Clinical Trial Summary

This study evaluates the use of a brace in acute anterior cruciate ligament (ACL) injuries in children and adolescents. Half of the participants will receive a so called rebound ACL brace together with a standardized rehab program supervised by a physiotherapist, while the other half will receive only the standardized rehab program supervised by a physiotherapist

Description:

A well known treatment of posterior cruciate ligament injuries in the acute phase is a brace which pushes the tibia anteriorly, and the result of the treatment is often successful with healing of the ligament. Similarly, in anterior cruciate ligament injuries, it is suggested that a rebound ACL brace which pushes the tibia posteriorly can facilitate healing of the ACL. It does not have as successful treatment results as the PCL brace, but the type and location of the ACL injury has in previous studies not been well defined. We will, after having described the localisation and type of ACL injury treat the intervention group with the rebound ACL brace and a standardized rehab program and the control group with standardized rehab program alone.

The randomization is made blockwise of 4, to treatment A= Brace+physiotherapy or B=Physioterapy. The groups are stratified for gender and age (<=14 years and >14 years)
