Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
After the fracture has been open reduced and internally fixed, there is debate on postoperative management of weight bearing. Weight bearing following fixation is generally restricted for 6 to 12 weeks until radiologic evidence of evidence demonstrates sufficient callous. This restricted weight bearing is primarily due to concerns of implant failure and loss of reduction. A study by Brumback et al. examined intramedullary nail fixation of distal femur fractures and concluded to allow full weight bearing of comminuted femoral shaft fractures with antegrade intramedullary nail. This study led surgeons to accelerate their rehabilitation protocols.
The post-operative weight bearing recommendations for distal femur fractures treated with locking plate vary widely which motivated Granata et al. to evaluate the biomechanics of immediate weight bearing of distal femur fractures treated with locked plate fixation. They found that the fatigue limit of the locked plate constructs was 1.9 times body weight for an average 70-kilogram patient over a simulated 10-week postoperative course. Although this study could not fully support immediate weight bearing due to the fact that femoral loads during gait have been estimated to be around 2 times body weight, it demonstrated adequate hardware fixation with weight bearing.
The benefits of early weight bearing are accelerated functional recovery, increased independence, decreased impact on the family, increased psychological benefits, reduced use of healthcare resources, decreased need for family intervention, and family to take care of the patient. The downside is the strength of fixation, the risk of implant failure, and the risk of loss of reduction. The goals are to evaluate the fracture, the complication rate, the mortality rate, and the risks of healthcare resources that have been used.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Early Weight Bearing
Surgeon based prospective cohort supported in the literature to answer research questions in which surgeons have a preferred treatment type. Early weight bearing are those who are permitted in the post operative instructions to be Weight Bear as tolerated after fracture fixation.
Early Weight Bearing
The design will be a surgeon based prospective cohort supported in the literature to answer research questions in which surgeons may have a preferred treatment type. Each surgeon will treat study subjects by his or her single chosen method (weight bearing as tolerated post operatively versus non weight bearing).
The benefits of early weight bearing are accelerated functional recovery, increased independence, decreased impact on the family, increased psychological benefits, reduced use of healthcare resources, decreased need for family intervention, and family to take care of the patient.
Non Weight Bearing
Surgeon based prospective cohort supported in the literature to answer research questions in which surgeons have a preferred treatment type. Non weight bearing are those who are NOT permitted in the post operative instructions to be Weight Bear after fracture fixation.
Non Weight bearing
The design will be a surgeon based prospective cohort supported in the literature to answer research questions in which surgeons may have a preferred treatment type. Each surgeon will treat study subjects by his or her single chosen method (weight bearing as tolerated post operatively versus non weight bearing).
The benefits of early weight bearing are accelerated functional recovery, increased independence, decreased impact on the family, increased psychological benefits, reduced use of healthcare resources, decreased need for family intervention, and family to take care of the patient.
