PMID 36793558WHAT IT FOUND
Students with a history of anterior knee pain or ACL reconstruction reported significantly higher fear of movement, pain catastrophizing, and fear-avoidance beliefs than healthy peers.
The two injured groups showed similar psychological barriers, suggesting these issues persist long after injury.
Key findings
01Participants with a history of anterior knee pain or ACL reconstruction had significantly worse scores on all psychological questionnaires compared to the healthy group.
02There were no significant differences in psychological barriers between the anterior knee pain and ACL reconstruction groups.
03Individuals with anterior knee pain showed large effect sizes for fear-avoidance and kinesiophobia compared to healthy controls, similar to those with ACL reconstruction.

What it does not show
The study used a cross-sectional design, so it cannot determine if psychological barriers caused the injury or resulted from it. Participants were college-aged students, which may limit generalizability to older adults or different activity levels. Injury history and pain status were self-reported, which introduces potential recall bias. The study did not control for current physical activity levels or detailed pain severity, which could influence psychological scores. Data collection occurred during the COVID-19 pandemic, which may have elevated fear and anxiety levels in all groups, including healthy controls.
The easy way to misread this
Do not assume that patients with anterior knee pain have fewer psychological barriers than those with ACL reconstruction. The study found no significant difference between the two groups, suggesting both require similar attention to fear-avoidance and catastrophizing during rehabilitation.
