The L:P ratio was evaluated at five stifle angles (75\u00b0, 96\u00b0, 113\u00b0, 130\u00b0, and 148\u00b0) in 14 cadavers (26 stifle joints) of small dog breeds in order to identify the best stifle angle to measure the L:P ratio. Then the mean \u00b1 SD L:P ratio was calculated for normal stifles and stifles with medial patellar luxation grades 1, 2, and 3 in 194 Pomeranians, 74 Chihuahuas, and 41 Toy or Standard Poodles.<\/jats:p>\n Results: The L:P ratio was the same for all five stifle angles in the cadavers (p = 0.195). It was also not significantly different in the three breeds (p = 0.135), in normal and medial patellar luxation-affected stifles overall (p = 0.354), and in normal and medial patellar luxation-affected joints within each breed (p = 0.19).<\/jats:p>\n Clinical significance: We conclude that a proximo-distal patellar position is not associated with medial patellar luxation in Pomeranians, Chihuahuas, and Toy or Standard Poodles. Thus a longer patellar ligament length does not play a role in the pathophysiology of medial patellar luxation in these small dog breeds.<\/jats:p>","DOI":"10.3415\/vcot-15-02-0028","type":"journal-article","created":{"date-parts":[[2015,6,3]],"date-time":"2015-06-03T07:23:20Z","timestamp":1433316200000},"page":"270-273","source":"Crossref","is-referenced-by-count":12,"title":["Proximo-distal patellar position in three small dog breeds with medial patellar luxation"],"prefix":"10.3415","volume":"28","author":[{"given":"L.
