About this study
Official title: Preventing Knee Stiffness
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.

Questions about this trial
What is this clinical trial studying?
A study testing Patellar Traction in people with Infected Distal Femoral Fractures and Knee Stiffness, run by The Second Hospital of Qinhuangdao.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07864441, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
