Prevalence of trochlea dysplasia in a large cohort

Abstract

Hypothesis/Purpose: The prevalence of trochlea dysplasia is common in different populations. Background The true prevalence of trochlea dysplasia in the general population categorised on gender, race, age and body mass index has been sparse. The purpose of this study was to define the prevalence of trochlea dysplasia based on the latter categories. Study Design: Cohort retrospective study. Methods 1165 skeletal mature healthy femora were obtained from a CT-scan-based modelling system (SOMA). Trochlea dysplasia was measured using Pfirmann’s method. Patient demographics such as age, race and gender were recorded. Results There is an overall prevalence of 4.5% and is commoner in Asian female patients. Conclusion Although there is a lack of consensus with regards to classification of trochlea dysplasia there is an ongoing focus on treatment of trochlea dysplasia. If more funding is to be directed towards these treatment strategies knowing the overall prevalence and burden on patients is essential for funding bodies.
