Who might be able to join this trial:
This trial has several different groups. Depending on their situation, people may be considered for one of the following:
ACL Reconstruction Group:
- Adults aged under 70 who have injured their ACL within the past year and have a planned surgery to reconstruct it
- Have signed a consent form agreeing to take part
ACL No Reconstruction Group:
- Adults aged under 70 who have injured their ACL within the past year and do not have plans for reconstruction surgery
- Have signed a consent form agreeing to take part
Early to Moderate Knee Osteoarthritis (OA) Group:
- Adults aged under 70 who have been diagnosed with early to moderate knee osteoarthritis (a specific grading scale will be used to confirm this)
- People who experience pain in the knee related to activity and knee stiffness
- Have signed a consent form agreeing to take part
Control Group (healthy comparison participants):
- Adults aged under 70 with no significant changes seen on a knee X-ray
- People who have no current knee problems
- Have signed a consent form agreeing to take part
Who may not be able to join:
The following apply to all groups unless otherwise noted:
- People who have had previous knee surgery (for ACL groups, this means surgery before the current knee injury)
- People with serious circulatory or nerve-related complications in the legs
- People with a BMI over 32
- People with a significant joint condition (such as inflammatory or degenerative joint disease) affecting joints other than the knee being studied, as assessed by a clinician
- People who are not able to have an MRI scan — for example, those with a pacemaker or who experience claustrophobia
- People whose leg measurements are too large to fit the MRI knee scanning equipment — specifically, a thigh circumference greater than 73.5 cm (measured 10 cm above the kneecap) or a calf circumference greater than 61.5 cm (for control group participants, the thigh measurement must also be no smaller than 34.3 cm)
- People who report using cannabis, opioids, or other drugs in a way that meets the definition of drug addiction
