Health-Related Quality of Life and Psychological Outcomes in Participants with Symptomatic and Non-Symptomatic Knees after ACL Reconstruction.
Johanna M Hoch, Ansley Swann, Rachel Kleis and 3 others
PMID 38313672WHAT IT FOUND
After ACL reconstruction, people with symptomatic knees reported worse quality of life, more fear of activity, and lower resilience than people with non-symptomatic knees.
Physical activity levels did not differ.
Key findings
01Participants classified as symptomatic had worse health-related quality of life and higher fear-avoidance beliefs than participants classified as non-symptomatic.
02Participants classified as symptomatic had lower resilience and higher BMI than participants classified as non-symptomatic.
03Current physical activity and change in physical activity did not differ between groups.

What it does not show
The sample was small: 29 participants, with 17 symptomatic and 12 non-symptomatic. The study was cross-sectional, so it cannot show which factor came first or whether symptoms caused the reported differences. All data were self-reported through an online survey, and participants could not ask clarifying questions. Symptomatic status was based only on KOOS scores, without radiographs or other clinical criteria. The KOOS symptoms could have come from causes other than osteoarthritis. Data were collected during COVID-19, and pandemic restrictions or responder bias may have affected the answers. The authors could not determine whether participants had other lower extremity surgeries after ACL reconstruction within the study timeframe.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that fear avoidance, low resilience, or higher BMI caused symptomatic knees after ACL reconstruction, or that treating them will improve outcomes. This study was a small cross-sectional survey and did not test an intervention.
