Abstract

PURPOSE: The bony articular surface contributes to a joint's congruency, and it might be a determinant of structural change. The aim of this longitudinal study was to determine (i) whether the angle of the trochlear groove is associated with the rate of loss of patella cartilage volume for 2 yr and (ii) whether this association is influenced by particular modifiable and nonmodifiable factors. METHODS: A total of 297 community-based adults with no history of knee pathologic disease were recruited at baseline (2003-2004), and 271 of these subjects were reexamined at follow-up (2006-2007). Magnetic resonance imaging was performed at baseline and follow-up to determine the change in patella cart..
