Ideal attachment points for lateral patellar sling suture in dogs

Data set from a retrospective analysis of the following patient groups: normal large breed dogs large breed dogs with CCL rupture normal small breed dogs small breed dogs with CCL rupture small breed dogs with MPL Coordinate data were sourced from ImageJ2 for 3 landmarks along the trochlear ridge, fabellar centre, best-fit circle centre, and caudal aspect of Blumensaat's line. Blumensaat's line was used to scale, translate and transform all data. Radii were derived between the best-fit centre and fabellar centre and the trochlear landmarks for statistical comparison in a linear mixed model (not shown). Fabellar centre coordinates and best-fit centre coordinates were compared using MANOVA with MV pairwise comparisons (not shown). Comparison of radii from best-fit centre to patellar centre or trochlear ridge for 9 large breed dogs using fluoroscopic images, to show that the trochlear ridge is a reasonable proxy for the patellar centre.
