Psychological Readiness and Kinesiophobia Are Not Associated With Effusion-Synovitis in Early Recovery After Anterior Cruciate Ligament Reconstruction.

Faith N Persyn, Natalie L Blake, Corey D Grozier and 4 others

PMID 42586532

WHAT IT FOUND

At 4 to 6 months after ACL reconstruction, the severity of joint inflammation seen on ultrasound did not predict a patient's fear of movement or their psychological readiness to return to sport.

Patients with more swelling were just as ready to return as those with less.

Key findings

01There was no significant difference in kinesiophobia scores between patients with moderate/severe effusion-synovitis and those with absent/mild effusion-synovitis.

02Psychological readiness to return to sport did not differ significantly between groups based on effusion-synovitis severity.

03Sensitivity analyses using different definitions of inflammation severity confirmed that there were no significant associations with psychological outcomes.

What it does not show

The study used a retrospective convenience sample without a priori power calculation, which may limit generalizability. It was cross-sectional, so it cannot determine if inflammation influences psychological outcomes over time or if the relationship changes at different recovery stages. Physical activity levels and rehabilitation status were not documented, so it is unclear if activity-induced swelling confounded the results. The sample size was small (52 participants), and the study was only powered to detect moderate-to-large differences; smaller effects may have been missed.

The easy way to misread this

Do not conclude that joint inflammation has no impact on recovery. This study only looked at the association with psychological scores at a single time point (4-6 months). It does not rule out that inflammation affects physical function, pain, or psychological outcomes at other stages of recovery.
