Study summary

The goal of this observational study is to prevent keen stiffness health in in Infected Distal Femoral Fractures in Children. This prospective study aimed to compare the effects of early patellar traction versus no patellar traction in children with infectious femoral fractures and bone defects on relieving knee stiffness. We hypothesized that early patellar traction could improve knee stiffness, leading to better knee function. The primary outcome was performance-based knee tests, and the secondary outcome is knee function in children.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
