The goal of this clinical trial is to compare two types of surgical fixation in patients with specific kinds of distal femur fractures. The main questions it aims to answer is which operation for distal femur fractures is better for efficient return to work and everyday activities.
Fractures of the distal femur are severe and common injuries sustained by Wounded Warriors in combat. Despite advances in implant technology, these injuries continue to have an unacceptably high rate of nonunion (failure to heal) of approximately 20%. This adverse outcome requires additional surgery to achieve fracture healing, which prolongs recovery and further delays return to duty often beyond one year after injury. The goal of this study is to investigate a potential treatment for distal femur fractures that has the potential to improve the likelihood of fracture healing and accelerate return of patient function during the healing process.

RECRUITINGReturn to Work - International Physical Activity Questionnaire (IPAQ) Scores
Completion of the International Physical Activity Questionnaire (IPAQ). The IPAQ is a validated, self-report measure that captures detailed information about participation in a wide range of physical activities, including the number of days and amount of time spent in the previous 7 days. Responses for each type of physical activity are then transformed into the number of Metabolic Equivalent for Tasks (METs), and a METs/week is calculated for each patient. To get a continuous variable score from the IPAQ (MET minutes a week) it is considered walking to be 3.3 METS, moderate physical activity to be 4 METS and vigorous physical activity to be 8 METS. Higher scores meaning more activity.
Time frame: Week 6

Health Related Quality of Life - Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Scores
The National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS) project was initiated to improve the precision of self assessment instruments, reduce respondent burden and enhance the comparability of health outcomes measures. The PROMIS-29 includes seven domains: depression, anxiety, physical function, pain interference, fatigue, sleep disturbance, and ability to participate in social roles and activities. A 5-point Likert scale is used for each question and norm-based total scores (range 0-100) have been calculated so that 50 represents the mean and one standard deviation is 10 points. Additionally, higher scores represent better function.
Time frame: 6-week, 3, 6, 12 months

Change in Numeric Pain Rating
Patients will be asked to rate their current pain on a visual analog scale. In a Numerical Rating Scale (NRS), patients are asked to circle the number between 0 and 10, 0 and 20 or 0 and 100 that fits best to their pain intensity. Zero usually represents 'no pain at all' whereas the upper limit represents 'the worst pain ever possible'.
Time frame: 6-week, 3, 6, 12 months
Change in Pain Inventory (BPI)
pain will be assessed using the Brief Pain Inventory (BPI). The BPI is a commonly used and validated 15-item measure of pain intensity and interference with daily life. The BPI measures how much pain has interfered with seven daily activities, including general activity, walking, work, mood, enjoyment of life, relations with others, and sleep. BPI pain interference is typically scored as the mean of the seven interference items. Pain Score: 1 - 4 = Mild Pain. Worst Pain Score: 5 - 6 = Moderate Pain. Worst Pain Score: 7 - 10 = Severe Pain. Higher scores meaning higher Pain.
Time frame: 6-week, 3, 6, 12 months

Higher scores represent worse PTOA Standard joint space with no evidence of degeneration was set as Grade 0. Normal joint space with the occurrence of osteophytes, subchondral sclerosis, and cysts was set as Grade 1. Joint space narrowing was set as Grade 2. Disappeared joint space was set as Grade 3.
Time frame: 1 year
Isokinetic Knee Flexion/Extension Strength Testing
Knee flexion and extension strength testing will be performed on an isokinetic dynamometer (Biodex Medical Systems, Shirley, NY) with the participant in a seated position with the torso straps and thigh strap (for the tested lower extremity) in place in order to reduce accessory motion and isolate knee flexion and extension performance. The reliability of the knee protocol has been previously established and has been demonstrated to be excellent. The knee strength testing protocol is a concentric-concentric reciprocal protocol with five complete repetitions at 60º/s. Each participant will perform three practice repetitions at 50% maximum effort and three practice repetitions at 100% effort prior to testing for data analysis. Testing will be performed bilaterally for all participants. Average peak moment (averaged across the five repetitions) normalized to percent body weight will be calculated for each (knee flexion/extension).
Time frame: Up to Year 1
Counter-Movement Jump measurement
Patients will be asked to perform a double-leg and single-leg countermovement jump to assess jump height, concentric force development (take-off), and force dissipation (landing) (VALD Force Deck System). Patients will be asked to perform three repetitions of countermovement jump for maximal height off of a force plate followed by landing on the same force plate.
Time frame: Up to Year 1
Single Leg Static and Dynamic Postural Stability Index
The average of three 10-second trials will be collected for data analysis for eyes closed and eyes open. The variable to be analyzed will the standard deviation of resultant ground reaction force across the 10-second trial. Dynamic postural stability will be assessed during a single-leg landing. Patients will be asked to jump forward to the force plate, clear a 30.5 cm hurdle, land on the force plate with their test leg only, stabilize as quickly as possible, and maintain balance with their hands on their hips for ten seconds. A total of three trials will be collected and averaged together for analysis. A stability index based on the three ground reaction force components will be calculated as described previously.
Time frame: Up to Year 1
Triple Hop Performance Assessment
Bilateral assessment of jump performance will be performed during a triple hop (cross-over) for maximum distance. Participants will be provided with a practice trial at 50 percent maximum effort prior to the test trials and testing will begin with non-surgical left first. Participants will begin the jump behind zero-inch line, which marks the starting point. Participants will perform three consecutive jumps off one leg while crossing over the tape with each jump so that the first jump is lateral, the second jump is medial, and the final jump is lateral. Participants will be asked to hold their place at the end of the third jump until their distance is recorded. Three test trials will be assessed for each leg and averaged together for analysis.
Time frame: Up to Year 1
