCP) fixation and Non-Locking Plate fixation significantly impacts functional outcomes. Objective: To compare the functional outcomes of distal femur fractures treated with LCP fixation versus Non-Locking Plate fixation, focusing on knee function, fracture union time, range of motion, and post-operative recovery. Methods: A prospective observational study was conducted at Saraswathi Institute of Medical Sciences involving 60 adult patients (aged 18-70 years) with distal femur fractures. Patients were divided into two groups: 30 treated with LCP fixation and 30 with Non-Locking Plate fixation. Fractures were classified using Muller's classification system. Functional outcomes were assessed using the Hospital for Special Surgery (HSS) knee scoring system. Results: The LCP group demonstrated superior functional outcomes with 83.2% achieving excellent knee scores compared to 75.3% in the Non-Locking Plate group (p=0.004). Mean range of motion was significantly higher in the LCP group (111° ± 18.1) compared to the Non-Locking Plate group (92° ± 17.2) (p=0.0001). LCP fixation was preferred for complex fractures (C1, C2, C3 types), while Non-Locking Plates were more commonly used for simpler fractures. Conclusion: LCP fixation provides superior functional outcomes compared to Non-Locking Plate fixation, particularly for complex distal femur fractures, demonstrating better knee function, improved range of motion, and faster rehabilitation.
