Abstract OBJECTIVES: · To determine if patients with knee flexion contracture after distal femur fracture have poorer outcomes than patients who regain full knee extension. · To determine if factors such as patient age, gender, open fracture or implant used favors knee flexion contracture. METHODS: Design: Prospective, multicenter trial Setting: Twenty academic level I trauma centers Patient Selection Criteria: Patients with a distal femur fracture. Patients were evaluated for knee flexion contracture at 3, 6 and 12 months post-operatively. Outcome Measures and Comparisons: SMFA, Bother Index and EQ Health Index scores were recorded. Walking and stair climbing ability were assessed. RESULTS: · 126 patients had radiographic follow up for 12 months. There was clinical follow-up for 99 patients at 3 months, 90 patients at 6 months and 74 pts at 12 months. · Patients with full knee extension had better SMFA scores at 12 months than patients with knee flexion contracture (p = 0.308). · Bother Index (p = 0.29) and EQ Health State (p = 0.12) scores did not demonstrate a difference between patients with or without knee flexion contracture at any time point. · Patients with full knee extension had improved walking ability compared to patients with flexion contracture (p = 0.008). Patients with full knee extension had better stair climbing ability than patients with flexion contracture (p = 0.02). · Only older patient age showed a difference in likelihood of flexion contracture (p = 0.01) The rates of flexion contracture in women versus men (p = 0.51), RIMN versus LLP (p = 0.74) and open versus closed fracture (p = 0.24) were not statistically different. CONCLUSIONS: · Patients with knee flexion contractures after distal femur fracture do worse than patients who regain full extension. · Older patients with distal femur fractures are at greater risk for knee flexion contracture. LEVEL OF EVIDENCE: Level I

Objectives: The main 2 forms of treatment for extraarticular proximal tibial fractures are intramedullary nailing (IMN) and locked lateral plating (LLP). The goal of this multicenter, randomized controlled trial was to determine whether there are significant differences in outcomes between these forms of treatment. Design: Multicenter, randomized controlled trial. Setting: 16 academic trauma centers. Patients/Participants: 108 patients were enrolled. 99 patients were followed for 12 months. 52 patients were randomized to IMN, and 47 patients were randomized to LLP. Intervention: IMN or lateral locked plating. Main Outcome Measurements: Functional scoring including Short Musculoskeletal Functional Assessment, Bother Index, EQ-5Dindex and EQ-5DVAS. Secondary measures included alignment, operative time, range of motion, union rate, pain, walking ability, ability to manage stairs, need for ambulatory aid and number, and complications. Results: Functional testing demonstrated no difference between the groups, but both groups were still significantly affected 12 months postinjury. Similarly, there was no difference in time of surgery, alignment, nonunion, pain, walking ability, ability to manage stairs, need for ambulatory support, or complications. Conclusions: Both IMN and LLP provide for similar outcomes after these fractures. Patients continue to improve over the course of the year after injury but remain impaired even 1 year later. Level of Evidence: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Objectives: The 2 main forms of treatment for distal femur fractures are locked lateral plating and retrograde nailing. The goal of this trial was to determine whether there are significant differences in outcomes between these forms of treatment. Design: Multicenter randomized controlled trial. Setting: Twenty academic trauma centers. Patients/Participants: One hundred sixty patients with distal femur fractures were enrolled. One hundred twenty-six patients were followed 12 months. Patients were randomized to plating in 62 cases and intramedullary nailing in 64 cases. Intervention: Lateral locked plating or retrograde intramedullary nailing. Main Outcome Measurements: Functional scoring including Short Musculoskeletal Functional Assessment, bother index, EQ Health, and EQ Index. Secondary measures included alignment, operative time, range of motion, union rate, walking ability, ability to manage stairs, and number and type of adverse events. Results: Functional testing showed no difference between the groups. Both groups were still significantly affected by their fracture 12 months after injury. There was more coronal plane valgus in the plating group, which approached statistical significance. Range of motion, walking ability, and ability to manage stairs were similar between the groups. Rate and type of adverse events were not statistically different between the groups. Conclusions: Both lateral locked plating and retrograde intramedullary nailing are reasonable surgical options for these fractures. Patients continue to improve over the course of the year after injury but remain impaired 1 year postoperatively. Level of Evidence: Therapeutic Level I.
