Consistency of patellar spin, tilt and lateral translation side-to-side and over a 1 year period in healthy young males

The purpose of this study was to determine the consistency and symmetry of in vivo measures of patellar spin, tilt, and medial/lateral translation in healthy knees. Patellofemoral joint kinematics were measured bilaterally through a range of loaded knee flexion in 10 active males (aged 19.0 (0.57) years) at baseline, 6, and 12 months using a validated magnetic resonance imaging method. Effects due to time and limb were determined using ANOVA. …
