Hypothesis
Patients with bicruciate injuries would have poorer outcomes than those with single cruciate ligament MLKIs.
Conclusion
Patients with single cruciate ligament injuries had significantly better postoperative outcomes compared to those with bicruciate injuries.
Supporting Evidence
- Patients with single cruciate MLKIs had significantly higher scores for IKDC, Lysholm, and KOOS compared to bicruciate MLKIs.
- Age and type of injury were significant predictors of outcomes.
- 19% of patients had KOOS QoL <44, indicating poor knee function.
Takeaway
If you hurt your knee and only one ligament is damaged, you might heal better than if two or more ligaments are hurt.
Methodology
Cross-sectional cohort study analyzing patient-reported outcomes after surgical treatment of multiligament knee injuries.
Potential Biases
The study was conducted at a single center, which may limit the generalizability of the findings.
Limitations
35% of eligible patients were lost to follow-up and there was no objective assessment of outcomes.
Participant Demographics
55% male, 45% female; mean age at injury was 37 years.
