Clinical Report: Changes in Body Fat Over Time Following Knee Injuries
Overview
This study investigates the changes in body fat among young athletes following sport-related knee injuries compared to uninjured peers. Findings indicate no significant differences in fat mass gain between the two groups over a 24-month period.
Background
Knee injuries in youth athletes are associated with an increased risk of developing overweight or obesity, which can further elevate the risk for post-traumatic osteoarthritis (PTOA). Understanding the patterns of adiposity change following these injuries is crucial for developing effective prevention strategies.

Key Findings
No significant differences in fat mass gain between injured and uninjured youth over 24 months.
Fat mass changes were minimal at all follow-up time points.
Injured youth had similar adiposity gains compared to uninjured peers.
Findings suggest a potential window for obesity prevention in the post-injury period.
Results did not vary significantly between different types of knee injuries or by sex.
Clinical Implications
The findings indicate that clinicians should monitor body composition in young athletes post-knee injury, as similar adiposity gains may occur regardless of injury status.
Conclusion
The study highlights that adiposity changes in youth following knee injuries do not differ significantly from uninjured peers.
Combined rheumatoid factor and anticitrullinated protein antibody status appeared to modify the association between baseline rheumatoid arthritis disease activity and subsequent cardiovascular events in an international observational cohort.
