However, it is commonly associated with other abnormalities which affect the PFJ. The purpose of this study was to describe the prevalence of associated factors known to affect PFJ in patients undergoing rotational tibial osteotomy and their implication for the correction level.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>All patients with PFJ disorder, who underwent rotational tibial osteotomy between July 2009 and February 2020, were included. Patients were excluded if there were no preoperative computed tomography (CT)\/magnetic resonance imaging (MRI). Scans were analyzed by 2 observers. Parameters of interest were femoral version, tibial torsion, trochlear dysplasia, lateral trochlear inclination (LTI), tibial tuberosity\u2013trochlear groove (TT-TG) distance, Insall-Salvati (IS), and Caton Deschamps Index (CDI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The search resulted in 80 knees, which had a mean femoral version of 21.0 \u00b1 11.7, tibial torsion of 45.9 \u00b1 9.1, TT-TG of 18.3 \u00b1 5.5, and LTI of 11.4 \u00b1 14.7. In total, 42.5% had TT-TG value of \u2265 20 mm. Patella alta\/baja was found in 54% based on CDI or IS &gt;1.2 and &lt;0.8. High-grade trochlear dysplasia was found in 25%.
