High prevalence of femoral and tibial torsional abnormalities in female patients with anterior knee pain resistant to conservative treatment: A CT-based study

Purpose To assess acetabular version (AV) and to determine the prevalence of femoral and tibial torsional abnormalities in female patients with anterior knee pain (AKP) unresponsive to conservative treatment. The study also aimed to evaluate the prevalence of combined abnormalities.Methods Seventy-t...

The study also aimed to evaluate the prevalence of combined abnormalities.Methods Seventy-three AKP female patients resistant to conservative treatment evaluated between 2013 and 2024 were included. Torsional computed tomography (CT) of the lower limbs was performed on all cases, resulting in the evaluation of 146 limbs.

Only 13.0% of limbs had normal ETT, 43.2% showed moderate abnormalities and 43.8% severe abnormalities. FAV was within normal limits in 48.6% of cases, while 26.7% had moderate anteversion, 22.6% severe anteversion and 2.1% retroversion. AV was normal in 82.9% of limbs, with 13.7% showing retroversion and 3.4% anteversion. Only 4.1% of patients exhibited normal across all three parameters, while 8.2% presented combined abnormalities.
