Lesions in canine stifle joints after previous trochleoplasty surgery were documented. Infour clinical cases arthrotomies were performed due to stifle pain after previous trochleardeepening procedures. A small area of hyaline cartilage remained in the groove of the stiflesin cases where previous wedge trochleoplasties had been performed. All of the stifles hadsignificant areas of eburnation on the axial aspect of the medial trochlear ridge. The stifle jointsof 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 ligamentruptures. The trochlear grooves in this dog had almost no visible articular cartilage left.
