Clinically Relevant Subgroups Among Athletes Who Have Ruptured Their Anterior Cruciate Ligaments: A Delaware‐Oslo Cohort Study
Authors' conclusion
The prevalence of OA in all subgroups is highly concerning.
Study context
- Population
- Individuals with anterior cruciate ligament (ACL) rupture enrolled after resolution of effusion, pain and range of motion impairments and with quadriceps strength ≥70% of the uninvolved limb (45.7% male, mean age 26.2 years)
- Participants
- 293 individuals
- Exposure
- Latent subgroups after ACL rupture
- Outcome
- Radiographic osteoarthritis (OA) (Kellgren/Lawrence grade ≥1) in the involved knee
- Follow-up
- 5 years after injury
Methodological detailsmixture modeling (latent subgroups, probabilistic assignment), chi-square tests
- Mixture modeling (latent subgroups, probabilistic assignment)
