Hypothesis
What is the prevalence of radiographic trochlear dysplasia in patients with patellar fractures?
Conclusion
There is a significant prevalence of trochlear dysplasia in patients with patellar fractures.
Supporting Evidence
- Trochlear dysplasia was found in 11.5% of patients with patellar fractures.
- High-grade trochlear dysplasia was present in 6.0% of cases.
- All patients with patello-femoral dislocation had trochlear dysplasia.
Takeaway
This study found that many people with patellar fractures also have a condition called trochlear dysplasia, which can affect their knee.
Methodology

Potential Biases
Potential bias due to the exclusion of patients with inadequate imaging.
Limitations
The study lacked a reference group and had a small sample size due to strict imaging requirements.
Participant Demographics
