VAN DER ZEE, Johannes Hans. Lesions in canine stifle joints due to trochleoplasties as treatment for medial patellar luxation. J. S. Afr. Vet. Assoc. [online]. 2015, vol.86, n.1, pp. 01-05. ISSN 2224-9435. http://dx.doi.org/10.4102/JSAVA.V86I1.1245.
Lesions in canine stifle joints after previous trochleoplasty surgery were documented. In four clinical cases arthrotomies were performed due to stifle pain after previous trochlear deepening procedures. A small area of hyaline cartilage remained in the groove of the stifles in cases where previous wedge trochleoplasties had been performed. All of the stifles had significant areas of eburnation on the axial aspect of the medial trochlear ridge. The stifle joints of a dog that was euthanased due to severe irreversible osteo-arthritis were photographed. The dog had undergone previous surgery for patellar luxation and cranial cruciate ligament ruptures. The trochlear grooves in this dog had almost no visible articular cartilage left.
